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

Project description:Esophageal squamous cell carcinoma (ESCC) patients are usually diagnosed at late stages, prohibiting the chance of surgical cure. The obstacle partly comes from the lack of molecular markers for early detection. Moreover, there is no consensus about endoscopic surveillance for ESCC. This study aimed to identify noninvasive markers for ESCC detection. By microarray-based screening of 17 pairs of human ESCC specimens, we identified that secreted protein matrix metalloproteinase-1 (MMP1) may be associated with the presence of ESCC.

Project description:Human esophageal cancer is the sixth leading cause of cancer death worldwide. More than 90% of esophageal cancer is esophageal squamous cell carcinoma (ESCC). However, the etiological cause of ESCC remains unclear. By using gene expression microarray analysis, we aimed to find whether fungal infection is involved in ESCC development. We identified a wide spectrum of molecular signatures in a fungal infection and ESCC mouse model, including alterations involved in epigenetic regulation, cell cycle control, cell proliferation and survival signaling, and inflammation, which share many similarities with human ESCC.

Project description:MicroRNAs (miRNAs) are an endogenous conserved class of non-coding 20–22 nt small RNAs that regulate gene expression at post-transcriptional level by mostly binding to 3′-UTR of target mRNAs, leading to mRNA degradation or translation inhibition. Recent reports demonstrate a role for miRNA expression in the disease progression and outcome. By now, many researcher focusing on miRNA expression profiles in Barrett's esophagus and esophageal adenocarcinoma have been reported. Nevertheless, there is still a little information available about specific miRNA expression pattern and their roles in ESCC. To develop novel diagnostic and therapeutic targets for esophageal squamous cancer, we first investigated the expression profile of miRNA in three pairs of ESCC clinical samples. Tissues of ESCC and the matched normal counterparts were obtained from surgical specimens immediately after resection from patients undergoing primary surgical treatment of esophageal carcinoma from the Department of Tumor Surgery of Shantou Central Hospital, China. RNA labeling and hybridization were completed by KangChen Bio-tech Inc. (Shanghai, China) according to the manufacturer's instructions. Briefly, total RNA from three pairs of esophageal carcinoma and matched normal tissues were isolated by Trizol (Invitrogen, USA) and purified by RNeasy mini kit (QIAGEN, German). The concentration and quality of total RNA were measured by NanoDrop ND-1000 at 260 and 280 nm (A260/280) and checked by gel electrophoresis. Each RNA sample from three pairs of ESCC was separately labeled either using the miRCURY Hy3/Hy5 labeling kit and hybridized on the six miRCURYTM locked nucleic acid (LNA) array version 11.0 (Exiqon, Denmark), which contains probes for 1700 mature miRNA. Scans were quantified by using GenePix software (Molecular Devices). The data were exported to Microsoft Excel worksheets, log2 transformed, normalized using global Lowess (Locally Weighted Scatter plot Smoothing) regression algorithm (MIDAS, TIGR Microarray Data Analysis System).

Project description:Esophageal squamous cell carcinoma (ESCC) is a heterogeneous cancer associated with high mortality rate. In India, it is the 6th most common cause of cancer-related mortality. In this study, we employed high-resolution mass spectrometry-based quantitative proteomics to characterize differential protein expression pattern associated with ESCC. We identified several differentially expressed proteins including PDPN, TOP2A, POSTN and MMP2 that were overexpressed in ESCC. In addition, we identified downregulation of esophagus tissue-enriched proteins such as SLURP1, PADI1, CSTA and small proline-rich proteins like SPRR3, SPRR2A, SPRR1A and CSTA, KRT4, KRT13 involved in squamous cell differentiation. We identified several overexpressed proteins belonging to 3q24-29 chromosomal region, corroborating CNV alterations in this region reported by several published studies. For example, we identified overexpression of SOX2, TP63, IGF2BP2 and RNF13 that are encoded by 3q26 region. Functional enrichment analysis revealed proteins involved in cell cycle pathways, DNA replication, spliceosome, and DNA repair pathways. We identified overexpression of multiple proteins that play a major role in alleviating ER stress. SYVN1/SEL1L complex forms the ER quality control machinery clearing misfolded proteins from ER. SYVN1 is an E3 ubiquitin ligase that ubiquitinates ER-resident proteins. There are also other non-canonical substrates of SYVN1 which are known to play a crucial role in tumor progression. Therefore, SYVN1 is a potential therapeutic target in ESCC.

Project description:We performed the integrative transcriptome analysis of human esophageal squamous cell carcinoma (ESCC) using Illumina high-throughput sequencing. A total of 187 million 38bp sequencing reads were generated containing 7 billion bases for three pairs of matched patient-derived ESCC clinical specimens and their adjacent non-tumorous tissues. By investigating the digital gene expression profiling, we found 1425 genes significantly differentially expressed and detected more than 9000 SNPs across all six samples. We also identified protein tyrosine kinase 6 (PTK6) as a novel tumor suppressor gene, which is critical in ESCC development. Analysis of whole transcriptome from 3 paired patient-derived ESCC clinical specimens and their adjacent non-tumorous tissues.
