Metabolism News and Research

RSS

Metabolism is the means by which the body derives energy and synthesizes the other molecules it needs from the fats, carbohydrates and proteins we eat as food, by enzymatic reactions helped by minerals and vitamins.

Novel Targets for Modulating the Gut Microbiota and Human Health

Researchers at the Helmholtz Institute for RNA-based Infection Research and the Julius-Maximilians-Universität in Würzburg have discovered a protein and a class of small ribonucleic acids (sRNAs) in Bacteroides thetaiotaomicron that control the metabolism of sugar.

Bacteria in Lake Mendota Evolve with Changing Seasons

Like Bill Murray in the movie "Groundhog Day," bacteria species in a Wisconsin lake are in a kind of endless loop that they can't seem to shake. Except in this case, it's more like Groundhog Year.

Study Reveals Mechanism Behind T Cells' Cancer-Killing Power in Hypoxia

Immune checkpoint blockades, or ICBs, have revolutionized treatment for various advanced cancers. However, their effectiveness has plateaued due to therapeutic resistance that renders tumor-infiltrating lymphocytes, or TILs, ineffective.

Ancient DNA Reveals Neandertal Gene Flow into Modern Humans

Ancient DNA research suggests that our non-African ancestors mixed with Neandertals about 50,000 years ago, resulting in one to two percent Neandertal DNA in non-African modern humans.
