1. 1. Evolution of protein and non-coding RNA genes studied with comparative genomics

   Författare :Marcela Davila Lopez; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioinformatics; evolution; non-coding RNA; gene prediction; gene order; bidirectional promoter; homologue prediction; secondary structure; RNAse P; RNase MRP;

   Sammanfattning : The identification of protein and non-coding RNA (ncRNA) genes is one important step in the analysis of a genome. This thesis focuses on the identification and analysis of proteins and ncRNAs homologues by exploiting a variety of computational methods in order to reach conclusions as to their structure, function, evolution and regulation.

3. 2. Mismatch repair deficiency in colorectal cancer : prognosis and prediction for basic treatment strategies

   Författare :Ioannis Gkekas; Jan Novotny; Karin Strigård; Richard Palmqvist; Ulf Gunnarsson; Christian Sturesson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; colorectal cancer; defective mismatch repair; prognosis and prediction; Oncology; onkologi;

   Sammanfattning : Colorectal cancer (CRC) remains a significant healthcare problem worldwide, being the third most common cancer and the fourth most frequent cause of cancer death. Environmental and dietary factors such as alcohol abuse, cigarette smoking, and genetic predisposition seem to constitute the main aetiologies. LÄS MER

4. 3. From protein sequence to structural instability and disease

   Författare :Lixiao Wang; Uwe Sauer; Sven Hovmöller; Umeå universitet; []
   Nyckelord :protein domain; remote homologue; intrinsically disorder unstructured proteins; protein function; point mutation; protein family protein stability; HMMs; CRFs; SVMs;

   Sammanfattning : A great challenge in bioinformatics is to accurately predict protein structure and function from its amino acid sequence, including annotation of protein domains, identification of protein disordered regions and detecting protein stability changes resulting from amino acid mutations. The combination of bioinformatics, genomics and proteomics becomes essential for the investigation of biological, cellular and molecular aspects of disease, and therefore can greatly contribute to the understanding of protein structures and facilitating drug discovery.

5. 4. Structural Information and Hidden Markov Models for Biological Sequence Analysis

   Författare :Jeanette Tångrot; Bo Kågström; Uwe H. Sauer; Erik Sonnhammer; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HMM; structure alignment; protein structure; secondary structure; remote homologue; annotation; domain family; protein family; protein superfamily; protein fold recognition; Bioinformatics; Bioinformatik;

   Sammanfattning : Bioinformatics is a fast-developing field, which makes use of computational methods to analyse and structure biological data. An important branch of bioinformatics is structure and function prediction of proteins, which is often based on finding relationships to already characterized proteins. LÄS MER

7. 5. The use of structural information to improve biological sequence similarity searches

   Författare :Jeanette Tångrot; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bioinformatik; Hidden Markov Model; HMM; protein structure alignment; protein structure superimposition; remote homologue; FISH-server; protein annotation; Bioinformatics; Bioinformatik;

   Sammanfattning : Bioinformatics is a fast-developing field that make use of computational methods to analyse and structure biological data. An important branch of bioinformatics is structure and function prediction of proteins. To determine the structure of a protein is a crucial part in the characterisation of the molecule. LÄS MER
