PPARG and metabolic dysfunction-associated steatotic liver disease: Using western blot analysis, we found that the low dose of MWCNTs or MWCNTs + PbAc significantly decreased the expression levels of p-AMPKα and PPARγ in the livers of NAFLD mice compared to the saline water or single administration of PbAc, and such decreases induced by combined administration of MWCNTs and PbAc were more prominent (Figure 9A, 9B).
