PHILADELPHIA - It is perhaps impossible to overstate the importance of the tumor suppressor gene p53. It is the single most frequently mutated gene in human tumors. p53 keeps pre-cancerous cells in check by causing cells, among other things, to become senescent aging at the cellular level. Loss of p53 causes cells to ignore the cellular signals that would normally make mutant or damaged cells die or stop growing.
In short, the p53 pathway is an obvious and attractive target for drug developers. But that strategy has so far proven difficult, as most p53 regulatory proteins operate via protein-protein interactions, which make for poor drug targets, as opposed to ones based on enzymes.
Now, a team of researchers from the Perelman School of Medicine, University of Pennsylvania, has identified a class of p53 target genes and regulatory molecules that represent more promising therapeutic candidates.
As Xiaolu Yang, PhD, professor of Cancer Biology and investigator in Penn's Abramson Family Cancer Research Institute, and his team describe in an advance online Nature publication, p53 participates in a molecular feedback circuit with malic enzymes, thereby showing that p53 activity is also involved in regulating metabolism.(The Yang lab identified p53's role in glucose metabolism in the past.)
The new findings, Yang says, suggest that p53 acts as a molecular sensor of metabolic stress and explains how metabolic stress can lead to senescence in cells.
"We uncovered an important regulatory mechanism for p53 as well as an effector mechanism for p53," Yang says.
Significantly, the findings also identify malic enzymes as novel and potentially useful pharmaceutical targets for anticancer therapy, as well as possible mediators of the normal aging process though neither possibility was actually addressed in the current study.
As cells become damaged and precancerous, the p53 protein prevents those cells from continuing towards becoming tumors by causing the cells to senesce. Metabolic cues also regulate senescence, but the molecular relays coupling those two processes -- senescence and metabolism -- remained unknown.

Kraig Biocraft Laboratories Announces the Creation of New Recombinant Spider Silks
LANSING, Mich., Jan. 14, 2013 (GLOBE NEWSWIRE) -- Kraig Biocraft Laboratories, Inc. (KBLB) (the "Company" or "Kraig") announced that researchers, working pursuant to Kraig's collaborative research program, utilizing customized spider silk genetic engineering sequences, succeeded in creating a new type of recombinant spider silk, which the Company is designating as "Big Red."
The "Big Red" silk is currently being spun within the laboratory by transgenicly modified silkworms.
"'Big Red' is a composite fiber," said Company CEO, Kim Thompson. "This new type of fiber was designed to be a combination of spider silk proteins, silkworm silk proteins and protein from an unrelated species. From a genetic perspective, what significantly differentiates this material from our Monster Silk(TM) is the unique spider silk genetic sequence that we used, which we designed to increase strength to weight ratios. Another important difference is the incorporation of a unique protein, which gives the new fiber its designation as 'red.'
"The design for 'Big Red' derived from what we learned about the mechanical characteristics of recombinant spider silk fibers from our work with Monster Silk(TM)," continued Thompson. "Specifically, the new fiber was designed to place more emphasis on tensile strength and slightly less emphasis on elongation. We anticipate that 'Big Red' will be a powerful arrow in our quiver as we move to commercialize Monster Silk(TM) and the Company is hopeful that this new material will follow it in the commercialization pipeline. In my view, the creation of Big Red demonstrates the power of our technology to continue to develop new and exciting materials."
The "Big Red" name comes in part from the fact that the fibers have a slight red cast. Under UV light, the new fibers actually glow bright red.
Thompson further stated, "The successful creation of these new materials once again validates our scientific models. Based upon the observed levels of color expression and the nature of the spider silk genetic configurations used in its creation, the hope is that it will find its own significant niche in the technical textiles marketplace. Preparation for mechanical testing of the new fiber is currently taking place."
About Kraig Biocraft Laboratories, Inc.
Kraig Biocraft Laboratories, Inc. (www.KraigLabs.com) is a fully reporting biotechnology company that has achieved a series of scientific breakthroughs in the area of spider silk technology with implications for the global textile industry.

Research and Markets: 2013 Animal Biotechnology – Technologies, Markets and Companies
DUBLIN--(BUSINESS WIRE)--
Research and Markets (http://www.researchandmarkets.com/research/ft27lp/animal) has announced the addition of Jain PharmaBiotech's new report "Animal Biotechnology - Technologies, Markets and Companies" to their offering.
This report describes and evaluates animal biotechnology and its application in veterinary medicine and pharmaceuticals as well as improvement in food production. Knowledge of animal genetics is important in the application of biotechnology to manage genetic disorders and improve animal breeding. Genomics, proteomics and bioinformatics are also being applied to animal biotechnology.
Transgenic technologies are used for improving milk production and the meat in farm animals as well as for creating models of human diseases. Transgenic animals are used for the production of proteins for human medical use. Biotechnology is applied to facilitate xenotransplantation from animals to humans. Genetic engineering is done in farm animals and nuclear transfer technology has become an important and preferred method for cloning animals.There is discussion of in vitro meat production by culture
Biotechnology has potential applications in the management of several animal diseases such as foot-and-mouth disease, classical swine fever, avian flu and bovine spongiform encephalopathy. The most important biotechnology-based products consist of vaccines, particularly genetically engineered or DNA vaccines. Gene therapy for diseases of pet animals is a fast developing area because many of the technologies used in clinical trials humans were developed in animals and many of the diseases of cats and dogs are similar to those in humans.RNA interference technology is now being applied for research in veterinary medicine
Molecular diagnosis is assuming an important place in veterinary practice. Polymerase chain reaction and its modifications are considered to be important. Fluorescent in situ hybridization and enzyme-linked immunosorbent assays are also widely used. Newer biochip-based technologies and biosensors are also finding their way in veterinary diagnostics.
Biotechnology products are approved by the Center for Veterinary Medicine of the FDA. Regulatory issues relevant to animal biotechnology are described.
Approximately 110 companies have been identified to be involved in animal biotechnology and are profiled in the report. These are a mix of animal healthcare companies and biotechnology companies. Top companies in this area are identified and ranked. Information is given about the research activities of 11 veterinary and livestock research institutes. Important 108 collaborations in this area are shown.
Share of biotechnology-based products and services in 2012 is analyzed and the market is projected to 2022.
The text is supplemented with 34 tables and 5 figures.Selected 250 references from the literature are appended.

A Call for Action: Genetic Testing Before Prescriptions
By Prachiti Dalvi
Structure of Codeine
Codeine is an opioid pain medication; but if you are a poor metabolizer of a particular enzyme (CYP2D6), you will experience no pain relief from this drug. However, if your doctor could administer something called pharmacogenetic testing, she would know to simply give you morphine (an active metabolite of codeine) instead. For now, this kind of testing isnt available.
Mary Relling, PharmD
Mary V. Relling, PharmD, the Chair of Pharmaceutical Sciences at St. Judes Children Hospital spoke about the need to implement pharmacogenetic testingon Thursday, January 10. A number of tests have recently emerged that are ready for prime time. When we know that some drugs may have adverse effects for people with particular genetic phenotypes, it is unethical to prescribe these drugs without knowing the patients genetic status.
However, Relling said there are a number of barriers to integrating pharmacogenetic tests into clinical care: fragmentation of our healthcare system, a focus on sick-care rather than disease prevention, a lack of evidence for clinical utility or cost-effectiveness, complex underlying lab results, and a lack of a centralized system for recording patient information.
The best way to break through these barriers is to conduct testing preemptively, Relling said. We can simply take drop of blood when the baby is born and run genetic tests. Genetic tests are lifetime results. It makes sense to have it in the background, just as we know a patients age, weight, sex, etc., Relling said. The barriers discussed above can be avoided to a certain extent at St. Judes because they have adopted a team approach to patient care and a 100% electronic system for recording patient records.
The growing affordability of genotyping makes using preemptive pharmacogenetic testing more feasible, she said. The cost of sequencing one or two genes in the past will now produce results for 225 genes. Two years ago, theClinical Pharmacogenetics Implementation Consortium (CPIC)studied how tomigrate pharmacogenetic testing from the laboratory into routine patient care. They looked for gene-drug pairs associated with potential risks oflife-threatening toxicity, serious adverse effects, or lack of effectiveness.Eleven of the genes CPIC determined met the threshold for high-risk were found to have profound effects on 33 drugs.
Relling said approximately 48% of patients receiving drugs at St. Judes received orders for at least one of those pharmacogenetically high-risk medications.
She said the question now is how to usegenetic test results rather than whether a genetic test should be ordered. In the coming years, we will have to address how to maintain the fine balance of providing the clinician with enough information to treat the patient and overwhelming the patient with genetic testing results that are difficult to interpret.

Science for the Public, September 10, 2010. David Stipp, author of The Youth Pill: Scientists at the Brink of an Anti-Aging Revolution. discusses how scientific and medical researchers are addressing the issue of aging. As modern populations live longer, it is necessary to understand both the aging process itself and the potential for greater longevity with good health. Mr. Stipp makes a sharp distinction between bogus claims of an easy way to obtain longevity and the very serious research in genetics and other fields suggesting the possibility of extending productive life. He offers a very clear analysis of the scientific data on aging, and he argues the case for more research and better public information on this issue.
