Gentiopicroside Inhibits Cell Growth and Migration on Cervical Cancer via the Reciprocal MAPK/Akt Signaling Pathways

Abstract

Cervical cancer (CC) is a common gynecological malignancy and represents a major global health challenge. Chemotherapeutic agents are commonly applied in treatment of CC, while along various adverse effects and chemotherapy resistance. As an iridoid glycoside compound, gentiopicroside (GPS) possesses the characteristic of the better availability and lower toxicity effect on cancer treatment. In the present study, we investigated that GPS exhibited the anticancer effect on HeLa cells through the inhibition of cell growth, induced apoptosis, cycle arrest, and suppressed migration. Furthermore, the possible mechanism or the targets of GPS was also clarified. The results revealed that GPS exerted an anti-proliferation effect in a dose- and time-dependent manner in HeLa cells, in contrast, with the less inhibiting proliferation effects on normal cell line (HUVEC). Moreover, GPS arrested cells at G2/M phase and induced apoptosis through mitochondrial apoptotic pathway. More significantly, GPS dramatically inhibited the migration of HeLa cells and regulated the matrix metalloproteinase expression through the MAPK and Akt signaling pathways, of which MAPK1 was an underlying target in GPS against HeLa cells.
