The Role Of Klotho In Adult Neurogenesis, Ann Laszczyk
The Role Of Klotho In Adult Neurogenesis, Ann Laszczyk
All ETDs from UAB
Klotho is an anti-aging protein that when upregulated, extends lifespan and enhances cognition. Klotho knockout mice age prematurely and die by ~8 weeks of life after developing cognitive impairment. Klotho function outside of the brain is well established but the protein’s action within the brain remains unknown. As klotho regulates peripheral stem cell populations, I sought to determine whether klotho contributes to cognition through a role in the maintenance of the adult hippocampal neurogenic niche. I examined adult mouse neurogenesis using global klotho-deficiency or global klotho overexpression models. Klotho knockout brains show reduced progenitor proliferation and granule cell production while …

Phenomic And Metabolomic Analysis Of Chronological Aging In Saccharomyces Cerevisiae, Haley Albright
All ETDs from UAB
Systematic investigation of chronological lifespan (CLS) in the Saccharomyces cerevisiae yeast gene knockout and knockdown (YKO/KD) strains reveals genes, path-ways, and interactions of potential relevance for aging of all eukaryotic cell types. Growth curves obtained by quantitative high-throughput cell array phenotyping (Q-HTCP) of the entire YKO/KD strain collection provide comprehensive snapshots of the influence of each individual gene on CLS. Yeast CLS is also influenced by media com-position, auxotrophic background, and media buffering. We used Q-HTCP to analyze CLS of the YKO/KD libraries, focusing on the interaction between gene networks and media buffering, with respect to their influence on CLS. …
