Notch activates Wnt-4 signalling to control medio-lateral patterning of the pronephros [PDF]

, 2009
Previous studies have highlighted a role for the Notch signalling pathway during pronephrogenesis in the amphibian Xenopus laevis, and in nephron development in the mammalian metanephros, yet a mechanism for this function remains elusive.

Structure of a beta-galactosidase gene of Bacillus stearothermophilus [PDF]

Journal of Bacteriology, 1986
The nucleotide sequence of the bgaB gene, which encodes the thermostable beta-galactosidase I of Bacillus stearothermophilus, and its flanking region was determined. A 2,016-base-pair open reading frame observed was concluded to be for beta-galactosidase I (Mr 78,051) from observations that the amino acid composition of the enzyme and the sequence of ...

Multi‐omics analyses reveal the interaction between colonic microbiota and host in Min and Yorkshire pigs

Animal Research and One Health, EarlyView., 2023
In the present study, we created the weight gain models with Min and Yorkshire pigs and conducted the metagenomics and metabolomics of colon contents and transcriptomics of colon tissue. Further, we revealed the characteristics and functions of the colonic microbiota in Min and Yorkshire pigs and analyzed their interactions with the host. Overall, this
