The results showed that compared with the Sham group, the expression levels of TGF‐β, MMP2, MMP9, TNF‐α, IL‐1β and IL‐6 were all increased in the TAC group, which was reversed by MAT intervention (compared to the TAC group, Figure 4Q–W). The gene discussed is TGFB1; the disease is persistent truncus arteriosus.
