Effects of Nickel Treatment on H3K4 Trimethylation and Gene Expression
Occupational exposure to nickel compounds has been associated with lung and nasal cancers. We have previously shown that exposure of the human lung adenocarcinoma A549 cells to NiCl(2) for 24 hr significantly increased global levels of trimethylated H3K4 (H3K4me3), a transcriptional activating mark that maps to the promoters of transcribed genes. To further understand the potential epigenetic m...
متن کاملCfp1 integrates both CpG content and gene activity for accurate H3K4me3 deposition in embryonic stem cells.
Trimethylation of histone H3 Lys 4 (H3K4me3) is a mark of active and poised promoters. The Set1 complex is responsible for most somatic H3K4me3 and contains the conserved subunit CxxC finger protein 1 (Cfp1), which binds to unmethylated CpGs and links H3K4me3 with CpG islands (CGIs). Here we report that Cfp1 plays unanticipated roles in organizing genome-wide H3K4me3 in embryonic stem cells. Cf...
متن کاملComparing the Expression Levels of Alkaline Phosphatase, Gfra1, Lin28, and Sall4 Genes in Embryonic Stem Cells, Spermatogonial Stem Cells, and Embryonic Stem-Like Cells in Mice
Background and purpose: Spermatogenesis is a well-organized process that is influenced by a variety of factors. Alkaline phosphatase, and Gfra1, Lin28, and Sall4 genes are among the key players in this interconnected process. This study aimed to investigate the expression levels of Gfra1, Lin28, and Sall4 genes in embryonic, spermatogonial, and embryonic stem-like (ES-like) cells in mice. Mate...
متن کاملMesenchymal Stem/Stromal-Like Cells from Diploid and Triploid Human Embryonic Stem Cells Display Different Gene Expression Profiles
Background: Human ESCs-MSCs open a new insight into future cell therapy applications, due to their unique characteristics, including immunomodulatory features, proliferation, and differentiation. Methods: Herein, hESCs-MSCs were characterized by IF technique with CD105 and FIBRONECTIN as markers and FIBRONECTIN, VIMENTIN, CD10, CD105, and CD14 genes using RT-PCR technique. FACS was performed fo...
متن کاملLid2 Is Required for Coordinating H3K4 and H3K9 Methylation of Heterochromatin and Euchromatin
In most eukaryotes, histone methylation patterns regulate chromatin architecture and function: methylation of histone H3 lysine-9 (H3K9) demarcates heterochromatin, whereas H3K4 methylation demarcates euchromatin. We show here that the S. pombe JmjC-domain protein Lid2 is a trimethyl H3K4 demethylase responsible for H3K4 hypomethylation in heterochromatin. Lid2 interacts with the histone lysine...
