Abstract
The MMP-9-1562C/T polymorphism influence incidence and course of many diseases of the central nervous system. We found, using luciferase assays and Q-RT-PCR technique, allele-specific in-fluence of MMP-9-1562C/T polymorphism on the MMP-9 promoter activity and on the expression of MMP-9 mRNA in human neurons derived from SH-SY5Y cells. Then, we have elucidated the mechanism responsible for the allele-specific action of the MMP-9-1562C/T polymorphism on transcriptional regulation of the MMP-9 gene using pull-down assay combined with mass spec-trometry analysis, EMSA and EMSA supershift techniques, as well as DsiRNA-dependent gene silencing. We have found that MMP-9 promoter activity and MMP-9 mRNA expression are reg-ulated in human neurons in the MMP-9-1562C/T allele-specific manner with stronger upregulation conferred by the C allele. Moreover, we have revealed that the allele-specific action of the MMP-9-1562C/T polymorphism on the neuronal MMP-9 expression is related to HDAC1 and ZNF384 transcriptional regulators. We show that HDAC1 and ZNF384 bind differentially to the C and the T alleles forming in vitro different regulatory complexes. Moreover, our data demonstrate that HDAC1 and ZNF384 downregulate differentially the MMP-9 gene promoter activity and MMP-9 mRNA expression in vivo in human neurons acting mostly via the T allele.
