Randomized controlled trials have tested the effect of supplemental coenzyme Q 10 in heart failure patients
28 Wnt signaling was associated with carriage of the A allele of the rs2069502 CDK4 SNP (including a 1.5-fold change in expression of -catenin, a primary modulator of WNT signaling and a concomitant 1.4-fold change in expression of TCF4 , a developmental transcription factor that is a downstream target of WNT (Table 4, Supplementary Figure S4)
The study reported lower risks for several cancers, including hepatocellular, colorectal, breast, and prostate cancers, though it did not find a significant reduction in lung cancer risk.25 So the honest answer is this: current human evidence does not show that NAC causes cancer, but animal and mechanistic research suggests NAC could behave differently depending on cancer type, disease stage, dose, and treatment context
It modulates GABA and serotonin systems involved in pain processing
