[Effects of high-fat diet on FABP2 mRNA expression in small intestinal tissue of young rats]
Insights
High-fat diets reduced FABP2 mRNA expression in rat intestines, correlating with increased weight, blood glucose, and triglycerides, suggesting FABP2
Area of Science:
- Molecular Biology
- Nutritional Science
- Metabolic Research
Background:
- Fatty acid-binding protein 2 (FABP2) plays a role in lipid absorption and metabolism.
- Childhood obesity is a growing public health concern with complex underlying mechanisms.
Purpose of the Study:
- To investigate FABP2 mRNA expression in rat small intestines under a high-fat diet.
- To explore the relationship between FABP2 mRNA expression and diet-induced obesity in young rats.
Main Methods:
- Established high-fat diet-induced obesity models in young rats.
- Quantified FABP2 mRNA expression in jejunum and ileum tissues using real-time PCR.
- Assessed serum biochemical parameters, including blood glucose and triglycerides.
Main Results:
- FABP2 mRNA expression varied across intestinal segments (duodenum, jejunum, ileum).
- High-fat diet significantly decreased FABP2 mRNA expression in obese rats compared to controls.
- Obese rats exhibited significantly elevated blood glucose and serum triglyceride levels.
Conclusions:
- FABP2 mRNA expression is segment-specific in the small intestine.
- High-fat feeding reduces intestinal FABP2 mRNA expression, coinciding with weight gain and dyslipidemia.
- FABP2 may be implicated in lipid metabolism and the development of childhood obesity.
Objective:
To measured FABP2 mRNA expression of small intestinal rats in response to high-fat diet; and to explore the correlation between expression and child obesity in rats.
Methods:
The young obese rat models high-fat diet-induced method. Then the expression levels of FABP2 mRNA jejunum and ileum tissues of young rats were detected and analyzed using real time fluorescence quantitative PCR method. The serum biochemical assessed with an automatic biochemical Analyzer.
Results:
In both rnd obesity group, the expression levels of FABP2 mRNA were highest in ermediate in the jejunum, and lowest in the duodenum both the control obesity group, there' were significant differences among them ( P <0. 05). Compated with control group, the expression levels of FABP2 mRNA in obesity group were significantly decreased (P <0.05); and the levels of blood glucose and serum TG in the obesity group were significantly higher (P < 0.05 ).
Conclusion:
FABP2 mRNA expression was different in diverse segments of intestinal tissue. Feeding high-fat diets allowed rats to reduce the expression levels of FABP2 mRNA in small intestinal tissue, meanwhile, the rats gained weight and elevate serum TG levels. It suggests that FABP2 involves in lipid metabolism, and is associated with the development of childhood obesity.
