Riboflavin, tseem hu ua vitamin B2, yog thauj mus los ntawm cov kab mob lom mus rau ntau yam kabmob los ntawm kev thauj mus los.Riboflavin transporter RFVT3 yog qhia nyob rau hauv cov hnyuv me thiab tau hais kom nyob rau hauv lub apical daim nyias nyias ntawm cov hnyuv epithelial hlwb.Hauv txoj kev tshawb no, peb tau tshawb xyuas qhov kev koom tes ua haujlwm ntawm RFVT3 hauv riboflavin absorption siv txoj hnyuv epithelial T84 hlwb thiab nas me me.T84 hlwb qhia RFVT3 thiab txuag unidirectional riboflavin thauj mus rau txoj hnyuv nqus.Apical [(3)H] riboflavin uptake yog pH-nyob rau hauv T84 hlwb.Qhov kev txhawb nqa no tsis cuam tshuam los ntawm Na(+) depletion ntawm apical pH 6.0, txawm hais tias nws tau txo qis ntawm apical pH 7.4.Lub [(3)H] riboflavin uptake los ntawm sab apical ntawm T84 hlwb tau prominently inhibited los ntawm RFVT3 selective inhibitor methylene xiav thiab txo qis los ntawm transfection ntawm RFVT3-me-interfering RNA.Hauv plab hnyuv, RFVT3 tau qhia hauv jejunum thiab ileum.Mouse jejunal thiab ileal permeabilities ntawm [(3)H] riboflavin tau ntsuas los ntawm txoj hauv kev kaw-voj thiab tau txo qis los ntawm methylene xiav.Cov txiaj ntsig no tau pom zoo tias RFVT3 yuav ua haujlwm tau zoo hauv kev nqus riboflavin hauv cov kab mob apical ntawm txoj hnyuv epithelial hlwb.
