Catechol-O-methyltransferase (COMT) is a critical enzyme to detoxify the carcinogenic catechol estrogen and the Val158Met polymorphism of COMT could influence its enzymatic activity. Recent epidemiological studies have investigated the correlation of COMT Val158Met polymorphism with endometrial cancer risk; however, the results are inconsistent. To better evaluate the role of COMT Val158Met in endometrial carcinogenesis, we performed this meta-analysis, considering menopausal status, study quality, ethnicity, and source of controls. ⋯ However, no evidence of association was noted in different ethnic groups and sources of controls. In conclusion, our results suggested that the COMT Val/Val genotype might act as a potential endometrial cancer risk factor in postmenopausal women. Further studies are needed to investigate the interactions between COMT Val158Met polymorphism and endometrial cancer in a specific population.

Disc degeneration is strongly associated with back or neck pain, sciatica, and disc herniation or prolapse. It places an enormous economic burden on society and can greatly affect quality of life. Alternative treatment approaches, such as genetic therapies, are urgently needed to slow or reverse the disc degeneration process. ⋯ By constructing an interactive network of the DEGs, we found that mitogen-activated protein family genes and Ras homologous (Rho) family genes - in particular, MAP2K6 and RHOBTB2 - may play important roles in the progression of degeneration of grade III and IV discs, respectively. MAP2K6 and RHOBTB2 may be specific therapeutic molecular targets in the treatment of disc degeneration. However, further experiments are needed to confirm this result.
