RNA-seq data of esophageal cancer cell Kyse510 after inhibition or silencing of LSD1 and G9a

Project description:The goals of this study are to compare transcriptome profiling (mRNA level) and signaling pathways between the control and ablating LSD1, the control and ablating G9a, the control and co-ablating LSD1 and G9a. We found pathways in apoptosis, endoplasmic reticulum stress and unfolded protein response were obviously changed in these groups, which are important for esophageal cancer therapy.

RNA-seq analysis in esophageal squamous cell carcinoma (ESCC) cell line KYSE510

Project description:We report the application of RNA-seq analysis in three kinds of KYSE510 cell lines. One group of cells was transfected with scremble RNA as control and the other two groups of cells were transfected with TCONS_02256997 shRNAs individually to knockdown transcript TCONS_02256997. We did RNA-seq aim to explore the potential target fectors that TCONS_02256997 might effect to and try to explain the mechanism it caused tumor progression.

The Histone H3 Lysine 9 Methyltransferases G9a and GLP Regulate Polycomb Repressive Complex 2-Mediated Gene Silencing [Affymetrix]

Project description:G9a/GLP and Polycomb Repressive Complex 2 (PRC2) are two major epigenetic silencing machineries, which in particular methylate histone H3 on lysines 9 and 27 (H3K9 and H3K27), respectively. Although evidence of a crosstalk between H3K9 and H3K27 methylations has started to emerge, their actual interplay remains elusive. Here, we show that PRC2 and G9a/GLP interact physically and functionally. Moreover, combining different genome-wide approaches, we demonstrate that Ezh2 and G9a/GLP share an important number of common genomic targets, encoding developmental and neuronal regulators. Furthermore, we show that G9a enzymatic activity modulates PRC2 genomic recruitment to a subset of its target genes. Taken together, our findings demonstrate an unanticipated interplay between two main histone lysine methylation mechanisms, which cooperate to maintain silencing of a subset of developmental genes. Microarray has been perform in triplicate on total extract RNA from mES cell (TT2 : Wildtype and KOs G9a-/-, GLP-/-, G9a-/- and GLP-/-)

The Histone H3 Lysine 9 Methyltransferases G9a and GLP Regulate Polycomb Repressive Complex 2-Mediated Gene Silencing [ChIP-Seq]

Taken together, our findings demonstrate an unanticipated interplay between two main histone lysine methylation mechanisms, which cooperate to maintain silencing of a subset of developmental genes. ChIP-seq has been performed for G9a and Ezh2 in wild type TT2 mES cells or in mES cells lacking both G9a and GLP (G9a-/-GLP-/-). As a control, input DNA was saved before immunoprecipitation. Note that the two inputs (Input_TT2_0 and Input_TT2_1) have been combined and used as control for Ezh2 and G9a ChIP-seq.

G9a plays distinct roles in maintaining DNA methylation, retrotransposon silencing and chromatin looping

Project description:G9a is a lysine methyltransferase that regulates epigenetic modifications, transcription and genome organization. However, whether these properties are dependent on one another or represent distinct functions of G9a remains unclear. In this study, we observe widespread DNA methylation loss in G9a depleted and catalytic mutant embryonic stem cells. Furthermore, we define how G9a regulates chromatin accessibility, epigenetic modifications and transcriptional silencing in both catalytic dependent and independent manners. Reactivated retrotransposons provide alternative promoters and splice sites leading to upregulation of neighboring genes and production of chimeric transcripts. Moreover, while topologically associated domains and compartments A/B definitions are largely unaffected, the loss of G9a leads to altered chromatin states, aberrant CTCF and cohesin binding, and differential chromatin looping especially at retrotransposons. Taken together, our findings reveal how G9a regulates the epigenome, transcriptome and higher-order chromatin structures in distinct mechanisms.

Transcriptomes Analysis of LHX2-knockdown in KYSE30 and KYSE510 cells

Project description:Purpose: To fully realize the potential molecular mechanism that LHX2 promotes ESCC progression Methods: Total RNA of LHX2-knockdown KYSE30/KYSE510 and control cells was extracted with TRIzol Reagent. RNA libraries were constructed using an Illumina TruSeq RNA Sample Preparation kit according to the manufacturer’s protocol. A total of 150 base paired-end reads were sequenced using the Novaseq 6000 S4 platform. Results: We identified 26008 transcripts in KYSE30 control and KYSE30 LHX2-knockdown cells ,and 25561 transcripts in KYSE510 control and KYSE510 LHX2-knockdown cells. Conclusions: Our study represents the analysis of LHX2-knockdown ESCC cells, generated by RNA-seq.

Identification of proteins stably associated with G9a/GLP (EHMT2/EHMT1) complex of histone methyltransferases

Project description:G9a (EHMT2) and the G9a-like protein GLP (EHMT1) form a stable G9a/GLP heterodimer in embryonic stem cells and function cooperatively to establish and maintain the abundant repressive H3K9me2 modification, in addition to modifying several non-histone proteins. The G9a-dependent H3K9me2 is implicated in lineage-specific gene silencing and covers large chromosomal domains. While the mechanism of H3K9me2maintenance by G9a/GLP is known, how new patterns of this modification are established is not well understood. With this in mind, we used FLAG affinity purification of G9a under two different stringency conditions (150 and 300 mM NaCl) coupled with mass spectrometry to identify proteins stably associated with G9a/GLP, which could serve as potential recruiters of the complex to unmodified chromatin.
