Analysis of gene expression in three prostate cancer cell lines presented that MCM was more effective than FCM in downregulating genes related to the epithelial‐mesenchymal transition (EMT), specifically N‐Cadherin and Vimentin, as well as the epidermal growth factor receptor gene (EGFR) and the apoptosis regulator BCL2, with statistical significance (p < 0.001). The gene discussed is BCL2; the disease is prostate carcinoma.
