Objective:
Molecular mechanisms of nephrosclerosis caused by hypertension are not well known. Understanding changes in renal protein expression in hypertension may provide further information on how hypertension caused renal injury.
Methods And Results:
In the present study, we showed the protein expression profiles of the kidney in spontaneously hypertensive rats and Wistar-Kyoto rats using two-dimensional gel electrophoresis (2-DE). Differentially expressed protein spots were excised, underwent in-gel tryptic digestion, and were analyzed by MALDI-TOF MS. Eleven spots were identified. Of these identified spots, four spots were newly appeared, five spots up-regulated, and two spots down-regulated. The identified spots were mainly involved in energy metabolism, lipid transferring between membranes, and cell proliferation.
Conclusions:
The expression of many proteins have changed significantly in the kidney of spontaneously hypertensive rat. NADP(+)-dependent isocitrate dehydrogenase may be a candidate for further investigation of pathophysiological mechanisms of renal injury in hypertension.
