Project description:The Jumonji domaining-containing protein JMJD6 is a 2-oxoglutarate dependent dioxygenase that has been implicated in a broad range of biological functions. Cellular studies have implicated the enzyme in chromatin biology, transcription, DNA repair, mRNA splicing and co-transcriptional processing. Although not all studies agree, JMJD6 has been reported to catalyse both hydroxylation of lysine residues and demethylation of arginine residues. However, despite extensive study and the indirect implication of JMJD6 catalysis in many cellular processes, direct assignment of JMJD6 catalytic substrates has been limited. Examination of a site of reported prolyl hydroxylation within a lysine-rich region of the bromodomain protein BRD4 led us to conclude that hydroxylation was in fact on lysine and catalysed by Jmjd6. This prompted a wider search for JMJD6-catalysed protein modifications deploying mass spectrometric methods designed to identify novel substrate associations and facilitate analysis of lysine-rich regions by LC-MSMS. Using derivatization of lysine with propionic anhydride to improve the analysis of tryptic peptides and a pharmacological inhibitor of JMJD6 to stabilise enzyme/substrate associations, we report over 100 sites of JMJD6-catalysed lysyl hydroxylation on 48 protein substrates including 19 sites of hydroxylation on BRD4. Most hydroxylations were within lysine-rich regions that are predicted to be unstructured; in some multiple modifications were observed on adjacent lysine residues. Almost all of the JMJD6 substrates defined in this study have been associated with membraneless organelle formation. Taken together with findings implicating lysine-rich regions in subcellular partitioning by liquid-liquid phase separation, our findings raise the possibility that JMJD6 may play a role in regulating such processes in response to stresses, including hypoxia. Note, this dataset corresponds to Figure 3 of the published manuscript; which employs a substrate-trapping methodology to identify novel substrates of JMJD6 by label free DIA approach.

Project description:The goal of the experiment was to demonstrate if the overexpression of human-Prune-1 in Triple Negative breast cancer cells induces M2-polarization of macrophages in vitro. For this purpose, murine primary cells from breast tumor developed by Genetically Engineered Mouse Models (GEMMs) of TNBC (i.e., MMTV-Wnt1) and metastatic TNBC overexpressing both human Prune-1 and Wnt1 in mammary gland (i.e., MMTV-Prune-1/Wnt1) were obtained. Conditioned media were collected from these primary cells (1x106 cells) after 24 hours. Murine macrophages (J774A.1 and Raw264.7; 1x106) were starved for six hours and then grown for 48 hours in those conditioned media collected from MMTV-Wnt1 and MMTV-Prune-1/Wnt1 cells. Untreated macrophages were used as negative control for the experiment.

Project description:By survival analysis of breast cancer patients, JMJD6 was found to be significantly associated with poor prognosis. Over-expression and knock-down of JMJD6 in breast cancer cell lines suggested a role in proliferation. In order to study the transcriptional events that occur following JMJD6 expression changes, siRNA-mediated knock-down of JMJD6 was performed in MCF-7 and MDA-MB231 and stable over-expression of JMJD6 was performed in MCF-7. There are 2 different siRNA-mediated knock-downs of JMJD6 with 2 biological replicates in MCF-7 and MDA-MB231; 3 clones of JMJD6 over-expression with 3 biological replicates in MCF-7. The control for the knock-downs is scrambled siRNA-treated MCF-7 and MDA-MB231 and the control for JMJD6 over-expression is empty vector over-expression in MCF-7.

Project description:Clear cell renal cell carcinoma (ccRCC) represents a lethal disease and classically resistant to cytotoxic chemotherapy, highlighting the importance of identifying new therapeutic vulnerabilities. We performed a functional siRNA screening for all 2-oxoglutarate (2-OG)-dependent enzymes in ccRCC using 3-D soft agar colony formation assay, and combined with TCGA data, we identified Jumonji domain-containing 6 (JMJD6) as an essential gene for ccRCC tumorigenesis. Downregulation of JMJD6 abolished ccRCC colony formation in vitro and inhibited orthotopic tumor growth in vivo. Integrated analyses of ChIP-seq and RNA-seq identified that JMJD6 can transcriptionally regulate the expression of diacylglycerol O-acyltransferase 1 (DGAT1) by co-occupying the target gene promoter with H3K4me3. Downregulation of JMJD6 caused decreased expression of DGAT1 at both mRNA and protein level. Inhibition or depletion of DGAT1 induced decreased cell growth in vitro or inhibited tumor growth in vivo. Mechanistically, decreased DGAT1 caused decreased LD formation in ccRCC, while restoration of JMJD6 expression can restore DGAT1 level, and LD formation as well as cell growth. In summary, JMJD6 is essential for ccRCC lipid storage and tumorigenesis through a DGAT1-dependent signaling. Therefore, the JMJD6-DGAT1 axis serves as a potential therapeutic avenue for ccRCC.

Project description:Chromosome 17q gain occurs frequently in MYC-driven tumors including high-risk neuroblastoma. However, the biological consequences of this genetic event remain elusive. Here we show that JMJD6, frequently amplified at the chromosome 17q25 locus, is one of the essential genes to neuroblastoma cells that are engaged in pathways of mitochondrial metabolism, RNA processing and protein homeostasis. JMJD6 cooperates with MYC in cellular transformation and promotes cancer cell proliferation and tumor growth. Mechanistically, JMJD6 physically interacts with RNA-processing machinery to regulate the alternative splicing and protein synthesis. Notably, JMJD6 controls the alternative splicing of glutaminase (GLS), kidney-type glutaminase (KGA) and glutaminase C (GAC), a rate-limiting enzyme of glutaminolysis, and, consequently, the central carbon metabolism in neuroblastoma. Our findings indicate that JMJD6 coordinates with MYC in tumorigenesis by regulating cancer-promoting metabolic programs through an alternative pre-mRNA splicing mechanism.
