Abstract
Matrix metalloproteinases (MMPs) play a key role in cancer
progression, including cell invasion, metastasis, cell growth,
apoptosis, angiogenesis, and cell adhesion. Thus, suppression of the
MMPs activities is crucial for inhibiting cancer cells metastasis. Herein, bioactive agents from crocodile
(Crocodylus siamensis) leukocyte extracts (WBCex) showed the anticancer
activity with HeLa cells and inhibited the migration and invasion
process by reducing gelatinases (MMP-2, MMP-9) activity and their
protein levels. This mechanism is regulated via interfering Ras and p38
signal transduction. Moreover, disrupting VEGF and integrin-signaling
cascade by bioactive agents are the predictable mechanisms that cause
the decreasing of MMP-2 and MMP-9 activity. Hence, bioactive substances
in WBCex may play the mode of action similar with MMPs inhibitor due to
HeLa cell metastasis being suppressed in vitro. © 2015 Wiley
