Changes in the gut microbiome during fasting‐induced molting and its effects on gut–liver function

open access: yesiMetaOmics, EarlyView.
During fasting, harmful microbiota and metabolites rise, triggering intestinal injury and activation of the TGF‐β signaling pathway, which enhances intestinal stem cell proliferation. Concurrently, hepatic function declines, indicated by increased hepatic and serum bile acids and upregulation of the non‐classical bile acid synthesis pathway.

A spatiotemporal single‐cell atlas of porcine development reveals regulatory dynamics and cellular targets of domestication

open access: yesiMeta, EarlyView.
This study presents a cross‐tissue, single‐cell/single‐nucleus transcriptomic atlas spanning from prenatal to postnatal developmental stages in pig, characterizing 83 distinct cell types from 252,033 cells. Through the construction of cross‐tissue transcriptional regulatory networks and pseudotime trajectories, we revealed that organogenesis is driven ...
