Furthermore, a microarray study by Pak et al. investigated three alternately expressed miRNAs, including the tumor suppressor miR-34c, and oncogenes miR-183, and miR-210 in wild type and EGFR-mutated LADC (in exons 19 and 21), where miR-183 expression was notably higher in EGFR-mutated tissues than in wild-type tissues and positively correlated with lymphovascular invasion. The gene discussed is EGFR; the disease is neoplasm.
