PHF20 transcriptional factor plays a unique role in regulating p53

Researchers at Moffitt Cancer Center and colleagues have identified PHF20, a novel transcriptional factor, and clarified its role in maintaining the stability and transcription of p53, a gene that allows for both normal cell growth and tumor suppression. PHF20, the researchers found, plays a previously unknown and unique role in regulating p53.

Study demonstrates how Elesclomol blocks oxidative phosphorylation in melanoma

A laboratory study led by UNC medical oncologist Stergios Moschos, MD, demonstrates how a new targeted drug, Elesclomol, blocks oxidative phosphorylation, which appears to play essential role in melanoma that has not been well-understood. Elesclomol (Synta Pharmaceuticals, Lexington, MA) was previously shown to have clinical benefit only in patients with normal serum lactate dehydrogenase (LDH), a laboratory test routinely used to assess activity of disease.

Pyruvate kinase M2 fuels tumor growth by influencing H3 histone protein

A metabolic protein that nourishes cancer cells also activates tumor-promoting genes by loosening part of the packaging that entwines DNA to make up chromosomes, a team led by scientists at The University of Texas MD Anderson Cancer Center reports in the Aug. 16 issue of Cell.

Glioblastoma patients with modified PTEN have resistance to EGFR inhibitors

Despite years of research, glioblastoma, the most common and deadly brain cancer in adults, continues to outsmart treatments targeted to inhibit tumor growth.

New role for oncogenic signaling pathway in embryonic stem cell self-renewal

Researchers at Mount Sinai School of Medicine, the University of Manchester, and the MD Anderson Cancer Center have found a new role for an oncogenic signaling pathway in embryonic stem cell (ESC) self-renewal and in reprogramming adult cells into an ESC-state, which will aid in the development of future cancer therapies.

Neurotez receives U.S. patent for Leptin to treat Alzheimer's

Neurotez, Inc. today announced the grant of U.S. Patent number 8,227,408 by the United States Patent and Trademark Office covering the company's lead product candidate, Leptin. The patent protects use of the hormone Leptin for treating a progressive cognitive disease, disorder or condition, such as Alzheimer's disease (AD), resulting from accumulation of an amyloid peptide or for improving resilience of cognitive function by modulating the accumulation of the amyloid peptide in brain.

Research reveals how metformin reduces HCC risk

For every year that a patient with diabetes takes metformin, their risk for hepatocellular carcinoma reduces, say the authors of a study that also sheds light on the cellular pathway it uses.

Researchers identify mechanism responsible for inhibition of AMPK activity in the hypothalamus

In the complex chain of molecular events that underlie eating behaviors and body weight, the AMP-activated protein kinase (AMPK) enzyme has proven to be a critical link.

Potential link between mutant huntingtin, cell loss and cell death in Huntington's disease

Using an in vitro cell model of Huntington's disease (HD), researchers at Florida Atlantic University's Charles E. Schmidt College of Medicine have discovered a novel mechanism and potential link between mutant huntingtin, cell loss and cell death or apoptosis in the brain, which is responsible for the devastating effects of this disease. Apoptosis has been proposed as one of the mechanisms leading to neuronal death in HD.

Scientists use new method to assemble massive catalogue of data on proteins

Scientists at the Novo Nordisk Foundation Center for Protein Research at the University of Copenhagen have used a new method to assemble a massive catalogue of data on proteins. This gives them unprecedented insight into a process called protein phosphorylation.

Study investigates how glucose metabolism affects biochemical signals in cancer cells

Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the "Warburg effect." Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state.

Grb2 switch controls normal signaling through fibroblast growth factor receptor

Once considered merely a passive link between proteins that matter, Grb2 - pronounced "grab2" - actually lives up to its nickname with its controlling grip on an important cell signaling pathway, scientists at The University of Texas MD Anderson Cancer Center report in the June 22 issue of Cell.

Caspase-11 enzyme plays an important role in Legionella infection

New research shows that an enzyme that has long been considered relatively useless to the immune response instead has an important role in setting up immune cells to kill infection-causing bacteria.

Researchers describe germ line functions of par-5 gene

Certain proteins, such as 14-3-3, conserve their basic functions of cell cycle control in diverse organisms, from worms to humans. In a study led by Juli-n Cer-n and Sim- Schwartz Jr, researchers from the Bellvitge Biomedical Research Institute (IDIBELL) and the Research Institute of Vall d'Hebron (VHIR) respectively, have described germ line functions of par-5, which is one of the two 14-3-3 proteins existing in Caenorhabditis elegans, worms used as experimental model in genetic studies.

Study provides novel mechanism of action of anti-cancer compound: perifosine

Aeterna Zentaris Inc. today announced that an article published in the May 2012 issue of Plos One, outlines a novel mechanism of action of the Company's oral anti-cancer compound, perifosine, which could provide a rationale for a novel approach to the treatment of Malignant Pleural Mesothelioma (MMe), an aggressive type of cancer associated with exposure to asbestos.

Human memory: how to improve yours

Many of us wish we had better memories: be it so that we can pass our exams; remember what to buy from the supermarket; or even remember what we went upstairs for!

Hypoxia may be a primary cause of uncontrollable tumor growth in cancers

Low oxygen levels in cells may be a primary cause of uncontrollable tumor growth in some cancers, according to a new University of Georgia study. The authors' findings run counter to widely accepted beliefs that genetic mutations are responsible for cancer growth.

Expression of tyrosine kinases may limit effectiveness of agents against sarcomas

To better understand the signaling pathways active in sarcomas, researchers at Moffitt Cancer Center used state-of-the-art mass spectrometry-based proteomics to characterize a family of protein enzymes that act as "on" or "off" switches important in the biology of cancer. The tyrosine kinases they identified, the researchers said, could act as "drivers" for the growth and survival of sarcomas.
