Project description:In order to test the effects of metastasis suppressive miR-126/126* on primary tumor microenvironment, we designed a real-time PCR-based mouse cytokine/chemokine array containing 95 cytokines/chemokines and their receptors. Considering the possibility that production of cytokines/chemokines may be dependent on the interactions among different cell types within the tumor mass, we inoculated GFP-labeled 4T1 cells with a control vector or 4T1 cells with pri-miR-126 overexpression into the fat pad of BALB/c mice. 10 days later, we harvested the primary tumors, isolated GFP-positive cancer cells, and analyzed the expression levels of different cytokines/chemokines and their receptors in the cancer cells at the mRNA level using the cytokine array.
Project description:Microarray analysis and quantitative real-time PCR revealed that TB40E infection of DCs led to changes of the gene expression pattern. A variety of pro-inflammatory cytokines and chemokines (CXCL10, CXCL11, CCL5), TLR3 and genes whose products function downstream of the TLR3 signalling pathway (e.g. IFN-α, IFN-β) were significantly upregulated.
