Malat1 is implicated in AEC upon DC co-culture. (A) Simple summary of the co-culture system. The expression of Malat1 in AECs was detected by real-time PCR and found to be upregulated in the co-culture system in the presence (B) and absence (C) of LPS. (D) Malat1 knockdown AEC was generated by siRNA transfection, then the transfected AECs were harvested and subjected to q-PCR (n=5, *P<0.05 vs. AEC only group group and ‘NC siRNA’). AEC, airway epithelial cells; DC, dendritic cell; Malat1, metastasis-associated lung adenocarcinoma transcript 1; q-PCR, quantitative polymerase chain reaction; LPS, lipopolysaccharide.
