Correlation of BRCA2 gene mutation and prognosis as well as variant genes in invasive urothelial carcinoma of the bladder.

Background: This study aimed to investigate the correlation of BRCA2 gene mutation and prognosis as well as variant genes in patients with invasive urothelial carcinoma of the bladder. It predicted and explored the possible mechanism and clinical value of BRCA2 in the occurrence and development of tumors.

Methods: Data sets of patients with bladder cancer were collected from the Cancer Genome Atlas (TCGA) database.

TET1-mediated different transcriptional regulation in prostate cancer.

The recent studies demonstrated that the global 5-hydroxymethylcytosine (5 hmC) level decreased in prostate cancer (PCa) involved the 5-methylcytosine (5 mC) hydroxymethylase, Ten-eleven translocation (TET)1 reduction. 5 hmC and TET1 were both revealed a dual function in bivalent domain associated with developmental regulators in embryonic stem cell model. However, the mechanism underlying the DNA methylation and hydroxymethylation change mediated by TET1 downregulation in PCa remains unclear.
