Abstract

Abstract: Metastasis is the major hindrance in the treatment of all cancers, including laryngeal squamous cell carcinoma. Intensive researches are under way to identify the effective natural polyphenols with anti-metastatic ability for cancer treatment. Wheatgrass, an herbal plant has been reported to show anticancer effects. Hence, in this study, we aimed to analyze the anti-metastatic effect of methanol extract of wheatgrass (MEWG). The levels of metastatic marker proteins were determined by western blot. PI3K and AKT levels were determined by real time (RT)-PCR analysis. In silico molecular docking was done to check the interaction of the 14 components (identified by HPLC/GCMS) of MEWG with PI3K and AKT. MEWG effectively decreased the metastatic protein expressions, namely VEGF, MMP-9 and COX-2 and increased TIMP-2. RT-PCR results showed reduced m-RNA levels of both PI3K and AKT when compared to control. Molecular docking studies revealed interaction of most of the identified compounds of the extract with the important residues of PI3K and AKT. These findings indicate that MEWG inhibits metastasis and angiogenesis in Hep-2 cells possibly via PI3K/AKT due to the cumulative effect of polyphenols and other constituent present in extract. The compounds of the extract were also found to be directly involved in inhibition of AKT/PI3K, thus could help to restrain metastasis.
