Project description:HOXC6 is a member of the HOX family, and its aberrant expression has been verified in a variety of cancers, such as prostate, breast,nasopharyngeal carcinoma,gastric, and ovarian cancers.Some studies suggest that HOXC6 might be involved in tumor initiation and progression.However, the role of HOXC6 in esophageal squamous cell carcinoma cells has not been fully investigated.Here we study how HOXC6 affects the malignant phenotype of esophageal squamous cell carcinoma cells
Project description:We have investigated expressed microRNA in cryo-preserved esophageal cancer tissues using advanced microRNA microarray techniques. Our microarray analyses reveal a unique microRNA expression signature composed of 40 genes which can distinguish normal from malignant esophageal tissue. Some microRNAs could be correlated with the different clinico-pathological classifications. For example, high hsa-miR-103, -107, -23b expression correlated with poor overall disease-free survival of esophageal cancer patients. These results indicate that microRNA expression profiles are important diagnostic and prognostic markers of esophageal cancer, which might be analyzed simply using economical approaches such as RT-PCR. Keywords: microRNA, esophageal squamous cell carcinoma cancer vs adjacent normal tissues
Project description:This study was designed to identify genes aberrantly expressed in esophageal squamous cell carcinoma (ESCC) cells. Three esophageal squamous cell carcinoma-derived cell lines and one normal human esophageal squamous cell line were analyzed.
Project description:Profiles of esophageal squamous cell carcinoma and normal esophageal normal epithelium normal cell line. Analysis provides validation of novel microRNA targets prediction algorithms. esophageal squamous cell carcinoma:14, normal epithelium cell:2

Project description:Purpose: Next Generation sequencing (NGS) has revolutionized system-based cellular pathway analysis. The purpose of this study was to conduct RNA-SEQ analysis after knocking down the gene MAFB in human esophageal squamous cell carcinoma cell line KYSE450 to observe the expression changes of the transcriptome genes
Project description:Eosinophils are present in several solid tumors and have context-dependent function. The role of eosinophils in the development of esophageal squamous cell cancer (ESCC), 85% of esophageal cancers worldwide, is unknown. Mice were treated with 4-nitroquinolone-1-oxide (4-NQO) for 8 weeks followed by vehicle for 8 weeks to induce esophageal squamous pre-cancer. Eosinophil depletion using three mouse models resulted in exacerbated 4-NQO tumorigenesis. RNA-sequencing on the whole esophagus of WT and ?dblGATA mice was done in the pre-cancer model to understand how the presence of eosinophils affects the pre-cancer esophageal environment.
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.
