Autophagy Attenuates Renal Allograft Interstitial Fibrosis by Regulating the EndMT Induced by TNF-α
Z. Gui, C. Suo, Z. Wang, S. Fei, Z. Han, J. Tao, H. Chen, L. Sun, X. Ju, R. Tan, M. Gu
Jiangsu Province Hospital, Nanjing, China
*Purpose: Kidney interstitial fibrosis is a significant cause of allograft failure in kidney transplantation. Autophagy is a self-digestive process that eliminates impaired or aged proteins…

Src Induces Endothelial-to-Mesenchymal Transition and Renal Allograft Fibrosis via Promoting WNT/β-catenin Pathway
W. Zijie, Z. Gui, M. Zheng, Z. Han, J. Tao, H. Chen, L. Sun, X. Ju, R. Tan, M. Gu
Jiangsu Province Hospital, Nanjing, China
*Purpose: Endothelial-to-mesenchymal(EndMT)is recognized as an important source of myofibroblasts contributing to the pathogenesis of allograft interstitial fibrosis in our previous studies. Increased proto-oncogene tyrosine-protein kinase…
