Project description:Circular RNAs (circRNAs) are key regulators in the development and progression of human cancers. A human circRNA microarray analysis was performed to screen for abnormally expressed circRNAs in breast cancer tissue and circRNA-000911 was identified as a circRNA which was significantly downregulated in breast cancer cells. Mechanistic investigations suggested that the enhanced expression of circRNA-000911 suppressed cell proliferation, migration and invasion, and promoted the apoptosis of breast cancer cells. The overexpression of circRNA-000911 may provide a future direction which may aid in the development of a novel treatment strategy for breast cancer.
Project description:Purposes: To investigate the biological function of tRF in breast cancer by tRF and tiRNA sequencing Methods: Breast cancer tissue samples and matched non-tumor adjacent tissues were obtained from five patients. Small RNA sequencing was performed on Illumina NexSeq instrument Results: If P ≤ 0.05, fold change ≥ 2 as the cut off, there were 3 up-regulated tRFs & tiRNAs and 13 down-regulated tRFs & tiRNAs. Conclusions:There were 3 up-regulated tRFs & tiRNAs and 13 down-regulated tRFs & tiRNAs in breast cancer tissue samples and matching adjacent tissue samples
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:Circulating transcriptional landscapes between breast cancer tissues and adjacent normal tissues were compared using the Affymetrix Human OE LncRNA Microarray with probes for profiling of 63542 human lncRNAs. Goal was to investigate potential lncRNAs involved in breast cancer progression.
