Scientists map risk of premature menopause after cancer treatment

The findings, set out in the Journal of the National Cancer Institute, are based on the experience of more than 2,000 young women in England and Wales treated for the cancer over a period of more than 40 years. Previous research has suggested that women with Hodgkin lymphoma who receive certain types of chemotherapy or radiotherapy are at increased risk of going through the menopause early — but there was insufficient information to provide patients with detailed advice. But the new study, led by scientists at The Institute of Cancer Research, London, provides precise estimates of risk for women depending on which treatment types and doses they received and at what age — allowing doctors to give them detailed advice about their risks of future infertility…

Deletion predicts survival in advanced non-small cell lung cancer

The BIM protein can activate the programmed cell death also known as the apoptotic pathway in cells. BIM deletion has been detected in 12.8% of the Asian population but is very rarely observed in the Caucasian population. All NSCLC patients treated with any therapy, targeted or chemotherapeutic, ultimately fail their therapy but at varying times. …

Study identifies protein that helps prevent active tuberculosis in infected patients

The discovery could help doctors identify people who are at the greatest risk for the highly contagious and potentially fatal lung disease, and it could point the way toward new treatment strategies for TB. The study, conducted in partnership with researchers from Harvard University School of Public Health and the University of Michigan School of Medicine, was published in the Aug. 20 online edition of the journal Science Translational Medicine…

Natural killer cells battle pediatric leukemia

Acute lymphoblastic leukemia (ALL) is the most common cancer of childhood. This disease hinders the development of healthy blood cells while cancer cells proliferate. Currently, children with ALL receive chemotherapy for two to three years, exposing them to significant side effects including changes in normal development and future fertility. As a way to avoid these adverse effects, investigators have been researching how to supercharge the body’s innate cancer-fighting ability — a technique called immunotherapy…

Crucial step in DNA repair identified by researchers

Such disorders are caused by faulty DNA repair systems that increase the risk for cancer and other conditions. The findings are published in this week’s Proceedings of the National Academy of Sciences. The study was funded by the National Institute of Environmental Health Sciences. Regents Professor Michael Smerdon and post-doctoral researcher Peng Mao found that when DNA is damaged, a specific protein must first be “unbuckled” to allow easy access for the DNA “repair crew.” Without this unbuckling, entry to the damaged site is hampered by the compact arrangement of genes and protein in chromosomes called chromatin. …

Do gut bacteria rule our minds? In an ecosystem within us, microbes evolved to sway food choices

In an article published this week in the journal BioEssays, researchers from UC San Francisco, Arizona State University and University of New Mexico concluded from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way. Bacterial species vary in the nutrients they need. …
