Atractylodin Suppresses Smad-Independent Pathway Activation in A549 Cells 2.five. Atractylodin Suppresses Smad-Independent Pathway Activation in A549 CellsNext, we wanted to clarify the impact of atractylodin around the Smad-independent pathNext, we wanted to clarify the effect of atractylodin around the Smad-independent pathway,which includes the MAPK and PI3K/AKT cascades [18]. Initially, A549 cells were stimuway, which includes the MAPK and PI3K/AKT cascades [18]. Initially, A549 cells were stimulated by TGF-1, and, using Western blot analysis, the levels of phosphorylated p38, JNK, lated by TGF-1, and, utilizing Western blot analysis, the levels of phosphorylated p38, JNK, ERK, and ERK, and AKT had been significantly increased (Figure 5A). Following atractylodin therapy, there were drastically increased (Figure 5A). Soon after atractylodin remedy, was was an obvious decrease phosphorylation of p38 of p38 and JNK, implying that atthere an obvious reduce inside the inside the phosphorylation and JNK, implying that atractylodin could also suppress the expression of S.
