Perfluoroalkyl substances (PFASs) have received intense scrutiny in recent years because of their persistence in the environment and potential endocrine-disrupting effects. However, their estrogenic activities are controversial, with different studies showing apparently contradictory results. Now, researchers have used a combination of laboratory experiments […]
Using a new technique, a team of researchers has found tiny and previously undetectable 'hot spots' of extremely high stiffness inside aggressive and invasive breast cancer tumors. Their findings suggest, for the first time, that only very tiny regions of a tumor need to stiffen for metastasis to take place. Though still in its infancy, the researc […]
New findings unveil that a 'hidden' layer of regulation by which the intrinsic dynamic ensemble of miRNA processing intermediates can direct the outcome of important biological processes in response to environmental and cellular stimuli in the absence of protein factors. If these processes go awry, then disease could result. Understanding the roles […]
Scientists have discovered a way to stop the growth of glioblastoma, the deadliest form of brain cancer. The finding provides a new tactic in the war against cancer that involves reprogramming the immune system to do what it does best - fight the tumor instead of fueling it.
