New genetic variants contribute to the risk of breast cancer in women, study reveals

A new study reveals seventy-two novel genetic variants that are responsible for breast cancer risk. Published in the journals Nature and Nature Genetics, of these 72 variants, 65 are common variants that predispose patients to breast cancer and a further seven variants predispose particularly to estrogen -receptor negative breast cancer - the subcategory of cases that do not respond to hormonal treatments.

Mysterious DNA modification appears more in the brain under stress

With advances in genomics, scientists are discovering additional components of the DNA alphabet in animals. Do these unusual chemical modifications of DNA have a special meaning, or are they just signs that cellular machines are making mistakes?

Study discovers new genetic risk loci linked to children's food allergies

What role do genes play in egg, milk, and nut allergies? A study published in Nature Communications, led by the Max Delbrück Center for Molecular Medicine and Charité - Universitätsmedizin Berlin, has found five genetic risk loci that point to the importance of skin and mucous membrane barriers and the immune system in the development of food allergies.

Queen's University Belfast leads new research to better understand biology of prostate cancer

Queen's University Belfast has led the world's largest research study using a diagnostic test developed by Almac Diagnostics, to better understand the biology of prostate cancer tumors, which could lead to a transformation in how prostate cancer is diagnosed and treated.

Study elucidates how obesity makes breast cancer more aggressive

Obesity leads to the release of cytokines into the bloodstream which impact the metabolism of breast cancer cells, making them more aggressive as a result. Scientists from Helmholtz Zentrum München, Technische Universität München, and Heidelberg University Hospital report on this in 'Cell Metabolism'. The team has already been able to halt this mechanism with an antibody treatment.

Serum metabolites linked to NAFLD may be heritable, research shows

Serum metabolites associated with nonalcoholic fatty liver disease may be heritable, according to research presented this week at The Liver Meeting - held by the American Association for the Study of Liver Diseases.

UGA researchers pinpoint factors that drive sharp rise in breast cancer genetic testing

A sharp rise in the number of women seeking BRCA genetic testing to evaluate their risk of developing breast cancer was driven by multiple factors, including celebrity endorsement, according to researchers at the University of Georgia.

Better post-weaning diet can reverse potential consequences of early-life high-fat exposure

Research has shown that a mother's diet during pregnancy, particularly one that is high-fat, may program her baby for future risk of certain diseases such as diabetes. A new study from nutrition researchers at the University of Illinois shows that switching the offspring to a new diet--a low-fat diet, in this case--can reverse that programming.

New study describes how gene-environment interaction leads to congenital heart defects

Infants of mothers with diabetes have a three- to five-fold increased risk of congenital heart defects. Such developmental defects are likely caused by a combination of genetic and environmental factors.

Penn researchers functionally dissect gene variant linked to FTLD

Seven years ago, Penn Medicine researchers showed that mutations in the TMEM106B gene significantly increased a person's risk of frontotemporal lobar degeneration (FTLD), the second most common cause of dementia in those under 65.

Northwestern scientists discover 'wasabi receptor' for pain in flatworms

A Northwestern University research team has discovered how scalding heat and tissue injury activate an ancient "pain" receptor in simple animals. The findings could lead to new strategies for analgesic drug design for the treatment of humans.

USC study reveals how schizophrenia has biological effect on the entire brain

Some 40 years since CT scans first revealed abnormalities in the brains of schizophrenia patients, international scientists say the disorder is a systemic disruption to the brain's entire communication system.

Most ovarian cancers start in the fallopian tubes, study finds

Most - and possibly all - ovarian cancers start, not in ovaries, but instead in the fallopian tubes attached to them.

Genes that determine skin color studied - new revelations

Human populations vary vastly in skin tones. European populations have been studied and some of the genes that determine skin color have been found. A latest study in a varied African population has found the specific and new genetic variants that could determine skin color and skin pigmentation. The study report is published in the journal Science.
