Phosphorylation Deficient Inducible Camp Early Repressor (Icer) Modulates Tumorigenesis And Survival In A Transgenic Zebrafish (Danio Rerio) Model Of Melanoma, Justin Wheelan, Melissa Rose Spigelman, Angelo Cirinelli, James Reilly, Carlos A. Molina

Department of Biology Faculty Scholarship and Creative Works

Melanoma, the most lethal form of skin cancer, is commonly associated with mutations in the BRAF gene, particularly BRAF^V600E, which drives tumor proliferation via the ERK1/2 signaling cascade. While BRAF inhibitors initially demonstrate efficacy, therapeutic resistance remains a significant challenge. Emerging evidence implicates the cAMP signaling pathway, particularly the cAMP response element-binding protein (CREB) and its repressor, inducible cAMP early repressor (ICER), in melanoma progression and drug resistance. ICER, a transcriptional repressor regulated via Ras/MAPK-mediated phosphorylation and ubiquitination, is degraded in melanoma, undermining its tumor-suppressive role. In a braf^V600E; p53 (loss of function) transgenic zebrafish ( …

Student Perceptions About How Supplemental Instruction And Instructor Engagement Support Academic Achievement In A College-Level Statistics Course, Tasha Y. Rhodes

Walden Dissertations and Doctoral Studies

Many college students enter postsecondary education underprepared for college-level mathematics, posing challenges for course completion and degree attainment. In response, a local community college system implemented a mainstreaming initiative that places underprepared students directly into college-level statistics courses with supplemental instruction (SI). This basic qualitative study explored students’ perceptions of the role of SI and instructor engagement in supporting their success in a college-level statistics course. The research was guided by Vygotsky’s sociocultural theory. Semistructured interviews were conducted with 10 students enrolled at a comprehensive college who had completed the course. Through thematic analysis employing open coding yielded five distinct …

Articles

Shared Augmented Reality (Shared AR) is an emerging technology that enables multiple users to interact synchronously within a collocated AR environment. Yet, there is limited research on the group interactions and dynamics in Shared AR, particularly in the context of gaming. To address this gap, we investigate Shared AR group interactions using a phone-based Shared AR mobile game called Urban Legends. Through in-situ observations, focus groups, and one-on-one interviews with 22 participants, we examine how users collaborate and communicate within the game. Our findings reveal that while verbal communication predominates, non-verbal cues are often overlooked by collocated participants, and …

Protocol For Vibratome Sectioning, Immunofluorescence, And S-Phase Labeling Of Inner Ear Organoids, Jiayi Wu, Stefan Heller, Maggie S. Matern

Biology Faculty Publications

Inner ear organoids represent a potentially inexhaustible source of otic tissues, including sensory hair cells and supporting cells, for in vitro manipulation. Here, we present a protocol for labeling S-phase entry of cells in inner ear organoids using 5-ethynyl-2′-deoxyuridine (EdU), followed by fixation and vibratome sectioning. Nuclear EdU is then detected alongside protein markers of interest via immunofluorescence. This workflow enables the visualization of cell and tissue morphologies within developing organoids and assessment of how different manipulations affect cell proliferation.

Understanding how genes influence drug responses is critical for advancing personalized cancer treatments. However, identifying these gene-drug interactions in a physiologically relevant human system remains a challenge, as it requires a model that reflects the complexity and heterogeneity among individuals. Here we show that large-scale CRISPR-based genetic screens, including knockout, interference (CRISPRi), activation (CRISPRa), and single-cell approaches, can be applied in primary human 3D gastric organoids to systematically identify genes that affect sensitivity to cisplatin. Our screens uncover genes that modulate cisplatin response. By combining CRISPR perturbations with single-cell transcriptomics, we resolve how genetic alterations interact with cisplatin at the …

From Anorthosite To Silicic Volcanics: Photometry, Composition, And Buoyancy Of Crustal Rock Types On The Moon, Emily Margaret Culley

Arts & Sciences Graduate Student Theses and Dissertations

To better constrain the formation and evolution of the lunar crust, this dissertation addresses two key aspects of lunar crustal formation: the primary feldspathic crust, formed during solidification of an ancient lunar magma ocean (LMO), and non-mare silicic volcanic constructs, which represent either secondary or tertiary crustal formation processes. Specifically, we performed photometry on Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) images to determine the single-scattering albedo (SSA) of surface features that expose these two non-mare crustal rock types. Using digital terrain models (DTMs) derived from LROC NAC images of each analysis region, we accounted for potential topographic …

Improving Particle-Phase Nitrate Measurement In Pm2.5 Filter Sampling: Evaluation Of A Denuder–Nylon Filter Modification In The Spartan Network, Wenyu Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Accurate measurement of PM_2.5 composition is of global importance. Evaporation-induced mass loss introduces potential bias in filter-based PM_2.5 measurements, with ammonium nitrate volatilization from Teflon filters being a major contributor to negative mass artifacts. Previous studies have demonstrated that using an acid gas denuder in combination with nylon filters can help recover the nitrate mass. This study evaluates design modifications to the AirPhoton sampling station setup within the globally distributed Surface Particulate Matter Network (SPARTAN) incorporating an additional acid gas denuder upstream and a nylon filter downstream of the existing Teflon filter.

Two co-located AirPhoton Sampling stations were …

Safe Real-Time Obstacle Detection And Navigation Using Cbf–Clf And Cbf–Pid Control, Nicolas M. Hernandez

McKelvey School of Engineering Graduate Student Theses & Dissertations

Traditional robotic navigation pipelines typically follow a three stage architecture: obstacle detection, path planning, and low-level control for trajectory tracking. While effective in static environments, these methods often introduce latency and lack formal guarantees of safety in dynamic or unplanned for scenarios. Our work addresses these limitations by developing a real-time controller grounded in Control Barrier Functions (CBFs) and Control Lyapunov Functions (CLFs), unified through a Quadratic Program (QP). We first investigate a hybrid CBF-PID-QP controller on a 1/10 scale car, where the CBF serves as a real-time safety filter, modifying the PID output to prevent constraint violations. While this …

Turkish Journal of Veterinary & Animal Sciences

In this study, the relationship between the Growth Differentiation Factor-9 (GDF9) gene polymorphism and birth weight, as well as weights on days 30, 60, 90, was investigated in Akkaraman lambs, one of the indigenous sheep breeds of Türkiye. For this purpose, a total of 314 lambs were genotyped by PCR-RFLP method for the single nucleotide polymorphism (SNP) c.260G>A in the GDF9 gene. While GG and GA genotypes were observed in the studied breed, the AA genotype was not observed. The results showed that Akkaraman lambs were in Hardy–Weinberg (H–W) equilibrium for the GDF9-c.260G>A polymorphism (p < 0.05). In this study, a significant association was observed between GDF9-HhaI polymorphism and 30th day weight and 60th day weight in Akkaraman lambs. When the animals were analyzed according to birth type, it was observed that this factor was associated with birth weight, as well as weights on days 30, 60, and 90. It is suggested that the c.260G>A coded SNP …
