Outline of Final Research Achievements |
The mechanism of smooth muscle cells (SMCs) phenotypic change is one of the most important question in vascular diseases, yet, little is known regarding what plays the role of SMCs switch. SRF acts as the key transcription factor controlling SMCs specific genes, and many factors regulate SRF positively or negatively. Here we show that histone methyltransferase, Nsd1 is upregulated in synthetic SMCs compare with contractile SMCs, and knocking down Nsd1 using small interfering RNA occur SMC phenotypic change from synthetic state to contractile state in cultured high passage rat SMCs. Homozygous Nsd1 mutant mice exhibited little neointimaformation after vascular injury. Our present study suggested that Nsd1 act as SMC phenotyping switch, then inhibition of Nsd1 expression or activity could be available in vascular injury.
