MiRNA profiling in HIV-1 latently infected cells

ABSTRACT: 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 .

A3G and A3F CLIP

Project description:APOBEC3G and APOBEC3F are cell-encoded restriction factors that have evolved to counteract virus infections. When packaged into HIV-1 particles, A3G and A3F impair reverse transcription and induce the hypermutation of viral DNA. We employed a next generation sequencing approach to identify the RNAs that these proteins bind in HIV-1 infected cells and HIV-1 virions. We then analysed the mechanism of packaging of APOBEC3 in detail.

microRNA expression profile of dermal MSCs derived from psoriasis patients and normal control

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.
