Zhang and colleagues reveal that GPX4 serves as a critical regulator of NRF2-mediated otoprotection against aminoglycoside-induced hair cell injury. Their findings identify a GPX4-dependent antioxidant mechanism that enables therapeutic activation of NRF2 and provides new insights into strategies for preventing drug-induced hearing loss.

Cancer cachexia is a devastating metabolic syndrome for which there are no approved treatments. Li and colleagues developed an RNA-targeted therapy, which ameliorates cachectic symptoms, reduces inflammation, and extends survival in mouse cancer models. The study provides an approach for treating cancer cachexia and paves the road for clinical studies.
