Abstract
Cryptotanshinone (CT), one major lipophilic component isolated from Salvia miltiorrhiza Bunge, has shown to possess chemopreventive properties against various types of cancer cells. In this study, CT was shown to be a potent anti-angiogenic agent in zebrafish, and mouse models and could limit tumor growth by inhibiting tumor angiogenesis. We further found that CT could inhibit the proliferation, migration, angiogenic sprouting, and tube formation of HUVECs. In addition, we demonstrated that CT could lower the level of TNF-α due to the destabilization of TNF-α mRNA, which associated with regulating 3'-untranslated region (3'-UTR) of TNF-α and preventing the translocation of RNA binding protein, HuR, from the nucleus to the cytoplasm. Moreover, the underlying mechanism responsible for the regulation in angiogenesis by CT was partially related to the suppression of NF-κB, and STAT3 activity. Based on the abilities of CT in targeting tumor cells, inhibiting angiogenesis, and destroying tumor vasculature, CT is worthy of further investigation for preventive, and therapeutic purposes in cancer. © 2015 Wiley Periodicals, Inc.
