Kidney lysates were prepared and Western blots performed as previously described19 (link). Quantification of Western Blots was by densitometry with analysis using Image J software20 (link). The following antibodies were used in the Western Blot analysis: anti-α-Smooth Muscle Actin—FITC antibody (Sigma-Aldrich, St. Louis, USA), anti-Fluorescein-POD Fab fragments (from goat Roche Applied Science, Indianapolis, USA), anti-GAPDH antibody (Rabbit monoclonal antibody, Cell Signaling technology, Massachusetts, USA), anti-Fibronectin antibody (Rabbit monoclonal antibody, Sigma-Aldrich, St.Louis, USA), anti-phospho-PFKFB2 (Ser485) (Rabbit monoclonal antibody, Cell Signaling Technology, Massachusetts, USA), anti-PFKFB2 antibody (Rabbit polyclonal antibody, abcam, Cambridge, UK), anti-PKM2 antibody (Rabbit monoclonal, Cell Signaling technology, Massachusetts, USA), anti-pPKM2 antibody (Rabbit polyclonal, Cell Signaling technology, Massachusetts, USA) and anti-rabbit Immunoglobulin HRP-linked (Swine polyclonal, Dako, Agilent Pathology Solutions, Santa Clara, USA).
