Polymorphisms in gene promoters and their transactivation activities. / CUHK electronic theses & dissertations collection

January 2008 (has links)
Briefly, some findings in my research are as follows: (1) The genetic variants of the CA repeats in IGF1 promoter 1 can affect the activity of promoter 1, and the CA repeat showed a suppressive effect on the activity of the promoter 1 of IGF1 gene. EMSA results have shown that the CA repeats could bind to certain nuclear protein. (2) The SNPs T/C (rs5742612) and T/A (rs2288377) can also affect the activity of the promoter 1 in IGF1 gene, and the activity of C-A haplotype is significantly higher than that of T-T haplotype. EMSA results have shown that the SNP T/A (rs2288377) could bind to certain nuclear protein. (3) I developed the new dual reporter assay method to investigate the transactivation interaction between the SNP T/G (rs2071430) and C/A (rs17000900) in the MxA promorer. This new method can not only improve the detection limit for small difference between haplotypes, but also calculate the model of transactivation effect between these two SNPs. The results were better than those of traditional method, and it gave a clear-cut demonstration of the effect of interaction between these two SNPs on the activity of MxA promoter. / In addition, in the IGF1 study, the core promoter region of promoter 2 was identified through 5' deletion mutagenesis methods. Moreover, a cell-type specific mechanism of bidirectional activation of promoter was found. / Recently, more and more studies focus on gene function with the completion of the Human Genome Project. It is well known that polymorphism of human genome sequence is a common phenomenon in the human population. Specially, a lot of genetic polymorphisms, including single nucleotide polymorphisms (SNPs) and microsatellites, have been reported in the regulatory region of many genes. However, the effects of most of these genetic polymorphisms on gene expression are still unknown. The polymorphisms in the promoter can play an important role in the gene regulation. For example, some SNPs located in the transcription factor binding site (TFBS) can affect gene transcription. So, it is very necessary to directly study the effect of genetic variants on promoter transactivation activities. In this study, we studied the effect of genetic polymorphisms on gene expression through reporter gene assay, electrophoretic mobility shift assay (EMSA), and so on. And the candidate genes include insulin-like growth factor 1 (IGF1) and myxovirus resistence 1 (MxA). Some SNPs and microsatellites have been reported in the promoters of these genes. In our previous researches, we focused on the study of the association between these polymorphisms and some diseases, and it was found that a few SNPs significantly associated with relevant diseases. Based on the previous results, in my project, I developed new functional assays and also improved existing methods to analyse the functional effect of these genetic variants of promoters on transactivation activities. / by Huang, Wei. / "March 2008." / Adviser: Nelson Leung Sang Tang. / Source: Dissertation Abstracts International, Volume: 70-03, Section: B, page: 1483. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2008. / Includes bibliographical references (p. 139-145). / Electronic reproduction.
