| Sumario: | Xiaoli Li,1 Xiaoyong Ren,2 Jianmin Liang,2 Weijun Ma,2 Zhenghui Wang,2 Zhuangqun Yang3 1Department of Dermatology, The Second Affiliated Hospital, Xi’an Jiaotong University, Xi’an, People’s Republic of China; 2Department of Otolaryngology-Head and Neck Surgery, The Second Affiliated Hospital, Xi’an Jiaotong University, Xi’an, People’s Republic of China; 3Department of Plastic and Burns Surgery, The First Affiliated Hospital, Xi’an Jiaotong University, Xi’an, People’s Republic of China Abstract: Hemangioma is a common benign tumor affecting infants. In this study, we prepared sodium morrhuate immunoliposomes through encapsulation of sodium morrhuate with liposomes coupled with an anti-VEGFR2/KDR antibody and examined its effect on the biology of human hemangioma endothelial cells (HECs). It was found that compared to the liposomal sodium morrhuate group, treatment with sodium morrhuate immunoliposomes facilitated cell detachment and apoptotic death. Confocal microscopy analysis revealed that sodium morrhuate immunoliposomes had a higher binding activity to HECs than liposomal sodium morrhuate. Apoptosis analysis further demonstrated that treatment with liposomal sodium morrhuate or sodium morrhuate immunoliposomes significantly induced apoptosis in HECs, compared to the control group. Western blot analysis revealed an induction of caspase-3 and caspase-9 levels and reduction of caspase-8 and Bcl-2 levels in HECs treated with liposomal sodium morrhuate or sodium morrhuate immunoliposomes. Taken together, these results indicate that sodium morrhuate immunoliposomes have an increased capacity to target HECs and promote mitochondrial apoptosis. Therefore, sodium morrhuate immunoliposomes may represent a promising agent in the treatment of hemangiomas. Keywords: liposome, hemangioma, VEGF2, KDR, apoptosis |
