Table 1 Showing cell signalling pathways targeted by different flavonoids. Shows the effect of flavonoids observed in various cell signalling pathways. The activation of ERK, Akt/PKB, PI3K, and PKC is important to improve the cell survival, and the down-regulation of P38 and JNK is preventing the apoptosis. The activation of signalling pathways is shown as up arrow (↑) and down-regulation of signalling pathways by flavonoids is shown in down arrow (↓)
