MFSD2A and non-small cell lung carcinoma: Measurement of MFSD2A mRNA levels in NSCLC cell lines and normal human bronchial epithelial cell (HBEC) lines (Additional file 1), normalizing the data to the average expression of HBECs, revealed downregulation of MFSD2A (2- to 44-fold) in 33/47 (70%) NSCLC cell lines but only in 4/20 (20%) HBEC lines (Fig. 1B).
