Investigation Of Proliferation Suppressors In Genetic Fitness Screens, Walter Frank Lenoir Iv Dec 2020

Investigation Of Proliferation Suppressors In Genetic Fitness Screens, Walter Frank Lenoir Iv

Dissertations & Theses (Open Access)

Innovation of CRISPR gene-editing technology has provided scientists genome manipulation tools that allowed rapid advancement of scientific capabilities and thus improved our ability to systematically study mammalian genetic functional profiles. Genome-wide CRISPR knockout screens conducted in collections of human cell lines can knock out genes at multiple loci, and have provided new insights into functional roles for independent genes. This method has launched massive efforts in looking across genetic backgrounds for context specific genetic vulnerabilities within cancer. Much of the research effort thus far has been spent on optimizing phenotype distinctions between essential, genes required for cell fitness, and non-essential, …

Targeting Unique Domains Of Lsd1 Regulates Pediatric Glioma Innate Immunity And Nk Cell Metabolism, Cavan Bailey

Dissertations & Theses (Open Access)

Regulation of chromatin accessibility is a key mechanism of cellular identity, allowing different tissues to develop using the same DNA template. Cancers will often hijack these epigenetic pathways, reactivating developmental genes to drive growth and deactivating tumor suppressor and immune recognition genes. Chromatin-modifying proteins deposit and remove chemical moieties from histone tails to aid in governing gene expression, and these proteins have become a new therapeutic target in cancer. Traditional chemotherapeutics aim to damage DNA, dysregulate cell division, or block hormonal growth signals, but epigenetic therapy can target vulnerabilities specific to cancer cells and broadly change gene expression patterns that …


Functional Heterogeneity And Metabolic Adaptation Of Fibroblasts In Cancer, Lisa Becker Jun 2020

Functional Heterogeneity And Metabolic Adaptation Of Fibroblasts In Cancer, Lisa Becker

Dissertations & Theses (Open Access)

The tumor microenvironment is comprised of a multitude of cell types producing a milieu of cytokines, growth factors an extracellular matrix. Together, this intricate network of cells plays highly critical roles in determining a tumor’s potential to progress and metastasize. As the predominant cell types in the tumor microenvironment, cancer-associated fibroblasts (CAFs) are a key component in the regulation of tumor development and progression, but their exact functions in tumorigenesis remain poorly understood. This is partly due to the considerable heterogeneity amongst these cells, which confounds the characterization of their roles within the tumor microenvironment. Nevertheless, recent studies have provided …
