Project description:Comparing to matched normal mucosa, WTX was lost in most of human gastric cancers (Zhang et al., 2016). We analyzed the microRNA expression profiling among WTX low human colorectal cancer tissues and matched adjacent WTX high normal colorectal mucosa. The aimed to identify the unique signature of miRNAs which related to WTX loss in human colorectal cancers.

Project description:Using the highly sensitive miRCURY LNA™ microRNA array, we screened 3100 microRNAs abundant in the human gastric cancer and Adjacent normal gastric mucosa tissues, and the function of differentially expressed microRNAs were analyzed by bioinformatics. The enrichment results indicated that these microRNAs perhaps participated in the occurrence and development process of gastric cancer.
Project description:Gastric cancer is one of the most common malignant tumors. Asia has a high incidence of gastric cancer globally. South Korea, Mongolia, Japan and China are the four countries with the highest incidence of gastric cancer in the world. Gansu province in China has the estimated age-standardized incidence rates and mortality rates by Chinese standard population of 62.34/100,000 and 36.94/100,000, respectively, in 2012, which are much higher than the average level of China (22.06/100,000 and 15.16/100,000) in the same year. As a high incidence area of gastric cancer in China, Wuwei city in Gansu province has the prevalence of gastric cancer almost 5 times higher than the average level nationwide. In this study, the cancer tissues and matched adjacent normal mucosa tissues of 5 patients with early gastric cancers who were treated with ESD in Gansu Wuwei Tumor Hospital and the First Hospital of Lanzhou University were collected. All of the patients are from Gansu, China. MicroRNA array was used to find the differences in microRNAs expression profile between the early gastric cancer tissues and the para-cancer normal tissues. It is expected to explore the reasons of the abnormal high incidence of gastric cancer in Gansu Province, China, from the aspect of microRNAs expression profile characteristics.
Project description:Using the highly sensitive miRCURY LNA™ microRNA array, we screened 3100 microRNAs abundant in the human colon cancer and Adjacent normal gastric mucosa tissues, and the function of differentially expressed microRNAs were analyzed by bioinformatics. The enrichment results indicated that these microRNAs perhaps participated in the occurrence and development process of colon cancer. In this study, three cases of colon cancer were used to acquire the microRNA expression profiling, and qPCR was employed to confirm the results of microRNA chip. The function of the differentially expressed microRNA were analyzed by bioinformatic methods.Finally,compared with the adjacent normal mucosa tissues，the expression of 2 microRNAs were up regulated in colon cancer. qPCR results showed an expression pattern consistent with that of the chip analysis.
Project description:By the high sensitive cricular RNA micro array, we commpared 10211 circular RNAs abundant in the human gastric cancer tissues and adjacent normal gastric mucosa tissues, and the functional role of differentially expressed circular RNAs were analyzed by bioinformatics. The enrichment results indicated that these circular RNAs may involevd in the occurrence and progression process of gastric cancer.
Project description:We used microarrays to determine global gene expression in primary tumor tissues (ESCC) and matched normal tissues (adjacent normal esophageal mucosa)
Project description:Biopsies from 24 gastric adenocarcinomas and adjacent normal gastric mucosa were analyzed for from 24 patients following surgical resection of the tumor. Genome-wide DNA methylation profiling of the tumor and matched non-cancerous mucosa was performed and compared to previously performed gene expression, survival and clinicopathological parametres.
