title: Establishment and application of minigene models for studying pre-mRNA alternative splicing.
abstract: The objective of the present study is to establish a minigene model for studying pre-mRNA alternative splicing. To prepare the minigene DNA constructs, with human or mouse genomic DNA as templates, GluR-B, FGF-2R and Zis "minigene" fragments were amplified using PCR and cloned to the eukaryotic expression vectors. The three constructed minigenes and the expression vectors of Tra2beta1 and Zis2 were co-transfected in Hela cells. RT-PCR analysis was performed to semi-quantitatively determine the spliced products from the minigenes. The results demonstrated that the constructed minigenes are useful in studying the pre-mRNA alternative splicing in cultured cells. With the established Zis minigene, we for the first time found that Zis2 isoform regulates the alternative splicing of Zis minigene.
