چکیده انگلیسی
Adipogenesis is characterized by early remodeling of the extracellular matrix, allowing preadipocytes to adopt a more spherical shape and optimize lipid accumulation as they mature. Aortic carboxypeptidase-like protein (ACLP), found in collagen-rich tissues including adipose tissue, is expressed in 3T3-L1 and 3T3-F442A preadipocytes, and is downregulated during adipogenesis. We now report that ACLP is found in medium conditioned by 3T3-L1 preadipocytes. Transforming growth factor (TGF) β, a known modulator of fibrillar matrix protein production, increased ACLP expression by 2.4 ± 0.4-fold (mean ± SE; n = 3) in 3T3-L1 preadipocytes, through a mechanism that requires p42/44 MAPK activity. Addition of TGFβ to differentiation medium, which inhibits adipogenesis, raised ACLP levels in 3T3-L1 cells. However, sustained expression of ACLP in stable clones of 3T3-L1 or 3T3-F442A preadipocytes did not interfere with adipogenesis.
