H3K9me2 methyltransferase G9a depletion effect on breast cancer cell line

Analysis of MDA-MB231 breast cancer cells depleted for G9a, a methyltransferase that mediates histone H3 lysine-9 di-methylation (H3K9me2). G9a depletion inhibits migratory ability and invasiveness of MDA-MB231 cells. Results provide insight into role of G9a and H3K9me2 in breast cancer progression.

Expression data from knockdown of G9a in MDA-MB231 cells

(Submitter supplied) G9a is an H3K9m2 methyltransferase, which is critical in controlling gene suppression and DNA methylation. We used microarray analysis to identify the target genes that are regulated by G9a in MDA-MB231 cells, in which E-cadherin is silenced.

Gene expression analysis of MDA-MB-231S (sorted for high surface expression of CXCR4) and MDA-Bone-Un (Mouse bone metastasized MDA-MB-231 cells) human basal-like breast cancer cells cultured in 3D-Matrigel was performed.

Effect of knock down of LASP-1 on luminal breast cancer cells (MCF7)

(Submitter supplied) Nuclear LASP-1 has a direct correlation with the overall survival of breast cancer patients. Gene expression analysis of MCF7 human breast cancer cells cultured in 3D-Matrigel was performed. Up regulation of cell junction proteins, extracellular matrix proteins and down regulation of MMP 9 and 2 were observed. This corroborates well with the involvement of LASP-1 in cell migration and chemotaxis.

Expression data from MCF7 breast epithelial cells in normoxic and hypoxic conditions.

(Submitter supplied) G9a is able to silence gene expression in hypoxic condition by increasing histone H3K9me2. We have identified a set of genes that are negatively regulated by G9a in hypoxia-dependent manner. In this dataset, we include the expression data obtained from MCF7 breast epithelial cells that have been transfected with control (WT) or G9a shRNAs (KD) and exposed to either normoxia or hypoxia. These data are used to obtain 829 genes that are differentially expressed in response to hypoxia, and 205 genes that are sentisive to G9a level.

(Submitter supplied) RNA-sequencing analysis of control (shCon) and NSD3-knockdown (shNSD3) MDA-MB-231 cell lines. NSD3 (also known as WHSC1L1), a histone H3 lysine K36methyltransferase, is highly amplificated in several human cancers, including breast carcinomas. Results provide insight into the transcriptional regulation of NSD3 in breast cancer.

G9a-Mediated Methylation of ERα Links the PHF20/MOF Histone Acetyltransferase Complex to Hormonal Gene Expression

(Submitter supplied) The euchromatin histone methyltransferase 2 (EHMT2, aka G9a) methylates histone H3K9 to repress gene expression, but it also acts as a coactivator for some nuclear receptors. The molecular mechanisms underlying this activation remain elusive. Here we show that G9a functions as a bona fide coactivator of the endogenous estrogen receptor α (ERα) in breast cancer cells in a histone methylation-independent manner. more...

G9a histone methyltransferase maintains genomic imprinting in the mouse placenta.

(Submitter supplied) Whereas DNA methylation is essential for genomic imprinting, the importance of histone methylation in the allelic repression of imprinted genes is unclear. ‘Imprinting control regions’ (ICRs), however, are consistently marked by histone H3 K9 methylation on their DNA-methylated allele. In the placenta, the paternal silencing along the Kcnq1 domain on distal chromosome 7 also correlates with the presence of H3-K9 methylation, but imprinted repression at these genes is maintained independently of DNA methylation. more...

Inhibition of EHMT1/2 rescues synaptic and cognitive functions for Alzheimer's disease

(Submitter supplied) Epigenetic dysregulation, which leads to the alteration of gene expression in the brain, is suggested as one of the key pathophysiological bases of aging and neurodegeneration. Here we found that, in the late-stage familial Alzheimer’s disease (FAD) mouse model, repressive histone H3 dimethylation at lysine 9 (H3K9Me2) and euchromatic histone methyltransferases, EHMT1 and EHMT2 (H3K9Me2 catalyzer), were significantly elevated in the prefrontal cortex (PFC) region of post-mortem tissues from human patients with Alzheimer's disease. more...

Gene expression profiling of BIX01294-treated human neuroblastoma cell line BE(2)-C

(Submitter supplied) Increased activation of the serine-glycine biosynthetic pathway is an integral part of cancer metabolism that drives macromolecule synthesis needed for cell proliferation. Whether this pathway is under epigenetic control is unknown. Here we show that the histone H3 lysine 9 (H3K9) methyltransferase G9A is required for maintaining the pathway enzyme genes in an active state marked by H3K9 monomethylation and for the transcriptional activation of this pathway in response to serine deprivation. more...

SPOP mutations derived from prostate cancer establish a DNA hypermethylation epigenome through stabilizing GLP histone methyltransferase [methylation array]

(Submitter supplied) Abnormal DNA methylation is one of the major factors driving oncogenesis and therapy resistance in cancer. The CULLIN3-RBX1 E3 ubiquitin ligase adaptor gene SPOP is the most frequently mutated gene in primary prostate cancers (PCa). SPOP-mutated prostate tumors strikingly associate with strongly elevated levels of genome-wide DNA hypermethylation, although the underlying mechanism remains elusive.We use Illumina Infinium MethylationEPIC BeadChip to depict DNA methylation in control and SPOP F102C stabily expressed 22Rv1 cells. more...
