Sprague-Dawley (SD) and JCR rats underwent 0 or 9 days of repetitive ischemia (RI), hearts were excised, and the normal zone (NZ) was separated from the collateral-dependent zone (CZ). A: liquid chromatography-mass spectrometry (LC-MS) quantitation of 20-hydroxyeicosatetraenoic acid (20-HETE) production represented in pg/mg protein. B: representative Western blot of CYP4F protein expression (bottom) and cumulative data (top) in NZ and CZ heart homogenates represented in arbitrary units; n = 8, *ξP < 0.05 as indicated.
