This preclinical study measured the expression of gut-derived peptide hormone receptors in the developing mouse hypothalamus from postnatal days 7 to 21. It found dynamic changes in receptor protein levels, with GIPR expression decreasing rapidly and correlating negatively with body weight.
The study used C57BL6/N mice to investigate the expression of gut-derived peptide hormone receptors (GIPR, GLP1R, CCK2R) in hypothalamic tissue across postnatal development (days 7-21). Methods included qPCR and Western blot analyses, with correlations to body weight, blood glucose, and leptin. Key results showed dynamic protein regulation of these receptors during early postnatal life. GIPR and InsR protein levels showed a strong negative correlation with body weight. The authors discuss potential sex-specific differences in receptor expression and suggest these receptors may play roles in forming neuronal circuitry, referencing parallels to human brain development. Limitations include the use of a mouse model and the need for further studies on subnuclear expression and activity regulation.
