Objective:
To modify the empirical method of precision-cut liver slice technique, and study the hepatotoxicity of monocrotaline by this technique.
Method:
Liver slices were prepared by the domestic shaking slicer. The technique of precision-cut liver slice was established by detecting MTT reduction used as the slice viability under different culture medium, thickness of slices, pH and culture temperature. After monocrotaline and liver slices co-culture for 6, 24 h, the slice viability, enzyme activity of GPT, GOT, LDH, GGT and protein concentration were detected by MTT reduction, enzyme kinetics method and BCA protein assay method, respectively.
Result:
When the thickness of slices was 200 microm and pH of medium was 6.8, culture temperature was 37 degrees C, BPM culture medium, the viability of slices could maintain on a steady level. LDH leakage was significantly increased and protein content was obviously decreased after monocrotaline co-culture for 24 h with final concentration 0.02, 0.1 and 0.5 g x L(-1). No statistically significant difference between control group and monocrotaline 3 dose groups was observed in the slice viability and the content of GPT, GOT, LDH, GGT and protein after monocrotaline co-culture for 6 h.
Conclusion:
The slice viability could retain 24 h in modified BPM medium surroundings; monocrotaline displayed liver toxicity in some degree after co-culture for 24 hours in 0.02, 0.1 and 0.5 g x L(-1) concentration.
Insights
This study optimized the precision-cut liver slice technique to assess monocrotaline's hepatotoxicity. Results show monocrotaline causes liver damage after 24-hour exposure, indicating its toxicity.
Area of Science:
- Hepatology
- Toxicology
- Biotechnology
Context:
- The precision-cut liver slice technique is a valuable tool for studying drug metabolism and toxicity.
- Optimizing this technique enhances its reliability for toxicological assessments.
- Monocrotaline is a known hepatotoxin requiring further investigation into its mechanisms of action.
Purpose:
- To refine the precision-cut liver slice technique for improved hepatotoxicity studies.
- To investigate the hepatotoxic effects of monocrotaline using the optimized technique.
Summary:
- The study established optimal conditions for precision-cut liver slices, including slice thickness (200 microm), pH (6.8), temperature (37°C), and culture medium (BPM).
- Exposure to monocrotaline for 24 hours at concentrations of 0.02, 0.1, and 0.5 g/L significantly increased lactate dehydrogenase (LDH) leakage and decreased protein content, indicating cellular damage.
- No significant toxicity was observed at 6 hours, suggesting a time-dependent effect of monocrotaline.
Impact:
- Provides a refined and validated method for assessing hepatotoxicity using precision-cut liver slices.
- Demonstrates the dose- and time-dependent hepatotoxic effects of monocrotaline.
- Contributes to a better understanding of monocrotaline-induced liver injury and aids in the development of predictive toxicology models.
