Project description:Altered levels of microRNAs (miRNAs) in blood may contribute to identification of individuals with lung cancer (LC) but may also be early systemic signals of increased LC risk. We compared expression of 1663 miRNAs in blood collected during diagnostic workup for confirmed LC cases (n=128) to that in individuals with suspected but confirmed negative LC (n=62) and identified nine candidate miRNAs upregulated in LC cases. Higher expression of three candidates, miR-320b, 320c, and 320d, was associated with poor survival, independent of LC stage and subtype. To investigate pre-diagnostic profiles of the candidate miRNAs, we assessed their blood expression up to eight years prior to LC diagnosis in population-based cohorts compared to matched controls (n=360 cases, 375 controls). Expression of miR-320c and miR-320d was higher especially in cases sampled within two years prior to LC diagnosis. Thus, elevated levels of miR-320c and miR-320d may be early indications of severe LC.

Project description:Hepatitis B virus-related liver cirrhosis (HBV-LC) is susceptible to bacterial infections, which could lead to adverse prognosis in patients. MicroRNA (miRNA) is easily detected in peripheral blood and is involved in multiple liver diseases. This pilot study aimed to investigate the differentially expressed (DE) miRNAs in the serum of patients with HBV-LC and bacterial infection, and to identify the potential biomarker. The clinical samples was collected, including four patients with HBV-LC and infection, four patients with HBV-LC without infection, four patients with chronic hepatitis B (CHB) and four healthy controls. miRNA expression was analyzed by Affymetrix GeneChip miRNA 4.0 Array. A total of 385 DE miRNAs (upregulated, 160; downregulated, 225) were detected in patients with HBV-LC and infection compared with patients with HBV-LC without infection.
