Cellular antennae play key role in muscle-to-fat transformation

Like it or not, as we age, our muscle cells are slowly exchanged, one by one, for fat cells. This process quickens when we injure a muscle, and an extreme form of this process is also seen in muscle-wasting diseases such as Duchenne muscular dystrophy (DMD).

Targeting acid metabolite reduces size and spread of breast cancer

It's a metabolite found in essentially all our cells that, like so many things, cancer overexpresses. Now scientists have shown that when they inhibit 20-HETE, it reduces both the size of a breast cancer tumor and its ability to spread to the lungs.

Study sheds light on night work−cancer link

A new study has offered insights into the association between night shift work and increased cancer risk, as well as pointing towards a potential solution. For several years, scientists have thought that disruption to the body’s natural circadian rhythm is accountable for the increased cancer risk, but the mechanisms behind this have not yet been pinpointed.
