Abstract/OtherAbstract:
We established a novel gene expression analysis platform, Multiplex Competitive RT-PCR Using Fluorescent Universal Primers (MCF-PCR), to study multi-gene expression patterns simultaneously. This platform combines fluorescent universal primers, multiplex competitive RT-PCR, and capillary electrophoretic separation, which ensures MCF-PCR a reliable, medium-throughput, cost-effective technology for gene expression profiling. With cloned standard DNAs, the detection limits, precision, and sensitivity of MCF-PCR were evaluated and compared with that of the assay without adding competitive templates and real-time PCR, respectively. The results showed that detection limit was 3.125 × 10(3) to 3.2 × 10(6) copies, and 10 % copy differences between two samples can be detected by MCF-PCR. To validate MCF-PCR, we analyzed expression profile of five genes in interleukin (IL)-4/IL-13 pathway in peripheral blood of 20 healthy adults and 20 allergic dermatitis patients; three genes including IL-4, IL-13, and STAT6 were found differentially expressed in the two sample groups, which maybe key players in IL-4/IL-13 immunological signaling pathway and need further function analysis.
