The biopsy material specimens were investigated in 33 patients, examined for the prostatic cancer suspicion. In accordance to the morphological investigation data, in 15 patients a benign prostatic hyperplasia was verified, and in 18--pancreatic adenocarcinoma. NotI-Microchips of 180 clones of the third chromosome were used for determination of epigenetic changes. In 50 genes of the third chromosome a high rate of the methylation state changes (from 33 to 82%) was noted. Some changed genes take part in cancerogenesis (HMGB1L5, LRRC58, GPR149, DZIP1L, C3orf77, NUDT16) and in the prostatic gland cancer occurrence (BCL6, ITGA9, FBLN2, SOX2, LRRC3B etc.). Dependence of the genes methylation state from the clinic-morphological indices in patients with the prostatic gland cancer, including, the prostate-specific antigen level, the tumor differentiation degree in accordance to Gleason, was not established. Panel, consisting of 16 new potential markers for early and differentiated diagnosis of prostatic gland cancer, was identified: BHLHE40, FOXP1, LOC285205, ITGA9, CTDSPL, FGF12, LOC440944/SETD5, VHL, CLCN2, OSBPL10/ZNF860, LMCD1, FAM19A4, CAND2, MAP4, KY and LRRC58. |
