Periodontitis-induced colonic inflammation in mice

Validation Score: 0.900 Price: $0.50 Periodontitis and intestinal inflammation C57BL/6J mice Status: proposed

What This Experiment Tests

Validation experiment designed to validate causal mechanisms targeting GPR109A in C57BL/6J mice. Primary outcome: Colonic GPR109A expression and intestinal barrier integrity

Description

This experiment investigated the effects of ligature-induced periodontitis on intestinal inflammation and barrier function in mice. C57BL/6J mice were subjected to periodontal ligature placement under normal chow or high-fructose diet conditions. The study evaluated periodontal destruction using micro-CT and histological analysis, then assessed downstream effects on colonic GPR109A expression, intestinal epithelial integrity, and both local and systemic inflammatory responses. Multiple analytical techniques were employed including histology, immunostaining, qPCR, ELISA, and GC-MS/MS for short-chain fatty acid quantification. The experiment aimed to establish a mechanistic link between periodontitis and gut inflammation through microbiota-mediated pathways.

Protocol

Ligature-induced periodontitis in mice, followed by micro-CT analysis, histological evaluation, qPCR, immunostaining, ELISA, and GC-MS/MS analysis of colonic contents

Expected Outcomes

Periodontitis would downregulate GPR109A expression and disrupt intestinal barrier function

Success Criteria

Significant changes in GPR109A expression, tight junction protein localization, and inflammatory markers
