A splicing regulatory axis of SRSF2-NUMB-NOTCH governs the generation of hemogenic endothelial progenitors derived from human pluripotent stem cells

ABSTRACT: Purpose: The goals of this study are to verify the dynamic changes of hematopoietic endothilium treated by PLB in H1 derived different population of cells during human early hematopoietic differentian. Methods: mRNA profiles of hESC samples collected from FACS sorted APLNR+ cells treated with PLB during day 2.5 to 5 after hematopoiesis differentiation were generated by deep sequencing using Illumina HiSeq. The sequence reads that passed quality filters were analyzed at the gene and transcript isoform level STAR followed by Cufflinks. The differentially expressed splicing events were analyzed by rMASTs Conclusions: Our study represents the first detailed analysis the change of hemogenic endothelial progenitors generation treated by PLB , with biologic replicates, generated by RNA-seq technology. By detaied analysis of this data,we found splicing inhibition gave rise to the aberrant splicing of NUMB, which consequently led to the reduced expression of NUMB-S isoform in HEPs

Regulation of NUMB alternative splicing by RBM5, RBM6 and RBM10 controls cancer cell proliferation

Project description:RBM5, a regulator of alternative splicing of apoptotic genes, and its close homologues, RBM6 and RBM10, are RNA binding proteins frequently deleted or mutated in lung cancer. We report that RBM5/6 and RBM10 antagonistically regulate the proliferative capacity of cancer cells and display distinct positional effects in alternative splicing regulation. We identify the Notch pathway regulator NUMB as a key target of these factors in the control of cell proliferation. NUMB alternative splicing, which is frequently altered in lung cancer, can regulate colony and xenograft tumor formation and its modulation recapitulates or antagonizes the effects of RBM5, 6 and 10 in cell colony formation. RBM10 mutations identified in lung cancer cells disrupt NUMB splicing regulation to promote cell growth. Our results reveal a key genetic circuit in the control of cancer cell proliferation.

Effects on mRNA levels of a Numb and Numb-like conditional knockout in skeletal muscle fibers

Project description:We investigated the gene expression changes resulting from loss of Numb from skeletal muscle fibers using a conditional, inducible knockout of Numb and its close homolog Numb-like (NumbL) bulk RNA-sequencing.

Numb variant specific transcriptome analysis

Project description:Numb has 4 known variants and we are reporting two novel Numb variants, Numb5 and Numb6 in this study. The metastaticability variations between the numb variants were evaluated through the transcriptome. breast cancer cells were transfected with GFP-Numb4, GFP-Numb5, GFP-Numb6 or GFP-only vectors and their transcriptome were assessed on Affymetrix platform

Targeting mitophagy in SRSF2 mutant hematologic malignancies

Project description:Recurrent Glycogen synthase kinase-3 (GSK-3) phosphorylates multiple splicing factors, including SRSF2, and regulates the splicing of a broad range of mRNAs in human cells. Inhibition of GSK-3 disrupts splicing and promotes cell death in hematopoietic cells with heterozygous mutations in SRSF2 and not in cells with wild-type splicing factors. To characterize how GSK-3 inhibition alters the cellular proteome in SRSF2-P95H/+ cells, we have performed quantitative mass spectrometry (qMS) on K562 cells with SRSF2P95H/+ knocked into the endogenous locus (PMID 30799057) and parental K562 cells, treated with the GSK-3 inhibitor CHIR99021. We focused on the mitochondrial proteome using human proteome (UniprotKB) and mitochondrial (MitoCarta 3.0) databases for protein identification, identifying 163 mitochondrial proteins whose levels are affected by SRSF2 mutation.

Comprehensive Identification of Phosphorylation Sites on the Numb Endocytic Adaptor Protein

Project description:Numb is an endocytic adaptor protein that functions in the endocytosis and intracellular trafficking of membrane receptors and adhesion molecules. Numb localization and function have been shown to be regulated by phosphorylation through atypcial protein kinase C at several key sites. Here, we use Liquid Chromatogrpahy, Tandem Mass Spectrometry to identify additional Numb phosphorylation sites not yet characterized.

numb and numblike deleted by Nkx2.5Cre

Project description:The ventricular wall of the heart is composed of trabeculated and compactlayers, which are separated by yet unknown processes during embryonic development. Notch signaling plays important roles in cardiac development. Mutations in Notch signaling components are related to human congenital heart diseases Two homologues, Numb and Numblike (Numbl), are expressed in mammals, which also act as inhibitors of Notch signaling Here we investigate the role of Notch2 and Numb/Numblike during myocardial trabeculation and compaction. The aim of the experiment is to analyze whether Numb/Numblike are involved in inhibition of Notch activity in the developing heart.
