Research Abstract |
To investigate the relationship of miRNA alterations and chemosensitity, we investigated hsa-miR-451 and hsa-miR-498 expression in gastrointestinal tract tumors. Further, we examined also methylation and acetylation statues of TUBB3 promoter region. Demethylation and hyperacetylation at the promoter well correlated with overexpression of TBBU3 proteinn expression. Down-regulation of hsa-miR-451 and hsa-miR-498 induced ABCG2 overexpression. These results suggested that alterations of miRNA expression may contribute to chemosensitivity for anticancer drugs.
