Newswise The same gene variations that make it difficult to stop smoking also increase the likelihood that heavy smokers will respond to nicotine-replacement therapy and drugs that thwart cravings, a new study shows.

The research, led by investigators at Washington University School of Medicine in St. Louis, will appear online May 30 in the American Journal of Psychiatry.

The study suggests it may one day be possible to predict which patients are most likely to benefit from drug treatments for nicotine addiction.

Smokers whose genetic makeup puts them at the greatest risk for heavy smoking, nicotine addiction and problems kicking the habit also appear to be the same people who respond most robustly to pharmacologic therapy for smoking cessation, says senior investigator Laura Jean Bierut, MD, professor of psychiatry. Our research suggests that a persons genetic makeup can help us better predict who is most likely to respond to drug therapy so we can make sure those individuals are treated with medication in addition to counseling or other interventions.

For the new study, the researchers analyzed data from more than 5,000 smokers who participated in community-based studies and more than 1,000 smokers in a clinical treatment study. The scientists focused on the relationship between their ability to quit smoking successfully and genetic variations that have been associated with risk for heavy smoking and nicotine dependence.

People with the high-risk genetic markers smoked an average of two years longer than those without these high-risk genes, and they were less likely to quit smoking without medication, says first author Li-Shiun Chen, MD, assistant professor of psychiatry at Washington University. The same gene variants can predict a persons response to smoking-cessation medication, and those with the high-risk genes are more likely to respond to the medication.

In the clinical treatment trial, individuals with the high-risk variants were three times more likely to respond to drug therapy, such as nicotine gum, nicotine patches, the antidepressant buproprion and other drugs used to help people quit.

Tobacco use is the leading cause of preventable illness and death in the United States and a major public health problem worldwide. Cigarette smoking contributes to the deaths of an estimated 443,000 Americans each year. Although lung cancer is the leading cause of smoking-related cancer death among both men and women, tobacco also contributes to other lung problems, many other cancers and heart attacks.

Bierut and Chen say that the gene variations they studied are not the only ones involved in whether a person smokes, becomes addicted to nicotine or has difficulty quitting. But they contend that because the same genes can predict both heavy smoking and enhanced response to drug treatment, the genetic variants are important to the addiction puzzle.

Its almost like we have a corner piece here, Bierut says. Its a key piece of the puzzle, and now we can build on it. Clearly these genes arent the entire story other genes play a role, and environmental factors also are important. But weve identified a group thats responding to pharmacologic treatment and a group thats not responding, and thats a key step in improving, and eventually tailoring, treatments to help people quit smoking.

When news broke a vial of Ronald Reagans blood was being auctioned, the price quickly jumped to $30,000 as websites and blogs explored a tantalizing possibility: Did this mean the late president could be cloned?

Before mad scientists got the chance to perform a Dolly-the-Sheep experiment with the 40th president, the seller succumbed to criticism and decided to donate the blood to the Ronald Reagan Presidential Foundation. But this should only encourage the cloning speculation because the Gippers DNA is now in the hands of those who would most like to reproduce him: Republicans.

Party officials have been making the pilgrimage to the Reagan Library this year to express their wish to re-create the great man. I believe boldness and clarity of the kind that Ronald Reagan displayed in 1980 offer us the greatest opportunity to create a winning coalition in 2012, vice presidential aspirant Paul Ryan said at the library last week.

Also making the trip were VP hopefuls Marco Rubio and Chris Christie. Like Ronald Reagan, I believe in what this country and its citizens can accomplish, the latter declared. The America I speak of is the America Ronald Reagan challenged us to be.

The man they hope to join on the ticket, Mitt Romney, once boasted he was not trying to return to Reagan-Bush. Now he says the partys standard-bearer should be in the same mold as Ronald Reagan.

But before they go filling that mold by mapping the Reagan genome, Republicans may wish to consider some genetic flaws that party scientists should repair in the cloning process. To make the Reagan clone more compatible with todays Republican Party, a bit of genetic engineering may be in order:

AFL-1: Reagans AFL-1 gene, on the labor chromosome, has a mutation that made him susceptible to workers rights. He said of unions: There are few finer examples of participatory democracy. He said the right to join a union is one of the most elemental human rights. And he said collective bargaining played a major role in Americas economic miracle.

EPA-4: Reagans EPA-4 gene, on the regulatory chromosome, has a protein that can summon anti-industry sympathies. He signed a law establishing efficiency standards for electric appliances and an update to the Safe Drinking Water Act punishing states that didnt meet clean-water standards.

SSA-2 and MDCR-1: These related genes, on the long arm of the retirement chromosome, are problematic. Reagan expanded Social Security in 1983 and imposed taxes on wealthy recipients. He also signed what was at the time the largest expansion of Medicare in its history.

DEBT-1, DEBT-2, DEBT-3: A trio of abnormalities on the fiscal chromosome caused Reagan to increase taxes several times after his initial tax cut, to embrace much higher taxes on investments than current rates and to sign 18 increases in the federal debt limit.

Genetics can help determine whether a person is likely to quit smoking on his or her own or need medication to improve the chances of success, according to research published in today's American Journal of Psychiatry. Researchers say the study moves health care providers a step closer to one day providing more individualized treatment plans to help patients quit smoking.

The study was supported by multiple components of the National Institutes of Health, including the National Institute on Drug Abuse (NIDA), the National Human Genome Research Institute, the National Cancer Institute, and the Clinical and Translational Science Awards program, administered by the National Center for Advancing Translational Sciences.

"This study builds on our knowledge of genetic vulnerability to nicotine dependence, and will help us tailor smoking cessation strategies accordingly," said NIDA Director Nora D. Volkow, M.D. "It also highlights the potential value of genetic screening in helping to identify individuals early on and reduce their risk for tobacco addiction and its related negative health consequences."

Researchers focused on specific variations in a cluster of nicotinic receptor genes, CHRNA5-CHRNA3-CHRNB4, which prior studies have shown contribute to nicotine dependence and heavy smoking. Using data obtained from a previous study supported by the National Heart Lung and Blood Institute, researchers showed that individuals carrying the high-risk form of this gene cluster reported a 2-year delay in the median quit age compared to those with the low-risk genes. This delay was attributable to a pattern of heavier smoking among those with the high risk gene cluster. The researchers then conducted a clinical trial, which confirmed that persons with the high-risk genes were more likely to fail in their quit attempts compared to those with the low-risk genes when treated with placebo. However, medications approved for nicotine cessation (such as nicotine replacement therapies or bupropion) increased the likelihood of abstinence in the high risk groups. Those with the highest risk had a three-fold increase in their odds of being abstinent at the end of active treatment compared to placebo, indicating that these medications may be particularly beneficial for this population.

"We found that the effects of smoking cessation medications depend on a person's genes," said first author Li-Shiun Chen, M.D., of the Washington University School of Medicine, St. Louis. "If smokers have the risk genes, they don't quit easily on their own and will benefit greatly from the medications. If smokers don't have the risk genes, they are likely to quit successfully without the help of medications such as nicotine replacement or bupropion."

According to the Centers for Disease Control and Prevention, tobacco use is the single most preventable cause of disease, disability, and death in the United States. Smoking or exposure to secondhand smoke results in more than 440,000 preventable deaths each year -- about 1 in 5 U.S. deaths overall. Another 8.6 million live with a serious illness caused by smoking. Despite these well-documented health costs, over 46 million U.S. adults continue to smoke cigarettes.

How do you mend a broken heart? Thanks to scientists in Israel, we might soon have an answer.

Dr. Lior Gepstein and his team at Technion-Israel Institute of Technology managed to take skin cells from ailing heart patients and by adding three genes and valproic acid (used to treat epilepsy), they turned the cells into beating heart tissue.

And it was not just any old heart cells, but, according to Gepstein, "heart cells that are healthy, that are young and resemble heart cells at the day that the patient was born."

The researchers put the new beating heart tissue into rat hearts and saw it was not rejected, but seemed to establish connections with the rodents' tissue.

Stem cell experts praised the research as promising but urged people not to expect to be stopping by the clinic for a fresh heart any time soon. Gepstein's researchers say clinical trials should begin within the next 10 years.

MADISON Breast-cancer researchers at the University of Wisconsin-Madison have found that two related receptors in a robust signaling pathway must work together as a team to maintain normal activity in mammary stem cells.

Mammary stem cells produce various kinds of breast cell types. They may also drive the development and growth of malignant breast tumors.

Published recently in the Journal of Biological Chemistry, the research also suggests that a new signaling pathway may be involved, a development that eventually could take cancer-drug manufacturers in a new direction.

"We wanted to know if we could use this knowledge to inform us about what might be the transition that occurs to start tumor growth and maintain it," says senior author Dr. Caroline Alexander, professor of oncology at the McArdle Laboratory for Cancer Research at the School of Medicine and Public Health.

The paper describes new information about the Wnt signaling pathway. Wnt signaling underlies numerous activities in normal development, but when the system is unregulated, cancer often occurs.

"Wnt signaling is very important for both stem cells and tumor growth. We need to know the details of the signaling process so that we can use the positive aspects of Wnt signaling for regenerative medicine, and eliminate the negative cancer-causing aspects," says Alexander, a member of the UW Carbone Cancer Center (CCC).

Regenerative biologists typically add Wnt proteins together with other agents to guide the differentiation of lung, bone and heart stem cells, she notes.

The UW researchers zeroed in on two related Wnt receptors on the cell surface--LRP5 and LRP6. The receptors normally respond to Wnt ligands that approach cells to initiate a signaling cascade inside.

GRAND RAPIDS, MI -- A stem cell treatment investigated for Huntingtons disease holds out hope that scientists will someday be able to reverse damage caused by the degenerative brain disorder.

The technique, which uses reprogrammed skin cells from a Huntingtons patient, successfully restored motor functions in rats, said Dr. Patrik Brundin, a Van Andel Institute researcher who was involved in the study.

Its an interesting step, one weve been hoping for, he said. Its exciting.

The technique also will be tested in treatments for Parkinsons disease, said Brundin, who came to VAI from Sweden in October to lead the institutes Parkinsons research.

Scientists from Sweden, South Korea and the U.S. collaborated on the study, which was published online Monday in the journal Stem Cells.

Brundin said researchers took stem cells derived from the skin of a patient with Huntingtons disease and converted them to brain cells or nerve cells in culture dishes in the lab. The cells were transplanted into the brains of rats that had an experimental form of Huntingtons, and the rats motor functions improved.

The unique features of the (stem cell approach) means that the transplanted cells will be genetically identical to the patient, Jihwan Song, an associate professor at CHA University in Seoul and co-author of the study, said in a statement released by VAI. Therefore, no medications that dampen the immune system to prevent graft rejection will be needed.

Brundin estimated the research might lead to treatments for humans in five to 10 years, although he acknowledged a timeframe is difficult to predict. Researchers are eager to find a new treatment for Huntingtons because there is nothing really powerful to offer currently, he said.

Huntingtons is a genetic disorder affecting one in every 10,000 Americans that slowly diminishes a persons ability to walk, talk and reason. A child of a parent who has Huntingtons has a 50 percent chance of inheriting the gene that causes it.

Medications can relieve some symptoms in some cases, but there are no treatments available that can slow the disease, according to the Huntingtons Disease Society of America.

A male birth control pill might not be so far-fetched, now that Scottish scientists have uncovered a key gene essential for sperm development.

The gene - called Katnal1 - is critical for sperm production because it enables sperm to mature in the testes. Thus, if scientists can somehow regulate this gene with a pill, sperm production will be stalled.

"If we can find a way to target this gene in the testes, we could potentially develop a non-hormonal contraceptive," study author Dr. Lee Smith, a reader in genetic endocrinology at the Medical Research Council Center for Reproductive Health at the University of Edinburgh in Scotland, said in a news release.

Non-hormonal is important, the researchers say, because some conventional male contraceptives that rely on disrupting production of the male hormone testosterone can cause side effects such as mood swings, acne and irritability. The new treatment would also provide an alternative to popular male birth control methods like condoms and vasectomy.

Katnal1 is needed to regulate scaffold-like structures called tubules, the study showed, which forms part of the cells that provide nutrients to developing sperm. When scientists genetically modified mice to not carry this gene, the mice were infertile. The findings are published in the May 24 issue of PLoS Genetics.

Smith said the effects from a drug targeting this gene would be reversible since it stops the sperm at the maturation stage.

"The important thing is that the effects of such a drug would be reversible because Katnal1 only affects sperm cells in the later stages of development, so it would not hinder the early stages of sperm production and the overall ability to produce sperm," he said.

Dr. Allan Pacey, a senior lecturer in andrology at the University of Sheffield in the U.K., told BBC News that a non-hormonal contraceptive for men has been the "Holy Grail" of research for years.

"The gene described by the research group in Edinburgh sounds like an exciting new possible target for a new male contraceptive, but it may also shed light on why some men are sub-fertile and why their sperm does not work properly," Pacey said.

This isn't the only ongoing attempt at finding an effective non-hormonal male birth control. HealthPop reported in January that researchers at the University of North Carolina used high-frequency ultrasound to zap sperm counts in rats, suggesting it might be effective in humans.

Recently approved with conditions by Health Canada, XALKORI is an oral monotherapy for patients with anaplastic lymphoma kinase (ALK)-positive advanced or metastatic non-small cell lung cancer (NSCLC).1 XALKORI is Pfizer Canada's first example of personalized medicine for people with ALK-positive non-small cell lung cancer.

Lung cancer has been one of the most difficult cancers to treat because symptoms typically do not appear until the disease has already reached an advanced stage.2 Even when symptoms appear, they are often mistaken for other health problems further delaying patients from receiving the care they may need.3

As a percentage of all cancer deaths, lung cancer kills more Canadians (27%) than breast cancer (7%), colorectal cancer (12%) and prostate cancer (5%).4

Approximately 70 Canadians are diagnosed with lung cancer every day and 55 die of lung cancer every day.5

"Little has changed in the way lung cancer has been treated in the past 40 years6," says Dr. Normand Blais, Hemato-Oncologist at CHUM - Hpital Notre-Dame in Montreal. "Previously lung cancer was considered a single disease. With the discovery of molecular biomarkers, such as ALK, we now know there are numerous types of lung cancers. New care options for these types of cancers can give hope to those who are or will be diagnosed with them."

Non-small cell lung cancer occurs when malignant cells form in the tissues of the lung.7 Research shows that 54 per cent of lung cancers have molecular biomarkers that drive tumour growth.8 An estimated three to five per cent of non-small cell lung cancers are ALK-positive, a genetic alteration discovered less than five years ago by Japanese researcher Dr. Hiroyuki Mano and his team.9

In ALK-positive lung cancer, a normally dormant gene called ALK is fused with another gene, predominantly EML4.10 This abnormalgene fusion produces a protein that is believed to be a key driver of tumour development in cancers such as non-small cell lung cancer.

The recent discovery of ALK and other lung cancer biomarkers is the basis of an evolution in the approach to management of the disease. As Dr. Blais explains, "Oncologists, such as myself, now have the added responsibility of assessing other tumour traits with our colleagues and considering the requirement for additional molecular tests that may help select therapies for patients."

In the case of XALKORI, using a validated ALK assay, assessment for ALK-positive advanced or metastatic NSCLC should be performed by laboratories with demonstrated proficiency in the specific technology being utilized.1 If it is ALK-positive and advanced (not amenable to curative therapy) or metastatic then patients can be prescribed XALKORI.

But Reviewers Urge Caution in Development and Clinical Use of Adipose Stem Cells

Newswise Philadelphia, Pa. (May 29, 2012) Adipose stem cells (ASCs)stem cells derived from fatare a promising source of cells for use in plastic surgery and regenerative medicine, according to a special review in the June issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).

But much more research is needed to establish the safety and effectiveness of any type of ASC therapy in human patients, according to the article by Dr. Rod Rohrich of University of Texas Southwestern Medical Center, Dallas, and colleagues. Dr. Rohrich is Editor-in-Chief of Plastic and Reconstructive Surgery.

Adipose Stem CellsExciting Possibilities, but Proceed with Caution The authors present an up-to-date review of research on the science and clinical uses of ASCs. Relatively easily derived from human fat, ASCs are "multipotent" cells that can be induced to develop into other kinds of cellsnot only fat cells, but also bone, cartilage and muscle cells.

Adipose stem cells promote the development of new blood vessels (angiogenesis) and seem to represent an "immune privileged" set of cells that blocks inflammation. "Clinicians and patients alike have high expectations that ASCs may well be the answer to curing many recalcitrant diseases or to reconstruct anatomical defects," according to Dr. Rohrich and coauthors.

However, even as the number of studies using ASCs increases, there is continued concern about their "true clinical potential." The reviewers write, "For example, there are questions related to isolation and purification of ASCs, their effect on tumor growth, and the enforcement of FDA regulations."

Dr. Rohrich and coauthors performed an in-depth review to identify all known clinical trials of ASCs. So far, most studies have been performed in Europe and Korea; reflecting stringent FDA regulations, only three ASC studies have been performed in the United States to date.

Many Different Uses, But Little Experience So Far Most ASC clinical trials to date have been performed in plastic surgerya field with "unique privileged access to adipose tissues." Plastic surgeon-researchers have used ASCs for several types of soft tissue augmentation, such as breast augmentation (including after implant removal) and regeneration of fat in patients with abnormal fat loss (lipodystrophy). Studies exploring the use of ASCs to promote healing of difficult wounds have been reported as well. They have also been used as a method of soft tissue engineering or tissue regeneration, with inconclusive results.

In other specialties, ASCs have been studied for use in treating certain blood and immunologic disorders, heart and vascular problems, and fistulas. Some studies have explored the use of ASCs for generating new bone for use in reconstructive surgery. A few studies have reported promising preliminary results in the treatment of diabetes, multiple sclerosis, and spinal cord injury. No serious adverse events related to ASCs were reported in either group of studies.

Although many of the results are encouraging, the reviewers emphasize that all of these applications are in their infancy. Around the world, for all uses, less than 300 patients have been treatedwith no standard protocol for the preparation or clinical applications of ASCs.

ORANGE, Calif.--(BUSINESS WIRE)--

A CHOC Childrens research project, under the direction of Philip H. Schwartz, Ph.D., senior scientist at the CHOC Childrens Research Institute and managing director of the facilitys National Human Neural Stem Cell Resource, has been awarded a $5.5 million grant from the California Institute for Regenerative Medicine (CIRM). The grant will be used to develop a stem cell-based therapy for the treatment of mucopolysaccharidosis (MPS I), a fatal metabolic disease that causes neurodegeneration, as well as defects in other major organ systems.

Based on a number of medical and experimental observations, children with inherited degenerative diseases of the brain are expected to be among the first to benefit from novel approaches based on stem cell therapy (SCT).

Dr. Schwartz explains, While uncommon, pediatric genetic neurodegenerative diseases account for a large burden of mortality and morbidity in young children. Hematopoietic (bone marrow) stem cell transplant (HSCT) can improve some non-neural symptoms of these diseases, but does not treat the deadly neurodegenerative process. Our approach targeting the effects of the disease on organs besides the brain with HSCT and neurodegeneration with a second stem cell therapy specifically designed to treat the brain is a strategy for whole-body treatment of MPS I. Our approach is also designed to avoid the need for immunosuppressive drugs to prevent rejection of the transplanted cells.

This research is designed to lead to experimental therapy, based on stem cells, by addressing two critical issues: early intervention is required and possible in this patient population; and teaching the immune system not to reject the transplanted cells is required. This research also sets the stage for efficient translation of this technology into clinical practice, by adapting transplant techniques that are standard in clinical practice or in clinical trials, and using laboratory cell biology methods that are easily transferrable to clinical cell manufacturing.

Nationally recognized for his work in the stem cell field, Dr. Schwartz research focuses on the use of stem cells to understand the neurobiological causes of autism and other neurodevelopmental disorders.

Named one of the best childrens hospitals by U.S. News & World Report (2011-2012) and a 2011 Leapfrog Top Hospital, CHOC Children's is exclusively committed to the health and well-being of children through clinical expertise, advocacy, outreach and research that brings advanced treatment to pediatric patients.

A UC Irvine stem cell researcher won a $4.8-million grant to fund research toward a treatment for multiple sclerosis.

The California Institute for Regenerative Medicine awarded immunologist Thomas Lane, of the campus' Sue and Bill Gross Stem Cell Research Center, an Early Transitional Award last week to create a new line of neural stem cells to treat multiple sclerosis, according to a UCI press release.

"I am delighted that [the California Institute] has chosen to support our efforts to advance a novel stem cell-based therapy for multiple sclerosis," Peter Donovan, director of the research center, said in the release.

Lane is collaborating with Jeanne Loring, director of the Center for Regenerative Medicine at the Scripps Research Institute in La Jolla, and Claude Bernard, a multiple sclerosis researcher at Monash University in Australia.

The research project "really embodies what [the California Institute] is all about, which is bringing science together to treat horrible diseases like multiple sclerosis," said Lane, who is a professor of molecular biology and biochemistry.

Multiple sclerosis is a central nervous system disease that causes inflammation and a loss of myelin, a fatty tissue that insulates and protects nerve cells.

The three are working on a stem cell treatment that will stop myelin loss while promoting the growth of new myelin to mend damaged nerves.

Loring creates the neural stem cells, said Lane, while he is testing the therapeutic effects the cells have on multiple sclerosis cells in animals.

The stem cells are already having a positive effect and the scientists are trying to understand why. They hope to identify the cells that have the most promise before going to clinical trials.

"I really want to thank the [California Institute] for allowing, and for funding, us," Lane said.

LAGUNA HILLS, Calif., May 29, 2012 /PRNewswire/ --LoneStar Heart Inc., today announced the advancement of a new therapeutic strategy aimed at genetic reprogramming of cardiac fibroblasts into functioning heart muscle cells to treat damage following a heart attack and other forms of heart disease. The announcement follows a study conducted by researchers at the University of Texas Southwestern Medical Center (UT Southwestern), published in the on-line May 13th issue of the journal Nature, demonstrating feasibility of the approach. The company has acquired exclusive worldwide rights to the new technology.

The adult human heart has almost no regenerative capacity. Instead of rebuilding muscle tissue after a heart attack, or myocardial infarction, the injured human heart forms fibrous, non-contractile scar tissue lacking muscle or blood vessels. Fibroblasts account for a majority of cells in the heart and are activated following injury to form this fibrotic scar tissue. Fibrosis impedes regeneration of cardiac muscle cells, and contributes to loss of contractile function, ultimately leading to heart failure and death. Therapeutic strategies to promote new muscle formation, while limiting fibrosis, represent an attractive approach for heart repair.

As reported in Nature, Eric N. Olson, Ph.D., and colleagues from UT Southwestern show that four gene-regulatory proteins GATA4, HAND2, MEF2C, and TBX5 (GHMT) can convert cardiac fibroblasts into beating cardiac-like muscle cells. Introduction of these proteins into proliferating fibroblasts in mice reprograms them into functional cardiac-like myocytes, improving cardiac function and reducing fibrosis and adverse remodeling of the heart following myocardial infarction. Using cell lineage-tracing techniques, the investigators conclude that newly formed cardiac-like muscle cells in GHMT-treated hearts arose from pre-existing cardiac fibroblasts. Cardiac imaging studies confirmed the new technique promoted a dramatic increase in cardiac function that was sustained for at least three months following myocardial infarction.

"These studies establish proof-of-concept for in vivo cellular reprogramming as a new approach for heart repair," said Dr. Olson, professor and chair of molecular biology at UT Southwestern, and a co-founder of LoneStar Heart. "However, much work remains to be done to determine if this strategy might eventually be effective in humans. We are working hard toward that goal."

The new reprogramming strategy may provide a novel means of improving cardiac function following injury, bypassing many of the obstacles associated with cellular transplantation. Prior work by Dr. Olson's group and others has shown that GHMT proteins fulfill similar roles in cardiac gene regulation in a wide range of organisms, including humans, highlighting the potential of these proteins to augment function of the injured human heart. While cellular replacement strategies via the introduction of stem cells or other cell types into injured hearts have shown promise, there have been numerous technical and biological hurdles associated with such approaches.
