In association of miRNAs expression with the immunohistochemical expression of EGFR, we observed positive association between expression of miR-133b and let-7a and reactivity of EGFR. Let-7a has been already implicated in tumourigenesis and similarly as in MECs, ACCCs, and poorly differentiated carcinoma of salivary glands it has been shown to be reduced in lung cancer. Here, EGFR is linked to lung cancer.
