Individual biology labs handle increasingly large data sets. Ensuring accurate data entry, consistent sample metadata, and ease of access to the data once it is stored, are critical for both the integrity of analysis as well as productivity of the lab. Chapter 1 one of this thesis describes three implementations of software meant to facilitate handling data and metadata in the lab as the size of the data and complexity of analysis scale. The first piece of software is a database and entry interface for storing a large and varied amount of data on biological samples. The second is a …

Cell-to-cell variation in gene expression and metabolite levels have a significant impact on ensemble productivity of microbial bioproduction. New metabolic engineering tools and approaches are needed that consider cell cultures as an amalgam of uniquely behaving individuals to improve the slow commercialization of metabolically engineered systems. Stochastic cellular process including gene expression, metabolism, and growth lead to phenotypic variation between genetically identical cells. Understanding and the ability to control microbial phenotypic variation is key to improving microbial bioproduction metrics. During protein translation, codon usage strongly influences ensemble gene expression but the effect on the variation of gene expression was not …

Average lifespan differs greatly between species, but lifespan among same-species individuals is also highly variable. While much effort has been devoted to uncovering longevity-associated traits and lifespan-extending perturbations in humans and model organisms, how differences in lifespan arise between individuals is unknown. Studies of human identical twins demonstrate that surprisingly little of the variation in lifespan between individuals can be explained by genetics and shared environment. Furthermore, even genetically identical C. elegans reared in highly homogeneous environments display a degree of variability in lifespan similar to that of outbred human populations. Thus, longevity must be determined at least in part …
Acetylation Profiles Of Histone And Non-Histone Proteins In Breast Cancer, Alla Karpova
Acetylation Profiles Of Histone And Non-Histone Proteins In Breast Cancer, Alla Karpova
McKelvey School of Engineering Theses & Dissertations
This study evaluates the impact of protein acetylation on breast cancer gene expression and the regulation of metabolism. Acetylation is the second abundant post-translational modification after phosphorylation, regulating protein activity and function. The alterations in acetylation of both histone and non-histone proteins is known to be related to many human diseases, including cancer. Acetylation and deacetylation of histones is closely associated with the regulation of gene expression, while acetylation of non-histone proteins may have a broad effect on major cellular processes, such as proliferation, metabolism, cell cycle and apoptosis, imbalanced regulation of which is essential for cancer development. Therefore, it’s …
