The overexpression of the lncRNA prostate cancer gene expression marker 1 (PCGEM1) produces resistance to DOX-induced apoptosis by suppressing the cleavage of caspase - 7 in LNCaP (cancer cells isolated from the lymph node of a patient with prostate cancer) (Fig. 2) [36]. The gene discussed is PCGEM1; the disease is prostate carcinoma.
