Oncogene has similar biochemical functions in ancestral metazoan and in humans

To find the causes for cancer, biochemists and developmental biologists at the University of Innsbruck, Austria, retraced the function of an important human cancer gene 600 million years back in time. For the first time, they have identified the oncogene myc in a fresh water polyp and they have shown that this oncogene has similar biochemical functions in ancestral metazoan and in humans.

Research suggests a potential means of circumventing drug resistance in breast cancer patients

Overexpression of low-molecular-weight (LMW-E) forms of the protein cyclin E renders the aromatase inhibitor letrozole ineffective among women with estrogen-receptor-positive (ER+) breast cancers, researchers from The University of Texas M. D. Anderson Cancer Center report in Clinical Cancer Research.

Findings point towards new therapeutic approach for breast and prostate cancer

In a new approach to developing treatments for breast cancer, prostate cancer and enlarged hearts, Loyola University Stritch School of Medicine researchers are zeroing in on a workhorse protein called RSK.

Study could lead to non-surgical alternatives for tonsillectomies

Children with obstructive sleep apnea (OSA) may one day be able to have an injection or use a throat spray instead of getting their tonsils removed to cure their snoring, according to a new study from the University of Chicago, which found that a specific gene product may be responsible for the proliferation of adenotonsillar tissue that can cause pediatric OSA.

Research suggests growth factor gene plays a central role in palate development

Cleft palate has been linked to dozens of genes. During their investigation of one of these genes, researchers at Washington University School of Medicine in St. Louis were surprised to find that cleft palate occurs both when the gene is more active and when it is less active than normal.

Study evaluates hepatocyte transplantation as an alternative to liver transplantation

A research team from the National Taiwan University Hospital has evaluated the efficiency of transplanted hepatocyte (liver) cells in animal models severely damaged by two kinds of chemical toxicity to see whether and how transplanted hepatocytes were able to efficiently repopulate the toxin-induced, severely damaged livers.

Global market for oncology drugs is forecast to reach $80 billion by 2050

New Medicine's Oncology KnowledgeBASE (nm/OK) residing at http://nmok.net became available on the Internet 10 years ago and, since then, the oncology field has evolved into one of the most challenging, complex and promising drug development sectors, both in terms of its potential contribution to medicine and to its market opportunities.

Researchers challenge prevailing belief about role of protein in abnormal cell proliferation

In a study to be published this week, a research team is challenging a prevailing belief about the behavior of a human protein linked to the formation of cancer, possibly breathing new life into the search for therapies that will inhibit that protein from "turning on" genes involved in abnormal cell proliferation.

Study: Warburg effect promotes rapid cell proliferation and tumor growth

A team of scientists led by Professor Adrian Krainer, Ph.D., of Cold Spring Harbor Laboratory has discovered molecular factors in cancer cells that boost the production of an enzyme that helps alter the cells' glucose metabolism. The altered metabolic state, called the Warburg effect, promotes extremely rapid cell proliferation and tumor growth. Adrian Krainer, Ph.D.

M. D. Anderson researchers discover mechanism that helps glioblastomas evade immune attack

Cancer-initiating cells that launch glioblastoma multiforme, the most lethal type of brain tumor, also suppress an immune system attack on the disease, scientists from The University of Texas M. D. Anderson Cancer Center report in a paper featured on the cover of the Jan. 15 issue of Clinical Cancer Research.

New findings may yield novel therapies for chronic neurodegenerative diseases

We all have at one time or another experienced the typical signs of an infection: the fever, the listlessness, the lack of appetite. They are orchestrated by the brain in response to circulating cytokines, the signaling molecules of the immune system. But just how cytokines' reach extends beyond the almost impenetrable blood-brain barrier has been the topic of much dispute.

Synta Pharmaceuticals presents preclinical results of STA-9090 at AACR-IASLC Joint Conference

Synta Pharmaceuticals Corp. (NASDAQ: SNTA), a biopharmaceutical company focused on discovering, developing, and commercializing small molecule drugs to treat severe medical conditions, today announced that preclinical results presented at the AACR-IASLC (American Academy of Cancer Research – International Association for the Study of Lung Cancer) Joint Conference based on work done at Synta and at the Dana-Farber Cancer Institute in Boston showed that STA-9090, a potent, synthetic inhibitor of heat shock protein 90 (Hsp90), demonstrated potent activity against 100% of all non-small cell lung cancer cell lines tested, including those with EGFR, HER2 or KRAS mutations including the EGFR T790 mutation that is present in roughly 50% of cases of erlotinib or gefitinib resistance.

CSHL scientist discovers how bookmarking protein triggers leukemia

Each cell inherits genes from its parent as well as epigenetic information - what amounts to an instruction manual that specifies which genes should be activated or "expressed," when and to what level.

Transcription factor promotes stem cell proliferation to repair tissue damage

The master regulator of muscle differentiation, MyoD, functions early in myogenesis to help stem cells proliferate in response to muscle injury, according to researchers at Case Western Reserve University. The study appears online Jan. 4 in the Journal of Cell Biology (www.jcb.org).

ART publishes impressive data on its bioresorbable stent

Arterial Remodeling Technologies (“ART”) announced today that it has disclosed impressive in vivo and in vitro data related to its bioresorbable stent platform—data that validates the Company’s approach to simultaneously balance biocompatibility, biomechanics and bioresorption in a bioresorbable PLA (polylactic acid) stent without altering healing by drug elution from the stent platform.
