Shown as Figure 1e, MARVELD1 level was significantly down-regulated in lung cancer cell line A549, NCI-H727, SK-MES-1, NCI-H460, NCI-H1299, NCI-H69, NCI-H82, LTEP-α-2, 95C, 95D, NCI-H661, SPC-a1, GLC-82, QG56, L18, AGZY-83a and Anip973, slightly down-regulated in NCI-H520, and not altered significantly in NCI-H292 compared to MRC-5 cells. Here, MARVELD1 is linked to lung cancer.
