Aberrant AKT and extracellular signal-regulated kinase (ERK) activation is often
observed in various human cancers. Both AKT and ERK are important in the
phosphoinositide 3-kinase/AKT and mitogen-activated protein kinase kinase/ERK
signaling pathways, which play vital roles in cell proliferation, differentiation
and survival. Compounds that are able to block these pathways have therefore a
promising use in cancer treatment and prevention. The present study revealed that
AKT and ERK are activated in esophageal cancer TE1 cells. Aloe-emodin, an
anthraquinone present in aloe latex, can suppress TE1 cell proliferation and
anchor-independent cell growth. Aloe-emodin can also reduce the number of TE1
cells in S phase. Protein analysis indicated that aloe-emodin inhibits the
phosphorylation of AKT and ERK in a dose-dependent manner. Overall, the present
data indicate that aloe-emodin can suppress TE1 cell growth by inhibiting AKT and
ERK phosphorylation, and suggest its clinical use for cancer therapy.
