The mRNA expression levels of PI3K, AKT, mTOR, and CCND1 were examined in PC3-treated cells by using QRT-PCR, and the results demonstrated that, by down-regulating the expression levels of these genes, chitosan salicylaldehyde/CuFe2O4 significantly affected prostate cancer cell proliferation, progression, and autophagy more than chitosan salicylaldehyde. Here, AKT1 is linked to Familial prostate cancer.
