AMPK, ULK1, and the Energy-Stress Response
2026-09-21
The reference study challenges the prevailing view that AMPK uniformly promotes autophagy during energy stress, showing instead that AMPK suppresses ULK1 signaling while preserving the autophagy machinery for later recovery. These findings encourage researchers to distinguish acute autophagy initiation from longer-term cellular protection when interpreting AMPK activation experiments.

Testosterone Bounce in Degarelix-Treated Prostate Cancer
2026-09-16
A retrospective study of 120 patients identified testosterone bounce, defined by recovery from a nadir below 20 ng/dL to a later value of at least 20 ng/dL, as a marker associated with better overall and cancer-specific survival during degarelix therapy. The finding suggests that longitudinal testosterone behavior may complement PSA-based assessment, although prospective validation is needed before clinical implementation.
