(Submitter supplied) Epigenetic gene regulation in various oncogenic pathways is currently an important focus of cancer research. The PI3K pathway plays a pivotal role in hepatocellular carcinoma, but the significance of histone modification in the PI3K pathway-dependent hepatotumorigenesis remains unknown. We used microarrays to investigate the oncogenic gene regulation by histone demethylase Kdm3a under PI3K signaling activation in the liver.

(Submitter supplied) Histone lysine (K) residues, which are modified by methyl- and acetyl-transferases, diversely regulate RNA synthesis. Unlike the ubiquitously activating effect of histone K acetylation, the effects of histone K methylation vary with the number of methyl groups added and with the position of these groups in the histone tails. Histone K demethylases (KDMs) counteract the activity of methyl-transferases and remove methyl group(s) from specific K residues in histones.KDM3A (also known as JHDM2A or JMJD1A) is an H3K9me2/1 demethylase. more...

(Submitter supplied) We identified KDM3A, a demethylase of histone H3K9me1/2, as a positive regulator for hippo target genes. We found that H3K27ac upregulation is highly correlated with gene activation, but not H3K4me3; and transcription repression of certain TEAD1 target genes, such as BBC3, is important for the pathway function. KDM3A knockout caused upregulation of H3K9me2 mainly on TEAD1-binding enhancers rather than gene bodies, leading to decrease of H3K27ac and TEAD1 binding on enhancers and impaired transcription.

(Submitter supplied) Ewing Sarcoma is the second most common solid pediatric malignant neoplasm of the bone and soft tissue. Driven by EWS/Ets, or rarely variant, oncogenic fusions, Ewing Sarcoma is a biologically and clinically aggressive disease with a high propensity for metastasis. Our laboratory has previously identified the Jumonji-domain H3K9 me 1/2 histone demethylase KDM3A as a novel oncogene downstream of EWS/Fli1, the most common oncofusion in Ewing Sarcoma. more...

(Submitter supplied) Our RNA sequencing analysis revealed that the JIB-04 treatment altered the expression of genes that are involved in the cell cycle, p53 signaling pathway, and apoptosis, and are also related to several cancers including hepatocellular carcinoma. JIB-04 also altered the expression of genes involved in various signaling pathways such as the FoxO signaling pathway, the PI3K-Akt signaling pathway, which is crucial for the proliferation and maintenance of hepatocellular carcinoma cells.

(Submitter supplied) Using a siRNA screen we identified the histone demethylase enzyme KDM3A as a potential positive regulator of ER signalling in breast cancer. To interrogate the full extent of KDM3A regulation on ER signalling we assessed basal and estrogen (E2)- stimulated global gene expression changes in KDM3A-depleted MCF-7 cells by microarray analysis using the Illumina Human HT12 Version 4 BeadChip array. We identified ER regulated genes affected by KDM3A knockdown and determined that KDM3A is required for ER recruitment to estrogen response elements in the promotors of ER regulated genes. more...

Histone lysine methylation is an important regulator of transcription. Results provide insight into role of KDM3A in ER signaling in breast cancer.

(Submitter supplied) To establish a robust cellular model system for screening genes associated with cell invasion, we over-expressed the oncogenic translocated promoter region (Tpr)-MET proteins in SCC23 cells (SCC23/MET). Using a functional siRNA screen, we identified that the histone demethylase KDM4A played a critical role in the invasive growth and metastasis of SCC mediated by the Oncogenic MET. To investigate the molecular mechanism through which KDM4A inhibit the tumor cell invasion, we knock-down KDM4A in SCC23/MET cell and performed a gene microarray to examine which genes may be regulaged by kDM4A.

(Submitter supplied) We report the high-throughput profilings of HIF1 and histone modifications in human umbilical vein endothelial cells (HUVEC). By obtaining over two billion bases of sequence from chromatin immunoprecipitated DNA, we generated genome-wide chromatin-state maps of HUVEC under normoxia and hypoxia. We find that HIF1binds to not only to transcriptional starting sites but also enhancer regions and that HIF1 binding sites were overlapped with lysine 4 trimethylatio, monomethylation and lysine 27 acetylation . more...

(Submitter supplied) Recent studies have implicated KDM3A, which catalyzes removal of H3K9 methylation, is associated with tumorigenesis. However, the biological role of KDM3A in multiple myeloma, has not been delineated. Here we identify KDM3A-KLF2-IRF4 axis dependence in multiple myeloma. We demonstrate that knockdown of KDM3A leads to apoptosis and significant growth inhibition in myeloma cells. Mechanistically, KDM3A directly regulates myeloma cell survival factor IRF4 expression through H3K9 demethylation at its promoter. more...

(Submitter supplied) Histone demethylation has important roles in regulating gene expression and forms part of the epigenetic memory system that regulates cell fate and identity, by still poorly understood mechanisms. Here we examined the role played by the histone demethylase Kdm3a, which demethylates lysine 9 of histone H3, during cellular differentiation. Using F9 mouse embryonal carcinoma cells as a model for progression through terminal differentiation, we showed that Kdm3a is essential to differentiation into parietal endoderm-like (PE) cells. more...
