1. Nuclear receptor corepressor N-CoR : role in transcriptional repression
Sammanfattning : The human body consists of a multitude of cells of varying appearance and function. With a few exceptions they are genetically identical, and the key to their divergence lies in their different specific patterns of gene expression. LÄS MER
2. Dynamic regulation of the Mig1 transcriptional repressor under glucose de/repression
Sammanfattning : The budding yeast Saccharomyces cerevisiae AMP-activated protein kinase/SNF1 is a member of a highly conserved protein family present in all eukaryotes. Snf1 regulates energy homeostasis; in yeast, it is best-known for its role in cellular adaptation to glucose limitation. LÄS MER
3. Transcriptional regulation of the Epstein-Barr virus latent membrane protein 1 gene in B cells
Sammanfattning : Epstein-Barr Virus (EBV) is a ubiquitous human B-lymphotrobic herpesvirus that latently infects over 90 percent of the world´s population. EBV infection is usually benign in healthy people. LÄS MER
4. Molecular mechanisms of transcriptional repression by the orphan receptor SHP
Sammanfattning : SHP (Small Heterodimer Partner) is an atypical orphan member of the mammalian nuclear receptor family that consists of only a putative ligand-binding domain and thus cannot bind DNA. The aim of this thesis was to investigate the molecular mechanisms of the transcriptionally inhibitory effect of SHP. LÄS MER
5. Mating type switching and transcriptional silencing in Kluyveromyces lactis
Sammanfattning : To explore the similarities and differences of regulatory circuits among budding yeasts, we characterized the role of unscheduled meiotic gene expression 6 (UME6) and a novel mating type switching pathway in Kluyveromyces lactis. We found that Ume6 was required for transcriptional silencing of the cryptic mating-type loci HMLα and HMRa. LÄS MER
