Abstract

Cilj ovog rada bio je uspostavljanje odgovarajućeg in vitro model sistema za proučavanje transkripcione regulacije ekspresije humanog SOX18 gena. U ovom radu prikazana je ekspresiona analiza SOX18 gena u permanentnim ćelijskim linijama kao i prva karakterizacija uzvodnog regulatornog regiona ovog gena. Primenom RT-PCR, Northern i Western blot eseja, ustanovljeno je da je SOX18 geneks­primiranu HeLa ćelijskoj liniji i da ove ćelije predstavljaju adekvatan model sistem za proučavanje transkripcione regulacije ekspresije ovog gena. Takođe, u ovom radu je prikazano i kloniranje i prva karakterizacija uzvodnog regulatornog regiona SOX18 gena. Pokazano je da region 892 bp uzvodno od ATG kodona sadrži regulatorne elemente neophodne za transkripciju i da ovaj region sadrži promotor SOX18 gena.<br />The aim of this study was to establish an adequate in vitro model system for studying transcriptional regulation of the human SOX18 gene. The paper presents an analysis of expression of this gene in cultured cell lines and characterization of its 5' flanking region. Using RT-PCR, Northern and Western blot analysis, we demonstrated SOX18 expression in HeLa cells, indicating that this cell line provides a suitable model system for studying transcriptional regulation of the given gene. We also cloned, sequenced and for the first time characterized the human SOX18 5’ flanking region. It is shown that the region 892 bp in size immediately upstream from the start codone harbors regulatory elements sufficient for transcription and represents an SOX18 promoter region.
