Background

Etoposide-induced 2.4 mRNA (EI24)/p53-induced gene 8 (PIG8) was identified as a DNA damage response gene induced by etoposide in a p53 dependent manner with roles in growth suppression and apoptosis (1-3). As a pro-apoptotic gene, some evidence suggests that EI24 functions as a tumor suppressor gene in cases such as breast and cervical cancer (4-6). The mechanism of EI24 is still unclear, but studies have shown that it can localize to the endoplasmic reticulum and associate with Bcl-2 and could regulate apoptosis through regulation of Bcl-2 function (7). Liver-specific deletions of EI24 in mice show impaired autophagic flux, suggesting that it may also play a role in regulating basal autophagy (8). EI24 was shown to be involved in the autophagic degradation of many RING E3 ligases (9). In addition, decreased expression of EI24 in epithelial tumor cells induced epithelial-to-mesenchymal transition (EMT) (10). Together these studies suggest multiple mechanisms for EI24 to regulate tumor progression that includes regulation of apoptosis, autophagy, and EMT.
