Alternative mRNA splicing controls functions of the human H3K27 demethylase UTX/KDM6A

Project description:The UTX/KDM6A gene encodes the UTX histone H3K27 demethylase, which plays an important role in mammalian development and is frequently mutated in cancers and particularly, in urothelial cancers. Using BioID technique, we explored the interactome of different UTX isoforms.

Role of histone demethylase Kdm6a in pancreatic cancer (MoGene-2_0)

Project description:Transcriptional profile of murine Kdm6a null pancreatic cancer cell lines Loss-of-function mutations of KDM6A, an X chromosome encoded histone H3K27 demethylase, are frequent in a broad spectrum of epithelial and hematopoietic malignancies and contribute to oncogenesis with so far poorly characterized mechanisms. Pancreas specific ablation of Kdm6a in mice accelerated Kras-driven cell transformation and compromised survival in a gender specific manner. Female knockout animals were particularly vulnerable and developed aggressive squamous and quasi-mesenchymal tumors with metastatic potential, as opposed to males which developed adenocarcinomas and exhibited a better prognosis. Integration of gene expression studies coupled to ChIP-seq profiling of chromatin modifications demonstrated that loss of Kdm6a caused genome-wide remodeling of bivalent promoters and rewiring of enhancer chromatin to repress endodermal fate by activating c-MYC and TP63 dependent transcriptional programs favoring squamous and quasi-mesenchymal differentiation.

Protein and histone binding profiles from mouse ES cells during differentiation and after Kdm6a RNAi treatment.

Project description:Here we show binding and occupancy profiles for KDM6A, H3K27me3 and H3K4me3 to address the epigenetic regulation of a subset of Rhox genes, Rhox6 and 9, in female and male ES cells during differentiation. To further address a functional role for KDM6A in the epigenetic regulation of Rhox6 and 9, binding profiles for female ES cells treated with a control siRNA and siRNA specific for Kdm6a are shown. We report that two members of the Rhox cluster, Rhox6 and 9, are regulated by de-methylation of histone H3 at lysine 27 by KDM6A, a histone demethylase with female-biased expression. Our results are consistent with other homeobox genes in that Rhox6 and 9 are in bivalent domains prior to embryonic stem cell differentiation and thus poised for activation. In female mouse ES cells KDM6A is specifically recruited to Rhox6 and 9 for gene activation, a process inhibited by Kdm6a knockdown. In contrast, KDM6A occupancy at Rhox6 and 9 is low in male ES cells and knockdown has no effect on expression. Our study implicates Kdm6a, a gene that escapes X inactivation, in the regulation of genes important in reproduction, suggesting that KDM6A may play a role in the etiology of developmental and reproduction-related effects of X chromosome anomalies. ChIP-chip was used to analyze the binding profiles of KDM6A, H3K27me3, and H3K4me3 during differentiation in female and male ES cells. Additionally, ChiP-chip of KDM6A binding in control treated and siRNA treated ES cells is presented.

KDM6A(UTX) is an epigenetic gatekeeper of mTORC1 signalling in cancer

Project description:Large-scale genome sequencing efforts of human tumors identified epigenetic modifiers as one of the most frequently mutated gene class in human cancer. However, how these mutations drive tumor development and progression is largely unknown. Here, we identify the histone demethylase KDM6A as an important tumor suppressor in solid cancers, such as liver cancer and pancreatic cancer. KDM6A-deficient tumors show hyperactivation of mTORC1 signaling, whereas endogenous KDM6A re-expression in established KDM6A-deficient tumors diminishes mTORC1 activity by fostering the expression of crucial negative pathway regulators, such as DEPTOR, TSC1, and TSC2, resulting in tumor regression. Importantly, KDM6A expression in human tumors correlates with mTORC1 activity and KDM6A-deficient tumors exhibit increased sensitivity to mTORC1 inhibition. Hence, our results link KDM6A-dependent epigenetic remodeling to mTORC1 signaling and provide a potential therapeutic strategy for KDM6A-deficient tumors.

Role of histone demethylase Kdm6a in pancreatic cancer (PrimeView)

Project description:Transcriptional profile of human pancreatic cancer cell lines trerated with JQ1 inhibitor. Loss-of-function mutations of KDM6A, an X chromosome encoded histone H3K27 demethylase, are frequent in a broad spectrum of epithelial and hematopoietic malignancies and contribute to oncogenesis with so far poorly characterized mechanisms. Pancreas specific ablation of Kdm6a in mice accelerated Kras-driven cell transformation and compromised survival in a gender specific manner.
