Eukaryotic Initiation Factor 4e (Eif4e) In Complex With Eif4e Binding Protein 1 (4e-Bp1) Binds With Higher Affinity To M7gpppn Cap Of A Subset Of Human Mrnas, Izza F. Nawaz Apr 2022

Eukaryotic Initiation Factor 4e (Eif4e) In Complex With Eif4e Binding Protein 1 (4e-Bp1) Binds With Higher Affinity To M7gpppn Cap Of A Subset Of Human Mrnas, Izza F. Nawaz

Theses and Dissertations

Fluorescence anisotropy binding assays were used to analyze the binding of eIF4E in complex with 4E-BP1 onto the 5’ m7G cap of a subset of mRNA that are known to carry cap-independent translation. These studies suggest that 4E-BP1 increases eIF4E binding affinity to 5’cap of both FGF-9 and HIF-1𝝰.


Mucinomics: A Bioinformatic Analysis Of Snail Mucins, And Their Function, Maxwell B. Mcdermott Aug 2021

Mucinomics: A Bioinformatic Analysis Of Snail Mucins, And Their Function, Maxwell B. Mcdermott

Theses and Dissertations

This thesis outlines the current research on secreted snail mucus, highlighting the potential of this biopolymer, and also demonstrates a research strategy to fulfill the unmet need of examining the hierarchical structures that lead to the enormous biological and chemical diversity of snail mucus genes.


Uncovering Potential Biofilm Modulators, Liliana Margent May 2021

Uncovering Potential Biofilm Modulators, Liliana Margent

Theses and Dissertations

Biofilms have negative and positive impacts depending on the context they develop. In this work, I optimized a biofilm assay to evaluate the effect of three different types of compounds indole derivatives, 2,5 Diketopiperazines, and 12-hydroxystearic acid on the biofilm formation of E. coli.


Design Of Fibril Forming Collagen Mimetic Peptides: Heterotrimers And Nucleation Domains, Sally Tan Jan 2021

Design Of Fibril Forming Collagen Mimetic Peptides: Heterotrimers And Nucleation Domains, Sally Tan

Theses and Dissertations

This paper attempts to design collagen mimetic peptides where the triple-helical region mimics that of human Type I Collagen. With consideration for chain selection and chain register, we utilize the NC2 domain of heterotrimeric Type IX Collagen as a nucleation domain for triple-helix folding.


Analysis Of Olfactory Mrna Cap Modifications Using Rnaseh And Lc-Ms, Ilinca M. Giosan Aug 2020

Analysis Of Olfactory Mrna Cap Modifications Using Rnaseh And Lc-Ms, Ilinca M. Giosan

Theses and Dissertations

In the olfactory system, olfactory sensory neurons (OSNs) express odorant receptors (ORs) in a singular fashion through unknown mechanisms. Published data supports the notion that singularity is achieved, in part, through a modification the mRNA strand, perhaps in its 5’cap region. This theoretical study aims to test this 5’cap hypothesis.


Snow-Albedo Feedback In Northern Alaska: How Vegetation Influences Snowmelt, Lucas C. Reckhaus Aug 2020

Snow-Albedo Feedback In Northern Alaska: How Vegetation Influences Snowmelt, Lucas C. Reckhaus

Theses and Dissertations

This paper investigates how the snow-albedo feedback mechanism of the arctic is changing in response to rising climate temperatures. Specifically, the interplay of vegetation and snowmelt, and how these two variables can be correlated. This has the potential to refine climate modelling of the spring transition season. Research was conducted at the ecoregion scale in northern Alaska from 2000 to 2020. Each ecoregion is defined by distinct topographic and ecological conditions, allowing for meaningful contrast between the patterns of spring albedo transition across surface conditions and vegetation types. The five most northerly ecoregions of Alaska are chosen as they encompass …
