Researchers successfully deliver a common blood pressure drug directly to cells’ ‘power plants’

In a study using lab-grown cells, Johns Hopkins Medicine researchers specializing in aging report they have successfully delivered a common blood pressure drug directly to the inner membrane of mitochondria, the "power plants" in the cells of humans, animals, plants and most other organisms.

Researchers provide critical insights into the molecular mechanisms underlying lysophagy

Autophagy is a self-degradation process that cells use to remove unneeded or damaged components. There are several forms of autophagy, including macroautophagy, which is a bulk degradation system used to target materials in the cell's cytosol to organelles called lysosomes for enzymatic breakdown.

MIT researchers use new technique to gather insight into repetitive protein sequences

About 70 percent of all human proteins include at least one sequence consisting of a single amino acid repeated many times, with a few other amino acids sprinkled in. These "low-complexity regions" are also found in most other organisms.

Study unveils a precise model for the stinging organelle of starlet sea anemone

Summertime beachgoers are all too familiar with the painful reality of a jellyfish sting. But how do the stinging cells of jellyfish and their coral and sea anemone cousins actually work? New research from the Stowers Institute for Medical Research unveils a precise operational model for the stinging organelle of the starlet sea anemone, Nematostella vectensis.

Novel blood biomarkers can potentially predict melanoma patients' response to immunotherapy

Melanoma, a type of skin cancer, is often curable when detected and treated in its early stages. However, the disease can rapidly spread to other organs in the body and become deadly. According to the American Cancer Society, more than 7,600 people die of the disease each year in the United States.
