Abstract:
The current study was carried out to evaluate the protective effect of grape seed proanthocyanidins extract (GSPE) against Ehrlich solid tumor (EST) induced renal injury, with the respect to DNA fragmentation and P53 and PCNA proteins expression in renal tissue. A total of 50 female mice were randomly assigned into five groups. Control mice were injected with physiological saline solution. Mice of the 2nd group were administered with GSPE (50 mg/kg bw/every 2day/per OS) for 2 weeks and injected with physiological saline solution. Mice of the 3rd group were injected subcutaneously with 2.5 million cells of EAC/mouse. Mice of the 4th group were injected with EAC as the 3rd group and administered with GSPE as the 2nd group simultaneously for 2 weeks. Mice of the 5th group were injected with EAC as the 3rd group and left for 2 weeks (till development of solid tumor), then treated with GSPE for another 2 weeks. EST significantly increased serum levels of urea, creatinine, potassium and chloride. In addition, it induced renal tissue and DNA injuries and increased P53, PCNA and ki67 proteins expression in renal tissues. On the other hand, it decreased serum levels of sodium and calcium ions. However, treatment of EST bearing mice with GSPE normalized serum levels of the above-mentioned parameters and improved renal tissue structure and reduced renal tissue DNA damage and P53, PCNA and ki67 proteins expression. These results indicated that GSPE is a promising nephron protective agent against EST induced renal injury.
Insights
Grape seed proanthocyanidins extract (GSPE) protects kidneys from Ehrlich solid tumor (EST) induced injury. GSPE treatment normalized kidney function and reduced DNA damage and protein expression in renal tissues.
Area of Science:
- Biochemistry
- Toxicology
- Pharmacology
Background:
- Ehrlich solid tumor (EST) can induce significant renal injury.
- Assessing the protective effects of natural compounds against drug-induced or disease-induced organ damage is crucial.
Purpose of the Study:
- To evaluate the protective effect of grape seed proanthocyanidins extract (GSPE) against Ehrlich solid tumor (EST) induced renal injury.
- To investigate the impact of GSPE on DNA fragmentation and P53, PCNA, and ki67 protein expression in renal tissue.
Main Methods:
- 50 female mice were divided into five groups: control, GSPE-treated, EST-induced, EST + GSPE (simultaneous treatment), and EST + GSPE (delayed treatment).
- Renal injury was assessed by measuring serum urea, creatinine, potassium, sodium, and calcium levels.
- Renal tissue and DNA integrity were evaluated, along with the expression of P53, PCNA, and ki67 proteins.
Main Results:
- EST significantly elevated serum urea, creatinine, potassium, and chloride, while decreasing sodium and calcium.
- EST induced renal tissue damage, DNA fragmentation, and increased P53, PCNA, and ki67 expression.
- GSPE treatment normalized serum electrolyte and kidney function markers, improved renal tissue structure, and reduced DNA damage and protein overexpression.
Conclusions:
- Grape seed proanthocyanidins extract (GSPE) demonstrates significant nephron protective properties against Ehrlich solid tumor (EST) induced renal injury.
- GSPE mitigates renal damage by reducing DNA fragmentation and modulating the expression of key proteins involved in cell proliferation and apoptosis.
