Elafibranor upregulates the EMT-inducer S100A4 via PPARβ/δ by Meijian Zhang, Emma Barroso, Maria Ruart, Lucía Peña, Mona Peyman, David Aguilar-Recarte, Marta Montori-Grau, Patricia Rada, Clara Cugat, Carla Montironi, Mohammad Zarei, Javier Jurado-Aguilar, Antoni Camins, Jesús Balsinde, Ángela M. Valverde, Walter Wahli, Xavier Palomer, Manuel Vázquez-Carrera

“…Our findings revealed that elafibranor treatment ameliorated steatosis, inflammation, and fibrogenesis in the livers of CD-HFD-fed mice. Unexpectedly, elafibranor also increased the levels of the epithelial-mesenchymal transition (EMT)-promoting protein S100A4 via PPARβ/δ activation. …”

Relationship between hepatic CTGF expression and routine blood tests at the time of liver transplantation for biliary atresia: hope or hype for a biomarker of hepatic fibrosis by Haafiz A, Farrington C, Andres J, Islam S

“…Further work is required to determine more reliable ways of noninvasive diagnosis of HF.Keyword: connective tissue growth factor, liver fibrosis, blood tests, fibrogenesis…”
