Discovery of mitochondrial protein opens a path to therapeutic advances for heart and Alzheimer's disease if we ever get our support of actual, factual science back

eurekalert.org/news-releases/1

EurekAlert!Discovery of mitochondrial protein by researchers at Lewis Katz School of Medicine at Temple University opens path to therapeutic advances for heart and Alzheimer’s disease(Philadelphia, PA) – Calcium transport into and out of mitochondria – the powerhouses of cells – is central to cellular energy production and cell death. To maintain the balance of calcium within these powerhouses, cells rely on a protein known as the mitochondrial sodium-calcium exchanger, or NCLX. Now, in new research, scientists at the Lewis Katz School of Medicine at Temple University have discovered a novel regulator of NCLX activity, a protein called TMEM65, which helps move calcium out of mitochondria, protecting against harmful calcium overload. The discovery, described online April 8 in the journal Nature Metabolism, is the first to characterize the interaction of TMEM65 with NCLX in mitochondria. “TMEM65 is the first protein identified that is a bona fide interactor and regulator of NCLX,” explained John W. Elrod, PhD, W.W. Smith Chair in Cardiovascular Medicine and Founding Director of the Aging + Cardiovascular Discovery Center at the Lewis Katz School of Medicine and senior investigator on the new study. The discovery could help scientists design new therapeutic agents to combat calcium overload of mitochondria in conditions such as heart failure and Alzheimer’s disease.

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also overexpressed in many types of cancer. This makes it a promising target for cancer therapies. However, drugs that inhibit Plk1 have often proven ineffective.

A 'Third State' Exists Between Life and Death -And That Suggests Your Cells Are Conscious, Some Scientists Say

A growing number of new studies have found that, at least for some cells, death isn't the end, but the beginning of something wholly unexpected.

And now something completely different. Yes sorry, I post various topics (see bio). My apologies to those who only follow me for my anti-fascism. ❤️

Teaching about cells, organelles, cell transport or reproduction, etc.? I have resources to share.I’ve taught high school for many years, SPED to Honors. The differentiation & adaptations I made for SPED became sought after by other students, even at Honors level. I've worked hard at developing a helpful sequence of ideas, embedded vocabulary support, step-by-step graphics, and analogies.
