UCSF researchers lead $10 million research project on pediatric cancer

Researchers at UC San Francisco are leading a five-year, $10 million research project dedicated to pediatric cancer, funded by the first grant of its kind to focus on a molecular pathway that underlies many cancers rather than on a cancer in a particular organ or tissue in the body.

BeyondSpring files two patent applications to expand therapeutic scope of Plinabulin

BeyondSpring Pharmaceuticals, Inc., a clinical stage biopharmaceutical company focused on the development of innovative cancer therapies, today announced that it has filed two new method of treatment patent applications with the United States Patent and Trademark Office to cover methods of treating brain tumors as well as cancers expressing a mutant form of RAS protein through administration of the Company’s lead compound, Plinabulin.

RUB biochemists gain new insights into generation, maintenance of circadian rhythms

Biochemists at the Ruhr-Universität Bochum have gained new insights into the generation and maintenance of circadian rhythms. They demonstrated that the Ras protein is important for setting the phase of such a circadian clock, as its activity determines the period length of the rhythm.

Combination therapies may overcome resistance to targeted cancer drugs

A protein called YAP, which drives the growth of organs during development and regulates their size in adulthood, plays a key role in the emergence of resistance to targeted cancer therapies, according to a new study led by UC San Francisco researchers.

Scientists find possible way to halt a common fault in different cancers

SCIENTISTS have found a possible way to halt one of the most common faults in many types of cancer, according to research presented at the National Cancer Research Institute (NCRI) Cancer Conference in Liverpool today (Wednesday).

Cancer researchers find molecule that irreversibly interferes with KRAS gene

UT Southwestern Medical Center cancer researchers have found a molecule that selectively and irreversibly interferes with the activity of a mutated cancer gene common in 30 percent of tumors.

Researchers unlock secret behind the activation of Ras proteins

A breakthrough discovery into how living cells process and respond to chemical information could help advance the development of treatments for a large number of cancers and other cellular disorders that have been resistant to therapy.

Researchers find biological weakness in the workings of mutated gene involved in human cancers

NYU Langone Medical Center researchers have found a biological weakness in the workings of the most commonly mutated gene involved in human cancers, known as mutant K-Ras, which they say can be exploited by drug chemotherapies to thwart tumor growth.

Scientists explain new family of proteins that appear to play key role in cancer

Scientists have described a new family of proteins that appear to play a key role in cancer and might be targets for future cancer drugs.

Mount Sinai biologist wins NIH Director's New Innovator Awards for High-Risk, High Reward Research

Arvin Dar, PhD, structural and chemical biologist in oncological sciences at the Icahn School of Medicine at Mount Sinai, is one of 41 national recipients of the prestigious National Institutes of Health (NIH) Director's New Innovator Awards for High-Risk, High Reward Research. The award will support Dar's research into Ras-dependent cancers, specifically investigating how to combat mutations in Ras, a protein implicated in at least one of every five cancers.

Researchers uncover mechanism that switches off cell transport regulating proteins

Researchers at the RUB and from the MPI Dortmund have uncovered the mechanism that switches off the cell transport regulating proteins. They were able to resolve in detail how the central switch protein Rab is down-regulated with two "protein fingers" by its interaction partners.

Pairing statins with cyclin-dependent kinase inhibitors might effectively treat melanomas

A novel approach to identifying potential anticancer drug combinations revealed that pairing cholesterol-reducing drugs called statins with cyclin-dependent kinase inhibitors might provide an effective approach to treating intractable melanomas driven by mutations in the NRAS and KRAS gene.

NCI-funded study to identify metabolic vulnerabilities of particularly aggressive cancers

Eileen White, PhD, associate director for basic science at The Cancer Institute of New Jersey and professor of molecular biology and biochemistry at Rutgers, The State University of New Jersey, and colleagues from Princeton University have been awarded a new five-year, $2.4 million dollar research grant from the National Cancer Institute.

Researchers discover alternative mechanism for Ras protein activation

The protein Ras plays an important role in cellular growth control. Researchers have focused on the protein because mutations in its gene are found in more than 30 percent of all cancers, making it the most prevalent human oncogene.

PNAS: Ras proteins bring tension to the phosphate chain

Proteins accelerate certain chemical reactions in cells by several orders of magnitude. The molecular mechanism by which the Ras protein accelerates the cleavage of the molecule GTP and thus slows cell growth is described by biophysicists at the Ruhr-Universit-t Bochum led by Prof. Dr. Klaus Gerwert in the Online Early Edition of the journal PNAS.

Mutations in Ras gene alone may not cause tumours

Despite a huge amount of research effort, the molecular mechanisms that underlie the transition from a "normal" cell to a cancerous cell are only poorly understood. After the discovery of the first cancer-causing genes or oncogenes and the finding that they are mutated forms of normal cellular genes, it was widely believed that a single mutation was enough to cause cancer.

TGen, UA receive NFCR grant to study targeted pancreatic cancer therapies

The Translational Genomics Research Institute (TGen) and the University of Arizona (UA) have received a three-year, $600,000 grant to study targeted cancer therapies from the National Foundation for Cancer Research.
