Postmenopausal breast cancer risk decreases rapidly after starting reg. physical activity
Postmenopausal women who in the past four years had undertaken regular physical activity equivalent to at least four hours of walking per week had a lower risk for invasive breast cancer compared with women who exercised less during those four years, according to data published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

Stanford researchers uncover cancer-causing mechanism behind powerful human oncogene
A protein present at high levels in more than half of all human cancers drives cell growth by blocking the expression of just a handful of genes involved in DNA packaging and cell death, according to a new study by researchers at the Stanford University School of Medicine.

Venom gets good buzz as potential cancer-fighter (video)
Bee, snake or scorpion venom could form the basis of a new generation of cancer-fighting drugs, scientists will report. They devised a method for targeting venom proteins specifically to malignant cells while sparing healthy ones, which reduces or eliminates side effects that the toxins would otherwise cause. Their study is part of the 248th National Meeting of the American Chemical Society. A brand-new video on the research is available at http://www.youtube.com/watch?v=GRsUi5UrH7k&feature=youtu.be.

Synthetic molecule makes cancer self-destruct
Researchers from The University of Texas at Austin and five other institutions have created a molecule that can cause cancer cells to self-destruct by ferrying sodium and chloride ions into the cancer cells. These synthetic ion transporters, described this week in the journal Nature Chemistry, confirm a two-decades-old hypothesis that could point the way to new anticancer drugs while also benefitting patients with cystic fibrosis.

Scientists demonstrate long-sought drug candidate can halt tumor growth
Scientists at The Scripps Research Institute have disrupted the function of MYC, a cancer regulator thought to be 'undruggable.' The researchers found that a credit card-like molecule they developed somehow moves in and disrupts the critical interactions between MYC and its binding partner.

How breast cancer usurps the powers of mammary stem cells
During pregnancy, certain hormones trigger specialized mammary stem cells to create milk-producing cells essential to lactation. Scientists at the University of California, San Diego School of Medicine and Moores Cancer Center have found that mammary stem cells associated with the pregnant mammary gland are related to stem cells found in breast cancer.

Malaria medicine chloroquine inhibits tumor growth and metastases
A recent study by investigators at VIB and KU Leuven has demonstrated that chloroquine also normalizes the abnormal blood vessels in tumors. This blood vessel normalization results in an increased barrier function on the one hand -- thereby blocking cancer cell dissemination and metastasis -- and in enhanced tumor perfusion on the other hand, which increases the response of the tumor to chemotherapy.

Bisphosphonates for osteoporosis not associated with reduced breast cancer risk
An analysis of data from two randomized clinical trials finds that 3-4 years of treatment with bisphosphonates to improve bone density is not linked to reduced risk of invasive postmenopausal breast cancer.

Aberrant mTOR signaling impairs whole body physiology
The protein mTOR is a central controller of growth and metabolism. Deregulation of mTOR signaling increases the risk of developing metabolic diseases such as diabetes, obesity and cancer. In the current issue of the journal Proceedings of the National Academy of Sciences, researchers from the Biozentrum of the University of Basel describe how aberrant mTOR signaling in the liver not only affects hepatic metabolism but also whole body physiology.

Editing HPV's genes to kill cervical cancer cells
Using the genome editing tool known as CRISPR, Duke University researchers were able to selectively silence two genes in human papilloma virus that are responsible for the growth and survival of cervical carcinoma cells. After silencing the two HPV genes, the cancer cell's normal self-destruct machinery went into action.

Cancer categories recast in largest-ever genomic study
New research partly led by UC San Francisco-affiliated scientists suggests that one in 10 cancer patients would be more accurately diagnosed if their tumors were defined by cellular and molecular criteria rather than by the tissues in which they originated, and that this information, in turn, could lead to more appropriate treatments.

University of Minnesota research finds key piece to cancer cell survival puzzle
An international team led by Eric A. Hendrickson of the University of Minnesota and Duncan Baird of Cardiff University has solved a key mystery in cancer research: What allows some malignant cells to circumvent the normal process of cell death that occurs when chromosomes get too old to maintain themselves properly?

Cell mechanics may hold key to how cancer spreads and recurs
Cancer cells that break away from tumors to go looking for a new home may prefer to settle into a soft bed, according to new findings from researchers at the University of Illinois. Some particularly enterprising cancer cells can cause a cancer to spread to other organs or evade treatment to resurface after a patient is thought to be in remission. The researchers found that these tumor-repopulating cells may lurk quietly in stiffer cellular environments, but thrive in a softer space.
