Journal ArticleDOI
Proline and hydroxyproline metabolism: implications for animal and human nutrition
Guoyao Wu,Guoyao Wu,Fuller W. Bazer,Robert C. Burghardt,Gregory A. Johnson,Sung Woo Kim,Darrell A. Knabe,Peng Li,Xilong Li,Jason R. McKnight,M. Carey Satterfield,Thomas E. Spencer +11 more
TL;DR: Work with young pigs (a widely used animal model for studying infant nutrition) has shown that supplementing 0.1% proline to a proline-free chemically defined diet dependently improved daily growth rate and feed efficiency while reducing concentrations of urea in plasma.
Journal ArticleDOI
Impacts of arginine nutrition on embryonic and fetal development in mammals.

TL;DR: Arginine plays an important role in conceptus (embryo and extra-embryonic membranes) development in pigs and sheep as mentioned in this paper, and it has been shown that dietary supplementation with 0.83 % L-arginine to gilts consuming 2 kg of a typical gestation diet between either days 14 and 28 or between days 30 and 114 of pregnancy increases the number of live-born piglets and litter birth weight.
Journal ArticleDOI
Protein delivery into live cells by incubation with an endosomolytic agent
Alfredo Erazo-Oliveras,Kristina Najjar,Laila Dayani,Ting-Yi Wang,Gregory A. Johnson,Jean-Philippe Pellois +5 more
TL;DR: It is reported that a tetramethylrhodamine-labeled dimer of the cell-penetrating peptide TAT, dfTAT, penetrates live cells by escaping from endosomes with high efficiency and mediating endosomal leakage.
Journal ArticleDOI
Pig blastocyst-uterine interactions.
TL;DR: Details of gestation in the pig with respect to uterine biology, implantation, placentation, fetal development and parturition are provided.
Journal ArticleDOI
Amino acids and gaseous signaling
Xilong Li,Fuller W. Bazer,Haijun Gao,Wenjuan S. Jobgen,Gregory A. Johnson,Peng Li,Jason R. McKnight,M. Carey Satterfield,Thomas E. Spencer,Guoyao Wu +9 more
TL;DR: Recent advances on gaseous signaling have greatly expanded basic knowledge of amino acid biochemistry and nutrition, which will aid in the design of new nutritional and pharmacological means to prevent and treat major health problems related to developmental biology and nutrient metabolism.
