Project description:Rationale: The Id1 and Id3 genes play major roles during cardiac development, despite their expression being confined to non-myocardial layers (endocardium – endothelium - epicardium). We previously described that Id1–/–Id3–/– double knockout (dKO) mouse embryos die at mid-gestation from multiple cardiac defects, but early demise precluded the studies of the roles of Id in the adult mice. Objective: To elucidate postnatal roles of Id genes in the heart. Methods and Results: We ablated Id1 gene in the vasculature and Id3 gene globally to generate Tie2Cre+Id1F/–Id3–/– and Tie2Cre+Id1F/FId3–/– conditional KO (Id cKO) embryos. Half of the Id cKO mice die at birth. Postnatal demise was associated with cardiac underdevelopment, enlargement, muscular ventricular septal and endothelial defects. Surviving Id cKO mice exhibited dilated, fibrotic cardiomyopathy associated with defects in the vasculature. The adult cardiac phenotype progressed into heart failure and resembled endomyocardial fibroelastosis. An abnormal vascular response was also observed in the healing process of excisional skin wounds of Id cKO mice. Expression patterns of vascular, fibrotic and hypertrophic markers were altered in the Id cKO hearts, but addition of Insulin-Like Growth Factor binding protein-3 (IGFbp3) reversed gene expression profiles of vascular and fibrotic, but not hypertrophic markers. Conclusions: Conditional ablation of Id genes in the vasculature leads to dilated fibrotic cardiomyopathy. The findings could reveal important insights into the role(s) of the endocardial network of the endothelial lineage to the development of dilated fibrotic cardiomyopathy and identify a potential therapeutic target, IGFbp3, in its treatment.

Total RNA from heart tissue was isolated (RNeasy, QIAGEN) from P180 WT, Id control, Id cKO, IGFbp3 incubated Id cKO, and control incubated Id cKO. RNA was converted to cDNA, cRNA, and hybridized to DNA sequences contained in the GeneChip Mouse Gene 1.0 ST Array (Affymetrix). Information from at least duplicate samples was compared and filtered by fold change >2 (Id cKO vs WT, Id control vs WT, IGFbp3 incubated Id cKO vs. control incubated Id cKO) and statistical p-value<0.001.

Project description:TCF3 belongs to E protein family and has the function of transcription factor. TCF3 can directly interact with HLH family proteins ID1 and ID3 to play biological functions. ID1 and ID3 do not have the ability to directly bind to DNA and need to be regulated by TCF3. We found changes in pluripotency in ID1 and ID3 double knockout lines of human ESC, so we suspected that ID1 / 3 played a regulatory role through TCF3. Therefore, TCF3 ChIP-seq was done in WT and KO lines, hoping to find the downstream genes regulated by ID1 / 3 through TCF3, and then regulate hESC pluripotency through these genes.

Project description:Id proteins are dominant negative regulators within the HLH family of proteins. In embryonic stem cells (ESCs), Id1 and Id3 maintain the pluripotent state by preventing neural differentiation. The Id1-interacting protein Zrf1 plays a crucial role as a chromatin-bound factor in specification of the neural fate from ESCs. Here, we show that Id1 blocks Zrf1 recruitment to chromatin, thus preventing the activation of neural genes during ESC differentiation. Moreover, genetic deletion of Id1 in ESCs caused misexpression of more than 6000 genes. Interestingly, the expression of almost half of those genes was restored upon further depletion of Zrf1. We therefore identified Zrf1 as a transcriptional regulator downstream of Id1 in ESCs.

Four replicates corresponding to four independent biological samples per group were collected.

Project description:Id1 and its closely related family member Id3 are expressed by a diversity of stem and progenitor cells. We show that Id1/3 are required for the self-renewal and proliferation of triple negative breast cancer (TNBC) cells both in vitro and in vivo. Furthermore, we identified that Id1/3 negatively regulates the tumour suppressor gene Robo1. Depletion of Robo1 could rescue the proliferative defect induced by Id1/3 knockdown. To understand the mechanisms by which Robo1 rescues cell proliferation in Id1/3 depleted cells, we performed RNA-Sequencing on 4T1 cells with Dox-inducible Id1/3 KD and/or Robo1 depletion using siRNA. We conclude that following Id1/3 knockdown, Robo1 is induced and exerts anti-proliferative effects via suppression of a Myc transcriptional program.
