Abstract

Liver cancer, one of the most common malignancies, is the second leading cause of cancer death in the world. The citrus reticulate peel and black tea have been studied for their beneficial health effects. In spite of the many studies have been reported, the underlying molecular mechanisms underlying its health benefits are still not fully understood. In present study, we developed a unique citrus reticulate peel black tea (CRPBT) by combined citrus reticulate peel and black tea and assessed its active ingredients, anti-oxidant and anti-liver cancer effects in vitro. The results suggested that CRPBT exhibited antioxidant capacity and effectively inhibited proliferation and migration of liver cancer cells in a dose- and time- dependent manner. Mechanistically, CRPBT significantly down-regulated phosphorylation of PI3K and AKT, and up-regulated the ratio of Bax/Bcl-2, and suppressed the expression of MMP2/9, N-cadherin and Vimetin proteins in liver cancer cells. Taken together, CRPBT has good effect on inhibiting migration, invasion, proliferation, and inducing apoptosis in liver cancer cells.
