Abstract:
Arsenic can induce lethal hepatorenal insufficiency by inducing progressive cytotoxicity in the two main body's hemostatic regulators, the kidney and liver. In the current study, the hepatorenal protective impact of caffeic acid was investigated in arsenic-exposed Syrian mice. Twenty-four male Syrian mice (30 8 g) were provided and randomly divided into 4 groups of 6 receiving nothing, arsenic, arsenic and caffeic, and caffeic acid. The mice passed the 21-day treatment program. The mice's blood was collected and analyzed by measuring the serum ALT/AST enzymes and creatinine/urea levels, respectively. Finally, the histopathological properties in both the kidney and liver organs of the mice were studied. Arsenic administration significantly increased aspartate aminotransferase (AST), alanine aminotransferase (ALT), LDH, urea, and creatinine concentrations (p < 0.05). Simultaneous administration of caffeic acid with arsenic decreased the serum AST and creatinine (p < 0.05). Moreover, the renal glomerulus and liver regeneration in the mice receiving caffeic acid supplements exhibited the caffeic acid hepatorenal protective potential. The histopathological changes caused by arsenic in the mice's liver and kidney tissue including degeneration, necrosis, hyperemia, and tissue hypotrophy were shifted to normal conditions following the caffeic acid administration dose, which was verified by the mice blood biochemical analysis results.
Insights
Caffeic acid protects against arsenic-induced liver and kidney damage in mice. This study shows that caffeic acid can reduce toxic effects and promote organ regeneration, offering potential therapeutic benefits.
Area of Science:
- Toxicology
- Hepatology
- Nephrology
- Natural Product Chemistry
Background:
- Arsenic exposure is a significant global health concern, leading to severe hepatorenal insufficiency.
- Cytotoxicity in the liver and kidneys is a primary mechanism of arsenic toxicity.
- Identifying protective agents against arsenic-induced organ damage is crucial for public health.
Purpose of the Study:
- To investigate the hepatorenal protective effects of caffeic acid against arsenic toxicity in a mouse model.
- To evaluate the biochemical and histopathological changes in liver and kidney tissues following arsenic exposure and caffeic acid treatment.
Main Methods:
- Twenty-four male Syrian mice were randomly assigned to four groups: control, arsenic-only, arsenic + caffeic acid, and caffeic acid-only.
- Mice were treated for 21 days, followed by blood collection for serum analysis of liver enzymes (ALT, AST) and kidney function markers (creatinine, urea).
- Histopathological examination of liver and kidney tissues was performed to assess cellular damage and regeneration.
Main Results:
- Arsenic administration significantly elevated serum levels of AST, ALT, LDH, urea, and creatinine compared to the control group (p < 0.05).
- Co-administration of caffeic acid with arsenic significantly reduced serum AST and creatinine levels (p < 0.05).
- Histopathological analysis revealed that caffeic acid mitigated arsenic-induced degeneration, necrosis, hyperemia, and hypotrophy in liver and kidney tissues, promoting regeneration.
Conclusions:
- Caffeic acid demonstrates significant hepatorenal protective potential against arsenic-induced toxicity in mice.
- The protective effects are evidenced by normalized biochemical markers and improved histopathological conditions of the liver and kidneys.
- Caffeic acid may serve as a potential therapeutic agent for mitigating arsenic poisoning.
