Role of Rnf40-dependent histone monoubiquitination in peripheral nervous system myelination [RNA-Seq]

Project description:To address the role of monoubiquitination of histone H2B at lysine 120 (H2Bub1), we inactivated the responsible E3 ligase by deleting Rnf40 in developing Schwann cells. Rnf40 becomes important for proper Schwann cell development shortly before and during differentiation. Its absence in Schwann cells leads to a peripheral neuropathy. RNA-Seq studies were performed on sciatic nerves from control mice and mice with a Schwann cell-specific deletion of Rnf40 to analyze changes in gene expression. These revealed substantial changes in the expression of genes associated with myelination, lipid metabolism and cell adhesion.

Rnf40 becomes important for proper Schwann cell development shortly before and during differentiation. Its absence in Schwann cells leads to a peripheral neuropathy. ChIP-Seq studies with H2Bub1-specific antibodies were performed on sciatic nerves from control mice and mice with a Schwann cell-specific deletion of Rnf40 to detect alterations in genomic H2Bub1 occupancy. These correlated with changes in the expression of genes associated with myelination and lipid metabolism.

Regulation of gene expression by WAC/RNF20/RNF40 in HEK293A cells

2015-12-17 | GSE66475 | GEO

Regulation of gene expression by WAC/RNF20/RNF40 in HEK293A cells

Project description:WAC is a known positive regulator of (macro)autophagy. WAC also forms a complex with RNF20/RNF40 to promote H2B monoubiquitination and hence to affect transcriptional regulation. This study addresses whether the WAC/RNF20/RNF40 complex regulates autophagy through effects on gene expression. WAC, RNF20 and RNF40 were knocked-down using pools of siRNAs in HEK293A cells. Each knockdown was in triplicate and the control was RISCfree siRNA. mRNA expression profiles were investigated using an Illumina HT12v4 Bead Array.

RNF40 exerts stage-dependent functions in differentiating osteoblasts and is essential for bone cell crosstalk [ChIP-seq]

Project description:In this study, we focused on elucidating the role of Ring Finger Protein 40 (RNF40) in bone development by using a conditional knockout mouse approach during different stages of osteoblast (OB) differentiation and maturation. RNF40 forms an obligate E3 ubiquitin ligase complex together with RNF20 and mediates the monoubiquitination of lysine 120 of histone H2B (H2BK120ub1). We provide evidence that RNF40 regulates OB differentiation in a stage-dependent manner. Additionally, we show that RNF40 is required for bone cell crosstalk whereby loss of RNF40 leads to a reduction in osteoclast numbers and function through modulation of vitamin D receptor (VDR)-induced Rankl expression in OBs. Taken together, these data imply an important role of RNF40-mediated H2Bub1 in bone formation and remodeling and provide a basis for further investigation of its anti-resorptive potential for the treatment of conditions such as osteoporosis or cancer-associated osteolysis. In this study we show that RNF40 is required in earlier stages of osteoblast differentiation and is involved in bone cell crosstalk by regulating vitamin D induced Rankl expression
