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.

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. The tumor and adjacent normal tissues were obtained from 17 male ESCC patients who underwent total esophagectomy without previous cancer treatment at Kaohsiung Medical University Hospital (KMUH)

Project description:A proportion of superficial esophageal squamous cell carcinoma, a type of less invasive esophageal squamous cell carcinoma (ESCC), would have metastasis after esophagectomy or endoscopic resection with poor prognosis. The purpose of this study was to discover the whole-genome copy number alteration (CNA) profiles of superficial ESCC and compare the CNAs of superficial ESCC patients with and without metastasis after surgery. Thirty eight superficial ESCC cases, including 19 cases with metastasis and 19 cases without metastasis within 5 years after surgery, were analyzed CNAs by Affymetrix OncoScan™ FFPE Assay. A 39-gene signature was initially constructed to identify high risk of metastasis in superficial ESCC patients. In addition, amplification of 11q13.3 (FGF4) and deletion of 9p21.3 (CDKN2A) were identified as recurrent CNAs across all 38 superficial ESCC cases. And amplifications of 3p26.33 (SOX2-OT), 8q24.21 (MYC), 14q21.1 (FOXA1) and deletion of 3p12.1 (GBE1) were identified as recurrent CNAs among metastasis cases only. Our study provided a 39-gene signature tool to identified high risk metastasis in superficial ESCC and suggested that amplifications of SOX2-OT, MYC, FOXA1 genes and deletion of GBE1 gene might play a vital role in metastasis among superficial ESCC.

Project description:Esophageal cancer is one of the most aggressive cancers and the sixth leading cause of cancer death worldwide. Approximately 70% of the global esophageal cancers occur in China and over 90% histopathological forms of this disease are esophageal squamous cell carcinoma (ESCC). Currently, there are limited clinical approaches for early diagnosis and treatment for ESCC, resulting in a 10% 5-year survival rate for the patients. Meanwhile, the full repertoire of genomic events leading to the pathogenesis of ESCC remains unclear. Here we show a comprehensive genomic analysis in 158 ESCC cases, as part of the International Cancer Genome Consortium (ICGC) Research Projects (http://icgc.org/icgc/cgp/72/371/1001734). We conducted whole-genome sequencing in 17 ESCC cases and whole-exome sequencing in 71 cases, of which 53 cases and additional 70 ESCC cases were subjected to array comparative genomic hybridization (a-CGH) analysis. We conducted whole-genome sequencing in 17 ESCC cases and whole-exome sequencing in 71 cases, of which 53 cases and additional 70 ESCC cases were subjected to array comparative genomic hybridization (a-CGH) analysis.

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: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.
