Project description:Cancer cells associated with radioresistance are likely to give rise to local recurrence and distant metastatic relapse. However, it remains unclear whether specific miRNAs have direct roles in radioresistance and/or prognosis. In this study, we performed a human miRNA expression array analysis to identify miRNAs upregulated or downregulated in the radioresistant cells. To confirm the results, we selected several candidate miRNAs according to the fold change and function of miRNAs, and detected their expression levels in the radioresistant cells and their parental cells using qRT-PCR. Moreover, we further investigate that specific miRNAs predicts pathological response to preoperative radiotherapy in locally advanced ESCC
Project description:Oral squamous cell carcinoma (OSCC) is not significant improved in prognosis despite advancement in treatments. The presence of treatment resistant OSCC is responsible for stagnation in the survival rate. The inter-cellular communications between tumor cells is one of the molecular mechanisms involved in the acquisition of treatment resistance of OSCC. Extracellular vesicles (EVs) and encapsulated miRNAs are important mediators of the inter-cellular communication. We searched for miRNAs involved in radioresistance of OSCC, in order to elucidate the mechanism of acquisition of radioresistance
Project description:The purpose of this study is to explore the miRNAs expression profiles from esophageal squamous cell carcinoma (ESCC) and matched normal adjacent tissue.
Project description:The purpose of this study is to explore the miRNAs expression profiles in the serum from esophageal squamous cell carcinoma (ESCC) patients.
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:H.pylori colonization in esophageal mucosa increases the expression of CDX2 and COX-2 and exacerbates inflammation of the lower esophagus. However, the regulatory mechanisms have not been clearly defined.To investigate the effect of chronic repeated exposure of H.pylori on esophageal squamous epithelial cells in an in vitro model. To screen the microRNA profiles associated with H.pylori infection in esophageal epithelial cells, and to investigate the regulatory mechanisms of miRNAs on COX-2 and CDX2.The expression profiles of miRNAs in H. pylori infected cells were analyzed by microarray. To confirm the validity of the results, the significantly altered miRNAs were identified by quantitative RT-PCR. The potential targets of miRNAs were screened using Targetscan.
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: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.
