Increasing prostate cancer radiosensitivity by miR-7-5p knockdown of anti-apoptotic genes
Despite the success of radiotherapy for prostate cancer treatment, the recent discovery of radiation resistance prevents it from reaching its full potential. This study aims to use hsa-miR-7-5p for the expression of anti-apoptotic genes. The search for anti-apoptotic genes was carried out through databases. The selected genes included XIAP, MCL1, REL, and BIRC3. Our selection was based on the best miRNA because it has a greater impact on genes. The second step involved transfecting the miRNA into a prostate cancer cell line. Subsequently, radiosensitivity was tested using real-time PCR, clonogenic assay, and annexin V flow cytometry. The highest apoptosis rate in the transfected cells was at 0 Gy in hsa-miR-7-5p (28.88 ± 0.80), plenti III (18.81 ± 0.59), and the control group (4.10 ± 1.52) (P<0.001). Also, its rate was at 4 Gy in hsa-miR-7-5p (36.11 ± 1.93), plenti III (26.42 ± 0.42), and the control group (8.79 ± 2.29) (P<0.001). This study showed a decreasing trend in survival with increasing doses. Suppression of anti-apoptotic genes, including XIAP, MCL1, Birc3, and REL, enhanced radiosensitivity by increasing the expression of hsa-miR-7-5p in the PC3 and LNCaP cell lines. Hsa-miR-7-5p is a miRNA that can suppress the expression of anti-apoptotic genes and thus plays an essential role in the process of cell apoptosis. Targeting genes that are associated with apoptosis could potentially enhance the efficacy of treatments for patients with prostate cancer.
