SOX9: a Stem Cell Transcriptional Regulator of Secreted Niche Signaling Factors

Project description:Mouse hair follicles undergo synchronized cycles. Cyclical regeneration and hair growth is fueled by hair follicle stem cells (HFSCs). We used RNA-seq to identify SOX9-dependent transcriptional changes and ChIP-seq to identify SOX9-bound genes in HF-SCs. Telogen quiescent hair follicle stem cells (HFSCs) and intefollicular epidermal cells (IFE) were FACS-purified for ChIP-sequcencing and HFSCs for RNA-Sequencing

Identifying NFIB target genes in mammalian cells

Project description:NFIB is a transcription factor that can both positively and negatively regulate gene transcription. We have identified NFIB as an arginine methylation substrate of CARM1. To elucidate how CARM1 could regulate NFIB target genes by methylating NFIB, we performed this ChIP-seq to firstly identify NFIB direct binding gengs.

Genome-wide map of NFIB/MLL1 complex binding and H3K4me3 deposition during osteogenic differentiation of C3H10T1/2 mesenchymal stem cells

Project description:To explore direct targets of NFIB/MLL1 complex and to examine the role of NFIB/MLL1 complex in genome-wide deposition of histone H3-K4 tri-methylation (H3K4me3), we conducted chromatin immunoprecipitation (ChIP) followed by deep sequencing (ChIP-seq) analysis of six different samples at two time points.

The NFIB/CARM1 Partnership is a Therapeutic Target for Small Cell Lung Cancer

Project description:This project identified NFI family members as CARM1 substrates. NFIB was previously reported to play a critical role in the development of small cell lung cancer. We provided evidence that the arginine methylation of NFIB is required for its oncogenic function in small cell lung cancer.

Hepatocyte-specific knock-out of Nfib aggravates hepatocellular tumorigenesis via enhancing urea cycle

Project description:Purpose: Nuclear Factor I B (NFIB) has been reported to promote tumor growth, metastasis, and liver regeneration, but its mechanism in liver cancer is not fully elucidated. The present study aims to reveal the role of NFIB in hepatocellular carcinogenesis Methods:In our study, we constructed hepatocyte-specific NFIB gene knockout mice with CRISPR/Cas9 technology (Nfib-/-; Alb-cre), and induced liver cancer mouse model by intraperitoneal injection of DEN/CCl4 Results: First, we found that Nfib-/-; Alb-cre mice developed more tumor nodules and had heavier livers than wild-type mice. H&E staining indicated that the liver histological severity of Nfib-/- group was more serious than that of WT group. Then we found that the differentially expressed genes in the tumor tissue between Nfib-/- mice and wild type mice were enriched in urea cycle. Furthermore, ASS1 and CPS1, the core enzymes of the urea cycle, were significantly upregulated in Nfib-/- tumors. Subsequently, we validated that the expression of ASS1 and CPS1 increased after knockdown of NFIB by lentivirus in normal hepatocytes and also promoted cell proliferation in vitro. In addition, ChIP assay confirmed that NFIB can bind with promoter region of both ASS1 and CPS1 gene Conclusions:Our study reveals for the first time that hepatocyte-specific knock-out of Nfib aggravates hepatocellular tumor development by enhancing the urea cycle.

NFIB is a driver of SCLC initiation, progression and metastasis in mouse and marks metastatic disease in patients

Project description:Small Cell Lung Cancer (SCLC) is the most aggressive type of lung cancer with early metastatic dissemination and invariable development of resistant disease for which no effective treatment is available to date. Mouse models of SCLC based on inactivation of Rb1 and Trp53 developed earlier showed frequent amplifications of two transcription factor genes: Nfib and Mycl. Overexpression of Nfib but not Mycl in SCLC mouse results in an enhanced and altered metastatic profile, and appears to be associated with genomic instability. NFIB promotes tumor heterogeneity with the concomitant expansive growth of poorly differentiated, highly proliferative, and invasive tumor cell populations. Consistent with the mouse data, NFIB expression in high-grade human neuroendocrine carcinomas correlates with advanced stage III/IV disease warranting its further assessment as a potentially valuable progression marker in a clinical setting. Genomic DNA from mouse small cell lung tumor samples was analyzed by mate pair sequencing and low coverage sequencing. And RNA from Nfib overexpressing mouse small cell lung cancer cell lines was further analyzed for high quality RNA profiles using Illumina Hiseq2500. This series contains only RNA-seq data.
