Technical Articles

This article focuses on the molecular characteristics and biological functions of Activin A, systematically elaborating its molecular mechanism as a core member of the TGF-β superfamily in activating the SMAD2/3 signaling pathway through activin receptors, analyzing the multiple functions of Activin A in embryonic development, reproductive regulation, muscle homeostasis, inflammatory responses, and tumorigenesis, and exploring the application strategies of Activin A recombinant protein in cell differentiation research, disease model construction, and drug development.
