Research describes how gene BRCA1 plays vital role in DNA repair

Scientists at the University of Birmingham are a step closer to understanding the role of the gene BRCA1. Changes in this gene are associated with a high risk of developing breast and ovarian cancer.

Continuous errors in damaged DNA repair may lead to tumor formation

A group of researchers at Osaka University found that if DNA damage response (DDR) does not work when DNA is damaged by radiation, proteins which should be removed remain instead, and a loss of genetic information can be incited, which, when repaired incorrectly, will lead to the tumor formation.

AstraZeneca, MedImmune to provide update on extensive oncology pipeline at ASCO 2016

AstraZeneca and its global biologics research and development arm, MedImmune, will provide an update on their extensive oncology pipeline at the annual meeting of the American Society of Clinical Oncology in Chicago, USA, on 3-7 June 2016.

Effective chemotherapeutic drug may induce permanent hearing loss in Cockayne syndrome individuals

The chemotherapy drug cisplatin can kill cancer, but it can also cause permanent hearing loss.

Food deprivation may help treat fatty liver disease

Scientists at Helmholtz Zentrum München have new information on what happens at the molecular level when we go hungry. Working with the Deutsches Zentrum für Diabetesforschung and the Deutsches Krebsforschungszentrum they were able to show that upon deprivation of food a certain protein is produced that adjusts the metabolism in the liver.

Novel animal model helps understand mechanisms that lead to multiple myeloma

Researchers at Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine have developed an animal model that allows them to better understand the mechanisms that lead to the development of multiple myeloma, a hematologic cancer of plasma cells, and the amyloidosis that sometimes accompanies it. The study was published in the journal Scientific Reports.

Combination of existing chemotherapy drugs can reduce breast cancer stem cells, improve survival

Two existing chemotherapy drugs appear to be a powerful pair in targeting errant stem cells that are making breast cancer and enabling its spread and recurrence, scientists report.

New class of cancer-driver gene may serve as unique therapeutic targets, biomarkers in TNBC

The discovery of long non-coding RNA (lncRNA) has dramatically changed the understanding of the biology of diseases such as cancer. The human genome contains about 20,000 protein-coding genes - less than 2 percent of the total - but 70 percent of the genome is made into non-gene-encoding RNA.

Newly discovered player in epigenetic regulation closely linked to known cancer promoters

If genes form the body's blueprint, then the layer of epigenetics decides which parts of the plan get built. Unfortunately, many cancers hijack epigenetics to modulate the expression of genes, thus promoting cancer growth and survival.

Intestinal bacteria can be used to reduce cancer risk, reveals UCLA study

Researchers have shown that various types of intestinal bacteria might be factors in both causing and preventing obesity, and in other conditions and diseases. Now, a UCLA study suggests that it could also potentially be used to reduce the risk for some types of cancer.

Scientists use FAN1 knockout mice to refine detailed mechanisms involved in damaged DNA repair

Like jewels in a vault, our precious genetic material is stored in the nucleus of a cell--sequestered away from potentially damaging cellular components and toxins so that no harm can come to it. Yet over the course of a life moving through this world, our DNA does get damaged, and our cells have a host of complicated repair mechanisms to deal with such injuries.

Study may help identify unborn children at higher risk for birth defects

Researchers at the University of Toronto have discovered a novel function performed by the breast cancer 1 protein (BRCA1), which regulates DNA repair. Well known for the role it plays in breast and ovarian cancer, this study revealed that the BRCA1 protein actually plays a much broader biological role, particularly in protecting the developing embryo from the damaging effects of reactive oxygen species (ROS).

Tumor suppressor p53 gene twice as likely to be defective in autistic children

A large study by researchers with the UC Davis MIND Institute has found that a gene whose role is to suppress cellular damage from environmental stressors is nearly twice as likely to be defective in children with autism spectrum disorder (ASD), and that the deficit is also present in their fathers.

Common genetic defect in beta cells may underlie both known forms of diabetes

New research by Dr. Sylvie Lesage, scientist at Maisonneuve-Rosemont Hospital and associate research Professor at University of Montreal, just published in the prestigious international scientific journal Nature Genetics, has discovered that a common genetic defect in beta cells may underlie both known forms of diabetes.

Mutated gene GT198 has strong potential in early diagnosis of breast cancer

When mutated, a gene known for its ability to repair DNA, appears to instead cause breast cancer, scientists report.

Cell-based tests reveal no activity in cells exposed to vapour from Vype ePen

A series of cell-based tests developed to compare the biological impact of cigarette smoke with e-cigarette vapour revealed no activity in cells exposed to vapour from Vype ePen, a commercially available e-cigarette.

Clinical review examines benefit of RT in breast cancer patients with BRCA1, BRCA2 mutations

In light of conflicting and inconclusive clinical data on the benefit of radiation therapy in cancer patients with the BRCA1 and BRCA2 mutation, a clinical review examined the current status of data regarding BRCA1 and BRCA2 deficiency and radiation therapy sensitivity and a potential strategy to intensify the effects of radiation therapy (RT) by poly(ADP-ribose) polymerase inhibitors (PARPi), the pharmacologic drugs under investigation as monotherapy for the treatment of breast cancer in patients with BRCA1 and BRCA2 mutations.

CTRC study provides new insight into how Angelina Jolie gene functions in normal breast tissue

Scientists from the Cancer Therapy & Research Center in San Antonio today (March 4) published work that provides deeper insight into how the Angelina Jolie gene, BRCA1, functions in normal breast tissue and how its loss results in breast cancer.

Researchers reveal link between mitochondrial dysfunction and Fuchs' Endothelial Corneal Dystrophy

Researchers at Schepens Eye Research Institute of Massachusetts Eye and Ear have shown a link between mitochondrial dysfunction in corneal endothelial cells and the development of Fuchs' Endothelial Corneal Dystrophy.

New research identifies key enzyme linked to age-related increases in cancer and inflammation

For the first time, researchers have shown that an enzyme key to regulating gene expression -- and also an oncogene when mutated -- is critical for the expression of numerous inflammatory compounds that have been implicated in age-related increases in cancer and tissue degeneration, according to new research from the Perelman School of Medicine at the University of Pennsylvania.
