The HDAC inhibitor Panobinostat (LBH589) exerts in vivo anti-leukaemic activity against in MLL-rearranged Acute Lymphoblastic Leukaemia and involves the RNF20/RNF40/WAC – H2B ubiquitination axis

ABSTRACT: We demonstrate the in vivo efficacy of the histone deacetylase inhibitor Panobinostat (LHB589) against MLL-rearranged ALL using xenograft mouse models of MLL-rearranged ALL cell lines and primary patient cells. Panobinostat monotherapy showed strong anti-leukaemic effects, extending survival and reducing overall disease burden. Comprehensive molecular analyses in vitro showed the anti-leukaemic activity in MLL-rearranged ALL to involve depletion of H2B ubiquitination via suppression of the RNF20/RNF40/WAC E3 ligase complex.

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

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.

mRNA-seq of intestinal epithelial cells isolated from Rnf20 and Rnf40 knockout mice

Project description:Intestinal epithelial cells (IECs) were isolated from the colon of Villin-CreERT2, Rnf20-flox and Rnf40-flox mice two weeks upon the Tamoxifen-induced, intestinal knockout of Rnf20 and Rnf40. RNA was isolated from snap-frozen IECs to perform mRNA-seq.

BMAL1-TTK-H2Bub1 loop deficiency contributes to impaired BM-MSC-mediated bone formation in senile osteoporosis

Project description:We performed multiomic high-throughput sequencing to recapitulated the BMAL1-H2Bub1 loop in mesenchymal stem cells osteogenesis. We used lentiviruses to diminish RNF40 and WAC, which are parts of the obligate complex and monoubiquitinated histone H2B, in MSCs, and analysed the H2Bub1 and PolII CUT&Tag-seq.

The histone H2B ubiquitin ligase RNF20 is required for MLL-rearranged leukemia

Project description:MLL-fusions are potent oncogenes that initiate aggressive forms of acute leukemia. As aberrant transcriptional regulators, MLL-fusion proteins alter gene expression in hematopoietic cells through interactions with the histone H3 lysine 79 (H3K79) methyltransferase DOT1L. Notably, interference with MLL-fusion cofactors like DOT1L is an emerging therapeutic strategy in this disease. Here we identify the histone H2B E3 ubiquitin ligase RNF20 as an additional requirement for MLL-fusion-mediated leukemogenesis. Suppressing the expression of Rnf20 in diverse models of MLL-rearranged leukemia leads to inhibition of cell proliferation; under tissue culture conditions as well as in vivo. Rnf20 knockdown leads to reduced expression of MLL-fusion target genes, including Hoxa9 and Meis1; effects that resemble Dot1l-inhibition. Using ChIP-seq, we found that H2B ubiquitination (H2Bub) is enriched in the body of MLL-fusion target genes, correlating with sites of H3K79 methylation and transcription elongation. Furthermore, we found that Rnf20 is required to maintain local levels of H3K79 di-methylation by Dot1l at Hoxa9 and Meis1. These findings support a model whereby co-transcriptional recruitment of Rnf20 at MLL-fusion target genes leads to amplification of Dot1l-mediated H3K79 methylation, thereby rendering leukemia cells dependent on Rnf20 to maintain their oncogenic transcriptional program.

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
