Project description:Purpose:Cell division cycle associated 7 (CDCA7) is a copy number amplification gene that contributes to the metastasis and invasion of tumors, including esophageal squamous cell carcinoma (ESCC). This present study aimed at clarifying whether high expression of CDCA7 promotes the metastasis and invasion of ESCC cell lines and exploring the underlying mechanisms implicated in EMT of ESCC. Mehtod:We established KYSE150 cell lines in which target gene has been knocked down by shRNA and KYSE180 cell lines in which target gene has been ovexpressed by plasmid.We then performed gene expression profiling analysis using data obtained from RNA-seq of 4 different cells.Each cell has three repetions. Result:KEGG pathway enrichment analysis on the data of RNA-seq showed that Wnt signaling pathway and TGF-β signaling pathway which are related to EMT process were screened out. Conclusion:CDCA7 was heavily involved in EMT by regulating the expression of Smad4 and Smad7 in TGF-β signaling pathway.
Project description:To understand the difference of protein expression between paired esophageal squamous cell carcinoma (ESCC) and adjacent normal tissues, we collected 10 paired ESCC and normal tissues from surgical resected specimems for high-throughput proteomic experiments. From comparative analysis, the dysregulated signaling pathways in ESCC could be uncovered.
Project description:To discover ESCC related proteins, we used SWATH to quantify the protein abundance between ESCC and adjacent tissues. Briefly, we pooled 10 ESCCtissues and their corresponding adjacent tissues for SWATH acquisition with three replicates.Three DDA repeats were also acquired with the pooled 10-paired ESCC tissue.The trypsin digested peptide mixture was analyzed by AB SCIEX 5600 (AB SCIEX).The database searching procedure was achieved using ProteinPilot v4.5 (AB Sciex). The database is IPI_homo_sapiens_V3.87.
