Dietary Protein Influences Paracellular Calcium Transport: Two Molecular Targets, Belinda M. Kotler
Dietary Protein Influences Paracellular Calcium Transport: Two Molecular Targets, Belinda M. Kotler
Master's Theses
The effect of dietary protein on bone health remains controversial. We have shown that increasing dietary protein increases calcium absorption in both humans and rats with no change in bone resorption. We used a rat model in which dietary protein increases intestinal calcium absorption and whole body calcium retention, to explore the molecular basis for this effect. Female Sprague-Dawley rats were fed a low (5%) or high (40%) protein diet for 7 days. On day 7, duodenal mucosa was harvested and total RNA isolated. Microarray analyses using these RNA samples identified 208 genes whose expression was at least 1.5 fold …

For over five decades, different experiments have been performed to research how proteins attain their native three dimensional structures. However, the folding problem continues to be a puzzle in modern science. The design of two proteins that have maximal sequence identity but different folds and functions is one method that is being used to study the relationship between protein structure and amino acid sequence. In particular, mutant proteins of Streptococcus protein G, GA and GB, have 95% sequence identity and a 3a helix fold and β4/a fold, respectively. Molecular dynamics simulations of GA95 …
