MMP7 and idiopathic pulmonary fibrosis: We also found that the upregulated TE expression in the intron (chr14|22,843,913|22,844,208|AluSx1:Alu:SINE), and in the 3‘UTR region (chr11|102,520,549|102,520,704|L2c:L2:LINE) significantly correlates with two upregulated matrix metalloproteases (MMP14 and MMP7, respectively) in IPF group (Supplemental Table 6B).
