Depletion of SHROOM2 in nasopharyngeal carcinoma (NPC) cells enhances mesenchymal characteristics and reduces epithelial markers, concomitant with increased motility, enabling the development of invasion and tumor metastasis, which are largely ROCK-independent, as ROCK inhibitor Y-27632 did not cause EMT phenotype; furthermore, combination of ROCK inhibition and SHROOM2 depletion resulted in the most robust increases in cell migration and invasion, indicating that SHROOM2 and ROCK work synergistically rather than epistatic. The gene discussed is SHROOM2; the disease is neoplasm.
