To explore the regulation of CCT6A in the pathogenesis of lung fibrosis in vivo, we subjected adeno-associated virus serotype 2/9 (AAV2/9), either pcAAV-CMV-Cct6a-Flag or pcAAV-CMV to C57BL/6N mice via intratracheal delivery, and then intratracheal BLM or saline to the mice a week later (Figure 6A). This evidence concerns the gene CCT6A and pulmonary fibrosis.
