The effect mechanism of Ginnalin A as a homeopathic agent on various cancer cell lines

Abstract

Epidemiological and experimental studies have shown that natural products are beneficial for the protection against cancer. Maple syrup is a natural sweetener often consumed throughout the world. Maple syrup contains various phenolic compounds such as lignans, coumarin and Ginnalin A (GA). The aim of this study was to investigate the effects of GA shown to have cytotoxic and apoptotic effects in several human carcinoma cell lines. The effect of GA on cell viability was determined by a XTT (2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) assay as described in the manufacturer's instruction. Total RNA was isolated from cancer cells using TRIzol Reagent and reverse transcription was performed using Script™ cDNA Synthesis Kit (Bio-Rad) according to the manufacturer's instructions. Expressions of important genes in apoptosis including MMP-2, MMP-9, TIMP-1, TIMP-2, CDH1 and CDH2, were investigated in dose and control groups by qPCR (quantitative real time-polymerase chain reaction). When compared with the control group, qPCR results illustrated that a significant increase in gene expression was observed in the expressions of CDH1, TIMP-1 and TIMP-2 by 3.52, 5.13 and 2.67 times respectively. Research has shown that Ginnalin A can demonstrate an anti-metastatic effect by regulating the expression of important genes in metastasis on cancer cell lines. Furthermore, in this study the activation of caspase-8 in apoptotic signaling pathways and the pro-apoptotic caspases required for extrinsic apoptotic signal transduction was defined.
