[Influence of Lactobacillus casei on rat bladder carcinogenesis]
Summary
Lactobacillus casei (L. casei) demonstrated an inhibitory effect on bladder cancer development in rats. Treatment with L. casei reduced tumor formation and malignancy, with longer treatment durations showing greater efficacy.
Area of Science:
- Oncology
- Microbiology
- Gastroenterology
Context:
- Investigating the role of probiotics in cancer prevention.
- Utilizing N-butyl-N (4-hydroxybutyl) nitrosamine (BBN)-induced rat bladder cancer model.
- Assessing the impact of Lactobacillus casei (L. casei) on tumor development.
Purpose:
- To evaluate the inhibitory effect of L. casei on superficial bladder tumors.
- To determine the efficacy of L. casei in a rat bladder cancer model.
- To assess the impact of L. casei treatment duration on tumor inhibition.
Summary:
- Short-term L. casei treatment reduced concanavalin A (Con A) agglutination of incipiently transformed bladder epithelial cells.
- Long-term L. casei treatment significantly decreased bladder weight and tumor volume.
- L. casei treatment, especially longer durations, lowered tumor malignancy and prevented advanced tumor extension (T1b, T2).
Impact:
- L. casei shows potential as a preventative agent against bladder cancer.
- Probiotic intervention may offer a novel strategy for managing or preventing bladder tumors.
- Findings suggest L. casei can modulate early-stage and advanced bladder cancer progression.
