Evidence mounts against DHEA use in treating cognitive decline

DHEA supplements are widely-available and touted as a preventive agent for many chronic diseases.

Scientists reveal the genetic determinants of fat storage in cells

New research by the Gladstone Institutes of Cardiovascular Disease (GICD) and the University of California, San Francisco (UCSF), has revealed the genetic determinants of fat storage in cells, which may lead to a new understanding of and potential treatments for obesity, diabetes, and heart disease. While scientists have long understood that lipid droplets contribute to fat build up in cells, the genes involved in droplet biology have been a focus of extensive research.

Unique genetic signature alerts physicians to high-risk breast tumors

A unique genetic signature can alert physicians to high-risk breast tumors that are masquerading as low-risk tumors, according to research at Washington University School of Medicine in St. Louis and collaborating institutions. Although these tumors are apparently estrogen-receptor positive - meaning they should depend on estrogen to grow - they don't respond well to anti-estrogen therapy.
