OBJECTIVE: To investigate the role of mitochondria-mediated fatty acid metabolism in proximal tubule cells in renal interstitial fibrosis.

MATERIALS AND METHODS: Intraperitoneal injection of folate was performed to induce renal interstitial fibrosis in mice. Polymerase chain reaction (PCR) was used to detect the expression of cytochrome c oxidase subunit IV (COX4IL) and phosphoenolpyruvate carboxykinase 1 (PCK1) in samples. Electron microscope was used to detect the activity of mitochondria. Serum creatinine and urea nitrogen were chosen as evaluation criteria for renal function. Western-blotting was used to detect protein expression of cells. Immunohistochemistry was used to test renal structure and deposition of collagen.

RESULTS: In renal interstitial fibrosis, mitochondria mediated the dysfunction and the promotion of tubulointerstitial fatty acid metabolism. Besides, it could also reduce renal interstitial fibrosis and alleviate the fatty acid metabolism of tubulointerstitial fibrosis.

CONCLUSIONS: Mitochondrial dysfunction induced fatty acid metabolism is an important factor to promote the progress of renal interstitial fibrosis. Intervention of related targets of fatty acid metabolism is expected to become a new treatment for renal interstitial fibrosis.
