(Submitter supplied) Background: Global DNA methylation alterations are hallmarks of cancer. The tumor-suppressive TET enzymes, which are involved in DNA demethylation, are decreased in prostate cancer (PCa); in particular, TET2 is specifically targeted by androgen-dependent mechanisms of repression in PCa and may play a central role in carcinogenesis. Thus, identification of key genes targeted by TET2 dysregulation may provide further insight into cancer biology. more...

(Submitter supplied) Prostate cancer is the most common cancer in men. We identified that miR-29 family is the most androgen-responsive miRNA in hormone-refractory prostate cancer cells. For the screening of miR-29b target, we performed microarray analysis in two prostate cancer cells. Because TET2 is the primary target of miR-29 family by our analysis, we also performed TET2 signaling by microarray. In order to investigate the downsteam signals mediated by TET2 and miR-29b, we performed comprehensive analysis of gene expression in positive prostate cancer cell lines after siTET2 or miR-29b treatment.

(Submitter supplied) Prostate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. To investigate the AR signaling, we performed ChIP sequence analysis in AR positive prostate cancer cell line, LNCaP. In addition, we used hormone-refractory prostate cancer model cells, Bicalutamide-resistant (BicR) to explore the differences of androgen signaling in prostate cancer progression.

(Submitter supplied) The clinical course of prostate cancer (PCa) is highly variable, demanding an individualized approach to therapy and robust prognostic markers for treatment decisions. We here present a random forest-based classification model to predict aggressive behaviour of PCa. DNA methylation changes between PCa cases with good or poor prognosis (discovery cohort with n=78) were used as input. The model was validated with data from two independent PCa cohorts from ICGC and TCGA. more...

(Submitter supplied) This study uses whole methylome sequencing to characterize the methylomes of mouse embryonic fibroblasts (MEF's). Two conditions were analyzed, MEF cells with intact TET1/TET2 enzymes (WT) and MEF cells with TET1/TET2 knocked out (DKO). Our results identify sets of differentially methylated genes which are correlated with TET1/TET2 induced expression changes of the corresponding genes.

(Submitter supplied) The tet methylcytosine dioxygenase 2 (TET2) enzyme catalyzes the conversion of the modified DNA base 5-methylcytosine to 5-hydroxymethylcytosine. TET2 is frequently mutated or dysregulated in multiple human cancers, and loss of TET2 is associated with changes in DNA methylation patterns. Here, using newly developed TET2-specific antibodies and the estrogen response as a model system for studying the regulation of gene expression, we demonstrate that endogenous TET2 occupies active enhancers and facilitates the proper recruitment of ERalpha. more...

(Submitter supplied) We performed methylation, hydroxymethylation, and gene expression profiling using MeDIP-seq, hMeDIP-seq, and RNA-seq, respectively, to investigate the role of TET1 and TET2 in MYC-driven tumor maintenance. We compared T-ALL tumor cells before and upon MYC inactivation and revealed genome-wide changes in the DNA methylation and hydroxymethylation patterns. Furthermore, TET1 knock-down or ectopic TET2 expression in T-ALL revealed genome-wide changes in DNA methylation and hydroxymethylation patterns corresponding to changes in gene expression.

(Submitter supplied) DNA methylation analysis of paired prostate tumor and noncancerous tissues was perform in order to identify potential DNA methylation biomarkers for prostate cancer diagnostics and prognosis. Based on comparison of tumors versus noncancerous tissues and cases with and without biochemical disease recurrence (BCR), several gene targets were selected for more detailed analysis. Differences in methylation were further confirmed by means of methylation-specific PCR and significantly correlated with gene expression. more...

(Submitter supplied) BACKGROUND: Promoter hypermethylation coupled with loss of heterozygosity at the same locus results in loss of gene function in many tumor cells. The "rules" governing which genes are methylated during the pathogenesis of individual cancers, how specific methylation profiles are initially established, or what determines tumor type-specific methylation are unknown. However, DNA methylation markers that are highly specific and sensitive for common tumors would be useful for the early detection of cancer, and those required for the malignant phenotype would identify pathways important as therapeutic targets. more...
