Solver output
G6PD catalyzes the rate-limiting step of the pentose phosphate pathway (PPP), oxidizing glucose-6-phosphate to 6-phosphogluconolactone while reducing NADP⁺ to NADPH. NADPH is the primary cytosolic reductant required to regenerate glutathione (GSH) from GSSG via glutathione reductase, making G6PD the central hub of cellular antioxidant defense. Adequate NADPH production suppresses oxidative stress, a key driver of macromolecular damage and accelerated aging. Studies in mice and other organisms show that G6PD overexpression extends lifespan and reduces age-associated oxidative damage, while G6PD deficiency leads to increased ROS, accelerated cellular senescence, and shortened healthspan. Additionally, NADPH supports biosynthetic reactions and maintains redox homeostasis in mitochondria, further linking G6PD activity to mitochondrial health and longevity.
GenAge curators classify each gene's normal function as promoting (Pro-Longevity) or opposing (Anti-Longevity) longevity, based on synthesis across studies. Loss-of-function effects can vary from this depending on the manipulation.
Advisor judgment
The model correctly predicted pro_longevity for G6PD in Mus musculus with high confidence (0.78). The mechanistic reasoning is excellent and accurate: G6PD catalyzes the rate-limiting step of the pentose phosphate pathway, producing NADPH which is critical for antioxidant defense via glutathione regeneration. The model correctly references that G6PD overexpression extends lifespan in mice while deficiency leads to increased oxidative stress and shortened healthspan. This aligns with published research showing G6PD transgenic mice have extended lifespan. The key pathways identified are all relevant and correct.
