Autophagy News and Research

RSS

Autophagy is a normal process in which a cell destroys proteins and other substances in its cytoplasm (the fluid inside the cell membrane but outside the nucleus), which may lead to cell death. Autophagy may prevent normal cells from developing into cancer cells, but it may also protect cancer cells by destroying anticancer drugs or substances taken up by them.

SARS-CoV-2 virus may enter and replicate in human cells by targeting cellular processes

The SARS-CoV-2 virus may enter and replicate in human cells by exploiting newly-identified sequences within cell receptors, according to work from two teams of scientists.

Study: Phase separated droplets have many important functions in cells

Autophagy is a fundamental cellular process by which cells capture and degrade their own dysfunctional or superfluous components for degradation and recycling.

High-speed atomic force microscopy sheds light on structure, dynamics of intrinsically disordered proteins

Kanazawa University’s pioneering high-speed atomic force microscope technology has now shed light on the structure and dynamics of some of life’s most ubiquitous and inscrutable molecules – intrinsically disordered proteins.

Anti-diarrhea drug could be used to induce cell death in glioblastoma cell lines

The research group led by Dr Sjoerd van Wijk from the Institute of Experimental Cancer Research in Paediatrics at Goethe University already two years ago found evidence indicating that the anti-diarrhea drug loperamide could be used to induce cell death in glioblastoma cell lines.

Researchers reveal identity of the last unknown protein of autophagy

Drs. Nobuo Noda (Director) and Kazuaki Matoba (Senior Researcher) et al. at the Institute of Microbial Chemistry (BIKAKEN, Tokyo, Japan) discovered that Atg9, one of the proteins that function to mediate autophagy, has phospholipid-translocation activity (the lipid scramblase activity) between the two layers of the lipid bilayer and elucidated that the protein's activity brings about autophagosome membrane expansion.

Reducing food intake can reduce risk of liver cancer caused by fatty liver

Liver cancer from too much fat accumulation in the liver has been increasing in many countries including Japan. In order to change this unfortunate state of affairs, it is important to improve the prognosis of non-alcoholic fatty liver disease.

Dietary supplement can support immune system to combat SARS-CoV-2 infections

SPIN (SPermidin and eugenol INtegrator for the contrasting incidence of coronavirus in EU population) is a European project powered by EIT Food that is currently developing a dietary supplement supporting the function of the immune system in the fight against SARS-CoV-2 infections in the population at high risk.

Enzyme SSH1 impairs disposal of damaged tau and mitochondria leaking toxins

In a healthy brain, the multistep waste clearance process known as autophagy routinely removes and degrades damaged cell components - including malformed proteins like tau and toxic mitochondria.

Study shows how cells respond to nutrient deprivation

The idea of the cell as a city is a common introduction to biology, conjuring depictions of the cell's organelles as power plants, factories, roads, libraries, warehouses and more.

Study: PINK1 and Parkin work together to induce selective autophagy

Researchers at TMIMS have revealed that PINK1 (a serine/threonine kinase) and Parkin (a ubiquitin ligating enzyme: E3) work together to ubiquitylate the outer membrane proteins of damaged mitochondria to induce selective autophagy called mitophagy.
