Regulation of vascular smooth muscle cell autophagy by DNA nanotube-conjugated mTOR siRNA.

abstract：:Chemotherapeutic agents often cause severe side effects because they produce a similar cytotoxicity in both cancerous and healthy cells. In this study, a rational strategy was implemented to take advantage of a combination of both tumor microenvironment-sensitive polypeptides (TMSP) and folate to create a more selecti...
