Autophagy-mediated ferritin degradation, facilitated by the cargo receptor NCOA4, enhances ferroptosis, while decreased NCOA4 expression lowers cellular GSH levels and increases susceptibility [58]

A study in the Biochemical Journal showed that mice given IGF-1 LR3 experienced a 2.5x degree of anabolic muscle-building effects compared to mice receiving stand-alone IGF-1: The administration of insulin-like growth factor-I (IGF-I) via subcutaneously implanted osmotic pumps partially reversed a catabolic state produced by the co-administration of 20 micrograms of dexamethasone/day to 150 g male rats

As a result, the current clinical evidence is still mainly descriptive and correlational, rather than predictive or causal
