The oncogenomic function of androgen receptor in esophageal squamous cell carcinoma is directed by GATA3

Project description:Esophageal squamous cell carcinoma (ESCC) is the sixth leading cause of cancer death worldwide. Emerging evidence suggests that the androgen receptor (AR) is involved in ESCC tumorigenesis. However, how AR exerts its genomic functions in ESCC remains unknown. Here, by defining AR cistromes and analyzing androgen-regulated transcriptomes, we find that AR downregulates the majority of its target genes in ESCC cells. We further find that the pioneer factor GATA3 governs AR-repressed transcription by recruiting SMRT/HDAC3 co-repressors to target gene loci. Importantly, genetic inhibition of GATA3 or pharmacological inhibition of AR/HDAC3 relieves AR-mediated gene repression, leading to ESCC cell growth inhibition in vitro and in vivo. Our findings reveal molecular mechanisms underlying the oncogenomic function of AR in ESCC and identify the GATA3-directed AR transcriptional repression program as a therapeutic target for ESCC.

Human esophageal dysplasia (16 cases) vs. esophageal squamous cell carcinoma (59 cases)

Project description:Our aim is to identify frequent genomic aberrations both in ESCC and esophageal dysplasia, and to discover important copy number-driving genes and microRNAs in ESCC. We carried out array-based comparative genomic hybridization (array CGH) on 59 ESCC resection samples and 16 dysplasia biopsy samples. Expression of genes at 11q13.3 was analyzed by real-time PCR and immunohistochemistry (IHC). Integrated analysis was performed to identify genes or microRNAs with copy number-expression correlations. Two group experiment, esophageal dysplasia vs. esophageal squamous cell carcinoma. Biological replicates: 16 dysplasias vs. 59 carcinomas

Expression data from esophageal squamous cell carcinomas and normal esophageal epithelia

Project description:Preoperative chemoradiotherapy (CRT) followed by surgery has been proved to improve esophageal squamous cell carcinoma (ESCC) patientsM-bM-^@M-^Y survival in comparison with surgery alone. However, the outcomes of CRT are heterogeneous, and no clinical or pathological method could predict CRT response. We aim to identify mRNA markers for ESCC CRT-response prediction through gene expression analyses. Gene expression analyses were performed on pretreatment cancer biopsies from 28 ESCCs who received neoadjuvant CRT and surgery and 10 normal esophageal epithelia using Affymetrix U133 Plus 2.0 arrays.

Gene expression profiling of Barrett's esophagus, adenocarcinoma, esophageal squamous epithelium and squamous cell carcinoma

Project description:The aim of this study is to generate and validate biomarkers to stratify patients with Barrett’s esophagus in terms of risk for developing cancer. We studied gene expression profiling in 69 frozen specimens, consisting of esophageal squamous epithelium from 19 healthy subjects, 20 specimens from patients with Barrett’s esophagus and 21 cases of esophageal adenocarcinoma, 9 cased of esophageal squamous cell carcinoma by whole genome microarray analysis. Laser capture microdissection technique was applied to procure cells from defined regions of Barrett’s esophagus metaplasia and esophageal adenocarcinoma. Microarray results were validated by quantitative real-time polymerase chain reaction (qRT-PCR) in an independent cohort consisting of 42 cases. Furthermore, immunohistochemistry was performed using antibodies to two selected target molecules on a third independent cohort of 36 specimens, consisting of 36 cases. A total of 1176 genes were associated significantly with esophageal adenocarcinoma. The expression pattern of a 4 gene signature with the highest discriminant score based on linear discriminant analysis (GeneSpring GX10.2), was identified and validated by qRT-PCR in independent cohort. Gene expression profiling of 20 specimens of Barrett's esophagus patients, 21 specimens of adenocarcinoma patients and 19 biopsies from patients with normal esophageal squamous epithelium, 9 specimens of squamous cell carcinoma were studied.
