Functional expression of carnitine/organic cation transporter OCTN1/SLC22A4 in mouse small intestine and liver.
Carnitine/organic cation transporter (OCTN1/SLC22A4) accepts various therapeutic agents as substrates in vitro and is expressed ubiquitously, although its function in most organs has not yet been examined. The purpose of the present study was to evaluate functional expression of OCTN1 in small intestine and liver, using octn1 gene knockout [octn1(-/-)] mice. After oral administration of [(3)H]e...
متن کاملFunctional characterization of ergothioneine transport by rat organic cation/carnitine transporter Octn1 (slc22a4).
It has been reported that organic cation/carnitine transporter 1 (OCTN1) is associated with rheumatoid arthritis and Crohn's disease. Additionally, we reported that OCTN1 is expressed in hematopoietic cells, and is associated with proliferation and differentiation of erythroid cells. However, physiological role of OCTN1 is still unclear. Ergothioneine, an anti-oxidant, was recently reported to ...
متن کاملFunctional genetic variation in the basal promoter of the organic cation/carnitine transporters OCTN1 (SLC22A4) and OCTN2 (SLC22A5).
The organic cation/ergothioneine transporter OCTN1 (SLC22A4) and the high-affinity carnitine transporter OCTN2 (SLC22A5), play an important role in the disposition of xenobiotics and endogenous compounds. Here, we analyzed the sequence of the proximal promoter regions of OCTN1 and OCTN2 in four ethnic groups and determined the effects of the identified genetic variants on transcriptional activi...
متن کاملReconstitution in liposomes of the functionally active human OCTN1 (SLC22A4) transporter overexpressed in Escherichia coli.
The hOCTN1 (human organic cation transporter 1) overexpressed in Escherichia coli and purified by Ni-chelating chromatography has been reconstituted in liposomes by detergent removal with a batch-wise procedure. The reconstitution was optimized with respect to the protein concentration, the detergent/phospholipid ratio and the time of incubation with Amberlite XAD-4 resin. Time-dependent [(14)C...
متن کاملExpression and localization of carnitine/organic cation transporter OCTN1 and OCTN2 in ocular epithelium.
PURPOSE The existence of an organic cation transport process in rabbit cornea and conjunctiva that mediates absorption of carnitine has previously been suggested. This study was conducted to determine the expression and localization of the carnitine/organic cation transporter (OCTN1 and OCTN2) in corneal or conjunctival epithelium. METHODS Reverse transcriptase-polymerase chain reaction (RT-P...
