BMP4 and cancer: As expected, the methylation and expression of BMP4 were adversely correlated in most cancer types, with such correlations being significant only in endometrioid cancer (UCEC), lung squamous cell carcinoma (LUSC), LAML, thymoma (THYM), ocular melanomas (UVM), ACC, uterine carcinosarcoma (UCS), and large B-cell lymphoma (DLBC) (Supplementary Figure S2B).
