Cancer Research: Dietary intervention primes triple-negative breast cancer for targeted therapy ♦ Can protein 14-3-3 sigma prevent or kill breast cancer tumors?

Spending more leisure time sitting was associated with a higher risk of total cancer risk in women, and specifically with multiple myeloma, breast, and ovarian cancers, according a new study.
Combining chemotherapy with new drugs that target a protein that helps cancer cells to withstand chemotherapy could drastically improve treatment, according to new research.
A diet that starves triple-negative breast cancer cells of an essential nutrient primes the cancer cells to be more easily killed by a targeted antibody treatment, scientists report.
Every parent knows the maxim 'feed a cold, starve a fever.' In cancer, however, exactly how to feed or starve a tumor has not been easy to determine. A new study has shown that a simple molecule called 14-3-3 sigma could be one answer for explaining cancer metabolism, the chemical process by which a tumor forms, grows or dies.
Moderate hormone suppression may be enough in thyroid cancer Moderate suppression of thyroid-stimulating hormone, which drives thyroid cancer, may be as beneficial as more extreme hormone suppression, a study of long-term thyroid cancer outcomes shows. Extreme TSH suppression is associated with increased side effects including osteoporosis and heart rhythm irregularities.
