This has made tECM a promising biomaterial in the fields of tissue engineering and regenerative medicine in recent years.

Gut microbiota-host post-translational modification axis in immunometabolic diseases.

Communication between the gut microbiota and host post-translational modifications (PTMs) has been extensively characterized, and recent evidence delineates a functionally integrated gut microbiota-host PTM axis. This axis is not only essential for maintaining metabolism homeostasis but also plays diverse roles in regulating disease pathogenesis. In this review we discuss the emerging effects of microbial modulation of host PTMs by regulating substrate provisioning and enzyme activity.

Hyodeoxycholic acid modulates gut microbiota and bile acid metabolism to enhance intestinal barrier function in piglets.

Oral bile acids, particularly hyodeoxycholic acid (HDCA), serve as critical drivers for gut microbial community maturation in mice. In the first study, Cy5-labeled HDCA combined with fluorescence imaging revealed rapid gastrointestinal transit of HDCA in piglets, contrasting with its delayed absorption observed in mice. In the second study, the effects of the oral HDCA supplementation on microbiota-host metabolic interactions were investigated using four piglet model groups: OPM-HDCA (naturally born, raised germ-free (GF), and orally administered HDCA), OPM-CON (naturally born, raised GF, and orally administered PBS), SPF-HDCA (naturally born, raised GF, and received fecal microbiota transplantation (FMT) and HDCA), and SPF-CON (naturally born, raised GF with FMT but no HDCA).

Gut microbiota orchestrates skeletal muscle development and metabolism in germ-free and SPF pigs.

The gut microbiota, as a crucial symbiotic microbial community in the host, participates in regulating the host's metabolism, immunity, and tissue development. Skeletal muscle is a key tissue for movement and energy metabolism in the body, with its development and function regulated by multiple factors; however, the molecular mechanisms by which the gut microbiota influences skeletal muscle remain unclear. This study utilized germ-free (GF) and specific pathogen-free (SPF) pig models, combined with multiple analytical approaches, to systematically investigate the effects of gut microbiota absence on skeletal muscle development, muscle fiber typing, and metabolism.

Oral Plant-Derived Nanomedicines Mitigate Acetaminophen-Induced Liver Injury by Modulating the Gut-Liver Axis and Intestinal Microbiota Metabolism.

Excessive use of acetaminophen (APAP) can lead to drug-induced liver injury, with its severity influenced by gut microbiota and their metabolites. The gut-liver axis, a complex bidirectional communication system between the gut and liver, plays a crucial role in maintaining overall health. Here, an innovative oral drug delivery system is developed based on DSPE-PEG2000-modified mulberry leaf-derived exosome-like nanoparticles loaded with silymarin nanocrystals (PEG@SN-MNs).

Single cell transcriptome profiling of immune tissues from germ-free and specific pathogen-free piglet.

The commensal microbiota provides immunomodulatory signals during the development, differentiation and activation of immune cells, and is crucial for maintaining host immune homeostasis. However, the systematic effects of commensal microbiota on host immunity based on large animal model at the single-cell level remain to be resolved. Here, we utilized single-cell RNA sequencing (scRNA-seq) to analyze the transcriptome profiling containing 57,720 cells from three important immune tissues [Peyer's patches (PP), mesenteric lymph node (MLN), and spleen] of germ-free (GF) and specific pathogen-free (SPF) piglet.

Dynamic changes in the gut microbiota of SPF Bama piglets during breast and formula feeding.

The gut microbiota plays a crucial role in the growth performance, health status, and welfare of pigs. Breast milk is a key factor in the colonization of gut microbiota and the overall health of newborn piglets. With advancements in breeding technology, formula milk has been widely adopted as a substitute for breast milk.

Identification and Functional Analysis of Key microRNAs in the Early Extrauterine Environmental Adaptation of Piglets.

Neonatal mammals must rapidly adapt to significant physiological changes during the transition from the intrauterine to extrauterine environments. This adaptation, particularly in the metabolic and respiratory systems, is essential for survival. MicroRNAs (miRNAs) are small noncoding RNAs that regulate various physiological and pathological processes by binding to the 3' untranslated regions of mRNAs.
