Synthesis Of Resveratrol Esters And Aliphatic Acids., Stanley Mofor Jing

Electronic Theses and Dissertations

Resveratrol (RV) is a naturally occurring phytoalexin of the stilbenoid family produced by some plant species, and present in grape skin, peanuts, and red wine. It has been found to exhibit anti-cancer, anti-inflammatory, anti-viral, anti-aging, cardio protective, and anti-oxidant properties. Bioavailability is a huge setback that limits the potentials of RV. As a result, efforts have been made to design and synthesize RV esters and aliphatic acids in an attempt to increase its bioavailability, solubility in water, and possibly improving its biological activities. Resveratrol esters, 3,5,4'-triacetyloxystilbene (2) and Methyl 1,1',1''- (3,4',5-stilbenyl)-1,6-hexanedioate (3) have been synthesized. Compound 3 is a new …

Part 1: Size-Independent Quantification Of Ligand Binding Site Depth In Receptor Proteins. Part 2: Representing Rod-Shaped Protein 3d Structures In Cylindrical Coordinates, Srujana Cheguri

Theses

Abstract 1 We have developed a web server that implements the two complementary methods to quantify the depth of ligand and/or ligand binding site (LBS) in a protein-ligand complex. The two methods are the `secant plane' (SP) and the `tangent sphere' (TS) methods. In the SP and TS methods, the protein molecular centroid (global centroid, GC), and the LBS centroid (local centroid, LC) are first determined. The SP is defined as the plane passing through the LBS centroid and normal to the line passing through the LC and the protein molecular centroid. The "exterior side" of the SP is the …

Microarray-Based Cancer Prediction Using Single Genes., Xiaosheng Wang, Richard Simon

Journal Articles: Genetics, Cell Biology & Anatomy

BACKGROUND: Although numerous methods of using microarray data analysis for cancer classification have been proposed, most utilize many genes to achieve accurate classification. This can hamper interpretability of the models and ease of translation to other assay platforms. We explored the use of single genes to construct classification models. We first identified the genes with the most powerful univariate class discrimination ability and then constructed simple classification rules for class prediction using the single genes.

RESULTS: We applied our model development algorithm to eleven cancer gene expression datasets and compared classification accuracy to that for standard methods including Diagonal Linear …

Quantification Of Protein Group Coherence And Pathway Assignment Using Functional Association., Meghana Chitale, Shriphani Palakodety, Daisuke Kihara

Department of Biological Sciences Faculty Publications

Background

Genomics and proteomics experiments produce a large amount of data that are awaiting functional elucidation. An important step in analyzing such data is to identify functional units, which consist of proteins that play coherent roles to carry out the function. Importantly, functional coherence is not identical with functional similarity. For example, proteins in the same pathway may not share the same Gene Ontology (GO) terms, but they work in a coordinated fashion so that the aimed function can be performed. Thus, simply applying existing functional similarity measures might not be the best solution to identify functional units in omics …

Accurate Estimation Of Isoform And Gene Expression Levels From Next Generation Sequencing Data, Marius Nicolae

Master's Theses

Massively parallel transcriptome sequencing is quickly replacing microarrays as the technology of choice for performing gene expression profiling due to its wider dynamic range and digital quantitation capabilities. However, accurate estimation of expression levels from sequencing data remains challenging due to the short read length delivered by current sequencing technologies and still poorly understood protocol- and technology-specific biases.

To date, two main transcriptome sequencing protocols have been proposed in the literature. The most commonly used one, referred to as RNA-Seq, generates short (single or paired) sequencing tags from the ends of randomly generated cDNA fragments. An alternative protocol, referred to …

Sepsis is a serious medical condition characterized by bacterial infection and a subsequent massive systemic inflammatory response. The release of proinflammatory products and mediators from responding innate immune cells, such as mononuclear phagocytes, directly contributes to the pathogenesis of sepsis. The primary bacterial trigger of inflammation is lipopolysaccharide (LPS), which interacts with the germline-encoded macrophage receptor cluster of differentiation 14 (CD14) via its Lipid A moiety. In an effort to identify compounds that block LPS-induced inflammation we investigated a series of Lipid A analogs that lack a disaccharide core yet still possess potent antagonistic activity against LPS. We found it …
