Abstract
Proteini GLI važni su sudionici signalnog puta Hedgehog-GLI čiji se razni poremećaji u signalizaciji povezuju se s razvojnim deformacijama te onkološkim oboljenjima. U fokusu ovog rada nalazi se protein GLI3, jedan od tri izoforme proteina GLI. Protein GLI3 u svom punom obliku (GLI3FL) ima ulogu transkripcijskog aktivatora, dok njegov C-terminalni skraćeni oblik ima ulogu represora (GLI3R). Cilj ovog istraživanja je razvitak in vitro alata za ispitivanje različitih funkcija GLI3FL i GLI3R u tumorskim stanicama. Konstruiran je vektor za ekspresiju GLI3R, a njegova validacija izvršena je na staničnim linijama s različitom proteinskom ekspresijom proteina GLI3. Uvjeti transfekcije su optimizirani na staničnoj liniji fibroblasta prostate WPMY-1 s niskom razinom ekspresije, a efekt transfekcije ispitan je na staničnoj liniji metastatskog melanoma A375 s visokom razinom ekspresije, te uspoređen s djelovanjem spojeva koji mijenjaju omjere GLI3FL/GLI3R. Nakon transfekcije staničnih linija, analizom po Westernu dokazana je povećana ekspresija proteina GLI3R, a RT-qPCR metodom je potvrđena povećana ekspresija gena GLI3. Imunofluorescencijskom metodom proteini GLI3 su lokalizirani u citoplazmi te u jezgri stanica.
Abstract (english)
GLI proteins are essential members of the Hedgehog-GLI signaling pathway, and aberrations in which are associated with developmental deformities and oncological diseases. This thesis focuses on the GLI3 protein, one of the three isoforms of GLI proteins. The GLI3 protein in its full form (GLI3FL) has the role of a transcriptional activator, while its C-terminal shortened form has the repressor effect (GLI3R). This research aims to develop an in vitro tool for testing the different functions of GLI3FL and GLI3R in tumor cells. A GLI3R expression vector was constructed and validated on cell lines with different basal expression of the GLI3 protein. The transfection conditions were optimized on the low-expressing WPMY-1 cell line, and the transfection effect was tested on the high-expressing A375 cell line, and compared with the effect of compounds which affect the GLI3FL/GLI3R ratio. After the transfection of the cell lines, increased protein expression of GLI3R was demonstrated by the Western blot, and increased gene expression of GLI3 was confirmed by the RT-qPCR method. GLI3 proteins were localized in the cytoplasm and the cell nucleus using immunofluorescent staining.
