Gap junction-mediated intercellular communication (GJIC) is essential for the proper function of many organs, including the lens. GJIC in lens epithelial cells is increased by FGF in a concentration-dependent process that has been linked to the intralenticular gradient of GJIC required for lens transparency. Unlike FGF, elevated levels of TGF-beta are associated with lens dysfunction. We show t...

Recent studies have shown that myostatin, first identified as a negative regulator of skeletal muscle growth, may also be involved in the formation of fibrosis within skeletal muscle. In this study, we further explored the potential role of myostatin in skeletal muscle fibrosis, as well as its interaction with both transforming growth factor-beta1 and decorin. We discovered that myostatin stimu...

Transforming growth factor beta1 (TGF-beta1) is a cardinal cytokine in the pathogenesis of airway remodeling, and promotes epithelial-to-mesenchymal transition (EMT). As a molecular interaction between TGF-beta1 and Jun N-terminal kinase (JNK) has been demonstrated, the goal of this study was to elucidate whether JNK plays a role in TGF-beta1-induced EMT. Primary cultures of mouse tracheal epit...

OBJECTIVE Overexpression of transforming growth factor-beta 2 has been associated with craniosynostosis and resynostosis following surgery. We examined the effects of localized transforming growth factor-beta 2 inhibition on craniofacial phenotype in rabbits with craniosynostosis. DESIGN Twenty-five New Zealand white rabbits with bilateral coronal craniosynostosis were divided into three trea...
