Riboflavin, inozivikanwawo sevhitamini B2, inotakurwa nepakati pebiological membrane kupinda nhengo dzakasiyana siyana nemafambisirwo ekufambisa.Riboflavin transporter RFVT3 inoratidzwa mudumbu diki uye yakakurudzirwa kuti igare muapical membranes emukati epithelial masero.Muchidzidzo ichi, takaongorora kushanda kweRFVT3 mukutora riboflavin tichishandisa intestinal epithelial T84 masero uye mbeva ura hudiki.T84 masero anoratidza RFVT3 uye akachengetedza unidirectional riboflavin kutakura inoenderana nekunyura kwemukati.Apical [(3)H] riboflavin uptake yaive pH-inotsamira muT84 masero.Kutora uku hakuna kukanganiswa neNa(+) kupera paapical pH 6.0, kunyangwe yakadzikira zvakanyanya paapical pH 7.4.Iyo [(3)H] riboflavin inotorwa kubva kune apical side yeT84 masero yakanyatsovharidzirwa neRFVT3 selective inhibitor methylene blue uye yakadzikira zvakanyanya nekutapurirana kweRFVT3-diki-inopindira RNA.Muchikamu chedumbu, RFVT3 yakaratidzwa mujejunum uye ileum.Mouse jejunal uye ileal permeabilities ye [(3)H] riboflavin yakayerwa nenzira ye in situ yakavharwa-loop uye yakaderedzwa zvakanyanya nemethylene blue.Mhedzisiro iyi inosimbisa kuti RFVT3 yaizoshanda mukunyudzwa kweriboflavin muapical membranes emukati epithelial masero.
