Characterization of promoter regions of HGSNAT and GBA genes, and a contribution to the study of pathogenesis of MPS IIIC and Gaucher disease
 Richtrová, Eva ; Hřebíček, Martin (advisor) ; Macek, Milan (referee) ; Adam, Tomáš (referee)
Pathogenesis of mucopolysaccharidosis type IIIC (MPS IIIC) and Gaucher disease has not been yet fully clarified, and the causes of phenotypical variability between the patients with the same genotype in Gaucher disease remain obscure. Because the variants in the regulatory regions of genes can cause phenotypical differences mentioned above, I have studied promoter regions of HGSNAT and GBA genes mutated in these lysosomal disorders. I have shown that there is an alternative promoter of GBA (P2). Additional studies were aimed to elucidate possible physiological functions of P2, and its possible role in the pathogenesis of Gaucher disease. I have found that P2 is not tissue specific, and that its variants do not influence the variability of phenotype in Gaucher patients with the same genotype. P2 is used differentially neither during the differentiation of monocytes to macrophages nor in macrophages from controls and Gaucher patients, in whom there is a prominent storage only in cells of macrophage origin. We have thus not found any changes that would suggest a role for P2 in the pathogenesis of Gaucher disease. I have characterized the promoter region of HGSNAT and shown that the binding of Sp1 transcription factor is important for its expression. Sequence variants found in HGSNAT promoter in...
