EGFL7 and Familial prostate cancer: To further investigate whether miR-126 and EGFL7 were concomitantly expressed in NSCLC as previously described for prostate cancer (17) and malignant pleural mesothelioma (16), we performed spearman’s correlation analysis to detect the correlation of miR-126 and EGFL7 expression in both NSCLC tissues and adjacent normal tissues.
