Nutrient Transporter targeted Delivery of HIV Protease Inhibitors
… novel Saq vitamin prodrugs targeting influx nutrient transporters and circumvent the P-gp mediated efflux as well as CYP3A4 mediated metabolism thus improving the absorption and bioavailability of Saq. First, two vitamin transport systems including sodium-dependent multivitamin transporter …

Distribution and Relative Abundance of Nutrient Transporter mRNA in the Gastrointestinal Tract of Black Bears
… are absorbed by the body through the action of transporter proteins expressed on the brushborder membrane of small intestinal epithelial cells. The goal of this study was to increase the understanding of the physiological processes associated with nutrient assimilation by black bears. …

Dietary and Developmental Regulation of Nutrient Transporter Gene Expression in the Small Intestine of Two Lines of Broilers
… it is important to understand how expression of nutrient transporter genes changes in response to various factors. A series of feeding trials were conducted to evaluate the dietary and developmental regulation of nutrient transporter mRNA abundance in the small intestine of two lines of broilers …

Developmental Regulation of the Expression of Nutrient Transporter and BrushBorder Membrane Hydrolase Genes in the Small Intestine of Piglets
… developmental regulation of the expression of nutrient transporter and brushborder hydrolase genes in the small intestine of piglets. Seventy piglets from seven sows were killed at birth (d 0), during suckling (d 1, 3, 7, 14, 21) and postweaning (d 22, 24, 28, 35), and intestinal segments …

Effects of Incubation Temperature and Transportation Stress on Yolk Utilization, Small Intestine Development, and Post-Hatch Performance of High-Yield Broiler Chicks
… temperature (IT) on post-hatch relative nutrient transporter gene expression, integrity of the intestinal epithelium, organ development, and performance in Ross 308 broiler chickens. Nine hundred fertile eggs were incubated at different egg-shell temperatures during development. Body …

The Spatiotemporal Dynamics of Nutrient Exchange at the Arbuscule
… arbuscular mycorrhizal (AM) fungi to meet this nutrient demand. AM symbiosis involves the fungus-to-plant transfer of phosphorus and nitrogen, and the reciprocal plant-to-fungus transfer of carbon at specialised structures within plant root cells, the arbuscules. While many studies have …

Impact of Dietary Proteins on Growth Performance, Intestinal Morphology, and mRNA Abundance in Weanling Pigs
… performance, nitrogen balance and enzyme and nutrient transporter mRNA expression in the brushborder membrane in weanling pigs. The results indicated that 6 % SDPP increased ADG and ADFI in the first 10 d after weaning (P < 0.05) without carry-over benefits in subsequent phases. There were …

Evaluation of a phytogenic feed additive on performance, nutrient digestion, and absorption in turkey poults
… in AMEn, crude protein digestibility, or nutrient transporter or pancreatic enzyme mRNA expression among treatments. However, aminopeptidase activity tended to be lower in the ileum of poults fed the PC or PFA diets compared to the NC, suggesting that the PFA may be improving protein …

Expression of Digestive Enzymes and Nutrient Transporters in the Intestine of Eimeria-challenged Chickens
… changes in expression of digestive enzymes and nutrient transporters in the intestine. The objective of this thesis was to examine the expression of digestive enzymes: APN and SI, peptide and amino acid transporters: Pept1, ASCT1, bo,+AT/rBAT, B0AT, CAT1/2, EAAT3, LAT1 and y+LAT1/2, sugar …

Short-Chain Fatty Acids and Functional Adaptations in the Neonatal Intestine
… SCFA and Bu would enhance glucose transport and transporter gene expression in a neonatal pig model of massive small bowel resection. Two-day-old neonatal pigs underwent 80% jejunoileal massive small bowel resection, and were fed via total parenteral nutrition (TPN). Piglets were randomized to …

Regulatory Balance Between the Peptide Trasporter, Pept1, and Amino Acid Transporter Gene Expression in the Enterocyte
… acids are assimilated by membrane-associated transporters into and out of enterocytes either in their free form or in the form of peptides. The peptide transporter, PepT1, is thought to be the major facilitator of peptide transport in the enterocyte. It is unknown if the peptide transporters …

Physiological and Biochemical Aspects of Methionine Isomers and Precursors in Broilers
… phase protein, leukocyte count), intestinal nutrient transporter gene expression, Met converting enzyme gene expression and activity, oxidative stress markers, and a potential pathway related to amino acid signaling. To achieve this goal, male Cobb-500 broilers were raised from day of hatch …

Developmental Gene Expression in the Small Intestine of Chickens from Lines Divergently Selected for High or Low Juvenile Body Weight
Nutrient transporters in the small intestine are responsible for dietary nutrient assimilation and therefore the expression of these transporters can influence the overall nutrient status as well as the growth and development of the animal. This thesis examined correlated responses to selection in …

The impact of mouse placental endocrine function on fetal resource allocation and adult offspring health
… and fetal outcomes are determined by adequate nutrient partitioning between the mother and fetus. In turn, the placenta plays a critical role in nutrient partitioning during pregnancy, as it is responsible for secreting hormones that induce maternal insulin resistance and transports the …
