EMILIN1 and neoplasm: Expression analysis showed that these genes were more highly expressed in LUAD tumor tissues compared with normal tissues (Figure 5A) except for EMILIN1 and MMP2. Moreover, COL1A1, COL1A2, COL3A1, COL5A1, COL5A2, THY1 exhibited a more promising outcome in more lowly expressed group (Figure 5B).
