Longevity & AgingPRDM16 Protein Fights Cellular Aging by Activating a Key Antioxidant Gene
Researchers at Huazhong University found that PRDM16, a transcriptional regulator, drops significantly in aged organs of mice and humans. When PRDM16 is genetically deleted in mice, senescence markers surge across kidneys, heart, lungs, brain, stomach, and gut—and aging-related organ damage worsens. Conversely, restoring PRDM16 via lentiviral delivery reduces cellular senescence both in cell culture and in living animals. Mechanistically, PRDM16 binds directly to the promoter of GSTM1—a glutathione S-transferase enzyme—boosting glutathione metabolism and shielding DNA from oxidative damage, a primary driver of senescence. The findings point to the PRDM16–GSTM1 axis as a promising therapeutic target for combating age-related diseases.
