Two effects of the citrus methoxyflavone tangeretin on cell-cell interactions are biologically relevant. Firstly, tangeretin upregulates the function of the E-cadherin/catenin complex in human MCF-7/6 breast carcinoma cells. This leads to firm cell-cell adhesion and inhibition of invasion in vitro.

Polymethoxylated flavones (PMFs) are found in the peel tissues of some citrus species. Here, we report that PMFs, such as nobiletin, potentiate the cytolytic activity of KHYG-1 natural killer (NK) leukemia cells. Nobiletin markedly enhanced the expression of granzyme B
