Further analysis using the UALCAN database showed that MMP9, MMP12, CD36, and FABP4 were over expressed in atherosclerotic tissues, while the expression of MMP9 and MMP12 were up-regulated in NSCLC tissues and the expression of CD36 and FABP4 were down-regulated in NSCLC tissues. The gene discussed is MMP12; the disease is non-small cell lung carcinoma.
