Motif Selection Using Simulated Annealing Algorithm with Application to Identify Regulatory Elements
Motif Selection Using Simulated Annealing Algorithm with Application to Identify Regulatory Elements A thesis presented to the faculty of the Russ College of Engineering and Technology of Ohio University In partial fulfillment of the requirements for the degree Master of Science Liang Chen August 2018 © 2018 Liang Chen. All Rights Reserved. 2 This thesis titled Motif Selection Using Simulated Annealing Algorithm with Application to Identify Regulatory Elements by LIANG CHEN has been approved for the Department of Electrical Engineering and Computer Science and the Russ College of Engineering and Technology by Lonnie Welch Professor of Electrical Engineering and Computer Science Dennis Irwin Dean, Russ College of Engineering and Technology 3 Abstract CHEN, LIANG, M.S., August 2018, Computer Science Master Program Motif Selection Using Simulated Annealing Algorithm with Application to Identify Regulatory Elements (106 pp.) Director of Thesis: Lonnie Welch Modern research on gene regulation and disorder-related pathways utilize the tools such as microarray and RNA-Seq to analyze the changes in the expression levels of large sets of genes. In silico motif discovery was performed based on the gene expression profile data, which generated a large set of candidate motifs (usually hundreds or thousands of motifs). How to pick a set of biologically meaningful motifs from the candidate motif set is a challenging biological and computational problem. As a computational problem it can be modeled as motif selection problem (MSP). Building solutions for motif selection problem will give biologists direct help in finding transcription factors (TF) that are strongly related to specific pathways and gaining insights of the relationships between genes. -
Precision Medicine in Type 2 Diabetes and Cardiovascular Disease 31 August–1 September 2016 in Båstad · Sweden
Berzelius symposium 91 Precision Medicine in Type 2 Diabetes and Cardiovascular Disease 31 August–1 September 2016 in Båstad · Sweden Programme · General information · Lectures abstracts · Poster abstracts Generously supported by: PRECISION MEDICINE IN TYPE 2 DIABETES AND CARDIOVASCULAR DISEASE · 31 AUGUST–1 SEPTEMBER 2016 1 Berzelius symposium 91 Precision Medicine in Type 2 Diabetes and Cardiovascular Disease Purpose statement: Cardiovascular disease (CVD) and type 2 diabetes are devastating and costly diseases whose prevalence is increasing rapidly around the world, projected to exceed billions of people worldwide within the next deca- des. Although drug and lifestyle interventions are used widely to prevent and treat CVD and diabetes, neither is highly effective; for example, in high risk adults, intensive lifestyle intervention delays the onset of disease by roughly 3-years and with metformin by 18-months compared to placebo control interven- tion (Knowler et al, Lancet, 2009), with diabetes “prevention” being the excep- tion, rather than the rule. Moreover, whilst some patients respond very well to therapies, others benefit little or not at all, progressing rapidly through the pre-diabetic phase of beta-cell decline and later developing life-threatening complications such as retinopathy, nephropathy, peripheral neuropathy, and CVD. As such, there is an urgent need to develop innovative and effective prevention and treatment strategies. Human biology is complex and people differ in their genetic and molecular characteris- tics, which underlies the variable response to interventions and rates of disease progression. Thus, a huge, as yet unrealised opportunity exists to optimize the prevention and treatment of CVD and type 2 diabetes by tailoring therapies to the patient’s unique biology. -

Discovery of Flexible Gap Patterns from Sequences by En Hui Zhuang A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in Systems Design Engineering Waterloo, Ontario, Canada, 2014 ©En Hui Zhuang 2014 AUTHOR'S DECLARATION I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii Abstract Human genome contains abundant motifs bound by particular biomolecules. These motifs are involved in the complex regulatory mechanisms of gene expressions. The dominant mechanism behind the intriguing gene expression patterns is known as combinatorial regulation, achieved by multiple cooperating biomolecules binding in a nearby genomic region to provide a specific regulatory behavior. To decipher the complicated combinatorial regulation mechanism at work in the cellular processes, there is a pressing need to identify co-binding motifs for these cooperating biomolecules in genomic sequences. The great flexibility of the interaction distance between nearby cooperating biomolecules leads to the presence of flexible gaps in between component motifs of a co- binding motif. Many existing motif discovery methods cannot handle co-binding motifs with flexible gaps. Existing co-binding motif discovery methods are ineffective in dealing with the following problems: (1) co-binding motifs may not appear in a large fraction of the input sequences, (2) the lengths of component motifs are unknown and (3) the maximum range of the flexible gap can be large. -
