Intestinal lactic acid bacteria from Muscovy duck as potential probiotics that alter adhesion factor gene expression

Z. L. Xie, Bai, D. P., Xie, L. N., Zhang, W. N., Huang, X. H., and Huang, Y. F., Intestinal lactic acid bacteria from Muscovy duck as potential probiotics that alter adhesion factor gene expression, vol. 14, pp. 12262-12275, 2015.

The purpose of this study was to assess the suitability of lactic acid bacteria (LABs) isolated from Muscovy duck as a potential probiotic. Isolates were identified by targeted polymerase chain reaction and assessed in vitro for probiotic characteristics such as autoaggregation; surface-charge; hydrophobicity; tolerance to acidic pH, bile salts and protease; and expression of genes involved in Caco-2 cell adhesion.

Molecular characterization and tissue-specific expression of invariant chain isoform in Muscovy Duck (Cairina moschata)

S. J. Liu, Chen, F. F., Wu, C., Ni, Q. S., and Yu, W. Y., Molecular characterization and tissue-specific expression of invariant chain isoform in Muscovy Duck (Cairina moschata), vol. 13, pp. 8971-8981, 2014.

Invariant chain (Ii) isoform, through its thyroglobulin-like (Tg) domain, inhibits cysteine proteases during antigen presentation in vertebrates. In birds, the Ii of Muscovy Duck (MDIi) has 2 forms: MDIi-1 and MDIi-2 (MDIi isoform). To understand the genetic information and expression characteristics of MDIi-2, polymerase chain reaction, and bioinformatic analysis were performed for MDIi-2 from healthy adult Muscovy Duck. The full-length MDIi-2 cDNA sequence was found to be 1377-base pairs, encoding a 285-amino acid protein.

Molecular characterization and tissue-specific expression of invariant chain in the muscovy duck (Cairina moschata)

S. J. Liu, Chen, F. F., Dai, Y., Wu, C., Ni, Q. S., and Yu, W. Y., Molecular characterization and tissue-specific expression of invariant chain in the muscovy duck (Cairina moschata), vol. 10, pp. 2867-2880, 2011.

The invariant chain (Ii) plays an important role as a chaperone for MHC II maturation and facilitates antigen presentation in vertebrates. We cloned, characterized and made a homology analysis of healthy adult muscovy duck Ii (MDIi), from a poultry farm in the suburban district of Hefei city in China, by rapid amplification of cDNA ends (RACE)-PCR and by measuring expression of the MDIi gene in various tissues by real-time quantitative PCR. A full-length cDNA sequence of MDIi was obtained, 1188-bp long, encoding a 222-amino acid protein.
