Animal Research and One Health, EarlyView.Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Animal Research and One Health, EarlyView.This study analyzed the spleen transcriptomes of different chicken breeds, identified key differentially expressed genes (EGR1, FOS, and DUSP1) that regulate resistance to Salmonella infection, and elucidated the underlying regulatory mechanisms, thereby providing new targets for disease‐resistant breeding in poultry.

AbstractThe DNA ligase enzyme family catalyzes the formation of a phosphodiester bond between juxtaposed 5′‐phosphate and 3′‐hydroxyl termini in duplex DNA. This activity can seal nicks in duplex DNA or join double‐stranded DNA fragments having either blunt or cohesive ends.

Mutation Research/DNA Repair, 1990
Recent studies on eukaryotic DNA ligases are briefly reviewed. The two distinguishable enzymes from mammalian cells, DNA ligase I and DNA ligase II, have been purified to homogeneity and characterized biochemically. Two distinct DNA ligases have also been identified in Drosophila melanogaster embryos.

BioEssays, 1997
AbstractDNA joining enzymes play an essential role in the maintenance of genomic integrity and stability. Three mammalian genes encoding DNA ligases, LIG1, LIG3 and LIG4, have been identified. Since DNA ligase II appears to be derived from DNA ligase III by a proteolytic mechanism, the three LIG genes can account for the four biochemically distinct DNA

A DNA metalloenzyme with DNA ligase activity
Nature, 1995Single-stranded DNA can fold into well-defined sequence-dependent tertiary structures that specifically bind a variety of target molecules, raising the possibility that some folded single-stranded DNAs might exhibit catalytic activities similar to those of ribozymes and protein enzymes.

DNA ligases in the repair and replication of DNA
Mutation Research/DNA Repair, 2000DNA ligases are critical enzymes of DNA metabolism. The reaction they catalyse (the joining of nicked DNA) is required in DNA replication and in DNA repair pathways that require the re-synthesis of DNA. Most organisms express DNA ligases powered by ATP, but eubacteria appear to be unique in having ligases driven by NAD(+).

AbstractDNA ligases catalyze the formation of phosphodiester bonds between juxtaposed 5' phosphate and a 3'‐hydroxyl terminus in duplex DNA. This activity can repair single‐stranded nicks in duplex DNA and join duplex DNA restriction fragments having either blunt ends or homologous cohesive ends. Two ligases are used for nucleic acid research and their

DNA ligase-AMP adducts: Identification of yeast DNA ligase polypeptides
Biochimica et Biophysica Acta (BBA) - Gene Structure and Expression, 1985Yeast DNA ligase is radioactively labelled in vitro by incubating a crude cell extract with [alpha-32P]ATP. The product of this reaction is the stable covalent ligase-AMP adduct, which can be characterized by its reactivity with either pyrophosphate or nicked DNA and visualized by gel electrophoresis and autoradiography.
