KDM4A depletion by siRNA in HEK293T cells

ABSTRACT: The goal of this study was to determine genes affected by depletion of KDM4A in HEK293T cells This data was used in Van Rechem et. al. Cancer Discovery 2014 to demonstrate that depletion of KDM4A did not alter expression of genese associated with translation. The experiment uses two different shRNA constructs; shKDM4A.2 in a pSuper backbone and shKDM4A.6 in a pLKO backbone. A corresponding empty vector control was conducted for each backbone. Each shRNA was compared to its own control.

Expression profiling of myeloid leukemia cell treated with vibsanine A, PMA and ATRA

Project description:All-trans retinoic acid (ATRA)-based differentiation therapy has achieved success with the treatment of acute promyelocytic leukemia (APL), a unique subtype of acute myeloid leukemia (AML). However, other subtypes of AML display resistance to ATRA-based treatment. Here, we demonstrate that a novel natural vibsane-type diterpenoid vibsanine A promotes the differentiation of myeloid leukemia cell lines and primary AML blasts. To reveal how vibsanine A function on promoting myeloid leukemia cell differentiation, we analyzed and compared the gene expression profiles in myeloid leukemia HL-60 cells treated with vibsanine A, PMA, and ATRA. HL-60 cells were treated with vibsanine A, PMA and ATRA for 6 hours or longer up to 24 hours. Gene expression profiling was conducted

Efficient Elimination of Acute Myeloid Leukaemia Cells through Inhibition of KDM4A

Project description:We previously identified an essential role for the H3K9me3 histone demethylase, KDM4A, in maintaining AML cell survival, with genetic depletion by shRNA of KDM4A inducing leukaemic cell death with little effect on normal haematopoiesis. We hypothesised KDM4A inhibition may represent a novel and effective strategy to treat AML. To address this, we provided proof-of-principle for the use of KDM4 inhibitors (KDM4Ai) and fully characterised their functional potential in AML cells and identified the epigenetic mechanisms underpinning the essential role of KDM4A activity in THP-1 cells using both ChIP-seq and RNA-seq, delineating and functionally validating the epigenomic network regulated by KDM4A, showing that selective loss of KDM4A is sufficient to induce apoptosis in a broad spectrum of human AML cells. This detrimental phenotype results from a global accumulation of H3K9me3 and H3K27me3 at KDM4A targeted genomic loci thereby causing down-regulation of a KDM4A-PAF1 controlled transcriptional program essential for leukemogenesis, distinct from that of KDM4C.

KDM4A regulated gene expression in human prostate cancer LNCaP cell

Project description:Histone lysine demethylase KDM4A is overexpressed in prostate cancer and plays a crucial role in tumor growth and survival. To understand the mechanisms underlying KDM4A-depedent cell growth and survival, microarray analysis was performed in LNCaP cells transduced with control or KDM4A specific-knockdown construct. The role of KDM4A in prostate carcinogenesis involves activation of E2F1 and androgen receptor transcriptional profiles. LNCaP cells were transduced by lentivirus carrying control pLKO.1 (empty vector) or shKDM4A construct (KDM4A-specific shRNA) for three days, followed by RNA extraction. Affymetrix GeneChip Human Genome U133 Plus 2.0 Arrays were used for microarray analysis.

KDM4A regulated genes in human squamous carcinoma cells

Project description: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. We generated two stable cell lines. one was infected with virus containing scramble and another infected with virus infected with virus containing KDM4A shRNA. Total RNA were extracted from these two cell lines and subject to microarray.

2.5 dpc Uterus Chip-Seq of Kdm4a mice

Project description:Purpose: ChipSeq allows us to identify binding sites of target proteins of interest in the genome, helping create a global profile for the same. Kdm4a is a H3K9me3 histone demethylase that acts to prevent spurious accumulation of this repressive mark at H3K4me3 positive transcription start sites. To complement transcriptome data from Kdm4a mice, we performed Chip-Seq on 2.5dpc mouse uterus of 8-10 week old littermate control and Kdm4a knockout mice for Kdm4a, H3K9me3 and H3K4me3. This would help us check which of the target genes with changed gene expression was due to the direct change in histone lanscape in absence of Kdm4a.

Kdm4a is an activity downregulated barrier to generate engrams for memory separation

Project description:Memory engrams are a subset of learning activated neurons critical for memory recall, consolidation, extinction and separation. While the transcriptional profile of engrams after learning suggests profound neural changes underlying plasticity and memory formation, little is known about how memory engrams are selected and allocated. As epigenetic factors suppress memory formation, we developed a CRISPR screening in the hippocampus to search for factors controlling engram formation. We identified histone lysine-specific demethylase 4a (Kdm4a) as a novel regulator for engram formation. Kdm4a is downregulated after neural activation and controls the volume of mossy fiber boutons. Mechanistically, Kdm4a anchors to the exonic region of Trpm7 gene loci, causing the stalling of nascent RNAs and allowing burst transcription of Trpm7 upon the dismissal of Kdm4a. Furthermore, the YTH domain containing protein 2 (Ythdc2) recruits Kdm4a to the Trpm7 gene and stabilizes nascent RNAs. Reducing the expression of Kdm4a in the hippocampus via genetic manipulation or artificial neural activation facilitated the ability of pattern separation in rodents. Our work indicates that Kdm4a is a negative regulator of engram formation and suggests a priming state to generate a separate memory.
