Abstract

U miševa, prijenosnik natrija i glukoze (mSglt1/Slc5a1) apsorbira glukozu u četkastim membranama enterocita tankog crijeva i reapsorbira glukozu u četkastim membranama proksimalnih kanalića bubrega. Budući je stanična lokalizacija mSglt1 u drugim organima/tkivima neistražena, ekspresija mSglt1 određena je na razini mRNA i proteina usporedbom miševa divljeg tipa (Sglt1+/+) i Sglt1 knockout miševa (Sglt1-/-). Relativna ekspresija mRNA za mSglt1 određena qRT-PCRom najveća je u tankom crijevu; velika u sjemenskim vezikulama, bubrezima i žlijezdama slinovnicama (doušna, podčeljusna, podjezična); osrednja u prostati, jeziku, očima i maternici; i mala u gušterači, plućima i jetri. Imunofluorescencijskom analizom utvrđena je precizna stanična lokalizacija mSglt1 proteina u bubrezima, tankom crijevu, jetri, gušterači, žlijezdama slinovnicama, jeziku, prostati, bulbouretralnoj žlijezdi, sjemenskim vezikulama i maternici. U bubrezima miševa utvrđene su spolne razlike u ekspresiji mSglt1 na razini mRNA i proteina. Distribucija mSglt1 u različitim tkivima/organima miševa, kao učestalo korištenih pokusnih životinja, omogućava proučavanje njegove uloge u pato/fiziološkim, farmakološkim i toksikološkim istraživanjima.

Abstract (english)

In mice, sodium-glucose cotransporter (mSglt1/Slc5a1) absorbs and reabsorbs the glucose in the brush-border membrane of small intestinal enterocytes and renal proximal tubules, respectively. Due to unknown localization of mSglt1 in other organs/tissues, mSglt1 expression was determined comparing wild type (Sglt1+/+) and Sglt1 knockout mice (Sglt1-/-) at the mRNA and protein level. By qRT-PCR, mSglt1 mRNA expression was observed the highest in the small intestine; high in seminal vesicles, kidneys, salivary glands (parotid, submandibular, sublingual); medium in prostate, tongue, eyes and uterus; and small in pancreas, lung and liver. Immunofluorescence revealed detailed mSglt1 cell localization in the kidneys, small intestine, liver, pancreas, salivary glands, tongue, prostate, ulbourethral gland, seminal vesicles and uterus. In the kidneys, sex-dependent expression of mSglt1 was observed at mRNA and protein level. mSglt1 distribution in various mouse organs/tissues enables further studies of its role in patho/physiological, pharmacological and toxicological investigation in the most used experimental animals.
