A Transcriptional Regulatory Loop of Master Regulator Transcription Factors, PPARG, and Fatty Acid Synthesis Promotes Esophageal Adenocarcinoma


ABSTRACT: We profiled esophageal adenocarcinoma cell lines with chromatin immunoprecipitation sequencing (ChIP-Seq). Mathematically modeling was performed to establish (super)-enhancers landscapes and inter-connected transcriptional circuitry formed by master TFs. Coregulation and cooperation between master TFs was investigated by ChIP-Seq, RNA-Seq, 4C-Seq and luciferase assay. Biological functions of candidate factors were evaluated by measuring cell proliferation, colony formation, cell apoptosis and xenograft growth. Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. Here, we aim to compare of Eso26 or OE33 cells knock down PPARG with siRNA and control transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis. We also report the application of ChIP sequencing technology for studying master transcription factor (PPARG) in human esophageal adenocarcinoma cancer cell lines (Eso26 and OE33).
