Physiology explores how living systems function, from the microscopic signals inside a single cell to the complex rhythms of an entire organism. This field seeks to understand the mechanical, physical, and biochemical processes that keep life moving, offering crucial insights into health, disease, and the body's remarkable ability to adapt.

On Gist.Science, we process every new preprint in this category from bioRxiv to make these rapid discoveries accessible to everyone. For each study, we provide both a clear, plain-language explanation and a detailed technical summary, ensuring that whether you are a curious student or a seasoned researcher, you can grasp the latest findings without getting lost in jargon.

The papers listed below represent the newest physiological research recently shared on bioRxiv, ready for you to explore.

Sex- and hepatocyte PPARγ-dependent effects of an obesogenic dietary approach to induce MASH with fibrosis in mice

This study demonstrates that a specific high-fat, high-cholesterol, and fructose-supplemented diet successfully induces obesity and MASLD in both male and female mice, but progression to MASH with fibrosis occurs exclusively in males through a hepatocyte PPARγ-dependent mechanism involving the downregulation of methionine metabolism.

Multi-omic profiling of early pregnancy small and large plasma extracellular vesicles reveals placental, metabolic, and structural adaptation signatures

This study utilizes multi-omic profiling to demonstrate that small and large plasma extracellular vesicles in early pregnancy possess distinct yet complementary molecular signatures reflecting placental, metabolic, and structural adaptations, thereby establishing a foundational framework for linking these vesicle subtypes to pregnancy outcomes.

TUDCA treatment restores aortic and perivascular adipose tissue function in post-weaning protein-restricted mice

This study demonstrates that TUDCA treatment restores vascular and perivascular adipose tissue function in male mice subjected to post-weaning protein restriction by attenuating endoplasmic reticulum stress, fibrosis, and associated molecular dysregulation.

Chronically elevated FGF23 drives sustained renal ERK signaling and inflammatory transcriptional programs mitigated by cFGF23 gene therapy

This study demonstrates that chronically elevated FGF23 levels drive sustained renal ERK signaling and inflammatory responses in chronic kidney disease, which can be effectively mitigated by C-terminal FGF23 (cFGF23) gene therapy.

Multimodality Molecular Profiling Nominates Targetable Mechanisms in Progressive RV Dysfunction

This study utilizes multi-omics profiling of a pig model to characterize the cellular and molecular landscape of progressive right ventricular dysfunction, identifying specific mechanisms such as impaired mitochondrial proteostasis, defective macrophage efferocytosis, and activated ribotoxic stress responses as potential therapeutic targets.

Differential Regulation of Hepatic Macrophage Fate by Chi3l1 in MASLD

This study identifies chitinase 3-like 1 (Chi3l1) as a critical metabolic regulator that selectively protects embryo-derived Kupffer cells from stress-induced death by inhibiting glucose uptake, thereby preventing their replacement by inflammatory monocyte-derived macrophages and mitigating the progression of metabolic dysfunction-associated steatotic liver disease (MASLD).

A loss-of-function variant in GFRAL associates with increased alcohol consumption in humans

This study identifies a loss-of-function variant in the GFRAL receptor that is associated with increased alcohol consumption in humans and demonstrates that GDF15 acts as an endocrine signal induced by alcohol exposure to suppress intake, suggesting a natural mechanism for limiting alcohol consumption.
