MiRNA profiling from T-ALL cells

ABSTRACT: The NOTCH1 signaling pathway is a critical determinant of cell fate decisions and drives oncogenesis through mechanisms that are incompletely understood. To elucidate tumorigenic pathways that cooperate with activated Notch1 in leukemogenesis,we performed miRNA expression profiling of normal CD4+CD8+ thymocytes, non-malignant ICN1 over-expressing CD4+CD8+ cells and ICN1-induced tumor CD4+CD8+ cells. Three groups of the murine T cells: Control CD4+CD8+ normal thymocytes vs.non-malignant ICN1-expressing CD4+CD8+ cells vs. ICN1-tumor CD4+CD8+ cells .

MicroRNA expression array for 1833 cells expressing RKIP vs. control

Project description:RKIP has been implicated in suppression of breast tumor metastasis. Identification of microRNAs regulated by RKIP helps us to understand how RKIP suppresses tumor metastasis via its downstream target mircoRNAs and genes. Total RNA was extracted from 1833 cells expressing RKIP or control, respectively. Exiqon miRCURY LNA array v.11.0. was performed to identify the microRNAs regulated by RKIP.

MicroRNA array profiling on human pluripotent stem cell-derived cardiomyocytes exposed to doxorubicin

Project description:Cardiomyocytes derived from human pluripotent stem cells were exposed to the cardiotoxic drug Doxorubicin in order to assess the utility of this cell system as a model for drug-induced cardiotoxicity. Cells are exposed to different concentrations of doxorubicin for up to 48 hours followed by a 12 days recovery period.

Interplay between HIV-1 infection and host microRNAs

Project description:Using microRNA array analyses of in vitro HIV-1-infected CD4+ cells, we find that several host microRNAs are significantly up- or downregulated around the time HIV-1 infection peaks in vitro. While microRNA-223 levels were significantly enriched in HIV-1-infected CD4+CD8? PBMCs, microRNA-29a/b, microRNA-155 and microRNA-21 levels were significantly reduced. Based on the potential for microRNA binding sites in a conserved sequence of the Nef-3?-LTR, several host microRNAs potentially could affect HIV-1 gene expression. Among those microRNAs, the microRNA-29 family has seed complementarity in the HIV-1 3?-UTR, but the potential suppressive effect of microRNA-29 on HIV-1 is severely blocked by the secondary structure of the target region. Our data support a possible regulatory circuit at the peak of HIV-1 replication which involves downregulation of microRNA-29, expression of Nef, the apoptosis of host CD4 cells and upregulation of microRNA-223.

HuR and miR-1192 regulate myogenesis by modulating the translation of HMGB1 mRNA (mRNA)

Project description:Upon muscle injury the high mobility group box 1 (HMGB1) protein is up-regulated and secreted to initiate reparative responses. Here we show that HMGB1 controls myogenesis both in vitro and in vivo, during development and after adult muscle injury. HMGB1 expression in muscle cells is regulated at the translational level: the miRNA miR-1192 inhibits HMGB1 translation and the RNA-binding protein HuR promotes it. HuR binds to a cis-element, HuRBS, located in the 3'UTR of the HMGB1 transcript, and at the same time miR-1192 is recruited to an adjacent seed element. The binding of HuR to the HuRBS prevents the recruitment of Argonaute 2 (Ago2), overriding miR-1192-mediated translation inhibition. Depleting HuR reduces myoblast fusion and silencing miR-1192 re-establishes the fusion potential of HuR-depleted cells. We propose that HuR promotes the commitment of myoblasts to myogenesis by enhancing the translation of HMGB1 and suppressing the translation inhibition mediated by miR-1192. RNA content was extracted following immunoprecipitation of HuR using a monoclonal antibody (3A2) and the levels of mRNA were compared to an IgG control in order to determine which transcripts were enriched in the HuR ribonucleoprotein complex.
