Suppression of growth of Hela, EJ, SK-OV-3 and MDA-MB-231 cells by recombinant human NK4

Abstract

To study the effects of recombinant human Nk4 on the growth and invasion activities of tumor cells. The inhibition of recombinant human NK4 on human oophoroma, cervical tumor, breast tumor and gallbladder tumor cells was evaluated in vitro by basement membrane invasion assay. rhNK4 could markedly inhibited the growth of human oophoroma, cervical tumor and breast tumor cells. The inhibition rates of human oophoroma, cervical tumor, breast tumor and gallbladder tumor cells were 48.2%, 29.2%, 58.4% and 30.1% respectively. rhNK4 factor can markedly inhibit the invasion of multiple tumor cells.
