　概要を見る

Rabbits were immunized with partial peptides corresponding to dog Naf-coupled myoinositol cotransporter (SMIT) and rat water channel aquaporin 3 (AQPS). Immunoblot analysis and immunofluorescence microscopy revealed that the antibodies corresponding to SMIT and to AQP3 both detected AQP3 protein in the kidney. Neither of them, on the other hand, detected SMIT protein. Immunogen peptides of both SMIT and AQP3 contain the identical sequence "KEQI" whereas other amino acids are different from each other. Immunohistochemical preabsorption studies demonstrated that the antibodies corresponding to SMIT mainly recognized the sequence "KEQI" as an epitope. These observations demonstrate that the utmost care should be taken in using anti-peptide antibodies.

Background. Fructose is a nutrient as well as a potent agent for the formation of advanced glycation end product in diabetes. GLUT5 is a facilitated-diffusion fructose transporter expressed in the small intestine and kidney. Previous reports on the localization of GLUT5 by in situ hybridization and immunohistochemistry were controversial. Methods. The expression of GLUT5 was checked by reverse transcription-polymerase chain reaction and Southern blotting and immunoblotting analyses. Localization of GLUT5 was visualized by high-resolution immunofluorescence and immunogold electron microscopy. Results. We were able to confirm the expression of GLUT5 in the kidney. GLUT5 was predominantly present in the outer stripe of the outer medulla, where it was localized in the S3 proximal tubule cells. Double labeling with phalloidin showed that GLUT5 was localized in the brush border of the S3 proximal tubule cells. Ultrastructural examination revealed that GLUT5 was present along the plasma membrane of the apical microvilli. Conclusion. GLUT5 is present at the apical plasma membrane of S3 proximal tubule cells and may serve as the transporter of fructose.

　概要を見る

Peptide transporter-1 is a H+/peptide cotransporter responsible for the uptake of small peptides and peptide-like drugs, and is present in the absorptive epithelial cells of the villi in the small intestine (duodenum, jejunum, and ileum). It has been localized to the apical microvillous plasma membrane of the absorptive epithelial cells of the rat small intestine using the immunogold electron microscopic technique. Digital image analysis of the jejunum revealed that the transporter protein was abundant at the tip of the villus and that the amount decreased from the tip of the villus to its base. The effect of dietary administration of amino acids and starvation on the expression of PepT1 in the jejunum was examined by immunoblotting and image analysis of immunofluorescence. Starvation markedly increased the amount of peptide transporter present, whereas dietary administration of amino acids reduced it. The gradient of the transporter protein along the crypt-villus axis was maintained under either condition. These observations show that it is specific to the microvillous plasma membrane and that its expression is regulated by the nutritional condition.

　概要を見る

Aquaporins (AQPs) are membrane water channel proteins expressed in various tissues in the body. We surveyed the immunolocalization of AQP3, an isoform of the AQP family, in rat epithelial tissues. AQP3 was localized to many epithelial cells in the urinary, digestive, and respiratory tracts and in the skin. In the urinary tract, AQP3 was present at transitional epithelia. In the digestive tract, abundant AQP3 was found in the stratified epithelia in the upper part, from the oral cavity to the forestomach, and in the simple and stratified epithelia in the lower part, from the distal colon to the anal canal. In the respiratory tract, AQP3 was present in the pseudostratified ciliated epithelia from the nasal cavity to the intrapulmonary bronchi. In the skin, AQP3 was present in the epidermis. Interestingly, AQP3 was present at the basal aspects of the epithelia: in the basolateral membranes in the simple epithelia and in the multilayered epithelia at plasma membranes of the basal to intermediate cells. During development of the skin, AQP3 expression commenced late in fetal life. Because these AQP3-positive epithelia have a common feature, i.e., they are exposed to an environment of possible water loss, we propose that AQP3 could serve as a water channel to provide these epithelial cells with water from the subepithelial side to protect them against dehydration.
