Give and take: Cancer chromosomes give the game away

As tumors develop, cancer cells gain and lose so-called 'chromosome arms', changing their response to drugs, a finding which may offer better personalized treatments for 17 types of cancer.

The first roadmap for ovarian aging

Infertility likely stems from age-related decline of the ovaries, but the molecular mechanisms that lead to this decline have been unclear. Now, scientists have discovered, in unprecedented detail, how ovaries age in non-human primates. The findings reveal several genes that could be used as biomarkers and point to therapeutic targets for diagnosing and treating female infertility and age-associated ovarian diseases, such as ovarian cancer, in humans.

Breastfeeding and childbearing linked to lower early menopause risk

Results of a new epidemiological analysis of more than 108,000 women observed a lower risk of early menopause among women who had at least one pregnancy lasting at least six months and among those who had breastfed their infants. Further, risk was lowest among those who breastfed exclusively.

Why eating yogurt may help lessen the risk of breast cancer

One of the causes of breast cancer may be inflammation triggered by harmful bacteria suggest researchers. Scientists advise consuming natural yogurt, which contains beneficial bacteria which dampens inflammation and which is similar to the bacteria found in breastfeeding mothers. Their suggestion is that this bacteria is protective because breast feeding reduces the risk of breast cancer. The consumption of yogurt is also associated with a reduction in the risk of breast cancer.

Editing RNA delivers precision strike on triple-negative breast cancer

An abundance of microRNA-21 predicts lower survival in people with hard-to-treat 'triple-negative' breast cancer. An innovative compound targets the oncogenic sequence and removes it, killing the cancer cells and stopping their spread in a mouse model, while leaving healthy cells untouched.

Missing link in mechanisms underlying fight-or-flight response

We've all felt the effects of an adrenaline rush. Faced with danger, real or perceived, the heart beats faster, breathing quickens and muscles tighten as the body prepares to fight a threat or flee from it.

Refining breast cancer classification by multiplexed imaging

An imaging approach enables the study of breast cancer tissue in greater detail. It uses 35 biomarkers to identify the different cell types in breast tumors and its surrounding area compared to the current standard of testing single markers. This increases the precision of tumor analysis and classification - and improves personalized diagnostics for breast cancer patients.
