Elucidating The First Protective Mutation From Inherited Alzheimer’S Disease - Apolipoprotein E3 Christchurch (Apoe3ch) And Insights Into Apoe Ligand-Receptor Interactions, Yun Chen

Arts & Sciences Graduate Student Theses and Dissertations

Alzheimer’s disease (AD) is the major cause of dementia. An inherited form of AD (dominant inherited AD) starts much earlier in life, often in the fourth and fifth decade. A recent case report described an individual who was resistant to dominantly inherited AD caused by a PSEN1-E280A mutation and was a homozygous carrier of the APOE3 Christchurch (APOE3ch) variant. A clear separation between amyloid and tau pathology occurred in this unique AD case. However, whether APOE3ch contributed to the protective effect remains unclear. In this thesis, we generated a humanized APOE3ch knock-in mouse and crossed it to an amyloid-β (Aβ) …

Exploring The Role Of Rb1 In Cellular Differentiation Using Patient-Derived Stem Cells, Ambily Vincent

Theses and Dissertations

The Retinoblastoma (RB1) gene, predominantly recognized as a tumour suppressor, plays a crucial role in early growth and development. Mice lacking the retinoblastoma gene do not survive and exhibit defects in the differentiation of various tissues, underscoring its involvement in cellular differentiation. This suggests that the functions of the RB1 gene extend beyond its role as a tumour suppressor, encompassing cell cycle regulation, maintenance of genomic stability, cellular senescence, and cellular differentiation.

While the tumour suppressor function of the RB1 has been extensively studied, its role in cellular differentiation remains incompletely understood. Existing literature, primarily based on animal models, has …

Exploring The Roles Of Physiology And Phylogeny In Novel Signal Evolution, Mia E. Phillips

Dartmouth College Ph.D Dissertations

In animal communication, signal phenotypes are shaped by a combination of selective

forces pushing for improved transmission, efficiency, and detection, and limited by

developmental constraints in signal production and reception abilities (Morton 1975; Guilford &

Dawkins 1991; Endler 1992; Davranoglou et al. 2023). These opposing forces have resulted in

communication strategies that are broadly diverse yet similar among closely related species. We

expect to see gradual changes in signal phenotypes across different clades (Harvey & Pagel

1991). Sometimes, though, the communication strategies of closely related taxa are drastically

different (Ligon et al. 2018), indicating that selection must have overcome the …

Systemic Activation Of The Axon Degeneration Executioner Sarm1 Triggers Acute Hyperglycemia, Lillian Spatz

Arts & Sciences Graduate Student Theses and Dissertations

Communication between the nervous system and metabolic tissues directs whole body homeostasis. It is well understood that peripheral tissues respond to neural stimulation or inhibition to modulate energy usage and storage, hormone release, and stress pathways, but the neuroendocrine circuits that drive these outcomes remain ill-defined. Our lab identified sterile alpha and TIR motif containing 1 (SARM1) as the central executioner of axon degeneration in injury and disease models. We found that SARM1 is activated by an elevated NMN/NAD+ ratio and that nicotinamide analogs, including 3-AP and vacor, are converted to NMN-like intermediates that directly bind to SARM1, mimicking the …
