Xiao, Zhi-Qiang, and Adhip P. N. Majumdar. Induction of transcriptional activity of AP-1 and NF-kB in the gastric mucosa during aging. Am J Physiol Gastrointest Liver Physiol 278: G855–G865, 2000.—Although aging enhances expression and tyrosine kinase activity of epidermal growth factor receptor (EGFR) in the gastric mucosa, there is no information about EGFR signaling cascades. We examined the...

Sarna, Sushil K., Asensio Gonzalez, and Robert P. Ryan. Enteric locus of action of prokinetics: ABT-229, motilin, and erythromycin. Am J Physiol Gastrointest Liver Physiol 278: G744–G752, 2000.—We investigated the in vivo and in vitro locus of actions of prokinetics: motilin, erythromycin, and ABT-229. The test substances were infused close intra-arterially in short segments of the jejunum in t...

Nemere, Ilka, Rahul Ray, and William McManus. Immunochemical studies on the putative plasmalemmal receptor for 1,25(OH)2D3. I. Chick intestine. Am J Physiol Endocrinol Metab 278: E1104–E1114, 2000.—Antisera were raised against the NH2-terminus of the putative basal lateral membrane (BLM) receptor for 1,25-dihydroxyvitamin D3 [1,25(OH)2D3; BLM-VDR]. In Western analyses of BLM proteins, antibody ...

Gaster, M., P. Poulsen, A. Handberg, H. D. Schrøder, and H. Beck-Nielsen. Direct evidence of fiber type-dependent GLUT-4 expression in human skeletal muscle. Am J Physiol Endocrinol Metab 278: E910–E916, 2000.—GLUT-4 expression in individual fibers of human skeletal muscles in younger and older adults was studied. Furthermore, the dependency of insulin-stimulated glucose uptake on fiber type di...
