Novel MST1 inhibitor accelerates murine liver regeneration following partial hepatectomy with improved survival in models of steatohepatitis

ABSTRACT: Disrupted hepatocyte regeneration following surgical resection remains a clinical problem with few therapeutic options. The current treatment paradigm relies on supportive therapy until homeostasis can be achieved. Pharmacologic acceleration of regeneration may provide an alternative therapeutic avenue. Therefore, we aimed to generate a small molecule inhibitor that could accelerate liver regeneration in both normal and diseased murine preclinical models. mCLC846 demonstrated on target inhibition of MST1 and reduced EGFR inhibition which resulted in Yes-associated protein (YAP) activation. Oral delivery of mCLC846 perioperatively resulted in accelerated liver regeneration and improved survival in diet induced NASH models. Transcriptional analysis suggested that mCLC846 enhanced the normal regenerative pathways induced following liver resection. Overall, pharmacological acceleration of liver regeneration with mCLC846 was feasible, had an acceptable therapeutic index, and provided survival benefit in models of diet induced non-alcoholic steatohepatitis.

Gene expression profile of mouse liver cancer (Sav1 and Mst1/2 Knockout models)

Project description:Hippo pathway is evolutionarily well conserved. All core components of the pathway identified to date have one or more mammalian orthologs, including MST1/2 (Hippo), SAV1 (Salvador, also known as WW45), LATS1/2 (Warts), MOB1 (Mats), YAP1 and its paralog WWTR1 (also known as TAZ) (Yorkie), and TEAD1/2/3/4 (Scalloped). Ectopic over-expression of YAP1 in mouse liver led to develop hepatocellular carcinoma (HCC). HCC is the third most common cause of cancer-related death in the world, and accounts for an estimated 600,000 deaths annually. Lack of molecular classification and clinical heterogeneity of this malignant disease hampered the development of standardized treatment. To investigate roles of Hippo pathway in liver carcinogenesis, we generated liver-specific Mst1/2 -/- and Sav1 -/- mouse models and collected gene expression data from them. Our study provided new understanding on molecular characteristics of HCC. Sav1 and Mst1/2 Knockout models

Gene profiling of heart atria in PI3K and Mst1 mouse models

Project description:We used microarrays to detail genome-wide gene expression underlying cardiac myocyte pathologies and identified candidate genes and specific pathways affecting cardiac myopathies Keywords: transgenics, cardiac disease analysis Mouse heart atria were dissected for RNA extraction and hybridisation on Affymetrix microarrays. We sought to profile gene expression from the transgenic mouse models for non-transgenics (Ntg), dnPI3K (dominant negative for phosphoinositide 3-kinase), Mst1 (mammalian sterile 20-like kinase 1) and dnPI3K-Mst1 (double mutant) mouse models with a combined background of C57BL/6/FVB/N inbred strains. Pathological insults on cardiac myocytes are investigated

Leukotriene B4 receptor 1 antagonist in combination with kinase MST1/2 inhibitor has potential for treatment of myocardial infarction

Project description:Timely inhibition of inflammation and initiation of resolution are important for the repair of injured tissues. Pharmacological inhibition of mammalian STE20-like protein kinase 1/2 (MST1/2) with XMU-MP-1 might augment tissue regeneration and repair by suppressing apoptosis and increasing cell proliferation. However, MST1 has anti-inflammatory activity, inhibition of which may result in therapy failure. Here, we identified an approach with the potential to overcome this limitation by protecting against cardiac inflammation resulting from inhibition of MST1 in macrophages. We found exacerbation of cardiac dysfunction in LysMCre-mediated Mst1/2-deficient mice after myocardial infarction (MI). This effect was attributed to a shift of macrophage subtypes from those expressing Cxcl2 and Cd163 toward those with Ccl2 and Ccl4 expression. Mass spectrometry identified leukotriene B4 (LTB4) as the lipid mediator that was upregulated in the absence of MST1. We found that MST1 phosphorylated 5-lipoxygenase (5-LOX) at its T218 residue, disrupting the interaction between 5-LOX and 5-LOX-activating protein, and resulting in reduction of LTB4 production. By contrast, a 5-LOXT218A variant showed no response to MST1. Moreover, treatment of peritoneal macrophages with LTB4 or with medium conditioned by Mst1-deficient macrophages resulted in high Ccl2 and Ccl4 expression and low Cxcl2 and Cd163 expression, except when the cells were co-treated with the LTB4 receptor 1 (BLT1) antagonist CP105696. Furthermore, CP105696 ameliorated cardiac dysfunction in LysMCre-mediated Mst1/2-deficient mice and enhanced cardiac repair in wild-type mice treated with XMU-MP-1 after MI. The combination of an MST1/2 inhibitor and a BLT1 antagonist represents a promising strategy for combatting the effects of MI.

Microarray of Mst1/2 deleted epithelial cells from E18.5 mouse lungs

Project description:ShhCre;Mst1/2flx/flx (Mst1/2 D/D) mice were generated to conditionally delete Mst1 and Mst2 from epithelial progenitors during lung morphogenesis. Lungs from E18.5 control and Mst1/2 D/D mice were mechanically and enzymatically dissociated to generate single cell suspension. Epcam(+) cells were isolated using magnetic microbeads. Microarray analysis of mRNAs isolated from Epcam(+) epithelial cells from E18.5 control and Mst1/2 D/D mice was performed to identify transcriptional changes following deletion of the mammalian Hippo kinases (Mst1 and Mst2) from the embryonic lung. The mammalian Hippo kinases, Mst1 and Mst2, were conditionally deleted in epithelial progenitors of the developing lung using ShhCre. Epcam(+) epithelial cells were isolated from the lungs of E18.5 control and Mst1/2 deleted mice. mRNA isolated from Epcam(+) epithelial cells was analyzed by microarray.

RNA-seq analysis of Mst1/2 deleted bronchiolar epithelial cells from adult mouse lungs

Project description:Mst1 and Mst2 were conditionally deleted from non-ciliated bronchiolar epithelial cells in the mature lung. Bronchiolar epithelial cells from control and Mst1/2 deleted mice were isolated by cell sorting and used for RNA-seq analysis. Scgb1a1-rtTA/tetO-Cre/Mst1;2-flx/flx (Mst1/2 D/D) mice were generated to conditionally delete Mst1 and Mst2 from non-ciliated, secretory bronchiolar epithelial cells. Adult mice were maintained on doxycycline food for 16 days to induce deletion of Mst1/2. Lin-/CD326+/CD24-intermediate cells were isolated by fluorescence cell sorting to enrich for the targeted airway epithelial cells. mRNA isolated from Lin-/CD326+/CD24-intermediate cells from control and Mst1/2 D/D mice was pooled and analyzed by RNA-seq to identify transcriptional changes following deletion of Mst1 and Mst2 from mature lung bronchiolar epithelial cells.

RNA sequencing data from wild type and Mst1/2 knockout esophageal epithelium

Project description:Hippo signaling regulates the homeostasis of multiple organs. Mst1 and Mst2 (Mst1/2) are critical components of the Hippo signaling pathway. Here, we utilized RNA sequencing to determine the transcriptional change in the esophageal epithelium upon Mst1/2 deletion. The analysis of gene expression profiles allows us to understand the role of Mst1/2 in the regulation of various biological processes in the esophageal epithelium.
