Histone demethylase KDM4C activates HIF1?/VEGFA signaling through the costimulatory factor STAT3 in NSCLC.

ABSTRACT: Tumor development is accompanied by high hypoxia and a dense network of immature vessels. The hypoxia-inducible factor/vascular endothelial growth factor (HIF/VEGF) signaling pathway is activated in various solid tumors. It is thought that HIF/VEGF signaling activation results from intratumoral hypoxia partly. Multiple studies have reported that VEGF is a common target gene for both transcription factors STAT3 and HIF1. KDM4C has also been reported to function as a co-activation factor for HIF-1?/VEGF signaling activation. In this manuscript. Our results demonstrate that KDM4C promotes NSCLC tumor angiogenesis by transcriptionally activating HIF1?/VEGFA signaling pathway. We also find that STAT3 functions as a costimulatory factor in this process. This pathway opens a potential therapeutic window for the treatment of NSCLC.

Substrate- and cofactor-independent inhibition of histone demethylase KDM4C.

Project description:Inhibition of histone demethylases has within recent years advanced into a new strategy for treating cancer and other diseases. Targeting specific histone demethylases can be challenging, as the active sites of KDM1A-B and KDM4A-D histone demethylases are highly conserved. Most inhibitors developed up-to-date target either the cofactor- or substrate-binding sites of these enzymes, resulting in a lack of selectivity and off-target effects. This study describes the discovery of the first peptide-based inhibitors of KDM4 histone demethylases that do not share the histone peptide sequence or inhibit through substrate competition. Through screening of DNA-encoded peptide libraries against KDM1 and -4 histone demethylases by phage display, two cyclic peptides targeting the histone demethylase KDM4C were identified and developed as inhibitors by amino acid replacement, truncation, and chemical modifications. Hydrogen/deuterium exchange mass spectrometry revealed that the peptide-based inhibitors target KDM4C through substrate-independent interactions located on the surface remote from the active site within less conserved regions of KDM4C. The sites discovered in this study provide a new approach of targeting KDM4C through substrate- and cofactor-independent interactions and may be further explored to develop potent selective inhibitors and biological probes for the KDM4 family.

Histone Demethylase KDM4C Is Required for Ovarian Cancer Stem Cell Maintenance.

Project description:Ovarian cancer is a highly deadly disease, which is often diagnosed at a late stage with metastases. However, most ovarian cancers relapse after surgery combined with platinum-based chemotherapy. Cancer stem cells (CSCs) are stem-like cells that possess high tumorigenic capability and display higher resistant capability against current therapies. However, our knowledge of ovarian CSCs and their molecular mechanism remains sparse. In the current study, we found that KDM4C, a histone demethylase, was required for ovarian cancer stem cell (CSC) maintenance. Depletion of KDM4C significantly reduced the CSC population and sphere formation in vitro. Moreover, we found that KDM4C can regulate the expression of stem cell factor OCT-4 via binding to its promoter. These data indicate that KDM4C is relevant for ovarian CSC maintenance and underscore its importance as a potential therapeutic target.

Histone demethylase KDM4C is a functional dependency in JAK2-mutated neoplasms.

Project description:Mutations of the JAK2 gene are frequent aberrations in the aging hematopoietic system and in myeloid neoplasms. While JAK-inhibitors efficiently reduce hyperinflammation induced by the constitutively active mutated JAK2 kinase, the malignant clone and abundance of mutated cells remains rather unaffected. Here, we sought to assess for genetic vulnerabilities of JAK2-mutated clones. We identified lysine-specific demethylase KDM4C as a selective genetic dependency that persists upon JAK-inhibitor treatment. Genetic inactivation of KDM4C in human and murine JAK2-mutated cells resulted in loss of cell competition and reduced proliferation. These findings led to reduced disease penetrance and improved survival in xenograft models of human JAK2-mutated cells. KDM4C deleted cells showed alterations in target histone residue methylation and target gene expression, resulting in induction of cellular senescence. In summary, these data establish KDM4C as a specific dependency and therapeutic target in JAK2-mutated cells that is essential for oncogenic signaling and prevents induction of senescence.

Histone demethylase PHF8 regulates hypoxia signaling through HIF1α and H3K4me3.

Project description:Hypoxia through transcription factor HIF1α plays a critical role in cancer development. In prostate cancer, HIF1α interplays with androgen receptor (AR) to contribute to the progression of this disease to its lethal form-castration-resistant prostate cancer (CRPC). Hypoxia upregulates several epigenetic factors including histone demethylase KDM3A which is a critical co-factor of HIF1α. However, how histone demethylases regulate hypoxia signaling is not fully understood. Here, we report that histone demethylase PHF8 plays an essential role in hypoxia signaling. Knockdown or knockout of PHF8 by RNAi or CRISPR-Cas9 system reduced the activation of HIF1α and the induction of HIF1α target genes including KDM3A. Mechanistically, PHF8 regulates hypoxia inducible genes mainly through sustaining the level of trimethylated histone 3 lysine 4 (H3K4me3), an active mark in transcriptional regulation. The positive role of PHF8 in hypoxia signaling extended to hypoxia-induced neuroendocrine differentiation (NED), wherein PHF8 cooperates with KDM3A to regulate the expression of NED genes. Moreover, we discovered that the role of PHF8 in hypoxia signaling is associated with the presence of full-length AR in CRPC cells. Collectively, our study identified PHF8 as a novel epigenetic factor in hypoxia signaling, and the underlying regulatory mechanisms likely apply to general cancer development involving HIF1α. Therefore, targeting PHF8 can potentially be a novel therapeutic strategy in cancer therapy.

Histone demethylase KDM4C controls tumorigenesis of glioblastoma by epigenetically regulating p53 and c-Myc.

Project description:Glioblastoma is the most lethal brain tumor and its pathogenesis remains incompletely understood. KDM4C is a histone H3K9 demethylase that contributes to epigenetic regulation of both oncogene and tumor suppressor genes and is often overexpressed in human tumors, including glioblastoma. However, KDM4C's roles in glioblastoma and the underlying molecular mechanisms remain unclear. Here, we show that KDM4C knockdown significantly represses proliferation and tumorigenesis of glioblastoma cells in vitro and in vivo that are rescued by overexpressing wild-type KDM4C but not a catalytic dead mutant. KDM4C protein expression is upregulated in glioblastoma, and its expression correlates with c-Myc expression. KDM4C also binds to the c-Myc promoter and induces c-Myc expression. Importantly, KDM4C suppresses the pro-apoptotic functions of p53 by demethylating p53K372me1, which is pivotal for the stability of chromatin-bound p53. Conversely, depletion or inhibition of KDM4C promotes p53 target gene expression and induces apoptosis in glioblastoma. KDM4C may serve as an oncogene through the dual functions of inactivation of p53 and activation of c-Myc in glioblastoma. Our study demonstrates KDM4C inhibition as a promising therapeutic strategy for targeting glioblastoma.

KDM3A histone demethylase functions as an essential factor for activation of JAK2-STAT3 signaling pathway.

Project description:Janus tyrosine kinase 2 (JAK2)-signal transducer and activator of transcription 3 (STAT3) signaling pathway is essential for modulating cellular development, differentiation, and homeostasis. Thus, dysregulation of JAK2-STAT3 signaling pathway is frequently associated with human malignancies. Here, we provide evidence that lysine-specific demethylase 3A (KDM3A) functions as an essential epigenetic enzyme for the activation of JAK2-STAT3 signaling pathway. KDM3A is tyrosine-phosphorylated by JAK2 in the nucleus and functions as a STAT3-dependent transcriptional coactivator. JAK2-KDM3A signaling cascade induced by IL-6 leads to alteration of histone H3K9 methylation as a predominant epigenetic event, thereby providing the functional and mechanistic link between activation of JAK2-STAT3 signaling pathway and its epigenetic control. Together, our findings demonstrate that inhibition of KDM3A phosphorylation could be a potent therapeutic strategy to control oncogenic effect of JAK2-STAT3 signaling pathway.

Novel germline variant in the histone demethylase and transcription regulator KDM4C induces a multi-cancer phenotype.

Project description:BackgroundGenes involved in epigenetic regulation are central for chromatin structure and gene expression. Specific mutations in these might promote carcinogenesis in several tissue types.MethodsWe used exome, whole-genome and Sanger sequencing to detect rare variants shared by seven affected individuals in a striking early-onset multi-cancer family. The only variant that segregated with malignancy resided in a histone demethylase KDM4C. Consequently, we went on to study the epigenetic landscape of the mutation carriers with ATAC, ChIP (chromatin immunoprecipitation) and RNA-sequencing from lymphoblastoid cell lines to identify possible pathogenic effects.ResultsA novel variant in KDM4C, encoding a H3K9me3 histone demethylase and transcription regulator, was found to segregate with malignancy in the family. Based on Roadmap Epigenomics Project data, differentially accessible chromatin regions between the variant carriers and controls enrich to normally H3K9me3-marked chromatin. We could not detect a difference in global H3K9 trimethylation levels. However, carriers of the variant seemed to have more trimethylated H3K9 at transcription start sites. Pathway analyses of ChIP-seq and differential gene expression data suggested that genes regulated through KDM4C interaction partner EZH2 and its interaction partner PLZF are aberrantly expressed in mutation carriers.ConclusionsThe apparent dysregulation of H3K9 trimethylation and KDM4C-associated genes in lymphoblastoid cells supports the hypothesis that the KDM4C variant is causative of the multi-cancer susceptibility in the family. As the variant is ultrarare, located in the conserved catalytic JmjC domain and predicted pathogenic by the majority of available in silico tools, further studies on the role of KDM4C in cancer predisposition are warranted.

Histone demethylase KDM4D promotes gastrointestinal stromal tumor progression through HIF1β/VEGFA signalling.

Project description:BackgroundGastrointestinal stromal tumour (GIST) is the most common soft tissue sarcoma. The identification of the molecular mechanisms regulating GIST progression is vital for its treatment and prevention. Increasing reports have demonstrated that epigenetic alterations play critical roles in GIST development. However, the role of the histone demethylase KDM4D in GIST progression is poorly understood.MethodsIn clinically matched GIST tissues, KDM4D protein levels were measured by Western blot and immunohistochemical (IHC) staining. KDM4D mRNA levels were examined by quantitative real-time PCR (qRT-PCR). Bioinformatics analysis was used to examine KDM4D expression. The biological effects of KDM4D were investigated in vitro using CCK-8, BrdU/PI, wound healing, colony formation, tube formation and Transwell assays and in vivo using a xenograft mice model. Luciferase assays were used to assess regulation of HIF1β gene promoter activity by KDM4D. ChIP assays were performed to assess KDM4D, H3K36me3 and H3K9me3 occupancy on the HIF1β gene promoter.ResultsWe observed a significant upregulation of KDM4D in GIST tissue compared with matched normal tissue and further explored the oncogenic function of KDM4D both in vitro and in vivo. Furthermore, we demonstrated that KDM4D directly interacted with the HIF1β gene promoter and regulated its activity, promoting tumour angiogenesis and GIST progression both in vitro and in vivo. Finally, we demonstrated that KDM4D transcriptionally activates HIF1β expression via H3K9me3 and H3K36me3 demethylation at the promoter region.ConclusionsOur findings reveal the important roles of the KDM4D/HIF1β/VEGFA signalling pathway in GIST progression, and this pathway may act as a potential therapeutic target for GIST patients.

Histone demethylase PHF2 activates CREB and promotes memory consolidation.

Project description:Long-term memory formation is attributed to experience-dependent gene expression. Dynamic changes in histone methylation are essential for the epigenetic regulation of memory consolidation-related genes. Here, we demonstrate that the plant homeodomain finger protein 2 (PHF2) histone demethylase is upregulated in the mouse hippocampus during the experience phase and plays an essential role in memory formation. PHF2 promotes the expression of memory-related genes by epigenetically reinforcing the TrkB-CREB signaling pathway. In behavioral tests, memory formation is enhanced by transgenic overexpression of PHF2 in mice, but is impaired by silencing PHF2 in the hippocampus. Electrophysiological studies reveal that PHF2 elevates field excitatory postsynaptic potential (fEPSP) and NMDA receptor-mediated evoked excitatory postsynaptic current (EPSC) in CA1 pyramidal neurons, suggesting that PHF2 promotes long-term potentiation. This study provides insight into the epigenetic regulation of learning and memory formation, which advances our knowledge to improve memory in patients with degenerative brain diseases.

Histone Demethylase KDM4C Stimulates the Proliferation of Prostate Cancer Cells via Activation of AKT and c-Myc.

Project description:Our three-dimensional organotypic culture revealed that human histone demethylase (KDM) 4C, a histone lysine demethylase, hindered the acini morphogenesis of RWPE-1 prostate cells, suggesting its potential oncogenic role. Knockdown (KD) of KDM4C suppressed cell proliferation, soft agar colony formation, and androgen receptor (AR) transcriptional activity in PCa cells as well as reduced tumor growth of human PCa cells in zebrafish xenotransplantation assay. Micro-Western array (MWA) analysis indicated that KD of KDM4C protein decreased the phosphorylation of AKT, c-Myc, AR, mTOR, PDK1, phospho-PDK1 S241, KDM8, and proteins involved in cell cycle regulators, while it increased the expression of PTEN. Fluorescent microscopy revealed that KDM4C co-localized with AR and c-Myc in the nuclei of PCa cells. Overexpression of either AKT or c-Myc rescued the suppressive effect of KDM4C KD on PCa cell proliferation. Echoing the above findings, the mRNA and protein expression of KDM4C was higher in human prostate tumor tissues as compared to adjacent normal prostate tissues, and higher KDM4C protein expression in prostate tumors correlated to higher protein expression level of AKT and c-Myc. In conclusion, KDM4C promotes the proliferation of PCa cells via activation of c-Myc and AKT.
