Oxyresveratrol and/or Dapagliflozin Attenuate Doxorubicin-Induced Nephrotoxicity via Modulation of PPAR-γ/Nrf-2/HO-1, NF-κB/TNF-α/Keap-1, and Bcl-2/Caspase-3/ATG-5 signaling pathways in rats.

Abstract

Purpose: Among the most undesirable effects that lead to the restriction of doxorubicin (DOX) use in chemotherapy is kidney damage. This research aimed to assess the possible defenses against DOX-induced nephrotoxicity offered by oxyresveratrol (ORES) and/or dapagliflozin (DAPA).

Methods: Five groups of eight male Swiss albino rats each were created from a total of sixty-four. One intravenous injection of DOX (10 mg/kg) was given into the tail vein on the fourteenth day of the experiment; in the meantime, ORES (80 mg/kg) and DAPA (10 mg/kg) were given orally 14 days prior to the DOX injection and 2 days following the DOX injection.

Results: In rats given DOX, ORES and/or DAPA both successfully reduced the kidney weight, kidney/bodyweight ratio, and blood levels of creatinine, uric acid, and urea. They also increased final body weight and albumin serum levels. Additionally, lower serum concentrations of TNF-α and IL-6 were noted, along with a lower kidney content of caspase-3. Furthermore, the expression of the Bcl-2 gene was upregulated, as were the Nrf-2, PPAR-γ, and HO-1 proteins, and there was a downregulation of the ATG-5, Keap-1, and NF-κB renal gene expression. These findings support a decrease in oxidative stress and relief of histopathological alterations.

Conclusion: The current study's findings suggest that ORES and/or DAPA pretreatment could be a viable therapeutic approach to ameliorate DOX-induced nephrotoxicity.
