Scientists at Southern University of Science and Technology in Shenzhen, China, have identified a new regulator of the mammalian target of rapamycin (mTOR) pathway associated with the growth of colorectal cancer.

Kazia Therapeutics Ltd.'s stock shot up 248% on July 10 after the Sydney-based company reported that paxalisib showed a 3.8-month improvement in overall survival, a 33% improvement, for newly diagnosed unmethylated patients with glioblastoma (GBM) compared to the concurrent standard-of-care arm in the pivotal GBM-Agile phase II/III study.

Scientists at the University of Virginia have discovered an anti-aging mechanism mediated by an enzyme that metabolizes alcohol. Alcohol dehydrogenase, which in Caenorhabditis elegans and yeast replaces the rejuvenating effect of autophagy, would reduce age-associated glycerol levels, also promoting longevity in mice and humans.

Chemoproteomics studies have uncovered multiple potential kinase drug targets in the Plasmodium protozoan that causes malaria, and subsequent screening of approved kinase inhibitor drugs has now thrown up several hits with lethal activity at different stages of the complex life cycle of the parasite. Researchers at the University of Cape Town, South Africa, working with scientists at Glaxosmithkline plc, describe the activity in Plasmodium of one of these kinase inhibitors, the cancer drug sapanisertib, in a paper appearing in Science Translational Medicine, Oct. 19, 2022.

The U.S. NIH’s National Institute on Aging’s Intervention Testing Program has been searching for ways to extend lifespan for more than two decades by now. And in its animal studies, it has been successful multiple times. There are half a dozen drugs, and a few lifestyle interventions, that reliably extend lifespan in one or both sexes by up to 30%. Read more in part four and five of BioWorld’s multipart series on extending the human lifespan.

Scientists at the University of Melbourne and collaborators performed an in-depth metabolic characterization of precursors of exhausted (Tpex) cells in chronic lymphocytic choriomeningitis virus infection. Their results showed that Tpex metabolic attributes strongly contrast with those of exhausted effector (Tex) cells in the same environment.
