RNA-seq of Paneth cells

Project description:The impact of removal of Mll1 in intestinal Paneth cells expressing an constitutively active form of beta-catenin (beta-cateninGOF) was analysed in 4 pairs of sorted Paneth cells of Lgr5-CreERT2; beta-cateninGOF;Mll1+/- (control) and Lgr5-CreERT2; beta-cateninGOF;Mll1-/- (knockout) mice at 10 days after tamoxifen-induced mutagenesis. Using 75-base-pair reads, around 30 million reads per sample with comparable unique mapped reads (52-93%) were obtained. To analyze differentially expressed genes, we applied DESeq2 analysis to the RNA-seq dataset. Differentially expressed genes in beta-cateninGOF; Mll1-/- versus beta-cateninGOF; Mll1+/- Paneth cells showed both up- and downregulation of genes at a false discovery rate (FDR) of 10%. This included a global increase in the expression of goblet cell-specific genes. Downregulated genes included specific markers of Paneth cells, indicating that ablation of Mll1 in Paneth cells shifted their identity towards a mixed Paneth-goblet cell fate.

RNA-seq of sorted intestinal stem and Paneth cells

Project description:The impact of Mll1 removal on the intestinal stem cells and its direct effect on neighbouring Paneth cells was evaluated in sorted intestinal stem and Paneth cells from Mll1FC/+; Lgr5-eGFP-CreERT2/+ (control) and Mll1FC/FC; Lgr5-eGFP-CreERT2/+ (knockout) mice, 4 and 10 days after tamoxifen-induced mutagenesis. Using 75-base-pair reads, 30 million reads per sample with comparable unique mapped reads for stem (70-77%) and Paneth (60-76%) cells were obtained. To analyze differentially expressed genes, we applied DESeq2 analysis to the RNA-seq dataset. Analysis by DAVID and GSEA at a false discovery rate (FDR) of 5% was conducted.The stem cell transcriptome revealed that Mll1 knockout stem cells exhibited a decreased expression of several transcription factors and stem cell genes. Additionally, Mll1 ablation in stem cells had an impact on Paneth cells. Downregulation of Paneth cell specific markers indicated a loss of Paneth cell identity.

Single cell RNA sequencing analysis of germ free (GF) mouse Paneth cells and microbiome-transferred exGF mouse Paneth cells.

Project description:The single cell level Paneth cell transcriptome under gnotobiotic condition has not been resolved. How gut microbiome modulates Paneth cell transcriptome at single cell level in germ-free mice was not known. We used a flow cytometry method to isolate highly pure ileal Paneth cells from germ free (GF) Paneth cell reporter mice (Lyz1-3'UTR-IRES-CreER) and from exGF Paneth cell reporter mice that were transplanted with wild type C57B/l6 mouse gut microbiota (exGF+B6M). These isolated Paneth cells were subjected to single cell RNA sequencing by 10xGenomics.

Metastasis of colon cancer requires Dickkopf-2 to generate cancer cells with Paneth cell properties

Project description:Metastasis is the leading cause of cancer-related mortality. Paneth cells provide stem cell niche factors in the homeostatic condition, but the underlying mechanisms of cancer stem cell niche development are unclear. Here we report that Dickkopf-2 (DKK2) is essential for Paneth-like cell generation during the metastasis of colon cancer. Splenic injection of DKK2-knockout (KO) cancer organoids into C57BL/6 mice resulted in a significant reduction of liver metastases compared to the control cancer organoids in spite of the presence of carcinogenic mutations in Apc, Kras and Tp53 genes. RNA-seq analysis of DKK2 KO organoids showed reduction of Paneth cell marker genes such as Lysozymes and Defensins. Ingenuity pathway analysis (IPA) of the RNA-seq data and assay for Transposase-Accessible Chromatin using sequencing (ATAC-seq) suggested HNF4A as a downstream target of DKK2. Chromatin immunoprecipitation followed by sequencing (Chip-seq) analysis showed that HNF4A binds to the open chromatin regions of Sox9, a well-known transcription factor for Paneth cell differentiation. Reduction of Paneth-like cells in the absence of DKK2 has been confirmed in the murine metastatic model of colon cancer using flow cytometry, immunohistochemistry and single cell RNA-seq. These data suggest the necessity of DKK2 in Paneth-like cell generation. Thus, DKK2 contributes to stem cell niche development during the metastatic progression of colon cancer.

Mouse duodenal and ileal Paneth cell single cell RNA sequencing

Project description:An indepth analysis of Paneth cell transcriptome at single cell level has not been available. Existing intestinal epithelial cell scRNA dataset contain many cell types, where Paneth cells represent a small portion. We used a flow cytometry based approach to enrich and isolate relatively pure Panethc cells from a newly developed Paneth cell reporter mouse line (Lyz1-3'UTR-IRES-CreER; Rosa26R-tdTomato). Single cell RNA sequencing was performed on purified duodenal and ileal Paneth cells of mice housed under specific pathogen free condition.
