Abstract
This study investigated the renoprotective action of linagliptin compared to doxorubicin against thioacetamide (TAA) and diethyl nitrosamine (DEN)-induced renocarcinogenesis in a rat model. Male Wistar rats were divided into control, renocarcinogenesis (RCC), doxorubicin group (7.5 mg/kg, i.p., once weekly), and linagliptin (Lina) groups (3 and 6 mg/kg/day, p.o.). The experiment included renal function parameters, oxidative stress markers, and predominant molecular pathways involved in renal pathogenesis. The RCC model significantly impaired renal function, as reflected in elevated serum levels of urea and creatinine. It also resulted in elevated oxidative stress, as reflected in increased malondialdehyde (MDA) content and decreased glutathione and superoxide dismutase (GSH and SOD) activities. The model disrupted several molecular pathways, including the AMP-activated protein kinase (AMPK) pathway, and enhanced oncogenic and inflammatory markers such as Yes-associated protein/ Transcriptional coactivator with PDZ-binding motif/ Hypoxia-inducible factor 1-alpha (YAP/TAZ/ HIF-1α), nuclear factor erythroid 2-related factor 2/ Sirtuin 1(Nrf2/SIRT1), and signal transducer and activator of transcription 3 (STAT3). Treatment with linagliptin, particularly the high dose (6 mg/kg/day), was found to be superior to doxorubicin treatment in terms of correction of renal function and markers of oxidative stress. Linagliptin effectively regulated the AMPK pathway, reduced markers of inflammation, restored the expression of genes with key roles in renal protection, reduced proliferating Cell Nuclear Antigen (PCNA), and elevated Caspase-3. The high dose of linagliptin exhibited superior results in most of the parameters, which approached control levels more than those with the lower dose and doxorubicin. These findings demonstrate that linagliptin, especially at 6 mg/kg/day, exhibits significant renoprotective activities through multifarious mechanisms involving antioxidant action and regulation of key molecular pathways. The present study presents evidence for the potential therapeutic application of linagliptin in renal manifestations of renocarcinogenesis.
