MicroRNA-221/222 modulate intestinal T helper 17 cell response as a negative feedback rheostat downstream of IL-23

Project description:MicroRNA-221/222 receive activation signal from IL-23 and suppression signal from TGFb, and target Maf and IL-23R for degradation, therebt acting in an inflammatory arm of Th17 response, and works as a negative feedback rheostat to constrain otherwise feed-forward loop of inflammatory Th17 response in the gut.

Antisense miRNA-221/222 (si221/222) and control inhibitor (GFP) treated fulvestrant-resistant breast cancer cells

Project description:Full title: Expression data from antisense miRNA-221/222 (si221/222) and control inhibitor (GFP) treated fulvestrant-resistant breast cancer cells The expression of miR-221/222 were found to be upregulated in fulvestrant resistant breast cancer cells MCF7-FR compared to its drug-sensitive counterpart MCF7. To investigate the role of miR-221/222 in acquired resistance to fulvestrant, we lowered the level of miR-221/222 in MCF7-FR cells using miRNA inhibitors (antagomirs), and compared gene expression profiles before and after treatment. Fulvestrant-resistant breast cancer cells MCF7-FR (originated from drug-sentitive breast cancer model cell line MCF7) were transient-transfected by antigomirs targeting miR221 or miR222 (i.e. si221, si222). All three cell lines, MCF7-FR, siR221, siRNA222 were subjected to gene expression profiling.

miR-221/222 drive synovial fibroblast expansion and pathogenesis of TNF-mediated arthritis

Project description:MicroRNAs (miRNAs) constitute fine tuners of gene expression and are implicated in a variety of diseases spanning from inflammation to cancer. miRNA expression is deregulated in rheumatoid arthritis (RA), however, their specific role in key arthritogenic cells such as the synovial fibroblast (SF) remains elusive. We have shown in the past that the expression of the miR-221/222 cluster is upregulated in RA SFs. Here, we demonstrate that miR-221/222 activation is downstream of major inflammatory cytokines, such as TNF and IL-1β, which promote miR-221/222 expression independently. miR-221/222 expression in SFs from the huTNFtg mouse model of arthritis correlates with disease progression. Targeted transgenic overexpression of miR-221/222 in SFs of the huTNFtg mouse model led to further expansion of synovial fibroblasts and disease exacerbation. miR-221/222 overexpression altered the transcriptional profile of SFs igniting pathways involved in cell cycle progression and ECM regulation. Validated targets of miR-221/222 included p27 and p57 cell cycle inhibitors, as well as Smarca1 (a chromatin remodeling component). In contrast, complete genetic ablation of miR-221/222 in arthritic mice led to decreased proliferation of fibroblasts, reduced synovial expansion and attenuated disease. scATAC-seq data analysis revealed increased miR-221/222 gene activity in the pathogenic and activated clusters of the intermediate and lining compartment. Taken together, our results establish an SF-specific pathogenic role of the miR-221/222 cluster in arthritis and suggest that its therapeutic targeting in specific subpopulations should inform the design of novel fibroblast-targeted therapies for human disease.

Identification of genes differentially expressed in lung cancer cells after the transfection of miR-221 or miR-222.

Project description:To evaluate involvement of miR-221 and miR-222 in lung cancer, we investigated the effects of miR-221 and miR-222 overexpression on six lung cancer cell lines as well as one immortalized normal human bronchial epithelial cell line. Two cell lines, H3255 and H1299 with no replicates were studied. Cells were transfected with miR-221, miR-222, or miR control. Microarray analysis was done to identify genes differentially expressed in lung cancer cells after the transfection of miR-221 or miR-222.

MiR-221/222 suppression induced by activation of the cAMP/PKA/CREB1 pathway is required for cAMP-induced bidirectional differentiation of glioma cells [miRNA]

Project description:Factors that increase cAMP levels can induce lineage-specific differentiation of glioma cells into astrocyte-like cells. However, the differentiation pattern and underlying mechanisms remain unclear. Here, we find that cAMP/PKA/CREB1-induced miR-221/222 suppression contributes to the neuron-like differentiation of gliomas. cAMP agonists selectively induced neuron- and astrocyte-like but not oligodendrocyte-like differentiation of C6 glioma cells. PKA inhibitors and CREB1 knockout blocked neuron-like differentiation of glioma cells. cAMP inhibited miR-221/222 in a PKA/CREB1 dependent manner. Importantly, both in vitro and in vivo assays demonstrated that transcriptional suppression of miR-221/222 is required for neuronal differentiation of glioma cells. Our findings suggest that increasing cAMP levels can induce bidirectional differentiation of glioma cells. Furthermore, the miR-221/222 cluster acts as an epigenetic brake during glioma differentiation.
