Project description:Non-canonical microRNAs (miRNAs) are a class of short endogenous RNA molecules with the ability to control development, autophagy, apoptosis and the stress response in eukaryotes by pairing with partially complementary sites in the 3' untranslated regions (UTRs) of targeted genes. Recent studies have demonstrated that miRNAs serve as critical effectors in intricate networks of host-pathogen interactions. Thereforce, the differential expression of miRNAs were evaluated in Madin-Darby bovine kidney (MDBK) cells infected with bovine viral diarrhea virus (BVDV) NADL (100 TCID50/ 0.1 ml) for 6 h compared to normal MDBK cells using Solexa high-throughput sequencing technology (BGI, China).

Project description:Chronic infection of M. hyorhinis is postulated to be associated with cancer cell migration and invasion. To explore the mechanisms of M. hyorhinis-promoted invasiveness, we performed Affymetrix genechip (HuGene-1_0-st) analysis to examine differential gene expression profiles between non-infected and infected gastric cancer cells. We used microarrays to detail global programme of gene expression and identified distinct classes of upregulated genes after M. hyorhinis infection of gastric cancer cell lines. noninfected or M. hyorhinis-infected gastric cancer cells were utilized for RNA extraction and hybridization on Affymetrix microarrays.
