IER3: exploring its dual function as an oncogene and tumor suppressor.

ABSTRACT: The IER3 gene has a complex role in cancer biology, acting either as a tumor suppressor or an oncogene, depending on the cancer type. This duality underscores the complexity and importance of molecular pathways in modulating cancer behavior. Despite its significance in cancer development, there is a dearth of studies elucidating the exact mechanisms underlying IER3's involvement in modulating cancer behavior. Here, utilizing cervical carcinoma and neuroblastoma (NB) cell lines as model systems we characterized the pathways that mediate the functional switch between the oncogenic and tumor suppressor roles of IER3. In HeLa cells, IER3 expression promotes an oncogenic program that includes immediate early response pathway genes such as EGR2, FOS, and JUN. However, in NB cells, IER3 suppresse
