Aquaporins in complex tissues. II. Subcellular distribution in respiratory and glandular tissues of rat.

The molecular pathways for fluid transport in pulmonary, oral, and nasal tissues are still unresolved. Here we use immunocytochemistry and immunoelectron microscopy to define the sites of expression of four aquaporins in the respiratory tract and glandular epithelia, where they reside in distinct, nonoverlapping sites. Aquaporin-1 (AQP1) is present in apical and basolateral membranes of bronchi...

Aquaporins in complex tissues. I. Developmental patterns in respiratory and glandular tissues of rat.

Developmental expression of aquaporin water transport proteins is not well understood in respiratory tract or secretory glands; here we define aquaporin protein ontogeny in rat. Expression of aquaporin-3 (AQP3), AQP4, and AQP5 proteins occurs within 2 wk after birth, whereas AQP1 first appears before birth. In most tissues, aquaporin protein expression increases progressively, although transien...

Aquaporins in complex tissues: distribution of aquaporins 1-5 in human and rat eye.

Multiple physiological fluid movements are involved in vision. Here we define the cellular and subcellular sites of aquaporin (AQP) water transport proteins in human and rat eyes by immunoblotting, high-resolution immunocytochemistry, and immunoelectron microscopy. AQP3 is abundant in bulbar conjunctival epithelium and glands but is only weakly present in corneal epithelium. In contrast, AQP5 i...

The subcellular distribution of substance P in the nervous tissues.

HEBB and WHITTAKER (1958) have described the isolation of a subcellular fraction of brain tissue which contains the bound acetylcholine (ACh) and choline acetylase. This fraction was further studied by WHITTAKER (1959), his results providing an evidence for physiological significance of his "synaptic vesicle fraction". On the other hand, it has been reported hitherto, that substance P (SP) is p...

Subcellular localization and distribution of the reduced folate carrier in normal rat tissues

The reduced folate carrier (Rfc1; Slc19a1) mediated transport of reduced folates and antifolate drugs such as methotrexate (MTX) play an essential role in physiological folate homeostasis and MTX cancer chemotherapy. As no systematic reports are as yet available correlating Rfc1 gene expression and protein levels in all tissues crucial for folate and antifolate uptake, storage or elimination, w...
