In this AI generated episode of The APS Publications Podcast featuring Function, we will dive into exciting new research that is shaping our understanding of how the body works at its most fundamental level. We spotlight the article “Short-term time-restricted feeding improves metabolic rhythms and liver mitochondrial bioenergetic function in high-fat diet-fed mice,” by Valcin et al. published recently in Function. Across the U.S. and the world, more people are developing fatty liver disease—now often called metabolic dysfunction–associated steatotic liver disease. About one in three adults are affected. What causes it? Often, long-term high-fat diets and disrupted metabolism. Inside the liver, tiny structures called mitochondria—the cell’s power plants—stop working efficiently. When that happens, the liver struggles to burn fat, energy levels drop, inflammation rises, and damage spreads to other organs. But here’s the surprising part: It’s not just what we eat that hurts these mitochondria. It’s when we eat. Ready to learn more? Listen now.

In this podcast, author Arun Jose discusses the recently published article, ‘Lactobacillus Is Associated With Disease in Pulmonary Arterial Hypertension: A Prospective Cohort Study.' The prospective cohort study linked the gut microbiome, gut-derived metabolites, and disease severity in patents with pulmonary arterial hypertension undergoing right heart catheterization. Authors found that the presence of Lactobacillus was associated with less severe disease.

In this podcast, author Daniela Negrini discusses the recently published review, ‘The Thoracic Lymphatic Vasculature: Inter-Organ Strategies to Achieve an Optimal Tissue Function’. The article highlights the important but often overlooked role of vascular lymphatic system and the contribution of lymphatic vasculature to the control of extracellular fluid volume and composition as it applies to the majority of the body tissues.

In this episode of The APS Publications Podcast, featuring AJP-Regulatory, Integrative and Comparative Medicine, author Laura Oller discusses her recent article, "Molecular shifts induced by pseudohypoxia in gray seal blubber: an ex vivo approach." This study explored how blubber regulates responses to chemically induced pseudohypoxia. This study showed a faster, but sustained, increase in molecular markers of hypoxia. It documents downstream molecular responses to those hypoxia-induced changes, revealing important adaptations in mechanisms that induce and sustain the hypoxia response in blubber.

In this podcast, Nguyen Duc Huy Hoang discusses his recently published article, ‘Mechanosensory Silence During Cardiac Stress’. He asks the question, "Why does mechanosensory stress in the heart so often remain perceptually silent?" and hopes his group's new conceptual gating framework, Cardiac Mechanoafferent Silencing Model, will shed some light on the topic and support the prioritization of future experimental and translational investigations.

In this podcast, coauthors Yuan Li and Mingming Liu discuss their recently published article, ‘Functional segregation of pancreatic microcirculation reveals sex-dependent microhemodynamic signatures’. The article used a multi-scale approach to investigate pancreatic microhemodynamics in healthy male and female mice. Authors identified sexual dimorphism in pancreatic microhemodynamics that was restricted to the exocrine compartment, where blood vessels expressed different levels of CD31 and estrogen receptor ERβ. These sex-specific vascular patterns were linked to distinct systemic steroid hormone profiles, leading to fundamentally different mechanisms of blood‑flow regulation in males and females. Overall, the work identified pancreatic microvasculature as a key site where hormonal differences shape sex‑specific organ physiology.
