RNAseq analyze global transcriptome of changes between siIRF3 and siYAP in Gastric cancer cells

ABSTRACT: Purpose: To investigate the signal crosstalk between IRF3 and YAP, RNA-sequencing (RNA-seq) was performed to analyze the genome-wide changes by the knockdown of IRF3 or YAP in HGC-27 cells. Methods: Total RNA was extracted from HGC-27 cell after transfection with negative control siRNA (n.c.), IRF3 siRNA (siIRF3) or YAP siRNA (siYAP). Then total RNA was quality controlled and quantified using an Agilent 2100 Bioanalyzer. After converting to cDNA and building library, high-throughput sequencing was performed using the Illumina HiSeq 2500 platform. Results: Approximately approximately one thousand transcripts showed differential expression between the siIRF3/siYAP and n.c., with a Fold-change>=2 and q-value <= 0.05. Gene ontology (GO) and gene set enrichment analysis (GSEA) showed a significant negative enrichment of YAP target genes identified by three independent studies in IRF3-knockdown condition. Conclusions: We conclude that RNA-seq based transcriptome characterization would provide a framework for understanding the signal crosstalk between IRF3 and YAP.

Genome-wide maps of IRF3 and YAP in gastric cancer cells.

Project description:We performed chromatin immunoprecipitation (ChIP) assays with YAP and IRF3 antibodies in HGC-27 cells. Analysis of the distribution of YAP- or IRF3-binding sites relative to genes annotated in the human genome, revealed that only a minute fraction of peaks mapped close (<1 kb) to transcription start sites (TSSs) whereas most peaks were located farther than 10 kb from the closest TSS. A total of 6,277 peaks were identified by both YAP and IRF3 antibodies.

Whole transcriptomes analyses of gastric cancer HGC-27 cell line treated with SHAP or control peptide

Project description:Purpose: To explore the molecular mechanisms of SHAP peptide (also termed as SOS) regulating gastic cancer tumorigenesis, RNA sequencing was performed to analyze the geome-wide change of SHAP treated HGC-27 cells compared to those of control peptide cells. Methods: Total mRNA was extracted from HGC-27 cells. Then RNA quality was assessed using an Agilent Bioanalyzer 2100 and the sample reads were sequenced using Illumina Hiseq 4000 platform. As a reasult, we got the transcript data using Hisat2 followed by Stringtie. qRT–PCR validation was performed using TaqMan and SYBR Green assays. Results: We mapped about 60 million sequence reads per sample to the human genome and identified about 58,000 transcripts in HGC-27 cells. Apprioximately 1,000 transcripts showed different expression between siSTRN3 and n.c. HGC-27 cells, with a fold change ≥2 and p value <0.05. Gene set enrichment analysis (GSEA) showed a significantly negative enrichment of Hippo target genes. Conclusion: Our study present the datiled transcripts analysis of HGC-27 cells, with biologic replicates. Based on RNA-seq transcriptome characterization , we conclude a molecular mechanism of SHAP regulating Hippo pathway in gastric cancer.

Expression data from HUVEC with YAP siRNA knockdown

Project description:YAP knockdown in HUVEC elicits proliferation and cell cycle preogression defects. YAP deficient cells caused arrest in G1 and defects in S-phase entry. The microarray analysis was conducted to identify potential YAP targets that are involved in HUVEC cell cycle regulation mRNA samples were collected from siRNA treated HUVECs 30 hour after transfection. Four biological replicates were used for each condition: control (RISC-free) and knockdown (siYAP#1 and siYAP#2)

Gene expression profiling of effect of Yap inhibition in a genetically engineered mouse model of hepatocellular carcinoma

Project description:Defective Hippo/YAP signaling in the liver results in tissue overgrowth and development of hepatocellular carcinoma (HCC). Here, we uncover mechanisms of YAP-mediated hepatocyte reprogramming and HCC pathogenesis. We show that YAP functions as a rheostat maintaining metabolic specialization, differentiation and quiescence within the hepatocyte compartment. Importantly, treatment with siRNA-lipid nanoparticles (siRNA-LNPs) targeting YAP restores hepatocyte differentiation and causes pronounced tumor regression in a genetically engineered mouse HCC model (mice with liver-specific Mst1/Mst2 double knockout). Furthermore, YAP targets are enriched in an aggressive human HCC subtype characterized by a proliferative signature and absence of CTNNB1 mutations. Thus, our work reveals Hippo signaling as a key regulator of positional identity of hepatocytes, supports targeting YAP using siRNA-LNPs as a paradigm of differentiation-based therapy, and identifies an HCC subtype potentially responsive to this approach. Mice with liver-specific Mst1/Mst2 double-knockout (Adeno-Cre injected Mst1-/-; Mst2Flox/Flox mice) were monitored for the formation of HCC by ultrasound imaging. Animals were then randomized to be treated by intravenous injection of either siYap-LNPs or siLuciferase-LNPs for a period of 9 days.

The effect of YAP/TAZ knockdown on the intestinal epithelium

Project description:The Hippo pathway plays a crucial in organ size control during development and tissue homeostasis in adult life. To examine a role for Hippo signaling in the intestinal epithelium, we analyzed gene expression patterns in the mouse intestinal epithelilum transfected with siRNAs or expression plasmids for shRNAs targeting the Hippo pathway effectors, YAP and TAZ. We performed two independent series of experiments (siGFP (n=3) vs siYAP/siTAZ (n=3), and shLacZ (n=1) vs shYAP/shTAZ (n=1)). Control siRNA (siGFP), YAP/TAZ siRNAs, or expression plasmids for control shRNA (shLacZ) or YAP/TAZ shRNAs were introduced into the mouse intestinal epithelium by the newly-developed in vivo transfection method. Four days after transfection, intestinal epithelial cells were isolated from the tissues and total RNA was extracted.
