This study investigated the molecular validity of the precision-cut kidney slice (PCKS) model.
The PCKS model demonstrated significant p-Smad2 and p-Smad3 upregulation relative to control.
The model showed higher Smad2/3 complex formation and nuclear translocation relative to control.
The model showed significant p-ERK1, p-ERK2, and p-p38 MAPK upregulation relative to control.
The PCKS model displays several well-established molecular markers of renal fibrosis.
