Background The PI3K-Akt signal pathway plays a key role in tumorigenesis and the development of drug-resistance. relocation in sensitive breast tumor cells. Induction of FOXO3a activity in doxorubicin-sensitive MCF-7 cells was adequate to promote Akt phosphorylation and police arrest cell expansion. Conversely, knockdown of endogenous FOXO3a appearance reduced PI3E/Akt activity. Using MDA-MB-231 cells, in which… Continue reading Background The PI3K-Akt signal pathway plays a key role in tumorigenesis
