101 Scamfer, SierraStudying pancreatic acinar cell differentiation through transcription factor reprogrammingPancreatic ductal adenocarcinoma is a highly lethal human cancer that originates from acinar cells in the pancreas. Ptf1a is a transcription factor that plays an important role in the development of the pancreas and in the differentiation and maintenance of acinar cells. Ptf1a expression is lost dur...2021
102 Enriquez, Trisha Pauline DiazSubstrate use within the drosophila melanogaster species subgroupEffective sensory perception is a vital aspect of survival for living organisms such as Drosophila. More specifically, olfaction, or the sense of smell, is essential because the detection of odors allows it to find potential food, danger, or specifically, where to lay eggs. This review will examine ...2021
103 Watkins, Ryan DavisSuppression of lymphangiogenesis using VEGF-C trapThe lymphatic system is responsible for controlling systemic fluid buildup. Lymphangiogenesis is a dynamic process involving sprouting, and maintaining new lymphatic vasculature. Vascular endothelial growth factor C (VEGF-C) is as a key growth factor that induces lymphangiogenesis by binding VEGF re...Lymphatics - Growth; Vascular endothelial growth factors - Antagonists; Lymphangiogenesis; VEGF-C trap2014-05
104 Rowe, Ana BrunsThe suppression of signal-switching defects in the Escherichia coli serine chemoreceptorThe model bacterium Escherichia coli contains a chemotaxis system that allows the cell to change its swimming behavior in response to its environment. As the cell swims, transmembrane chemoreceptors detect concentration changes in attractant and repellent compounds and transmit signals across the in...2023
105 Domagala, DrueSynthesis of protacs to inhibit toll-like receptorsThe immune system is the body's defense against pathogens. Since it has to be able to withstand the fast-evolving nature of microscopic invaders, the immune system has a variety of mechanisms to recognize and destroy them. One way that pathogens are recognized is through toll-like receptor (TLR) sig...2022
106 Judd, David PaulTelomere proteins of Drosophila melanogaster: HipHop and MSK81DNA molecules encoding two proteins, HipHop and MSK81, were cloned into bacteria so as to make large amounts of these proteins that bind to telomeres of Drosophila (fruit fly) chromosomes. The goal was to determine whether known DNA binding motifs are present in HipHop and MSK81. Understanding how t...Biology2012-05
107 Roestenburg, JessicaTesting the Perceptual Salience of Spectral Content in Zebra Finch SongBirds actively adjust the resonance properties of the upper vocal tract during singing, which results in specific harmonic structures of song elements. To what degree upper vocal tract filtering is relevant for the perceptual salience of song is poorly understood. This research utilizes (1) a biolog...2018
108 Woodruff, DerekUncovering Synaptic Defects resulting from loss of the intellectual disability and autism-associated gene Kirrel3Neurodevelopmental disorders severely impact an individual's life. Surprisingly, the genetic and cellular cause of over half of intellectual disability cases and more than 80% of autism spectrum disorders remain undiscovered1,2. It is likely that mutations in molecules regulating synapse development...2017
109 Amaechi, AyanaUnderstanding sex differences in early predictors of pathological aggression with a mouse modelAntisocial behavior (ASB) is characterized by aggression, violence, drug use, thrillseeking behavior, and delinquent behavior. While childhood and adolescent maltreatment contribute to the ontogeny of this condition, converging evidence suggests that genetic factors play an equally important role. T...MAOA; pathological aggression; sex differences; stress; early development; animal models2021
110 Lee, ZacharyUsing Drosophila to investigate p53 life-or-death decisionsThe p53 tumor suppressor is a central regulator of cellular responses to DNA damage. When DNA damage cannot be repaired most cells undergo p53-dependent cell death. Thisp55-mediated apoptosis is important to eliminate cells with damaged genomes and provides an important block to the development of c...Biology2013-05
111 Som, SaritaVirus-like weapons used for competition in wild plant populationsPlant diseases caused by bacterial pathogens pose significant economic challenges globally, necessitating the exploration of alternative methods for controlling bacterial infections in plants. Tailocins, virus-like weapons produced by bacteria, have emerged as potent antibacterial agents and hold po...2023
112 Checketts, CynthiaWhy white mice? improving biological literacy through animal historyThroughout the undergraduate experience, biology students are introduced to hundreds of experiments, theories, and principles, many of which are rooted in animal experimentation. However, in required and information-heavy biology courses, the erasure of animals from the scientific story-which repres...2021
