Since several studies have reported that phosphatases and tensin homolog (PTEN) is an essential tumor suppressor gene which encodes a phosphatase protein that antagonizes the PI3K/AKT/mTOR anti-apoptotic pathway [12, 13], we next examined whether MTE promoted the apoptosis of Jurkat cells through PTEN pathways. This evidence concerns the gene AKT1 and neoplasm.
