WebbImmunohistochemistry was performed to determine the expression of Smad transducer proteins in NFPAs. Ki-67 was evaluated as an indicator of the proliferative activity of NFPAs. Results: A total of 161 patients with NFPAs were identified; 59 (36.6%) had invasive NFPAs and 102 (63.4%) had noninvasive NFPAs. WebbEmerging evidence shows that TGF-β/ALK/Smad signaling plays a role in carcinogenesis in many cancer types. 24–26 TGF-β signaling is reported to facilitate tumor growth and metastasis in advanced cancer, and blocking TGF-β/ALK/Smad signaling could suppress the process of epithelial-to-mesenchymal transition. 27 Geng et al 28 demonstrated that …
