Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Co doped MoS2 as Bifunctional Electrocatalyst for Hydrogen Evolution and Oxygen Reduction Reactions

International Journal of Electrochemical Science, 2019
Pure MoS2 and MoS2 compounds were doped with Co using a hydrothermal method. XRD results indicate that two of the five diffraction peak results at 9.2° and 18.2° may be attributed to low crystallinity of MoS2. The (002) diffraction peaks for the Co-doped

Exploiting metabolic adaptations to overcome dabrafenib treatment resistance in melanoma cells

Molecular Oncology, EarlyView.
We show that dabrafenib‐resistant melanoma cells undergo mitochondrial remodeling, leading to elevated respiration and ROS production balanced by stronger antioxidant defenses. This altered redox state promotes survival despite mitochondrial damage but renders resistant cells highly vulnerable to ROS‐inducing compounds such as PEITC, highlighting redox
