Abstract

Podocyte injury is considered a major contributor to the development of diabetic nephropathy (DN). Therefore, identification of potential therapeutic targets for preventing podocyte injury has clinical importance. Recent studies have indicated that autophagy is a key homeostatic mechanism to maintaining podocyte integrity and function. This study was to elucidate the role of progranulin (PGRN), a secreted glycoprotein, in the modulation of podocyte autophagic process and podocyte injury under a diabetic condition. PGRN was downregulated in the kidney from diabetic mice and podocytes under a high-glucose (HG) condition. PGRN deficiency exacerbated the renal dysfunction and glomerular structural alterations. In vitro, treatment with recombinant human PGRN (rPGRN) attenuated HG-induced podocyte injury accompanied by enhanced autophagy. Inhibition of autophagy disturbed the protective effects of PGRN in HG-induced podocytotoxicity. Furthermore, PGRN induced autophagy via the PGRN-CAMKK-AMPK pathway. Collectively, our data identified the protective role of PGRN in podocyte injury via restoring autophagy and activating the CAMKK-AMPK pathway, which may pave the road to new therapeutic modalities for the treatment of diabetic nephropathy.

Key messages

• PGRN level is reduced in kidney of diabetic mice and high-glucose–treated podocytes.

• PGRN deficiency exacerbates renal injury in diabetic mice.

• PGRN protects against high-glucose–induced podocyte injury.

• PGRN restores high-glucose–inhibited autophagy in podocytes.

• CAMKK-AMPK pathway is required for the protective role of PGRN in podocyte injury.
