Background and objectives
A variant located at the end of HDAC9 gene within clusters of DNAse I sensitivity zones and histone modification hotspots has been associated with large vessel stroke and could be linked to plaque instability. The aim of the study is to define if an altered expression of HDAC9, TWIST1 and FERD3L genes could be involved in plaque vulnerability.
Methods
Histological classification and gene expression analysis were performed in 6 stable and 16 unstable plaques obtained from asymptomatic patients undergoing endarterectomy. Gene expression was analysed by real-time PCR.
Results and conclusions
TWIST1 gene expression resulted higher in stable plaques (P < 0.02). HDAC9 gene expression followed a similar trend (P = 0.11). These results highlighting the significant correlation between TWIST and HDAC9 gene expression suggest that both genes may contribute to plaque stability in a coordinated way.
