ENC1 (ectodermal-neural cortex 1) is an actin-binding protein that regulates neuronal process formation and neural crest cell differentiation, with emerging significance as an oncogene across multiple cancer types 1. The protein functions through multiple cellular mechanisms, including regulation of the MAPK pathway in lung cancer, where ENC1 knockdown decreases phosphorylation of JNK, ERK, and p38, leading to reduced proliferation, migration, and invasion 2. In breast cancer, ENC1 is controlled by super-enhancers and promotes radio-resistance through activation of the Hippo/YAP1/TAZ pathway, enhancing GLI1, CTGF, and FGF1 expression 3. ENC1 demonstrates significant clinical relevance as a prognostic biomarker, with overexpression correlating with poor outcomes across various cancers and negatively associating with immune cell infiltration 4. Paradoxically, in ovarian cancer, lower ENC1 expression predicts favorable prognosis, and its knockdown increases reactive oxygen species levels while inhibiting malignant behaviors 5. In pituitary adenomas, ENC1 shows subtype-specific patterns, with low expression specifically associated with invasiveness in null cell adenomas but not oncocytomas 6. These findings establish ENC1 as a multifunctional protein with context-dependent roles in cancer progression and potential therapeutic target.
