Research study provides supportive evidence for using ATR inhibitors in cancer therapy

A study published in the October issue of Nature Genetics demonstrates that loss of the tumor-suppressor protein p53, coupled with elimination of the DNA-maintenance protein ATR, severely disrupts tissue maintenance in mice.

Proteins play vital role in transferring human genetic code from one cell to another

A Florida State University College of Medicine researcher has solved a century-old mystery about proteins that play a vital role in the transfer of the human genetic code from one cell to another. The discovery could lead to finding new ways to help the body fight a variety of diseases, including cancer.

Misregulation of SPAK protein may contribute to B-cell lymphoma development

A group led by Dr. Michael Teitell at UCLA has demonstrated that misregulation of the protein SPAK may contribute to B-cell lymphoma development. Their report can be found in the October 2009 issue of the American Journal of Pathology.

Moderately elevated levels of ROS positive in fruit flies

It has been known for decades that reactive oxygen species (ROS) - ions or very small molecules that include free radicals - damage cells. But much to their surprise, Jonsson Cancer Center researchers found that in Drosophila, the common fruit fly, moderately elevated levels of ROS are a good thing.

Scientist reveals that selecting optimal radiation dosage for a patient is possible

An international group of scientists has taken the first step on the road to targeting radiotherapy dosage to individual patients by means of their genetic characteristics, a radiation oncologist told Europe's largest cancer congress, ECCO 15 - ESMO 34, in Berlin today (Thursday September 24). Professor Dirk de Ruysscher, from Maastricht University Medical Centre, Maastricht, The Netherlands, said that his team's work might provide the basis for personalised radiotherapy in which, with a simple blood test, doctors may be able to select the optimal radiation dose for a particular patient.

Gene variant shows a strong gender bias for cancer predisposition

Cancer predisposition resulting from the presence of a specific gene variant shows a strong gender bias, researchers at the University of Cincinnati (UC) have demonstrated.

DNage's observational study assesses natural progression of CS in children

Biotech company Pharming Group NV ("Pharming" or "the Company") announced today that its wholly-owned subsidiary DNage has initiated an observational study in children suffering from Cockayne Syndrome (CS).

eChIP genetic technique developed to examine FA proteins with DNA crosslinks

While Fanconi anemia (FA) is a rare and dangerous disease, new laboratory research at The University of Texas M. D. Anderson Cancer Center shows it may lead researchers toward clues in more common diseases, including highly hereditary types of breast cancer.

Yeast mutants may yield new opportunities for anticancer drug development

Until now, the mode of action of nitrogen-containing bisphosphonate (N-BP) cancer drugs, used to relieve bone pain and to prevent skeletal complications in bone metastasis, has been almost entirely unknown. Researchers writing in BioMed Central's open access journal Genome Biology have used 'barcoded' yeast mutants to identify new biological processes involved in the cellular response to N-BPs, opening up opportunities for the development of new anticancer drugs.

Research reveals new protective properties of vitamin C

Researchers at the University of Leicester and Institute for Molecular and Cellular Biology in Portugal studied new protective properties of vitamin C in cells from the human skin, which could lead to better skin regeneration.

Oxidative DNA damage: Primary cause of mutation

A study that tracked genetic mutations through the human equivalent of about 5,000 years has demonstrated for the first time that oxidative DNA damage is a primary cause of the process of mutation - the fuel for evolution but also a leading cause of aging, cancer and other diseases.

Albert Einstein College of Medicine receives $11.2 million NIH grant to study genes associated with longevity

The National Institutes of Health (NIH) has awarded Albert Einstein College of Medicine of Yeshiva University a five-year, $11.2 million grant to study the impact of damage to DNA on aging and disease. Research funded by this grant, and conducted by a consortium of scientists, could reveal the role of genome maintenance systems in delaying aging and will begin to explore novel interventions to maintain health in old age.

Chk1 and Fbx6 play an important role for the regulation of response to chemotherapy

Cell cycle checkpoints act like molecular tripwires for damaged cells, forcing them to pause and take stock. Leave the tripwire in place for too long, though, and cancer cells will press on regardless, making them resistant to the lethal effects of certain types of chemotherapy, according to researchers at the Salk Institute for Biological Studies.

Research study reveals that high-fructose corn syrup is used as a sweetener in beverages

Researchers have established the conditions that foster formation of potentially dangerous levels of a toxic substance in the high-fructose corn syrup (HFCS) often fed to honey bees.

Disrupting the DNA-repair process

Scientists at Dana-Farber Cancer Institute have uncovered the mechanism behind a promising new approach to cancer treatment: damaging cancer cells' DNA with potent drugs while simultaneously preventing the cells from repairing themselves.

Potential new treatment for drug resistant brain tumors

Dr. Karen Newell, Ph. D., the lead researcher for bio technology company Viral Genetics (Pink Sheets: VRAL), will address the 4th Annual Aspen Symposium on Brain Tumor Immuno- and Stem Cell Therapy. Her presentation will highlight the potential for combining chemotherapy with compounds that interfere with the ability of brain tumor cells to generate the energy needed to repair chemotherapy induced DNA damage.
