Whole transcriptomes analyses of gastric cancer HGC-27 cell line treated with SHAP or control peptide
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. Overall design: Total mRNA was extracted from  HGC-27 cells treated with SHAP or control peptide. The quality was assessed using Agilent 2100, and the profiles were sequenced on the Illumina NovaSeq 6000.
