More recently, Ding et al. demonstrated that SIRT7 depletion in LNCaP and 22RV1 prostate cancer cells significantly reduces the conversion of LC3B-I to LC3B-II, a vital process that results in autophagy, and that SIRT7 knockdown downregulates vimentin, slug, MMP2, and MMP9 in 22Rv1 prostate cancer cells [106]. Here, SIRT7 is linked to prostate cancer.
