Definitive Evidence for the Identification and Function of Renin-Expressing Cholinergic Neurons in the Nucleus Ambiguus.

Background: The importance of the brain renin-angiotensin system in cardiovascular function is well accepted. However, not knowing the precise source of renin in the brain has been a limitation toward a complete understanding of how the brain renin-angiotensin system operates.

Methods: Highly sensitive in situ hybridization techniques and conditional knockout mice were used to address the location and function of renin in the brainstem.

Early-life sodium restriction programs autonomic dysfunction and salt sensitivity in male C57BL/6J mice.

Preterm birth increases the risk of cardiometabolic disease in adulthood. Infants born during the second trimester of pregnancy, a critical period of hypothalamic development, are at risk of sodium (Na) depletion due to renal immaturity and large urine Na losses. We previously demonstrated in male mice that Na restriction during the equivalent mouse hypothalamic development period [postnatal day (PD)21-PD42] programs long-term changes in energy balance via increased thermogenic sympathetic nervous activity.

Assessing fecal metaproteomics workflow and small protein recovery using DDA and DIA PASEF mass spectrometry.

This study aims to evaluate the impact of experimental workflow on fecal metaproteomic observations, including the recovery of small and antimicrobial proteins often overlooked in metaproteomic studies. The overarching goal is to provide guidance for optimized metaproteomic experimental design, considering the emerging significance of the gut microbiome in human health, disease, and therapeutic interventions. Mouse feces were utilized as the experimental model.
