Abstract:
The signals that facilitate transcriptional and post-transcriptional gene expression regulation are still being understood. Comparative genomics approaches based on the premise that sequence or structure conservation implies functionality have successfully distinguished true regulatory sequences and structures from prediction noise. Protein-coding regions of genes have often been overlooked as potential regulatory sequence regions. A set of 8785 coding region sequences were previously found to be conserved significantly above a baseline protein-coding conservation level. We call these sequence

Abstract:
Genome-wide studies in Saccharomyces cerevisiae have revealed that the majority of the genome is transcribed on both strands, producing both coding and non-coding RNAs (ncRNAs). Initially, these ncRNAs were regarded as spurious transcripts but some have since been shown to have important roles as transcriptional regulators. Very little is understood about how ncRNAs are initiated, terminated and processed or how this influences their function. To address these questions, the expression, stability, and subcellular localization of the ncRNAs at the endogenous GAL locus was analysed. This reveale

Widespread transcription in mammals revealed unexpected discovery of non-coding elements like long noncoding RNAs (lncRNAs) and repetitive elements.

To address this, we applied a computational pipeline that discovered 2,803 highconfidence novel lncRNAs by mapping and de novo assembling billions of RNA-Seq reads in eight tissues and a primary cell line in mouse.

An additional lineage of Treg also exits the thymus in parallel to naïve T cells and together these Treg are required for prevention of autoimmunity.

Eukaryotic genomes are pervasively transcribed and frequently generate long noncoding RNAs (lncRNAs). However, most lncRNAs remain uncharacterized. In this work, a set of positionally conserved intergenic lncRNAs in the fission yeast Schizosaccharomyces pombe genome are selected for further analysis. Deleting one of these lncRNA genes (ncRNA.1343) exhibited a clear phenotype: increased drug sensitivity. Further analyses revealed that deleting ncRNA.1343 also disrupted a previously unannotated lncRNA, termed nc-tgp1, transcribed in the opposite orientation of the predicted ncRNA.1343 gene and i

Abstract:
Notch is a critical determinant of tissue organisation in metazoan development. The activation of Notch signaling is based on ligand-receptor interaction, consequentially the activated intracellular Notch domain is chaperoned into the nuclear compartment where it acts as a transcriptional activator for Notch target genes, leading to a biological outcome that may or may not be predictable. Upon activation, downstream signals contribute to resolution of dichotomies such as proliferation/differentiation or sub-lineage differentiation outcome. Idiosyncratic outcomes are common, leading experimenta

Abstract:
Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. Previously, control of gene expression was thought to be carried out exclusively by proteins. However, it is now clear that small regulatory RNAs (sRNA) also carry out gene regulatory functions. Bacteria such as E. coli harbor a large class of sRNAs that bind to mRNAs to alter translation and/or mRNA stabili

Abstract:
In this thesis we exploit piano acoustics to automatically transcribe piano recordings into a symbolic representation: the pitch and timing of each detected note. To do so we use approaches based on non-negative matrix factorisation (NMF). To motivate the main contributions of this thesis, we provide two preparatory studies: a study of using a deterministic annealing EM algorithm in a matrix factorisation-based system, and a study of decay patterns of partials in real-word piano tones. Based on these studies, we propose two generative NMF-based models which explicitly model different piano aco

Abstract:
Cellular function and physiology are largely established through regulated gene expression. The first step in gene expression, transcription of the genomic DNA into RNA, is a process that is highly aligned at the levels of initiation, elongation and termination. In eukaryotes, protein-coding genes are exclusively transcribed by RNA polymerase II (Pol II). Upon transcription of the first 15-20 nucleotides (nt), the emerging nascent RNA 5’ end is modified with a 7-methylguanosyl cap. This is one of several RNA modifications and processing steps that take place during transcription, i.e. co-trans

Abstract:
Cell growth and proliferation are processes in the cell that must be tightly regulated. Transcription of ribosomal RNA and ribosomal biogenesis are directly linked to cell growth and proliferation, since the ribosomal RNA encodes for the majority of transcription in a cell and ribosomal biogenesis influences directly the number of proteins that are synthesized. In the work presented in this thesis, we have investigated the ribosomal RNA genes, namely the ribosomal DNA genes and the 5S rRNA genes, and their transcriptional regulation.
