Project description:miRNAs comprise a family of small non-coding RNA molecules that have emerged as key post-transcriptional regulators of gene expression. Aberrant miRNA expression has been linked to various human tumors. This study was aimed to identify new aberrant expression miRNA in esophageal squamous cell carcinoma (ESCC) and invested the potential functions in this tumor. miRNA microarray analysis with 4 ESCC and adjacent non-tumor tissues was performed.
Project description:Sprouty proteins are evolutionarily conserved modulators of mitogen-activated protein kinase pathway. Sprouty2 appears to function as a tumor suppressor in cancers, whereas we reported earlier that Sprouty2 functions as an oncogene in colorectal cancer. To further understand the oncogenic potential of Sprouty2 in the colon, microRNA expression profile of colon cancer cells was investigated. Sprouty2 suppression in HCT116 colon cancer cells significantly increased MicroRNA 194-5p. Sprouty2 dependent regulation of microRNA194-5p and its biological targets were studied further for their tumor suppressive actions in reducing epithelial-mesenchymal transition in colorectal cancer. Sprouty2 knockdown was performed by infecting HCT116 cells with three different lentivirus expressing shRNAs against human Sprouty2 mRNA and a control non targeted non-silencing shRNA (Sprouty2 MISSION shRNA Lentiviral Transduction Particles; TRCN 0000007522, TRCN 0000231589, TRCN 0000231588 and a non-targeted shRNA control from Sigma) following lentiviral transduction protocols provided by Sigma. Due to the random integration of the lentivirus into the host genome, varying levels of Sprouty2 gene knockdown was expected in puromycin resistant colonies. Three colonies in triplicate that demonstrated highest to lowest level of Sprouty2 suppression, as assessed by western blotting, were selected. RNA samples from these colonies and one from non-targeted shRNA expressing colony were prepared for microRNA expression profile analysis. Pooled RNA samples from each group were shipped to Exiqon for microRNA profiling based on miRCURY LNATM array technology.
Project description:Several studies have suggested that MSCs have pleiotropic immuno-modulatory effects, including inhibition of T cell proliferation, suppression of NK cells proliferation, modulation of cytokine production, and inhibition of dendritic cell (DC) maturation etc. But the exactly mechanism are still largely unclear. We proposed to investigate the microRNA expression profile of psoriatic MSCs. 6 patients and 6 normal control were inrolled in the study, the microRNA expression profile of dermal MSCs were studied using the microarry.
Project description:We compared miRNA expression profiles among 5 groups of HepG2 cells treated with various concentrations (0,100,200 nM) of triptolide for 12 h or 24 h. Two-condition experiment, triptolide intervention vs. without intervention. Biological replicates: 3 control, 3 treated, independently grown and harvested. One replicate per array.
Project description:Herein expression trends of host miRNA were measured in HIV-1 latently infected and persistent replication cells, as well as the control cells. HIV-1 latency infection was established by infecting CEM-SS lymphocytes with HIV-1 Bru strain. After selection and long-term culture, the chronically infected cell showed the characteristics of latency definition: 1. The provirus was intergrated in to the host genome.2. No viral expression could be detected during culture.3 .Cell stimulators, such as TNFa,PMA, etc, reactivate the viral expression. As expected, miRNA trend was different in HIV-1 latency when compared to the control or HIV-1 replication. A subset of miRNAs is enriched in HIV-1 latency model. The observation reinforces the concept of active HIV-1 interplay with host small RNAs that modulate HIV-1 infection mode. In this study, the in vitro steady cell culture was used to explore the miRNA transcription signatures in HIV-1 infection. miRNA profiles were performed and compared among normal control,HIV-1 latency and HIV-1 replication .
