Efficient therapeutic combinations of a naturally occurring trans-ferulic acid with different chemotherapies on in vitro hepatocellular carcinoma

Abstract Trans- ferulic acid (TFA) is a polyphenolic compound present in many dietary supplements. To get better chemotherapeutic outcomes through treatment protocols for human hepatocellular carcinoma (HCC). This study focused on the exploration of the in vitro influence of a combination of TFA with 5-fluorouracil (5-FU), doxorubicin (DOXO), and cisplatin (CIS) on HepG2 cell line. Treatment with 5-FU, DOXO, and CIS alone down-regulated oxidative stress, alfa-fetoprotein (AFP), and decreased cell migration through the depression of metalloproteinases (MMP-3, MMP-9, and MMP-12) expression. Co-treatment with TFA synergized the effects of these chemotherapies by decreased MMP-3, MMP-9, and MMP-12 expression, and gelatinolytic activity of both MMP-9 and MMP-2 in cancer cells. TFA significantly reduced the elevated levels of AFP and NO, and depressed cell migration ability (metastasis) in HepG2 groups. Co-treatment with TFA elevated the chemotherapeutic potency of 5-FU, DOXO, and CIS in managing HCC.
