Brain structure predicts treatment response to antidepressant and placebo medications, finds study
by King’s College London Neuroanatomical patterns across the dimensions. False discovery rate- (FDR-) corrected voxel-wise comparison of gray-matter volume differences in Dimension 1 (top row) and Dimension 2 (bottom row) versus controls are presented in transverse, sagittal, and coronal sections. Color bar indicates strength of group differences (MIDAS statistic) between MDD and healthy control participants. Credit:...

Predicting correct dosage may improve success of drug repurposing
by Sarah Small, Pennsylvania State University Credit: Cell Reports Medicine (2023). DOI: 10.1016/j.xcrm.2023.101227Before a drug can be used to treat a disease, it must go through a lengthy and expensive trial process to prove both safety and effectiveness. By repurposing already-approved drugs, researchers can cut out the time and expense of the former step—sometimes. According to...

“Glob of randomness” linked to 75% of cancers reined in by novel peptide
By Paul McClure Researchers have developed a peptide (orange) that targets the MYC protein (gray ribbons) to slow cancer progressionMin Xue/UC Riverside Researchers have developed a peptide that targets a previously ‘undruggable’ protein implicated in more than 75% of human cancers and found that it slowed the proliferation of brain cancer cells in the lab. It’s...

Study: A novel cell-penetrating peptide exerts therapeutic effects against ischemic stroke
by Sichuan International Medical Exchange and Promotion Association The Tat-SIRT5-CTM peptide specifically blocked the interaction of SIRT5 with ANXA1, led to SIRT5 degradation and thereby inhibiting SIRT5-mediated desuccinylation of ANXA1, which in turn alleviated microglia-induced neuroinflammation, and eventually improved the survival of neurons subjected to cerebral ischemia and reperfusion injury. Credit: Figure was drawn using...
