MYO1B and lip and oral cavity carcinoma: MYO1B overexpression has been linked to lymph node metastases and poor outcomes in oral cancer. MYO1B was found to have a positive correlation with macrophage, B cell, and dendritic cell infiltration. Suppression of MYO1B inhibit the ability of Arecoline‐transformed oral cells and oral cancer cells to proliferate, invade, and metastasize.
