Research finds adenovirus impact on cell's suicide program pave way for new cancer therapy

A novel mechanism used by adenovirus to sidestep the cell's suicide program, could go a long way to explain how tumor suppressor genes are silenced in tumor cells and pave the way for a new type of targeted cancer therapy, report researchers at the Salk Institute for Biological Studies in the Aug. 26, 2010 issue of Nature.

UK scientists receive Royal Society awards for cancer research

Two Cancer Research UK scientists were recently awarded prestigious Royal Society Awards, while a number of Cancer Research UK scientists were elected fellows of the Royal Society and the Academy of Medical Sciences.Dr Tomas Lindahl is the recipient of the Royal Society Copley Medal, the world's oldest prize for scientific achievement, and Professor Stephen West is awarded this year's GlaxoSmithKline Prize and Lecture.

Diets rich in antioxidants, omega-3 fatty acids can help protect people from skin cancer: Study

We all want that summer glow that comes from a day at the beach, but taking in the rays can have long-term implications for our health. Now Dr. Niva Shapira of Tel Aviv University's School of Health Professions suggests a way to make fun in the sun safer ― and it's all in our food.

Experimental drug benefits women with advanced ovarian or breast tumours caused by BRCA gene faults

An experimental drug called olaparib has been shown to shrink tumours in women whose advanced cancers were caused by faults in their BRCA genes.

Scientists identify possible therapeutic strategy for reducing leukemia risk from chemotherapy

A UCSF-led team has discovered at least one key reason why blood stem cells are susceptible to developing the genetic mutations that can lead to adult leukemia. Their finding also may explain, they say, why some other age-related hematological disorders develop.The study, reported in "Cell Stem Cell" and reviewed in Cell Stem Cell and Cell, opens a new frontier for studying the molecular underpinnings of adult leukemia.

Study finds Olaparib can reduce tumor size in ovarian cancer women

Understanding the underlying genetic weakness of certain types of cancer may lead to targeted therapy and provide the key to effective treatment, a new study suggests. An international consortium of researchers has shown that an investigational drug, Olaparib, can reduce the size of tumors in women with advanced hereditary ovarian cancer with BRCA gene mutations.

RPA70 associated with SUMO-specific protease facilitates DNA repair: Research

A team of investigators led by a physician-scientist at The University of Texas MD Anderson Cancer Center has shown for the first time that the small protein SUMO can team up with the replication protein A (RPA) complex to facilitate DNA repair. The study is published in the Aug. 13 edition of the journal Molecular Cell.

Bisphenol A may decrease sperm quality, concentration: Research

In one of the first human studies of its kind, researchers have found that urinary concentrations of the controversial chemical Bisphenol A, or BPA, may be related to decreased sperm quality and sperm concentration.However, the researchers are quick to point out that these results are preliminary and more study is needed. Several studies have documented adverse effects of BPA on semen in rodents, but none are known to have reported similar relationships in humans.

Body’s natural cell suicide program may trigger tumor development: Study

Cancer research springs a surprise. Researchers at Walter and Eliza Hall Institute in Melbourne have found that programmed cell death (apoptosis) or cell suicide plays a role in tumor development. This process is an important phenomenon in our body as it helps remove damaged cells. Now apoptosis has been found to be protective against cancer formation and autoimmune diseases.

Researchers discover tumor suppressor lincRNAs

The recent discovery of more than a thousand genes known as large intergenic non-coding RNAs (or "lincRNAs") opened up a new approach to understanding the function and organization of the genome. That surprising breakthrough is now made even more compelling with the finding that dozens of these lincRNAs are induced by p53 (the most commonly mutated gene in cancer), suggesting that this class of genes plays a critical role in cell development and regulation. Furthermore, the researchers identify one lincRNA in particular (lincRNA-p21), and demonstrate its critical role in suppressing the reading of many genes across the genome following p53 activation.

Researchers discover enzyme crucial for DNA repair

Researchers have discovered an enzyme crucial to a type of DNA repair that also causes resistance to a class of cancer drugs most commonly used against ovarian cancer.Scientists from The University of Texas MD Anderson Cancer Center and the Life Sciences Institute of Zhejiang University in China report the discovery of the enzyme and its role in repairing DNA damage called cross-linking in the Science Express advance online publication of Science.

Study links application of disinfectants in recreational pools to adverse health outcomes

Splashing around in a swimming pool on a hot summer day may not be as safe as you think. A recent University of Illinois study links the application of disinfectants in recreational pools to previously published adverse health outcomes such as asthma and bladder cancer.

Diffused ultraviolet radiation penetrates beach umbrellas

A team of researchers from the University of Valencia (UV) has proven that 34% of ultraviolet radiation filters through under beach umbrellas. According to what is published in the journal Photochemistry and Photobiology, umbrellas intercept the full direct flow that comes from the Sun, but not the diffused radiation that penetrates through from the sides.

CCTP focuses on identifying, testing drugs for cancer stem cell treatment

Cancer and stem cell biology researchers at the University of Colorado are launching the nation's first program focused on identifying and testing drugs that target and destroy cells thought to be at the root of cancer-cancer stem cells (CSCs).The Cancer Stem Cell-Directed Clinical Trials Program (CCTP) is a collaboration between the University of Colorado Cancer Center and the Charles C. Gates Center for Regenerative Medicine and Stem Cell Biology, both located at the University of Colorado School of Medicine.

Essential nutrient in eggs may reduce risk of infant heart defects

A study published in the American Journal of Clinical Nutrition found that a choline-deficient diet is associated with increased risk for heart defects during prenatal development. Choline is an essential nutrient required for normal cell activity, healthy brain and nerve function, liver metabolism and transportation of nutrients throughout the body.

Subtle mutation affecting epigenome may lead to inherited form of mental retardation: Researchers

A subtle mutation affecting the epigenome –- a set of dynamic factors that influence gene activity -- may lead to an inherited form of mental retardation that affects boys, find researchers at Children's Hospital Boston. The disorder, which also involves cleft lip or cleft palate, appears to hinge on an enzyme working in a biological pathway that may offer several potential drug targets.

People with high levels of vitamin B6 and methionine less likiely to develop lung cancer

People with higher blood levels of vitamin B6 and the amino acid methionine appear to have a lower risk of lung cancer, a French study has found. But more research is needed to understand if higher levels of the nutrients directly protect against the disease.

DNA damage caused by UVA radiation leads to melanoma

A new study by researchers at NYU School of Medicine found that UVA radiation damages the DNA in human melanocyte cells, causing mutations that can lead to melanoma. Melanocytes, which contain a substance called melanin that darkens the skin to protect it from the ultraviolet rays of the sun, are more vulnerable to UVA radiation than normal skin cells because they are unable to repair themselves as efficiently.

Key mechanism present in virgin olive oil protects body against breast cancer: Researchers

Researchers at Universitat Autònoma de Barcelona, led by Dr Eduard Escrich, have discovered a key mechanism by which virgin olive oil, in contrast to other vegetable oils, protects the body against breast cancer.

PARP inhibitors may be effective in men with prostate cancer due to BRCA2 alteration: Researchers

The way prostate cancer develops in men who have an altered 'breast cancer gene' is the same route by which breast cancer develops in women with the same mutation, reveals a study published in PLoS Genetics today (Thursday).
