Researchers show how gene mutations shift and evolve over time in chronic lymphocytic leukemia

Tumors are not factories for the mass production of identical cancer cells, but are, in reality, patchworks of cells with different patterns of gene mutations. In a new study, researchers at Dana-Farber Cancer Institute and the Broad Institute show, more fully than ever before, how these mutations shift and evolve over time in chronic lymphocytic leukemia (CLL) - providing a strobe-like look at the genetic past, present, and future of CLL tumors.

ADAMTS7 enzyme plays a crucial role in coronary heart disease

Scientists investigating how certain genes affect an individual's risk of developing coronary heart disease have identified a new therapeutic target, according to research published today in The American Journal of Human Genetics.

DNA repair mechanisms tied to reproductive aging

Age-related decline in the efficacy of DNA repair may underlie reproductive aging, say researchers.

Study shows importance of lncRNAs for regulation of adipogeneis

Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells. When this regulation is disrupted, white fat cells are unable to accumulate lipid droplets or mature from their precursors.

Probiotics shows promise in reducing both incidence and severity of necrotizing enterocolitis

"Good" bacteria that live in our intestines have been linked with a variety of health benefits, from fighting disease to preventing obesity. In a new study, Kriston Ganguli of Massachusetts General Hospital for Children and Harvard Medical School and her colleagues have discovered another advantage to these friendly microscopic tenants: Chemicals secreted by good bacteria that typically live in the intestines of babies could reduce the frequency and severity of a common and often-lethal disease of premature infants.

FOXC2 vital to epithelial-mesenchymal transition in breast cancer

Researchers have identified a pivotal protein in a cellular transformation that makes a cancer cell more resistant to treatment and more capable of growing and spreading, making it an inviting new target for drug development.

CELF6 genetic mutation may underlie common behaviors seen in people with autism

Scientists at Washington University School of Medicine in St. Louis have identified a genetic mutation that may underlie common behaviors seen in some people with autism, such as difficulty communicating and resistance to change.

Tousled-like kinases play a key role in suppression and activation of herpesviruses

Kaposi's sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV) hide within the worldwide human population. While dormant in the vast majority of those infected, these active herpesviruses can develop into several forms of cancer.

CATT study clarifies value of genetic testing for age-related macular degeneration

New findings from a landmark clinical trial show that although certain gene variants may predict whether a person is likely to develop age-related macular degeneration (AMD), a potentially blinding eye disease that afflicts more than nine million Americans, these genes do not predict how patients will respond to Lucentis- and Avastin-, the two medications most widely used to treat the "wet" form of AMD.

Ability to tune gene activity will permit refined research for drug resistance, cancer

Scientists who built a synthetic gene circuit that allowed for the precise tuning of a gene's expression in yeast have now refined this new research tool to work in human cells, according to research published online in Nature Communications.

New drug delivery system can reduce size of ovarian tumors by as much as 83%

By loading fragile RNA into silicon nanoparticles, researchers from The Methodist Hospital and two other institutions found a new drug delivery system can reduce the size of ovarian tumors by as much as 83 percent -- and stop tumor growth in chemotherapy-resistant ovarian cancer tissue.

Researchers describe novel antiviral property of cholesterol-25-hydroxylase

A team of UCLA-led researchers has identified a protein with broad virus-fighting properties that potentially could be used as a weapon against deadly human pathogenic viruses such as HIV, Ebola, Rift Valley Fever, Nipah and others designated "priority pathogens" for national biosecurity purposes by the National Institute of Allergy and Infectious Disease.

University of Utah geneticists engineer mice that develop clear cell sarcoma

Geneticists led by University of Utah Nobel Prize Laureate Mario R. Capecchi, Ph.D., have engineered mice that develop clear cell sarcoma (CCS), a significant step in better understanding how this rare and deadly soft tissue cancer arises. The mouse model also can potentially speed the development of drugs to target genes that must be activated for the cancer to form.

RNAi effective in treating cancer patients

The new study published in Cancer Discovery, the flagship journal of the American Association of Cancer Research (AACR), involving three Spanish and six American research centres, presents significant results in treating cancer patients with nanoparticles containing ribonucleic acid interference (RNAi) molecules.

Interleukin 6 variant associated with developmental problems after preterm birth in females

In a study to be presented on February 14 between 1:15 p.m., and 3:30 p.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in San Francisco, researchers will report that variation in a gene involved in inflammation is associated with developmental problems after preterm birth in females, but not males.

Berkeley Lab researchers resolve EGFR activation mystery

Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have provided important new details into the activation of the epidermal growth factor receptor (EGFR), a cell surface protein that has been strongly linked to a large number of cancers and is a major target of cancer therapies.

Florida Hospital, Sanford-Burnham and Takeda renew research agreement

Sanford-Burnham Medical Research Institute (Sanford-Burnham) and Florida Hospital announced today that they have renewed a research agreement with Takeda Pharmaceutical Company Limited (Takeda) to extend their collaboration to discover and evaluate new therapeutic approaches to obesity. The collaboration uses a research and drug-development model that creates an early feedback loop in the discovery pipeline.

Two different mechanisms trigger early-onset prostate cancers

While prostate cancer is the most common cancer in elderly Western men it also, but more rarely, strikes patients aged between 35 and 50. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, in collaboration with several other research teams in Germany, have discovered that such early-onset prostate cancers are triggered by a different mechanism from that which causes the disease at a later age.

RNF20 protein required for MLL-rearranged leukemia amplification

Acute myeloid leukemia (AML) is an aggressive blood cancer that is currently incurable in 70% of patients. In a bold effort, CSHL scientists are among those identifying and characterizing the molecular mechanisms responsible for this cancer in order to generate potential new therapeutics.

Study shows effects of maternal obesity on fetuses

In a study to be presented on February 15 between 8 a.m. and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in San Francisco, California, researchers from Tufts Medical Center will present findings showing the effects of maternal obesity on a fetus, specifically in the development of the brain.
