Project description:To investigate the effect of HSATIII lncRNA on m6A modification, we performed m6A-RIP(RNA immuno precipitation) RNA-seq from heat shock-exposed HeLa cells upon HSATIII knockdown.

ZMYND8 reads the dual histone mark H3K4me1-H3K14ac to antagonize the expression of metastasis-linked genes

Project description:Histone acetylation, including acetylated H3K14 (H3K14ac), is generally linked to gene activation. Monomethylated histone H3 lysine 4 (H3K4me1), together with other gene-activating marks, denotes active genes. In contrast to usual gene-activating functions of H3K14ac and H3K4me1, we here show that the dual histone modification mark H3K4me1-H3K14ac is recognized by ZMYND8 (also called RACK7) and functions to counteract gene expression. We identified ZMYND8 as a transcriptional corepressor of the H3K4 demethylase JARID1D. ZMYND8 antagonizes the expression of metastasis-linked genes, and its knockdown increases the cellular invasiveness in vitro and in vivo. The plant homeodomain (PHD) and Bromodomain cassette in ZMYND8 mediates the combinatorial recognition of H3K4me1-H3K14ac and H3K4me0-H3K14ac by ZMYND8. These findings uncover an unexpected role for the signature H3K4me1-H3K14ac in attenuating gene expression and reveal a previously unknown metastasis-suppressive epigenetic mechanism in which ZMYND8's PHD-Bromo cassette couples H3K4me1-H3K14ac with repression of metastasis-linked genes. i) ChIP-Seq data of ZMYND8, JARID1D, H3K4me1, H3K14ac, H3K4me3, and H3K27me3 in normal DU145 cells. ii) ChIP-Seq data of H3K4me1 and H3K4me3 in shLuciferase-, shJARID1D-, or shZMYND8-treated DU145 cells. iii) RNA-Seq data in shLuciferase-, shJARID1D-, or shZMYND8-treated DU145 cells.

Expression data from Dicer and Ago2-knockdown HeLa cells

Project description:Dicer and Argonaute2 (Ago2) gene is involving in microRNA (miRNA) maturation. Knockdown of these genes has great impact on miRNA expression profiles. We used microarrays to detail the miRNA expression profiles in Dicer- and Ago2-knockdown HeLa cells and demonstarted that the significant difference between Ago2-knockdown and Dicer- and Ago2-co-knockdown HeLa cells were not found.
