Project description:To explore the potential role of circular RNAs in gastric cancer, we employed microarray profiling as a discovery platform. Circular RNA expression was analyzed in three paired gastric cancer and adjacent non-tumor tissues using the Arraystar Human circRNA microarray V2 (Agilent one-color). Quantile normalization and statistical testing identified circRNAs differentially expressed between tumor and non-tumor tissues, providing candidate biomarkers for gastric cancer.
Project description:Copy number variation profiling of gastric tissues comparing gastric cancer tissues with matched adjacent noncancerous tissues. Goal was to determine the effects of chromosomal imbalances on gene expression and carcinogenesis or progression.

Goal was to determine the effects of chromosomal imbalances on gene expression and carcinogenesis or progression. 27 pairs of gastric tissues: gastric cancer tissues vs. matched adjacent noncancerous tissues.
Project description:To elucidate gene expression associated with copy number changes, we performed a genome-wide copy number and expression microarray analysis of 25 pairs of gastric tissues. 25 pairs of gastric tissues: gastric cancer tissues vs. matched adjacent noncancerous tissues.
Project description:Purpose: To investigate the role and mechanism of mRNAs, long chain non-coding RNAs and circular RNAs in gastric cancer. Methods: RNA-seq of ribosomal RNA-depleted total RNA were performed to screen differential expressed mRNAs, long chain non-coding RNAs between paired gastric cancer tissues and adjacent normal tissues.For the linear RNA was digested with 3 U of RNase R per µg of RNA. Results: A total of 83672 mRNAs, 105998 long chain non-coding RNAs, 25441 distinct circRNAs were identified in these samples, and 13929 of these circRNAs were identified as novel circRNAs.
Project description:Purpose: To investigate the role and mechanism of circRNAs in gastric cancer. Methods: RNA-seq of ribosomal RNA-depleted total RNA and qRT-PCR were performed to screen differential expressed circRNAs between paired gastric cancer tissues and adjacent normal tissues. Results: A total of 57623 distinct circRNAs were identified in these samples, and 35120 of these circRNAs contained at least two independent back-spliced reads in at least two samples. Compared with circBase, we found that there were 29007 matched circRNAs and 28616 novel circRNAs in our study.
Project description:To determine the circRNA expression profile in CRC and matched non-tumor tissues, we used circRNA microArray analysis form Arraystar to examine the expression of circRNAs in CRC and matched non-tumor tissues.
Project description:To determine the circRNA expression profile in HCC and matched non-tumor tissues, we used circRNA microArray analysis form Arraystar to examine the expression of circRNAs in HCC and matched non-tumor tissues.
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.
