Xiao et al. also observed similar phenomena in the testes of STZ-induced diabetic mice and HG-treated GC-1spg cells, and found that BRD7 inhibits Clusterin expression by regulating hypermethylation of the Clusterin promoter in an EZH2-dependent manner, thereby suppressing AMPK signaling to promote ferroptosis and induce DM-related testicular injury [178]. Here, CLU is linked to diabetes mellitus.
