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.

Complimentary vertebrate Wac models exhibit phenotypes relevant to DeSanto-Shinawi Syndrome

Project description:Monogenic syndromes are associated with neurodevelopmental changes that result in cognitive impairments, neurobehavioral phenotypes including autism and attention deficit hyperactivity disorder (ADHD), and seizures. Limited studies and resources are available to make meaningful headway into the underlying molecular mechanisms that result in these symptoms. One such example is DeSanto-Shinawi Syndrome (DESSH), a rare disorder caused primarily by pathogenic variants in the WAC gene. Individuals with DESSH syndrome exhibit a recognizable craniofacial gestalt, developmental delay/intellectual disability, neurobehavioral symptoms that include autism, ADHD, behavioral difficulties and seizures. However, no thorough studies from a mammalian model exist to understand how these changes occur. To overcome this, we developed both murine and zebrafish Wac deletion mutants and studied whether their phenotypes recapitulate those described in individuals with DESSH syndrome. We show that the two Wac models exhibit craniofacial and behavioral changes, reminiscent of abnormalities found in DESSH syndrome. In addition, each model revealed impacts to GABAergic neurons and further studies showed that the mouse mutants are susceptible to seizures. These studies begin to uncover some biological underpinnings of DESSH syndrome and elucidate the biology of Wac, with advantages in each model.

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.

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