Visualizing Anhydrobiosis: Liquid-Liquid Phase Separation, Membraneless Organelles, And Cellular Reorganization., Clinton J. Belott
Electronic Theses and Dissertations
Water is an integral and necessary component of life. It is then, exceedingly remarkable that some species are capable of surviving virtually complete water loss for extended periods of time. Several decades of intense research into anhydrobiosis, or life without water, have given significant insights into the molecular mechanisms governing this phenomenon. Anhydrobiosis-related intrinsically disordered (ARID) proteins have been demonstrated to be critically important for desiccation tolerance in many anhydrobiotic species and exhibit a considerably wide range of protective properties that include membrane stabilization, reinforcing bioglass formation, and protein stabilization. This dissertation begins with cellular dielectrophoresis suggesting that two ARID …
Insect Developmental Plasticity: The Role In A Changing Environment, Lindsey A. Barnes
Insect Developmental Plasticity: The Role In A Changing Environment, Lindsey A. Barnes
The Cardinal Edge
Climate change has been recognized as a severe threat to biodiversity. In the rapidly growing collection of literature on the consequences of global change, researchers have recently noticed a dramatic decrease in insect populations in a wide range of habitats. Insects are extremely susceptible to climatic change, especially with regard to fluctuations in moisture and temperature. However, insects often exhibit phenotypic plasticity, where organisms will express different phenotypes when presented with a specific environmental stimulus. In developmental plasticity, environmental stimuli at the larval stage can determine adult phenotypes. This review focuses on case studies of developmental plasticity in insects, with …
A Literature Review On The Development Of Upper Limbs In Humans, Anh T. Phan
A Literature Review On The Development Of Upper Limbs In Humans, Anh T. Phan
The Cardinal Edge
The development of tetrapod upper limbs shares an evolutionary origin and has been adapted and specialized for different functions for different species, such as flight in birds, swimming and balance in sea mammals, and coordination and grabbing objects in humans. The basis of tetrapod limb development has common developmental patterns, starting with the formation of the limb bud via Sonic hedgehog (Shh) signaling, where later developmental steps are modified for specialized functions. This review covers the basic developmental patterns of mammalian tetrapod development seen in humans, beginning with the formation of the limb bud, to the axis development of the …

Dentinogenesis Imperfecta: The Genetic Causes And Outcomes, Sydney P. Johnson Ms.
The Cardinal Edge
Dentinogenesis imperfecta (DI) is a genetic disorder characterized by dentin discoloration, tooth development irregularities, and decreased tooth strength. This autosomal dominant disorder is identified in individuals of all ages. There are three classifications of dentinogenesis imperfecta, each with varying presentations and causes. This report covers normal tooth development (odontogenesis), DI development, DI classifications, and the genes involved in this genetic disorder.
Inner Ear Development And Advances In Inner Ear Organoid Formation, Paige Avery
Inner Ear Development And Advances In Inner Ear Organoid Formation, Paige Avery
The Cardinal Edge
The inner ear houses the cochlea which contains hair cells responsible for the transduction of sound waves. The process of forming these hair cells responsible for hearing is a complicated process consisting of many signaling factors that allow ectoderm to form into the otic placode, the otic vesicle, and finally prosensory cells such as hair cells (Schlosser, 2006). Loss of these hair cells contributes to deafness and hearing loss throughout life, and regeneration of these cells may serve as a therapeutic agent for those with irreversible damage. This review looks at the development of the otic placode and hair cells …

The Effects Of Alcohol On The Developing Drosophila Nervous System, Erica E. Hassoun
The Effects Of Alcohol On The Developing Drosophila Nervous System, Erica E. Hassoun
The Cardinal Edge
Ethanol is the most common human teratogen, contributing to fetal alcohol syndrome (FAS) when effects are the most severe. Key effects of fetal alcohol syndrome are observed in the nervous system. The high prevalence of prenatal alcohol exposure necessitates novel treatment and prevention methods. However, ethical issues prevent researching humans in utero. For this reason, the fruit fly Drosophila melanogaster has emerged as a model organism for studying FAS. Because Drosophila is a small and non-placental organism, its environment can be easily controlled, allowing for specific doses and time periods of ethanol exposure to be studied. This review discusses findings …

Prenylation is a type of post-translational modification in which a 15- or 20-carbon lipid is added to the carboxyl (C) terminus of the protein. Arabidopsis thaliana contains the PROTEIN PRENYLTRANSFERASE ALPHA SUBUNIT-LIKE (PPAL) gene, which encodes a protein with homology to the α-subunits of the three known prenylation enzymes, PFT, PGGT, and Rab-GGT. We previously identified two mutations in PPAL, one of which is ppal-1, which contains a T-DNA insertion in the fourth intron. We have previously observed that self-fertilizing heterozygous ppal-1 plants produce progeny in which homozygous ppal-1 is underrepresented. This project attempts to ascertain …

Investigating A Novel Function For Phosphoserine Aminotransferase 1 (Psat1) In Epidermal Growth Factor Receptor (Egfr)-Mediated Lung Tumorigenesis., Rumeysa Biyik-Sit
Electronic Theses and Dissertations
Phosphoserine aminotransferase 1 (PSAT1) catalyzes the second enzymatic step within the serine synthetic pathway (SSP) and its expression is elevated in numerous human cancers, including non-small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) mutant NSCLC is characterized by activating mutations within its tyrosine kinase domain and accounts for 17% of lung adenocarcinomas. Although elevated SSP activity has been observed in EGFR-mutant lung cancer cells, the involvement of PSAT1 in EGFR-mediated oncogenesis is still unclear. Here, we explore a putative non-canonical function for PSAT1 using biochemical approaches to elucidate unknown interacting proteins and genomic RNA-seq profiling to identify cellular …
