Sumoylation at Chromatin Governs Coordinated Repression of a Transcriptionnal Program Essential for Cell Growth and Proliferation

ABSTRACT: mRNA profiling of WI38 wild-type or overexpressiong the SUMO E3 ligase PIASy in human primary fibroblasts 24h post-infection. The goal of this study is to analyse transcriptional changes in cells over-expressing the SUMO E3 ligase PIASy and to compare them with ChIPseq data for several histones marks and proteins of the SUMO machinery including PIASy

Despite numerous studies on specific sumoylated transcriptional regulators, the global role of SUMO on chromatin in relation to transcription regulation remains largely unknown. Here, we determined the genome-wide localization of SUMO1 and SUMO2/3, as well as of UBC9 (encoded by UBE2I) and PIASY (encoded by PIAS4), two markers for active sumoylation, along with Pol II and histone marks in proliferating versus senescent human fibroblasts together with gene expression profiling. We found that, whe ...[more]

Genome wide occupancy of SUMO machinery in proliferative and Ras-induced senescent human primary fibroblasts

Project description:Transcription factors represent one of the largest groups of proteins regulated by SUMO, and their modification has generally been correlated with transcriptional repression. However, as most of the studies focus on specific sumoylated transcriptional regulators, the distribution and global role of SUMO on chromatin in relation to transcription regulation remain largely unknown. To investigate this role, we determined the occupancy of SUMO machinery proteins on chromatin by ChIP coupled to sequencing in human primary cells. Examination of 3 histone modifications, Polymerase II, SUMO1, SUMO2, Ubc9 and PIASy in proliferative and Ras-induced senescent fibroblasts.

TRIM28-dependent SUMOylation protects the adult ovary from the male pathway (ChIP-Seq 2)

Project description:We study the role of the protein Trim28 in the maintenance of sexual identity of the adult ovary. With the help of conditional knock out (cKO) of Trim28 using the Nr5a1:Cre, we observed that deletion of the Trim28 gene in granulosa cells of the adult ovary induces their transdifferentiation into Sertoli cells, the supporting cell lineage of the testicular seminiferous tubules. FOXL2 expression has disappeared and follicles were completely remodeled into tubular structures with cells that expressed the Sertoli cell markers SOX8, SOX9 and DMRT1. Histological analysis confirmed the progressive reorganization of ovarian follicles into tubular structures and the and the transdifferentiation of granulosa cells by cells with a Sertoli cell morphology. TRIM28 acts as a SUMO-E3 ligase by interacting with the SUMO-E2 conjugating enzyme UBC9 (encoded by the Ube2i gene) via the Plant homeodomain (PHD), and can self-SUMOylate. To study in vivo the role of TRIM28-dependent SUMOylation, we generated a point mutation in exon 13 of mouse Trim28 within the PHD domain of the TRIM28 protein (C651F) that abrogates its SUMO-E3 ligase activity. We generated Trim28Phd/cKO mice (termed PHD mutant). Like in cKO ovaries, FOXL2 expression was undetectable, whereas we observed expression of the Sertoli cell markers SOX9, SOX8 and DMRT1 within structures organized in pseudo-tubules in PHD ovaries. Our results indicate that maintenance of the female pathway in the adult ovary depends on the E3-SUMO ligase activity of TRIM28.

The E3 SUMO ligase Mms21 controls ribosome biogenesis

Project description:The budding yeast E3 SUMO ligase Mms21, a component of the Smc5-6 complex, regulates sister chromatid cohesion, DNA replication, and DNA repair. We identify a role for Mms21 in ribosome biogenesis. The mms21RINGD mutant exhibits reduced rRNA production, nuclear accumulation of 60S and 40S ribosomal proteins, and elevated Gcn4 translation. Genes involved in ribosome biogenesis and translation are down-regulated in the mms21RINGD mutant. Examining gene expression profile of mms21RINGD mutant compared to wild-type by RNA Seq using Ilumina sequencing

Mutation of ZMYM2 SIMs

Project description:The interaction between SUMO and ZMYM2 is mediated through specific motifs found in ZMYM2 that are called SIMs (SUMO interacting motifs). We found/characterised three SIMs in ZMYM2 and in vitro experiments showed that mutation in these residues prevent the interaction with SUMO. Microarray transcription profiling was done to study the effects of disrupting the multiSUMO binding activity of ZMYM2, assessing the differences in gene expression in cells expressing wild-type or SIM2 mutant version of ZMYM2.
