Bat Occurrence And Microclimatic Conditions Of The Sima Del Órgano Cave, Mexico, Luis A. Hernández, Jaime E. Gómez, Cyntia Reyes
Bat Occurrence And Microclimatic Conditions Of The Sima Del Órgano Cave, Mexico, Luis A. Hernández, Jaime E. Gómez, Cyntia Reyes
International Journal of Speleology
Caves represent an important type of shelter for many species of bats, particularly in karstic regions. In Mexico, about 60 bat species regularly use caves as roosts. The microclimate of a cave is a key component of the overall cave ecosystem. So, an adequate microclimate can minimize the energetic costs of bats associated with thermoregulation, gestation, embryonic development, parental care, lactation and social interaction. Cave environments are among the least known and most threatened on the planet, which is why we aimed to determine the monthly occurrence of bat species in the Sima del Órgano Cave, estimate the population size …

Aspen Bibliography
Aspen forests provide wildlife, watershed, and aesthetic value, and the potential for reduced fire occurrence, behavior, and severity. There is interest in planting aspen to achieve various management objectives. However, few studies have investigated the optimal conditions for aspen seedlings in the western US. We conducted two experiments to address this knowledge gap. First, we tested the effects of shading structures (i.e., logs) and biochar on the survival and growth of 960 outplanted aspen seedlings in three exclosures in a recent fire footprint. Second, we tested whether experimentally placing logs near 120 naturally-occurring post-fire aspen seedlings affected survival or growth. …

Lighting Up The Cell: Developing A Luminescent Lanthanide Probe For Detecting Rnas, Jonathan Savell
Honors Projects
An anion detecting luminescent probe, Tb:DO2A-Cs124, was repurposed for use in RNA imaging. Potential RNA aptamers were identified for the molecule using Capture-SELEX and MinION sequencing. Fluorimetry data revealed these aptamers did not allow for the probe to luminesce in the presence of target RNAs due to adenosine monophosphate’s ability to quench the emission signal.

Colonization-Persistence Trade-Offs In The Human Microbiome, Liam F. Nokes
Environmental Studies Senior Theses
Understanding how diverse microbial taxa coexist in the human body without competitively excluding one another remains a key challenge in microbiome ecology. One proposed explanation is the colonization-persistence trade-off, where species with high colonization ability are poor persisters, and vice versa. We test for this trade-off across human associated microbial communities among many individuals and in multiple body sites using a large-scale participant-level meta-analysis of longitudinal microbiome datasets curated from the MGnify database. We applied island biogeography-based models to calculate effective colonization and persistence rates for microbial families and genera across 606 individuals over twenty-six studies. Regression of the log-transformed …
The Bone Is Not Alone: Skeletal Muscle Is A Novel Source Of Fibroblast Growth Factor 23, Kylie Heitman
The Bone Is Not Alone: Skeletal Muscle Is A Novel Source Of Fibroblast Growth Factor 23, Kylie Heitman
All ETDs from UAB
Chronic kidney disease (CKD) is a major public health issue often accompanied by various pathologies. Hyperphosphatemia contributes to a range of complications, including vascular calcification, systemic inflammation, anemia, left ventricular hypertrophy, and skeletal muscle atrophy. Phosphate homeostasis is tightly regulated through a combination of renal excretion and its storage in bones, with fibroblast growth factor (FGF) 23 playing a central role in this regulation. Produced primarily by osteocytes in response to elevated serum phosphate, FGF23 helps maintain phosphate balance by promoting renal phosphate excretion and inhibiting the synthesis of vitamin D and parathyroid hormone. Dysregulation of FGF23 is associated both …

N6-methyladenosine (m6A) is an abundant internal RNA modification that can impact gene expression at both post-transcriptional and transcriptional levels. However, the landscapes and functions of m6A in human brains and neurodegenerative diseases, including Alzheimer's disease (AD), are under-explored. Here, we examined RNA m6A methylome using total RNA-seq and meRIP-seq in middle frontal cortex of post-mortem brains from individuals with or without AD, which revealed m6A alteration on both mRNAs and various noncoding RNAs. Notably, many promoter-antisense RNAs (paRNAs) displayed cell-type-specific expression and changes in AD, including one produced adjacent to MAPT that encodes the Tau protein. MAPT-paRNA is highly expressed …
Exploring Muslim American Attitudes Toward Genetic Testing: Perceptions, Barriers, And Ethical Considerations, Hannah Mahmoud
Exploring Muslim American Attitudes Toward Genetic Testing: Perceptions, Barriers, And Ethical Considerations, Hannah Mahmoud
University Honors Theses
This thesis explores perceptions and attitudes toward genetic testing within the Muslim American community, a group often underrepresented in genomic research and public health discourse. Using a community-distributed digital survey, data was collected from 50 self-identified Muslim Americans on their familiarity with genetic testing, reproductive and ethical considerations, and the influence of religious factors. While only 18% had undergone genetic testing themselves, many were familiar through family or friends, and most expressed cautious interest—especially when results could influence future family planning. Education level, age, and religious values shaped both comfort and understanding.
A key theme was the desire for culturally …

KRAS is a pivotal oncoprotein that regulates cell proliferation and survival through interactions with downstream effectors such as RAF1. Despite significant advances in understanding KRAS biology, the structural and dynamic mechanisms of KRAS allostery remain poorly understood. In this study, we employ microsecond molecular dynamics simulations, mutational scanning, and binding free energy calculations together with dynamic network modeling to dissect how engineered DARPin proteins K27, K55, K13, and K19 engage KRAS through diverse molecular mechanisms ranging from effector mimicry to conformational restriction and allosteric modulation. Mutational scanning across all four DARPin systems identifies a core set of evolutionarily constrained residues …
Distribution And Habitat Use Of Sounders Gray Whales From 1990 To 2023, Sara N. Mach
Distribution And Habitat Use Of Sounders Gray Whales From 1990 To 2023, Sara N. Mach
Honors Projects
Abstract: Every spring, a small subgroup of gray whales (Eschrichtius robustus), referred to as “Sounders,” migrate to northern Puget Sound (NPS), Washington State, to forage on small crustaceans, particularly during years of low prey availability in the Arctic, the primary foraging habitat for gray whales. In contrast to gray whales in other locations, Sounders primarily forage on ghost shrimp (Neotrypnea californiensis) while in NPS. These small crustaceans live in the sediment in the intertidal to shallow subtidal zones, so gray whales must wait for higher tides to feed. Gray whale abundance in NPS and time spent …

Around 1000 years ago, Madagascar experienced the collapse of populations of large vertebrates that ultimately resulted in many species going extinct. The factors that led to this collapse appear to have differed regionally, but in some ways, key processes were similar across the island. This review evaluates four hypotheses that have been proposed to explain the loss of large vertebrates on Madagascar: Overkill, aridification, synergy, and subsistence shift. We explore regional differences in the paths to extinction and the significance of a prolonged extinction window across the island. The data suggest that people who arrived early and depended on hunting, …

Department of Biochemistry and Molecular Biology Faculty Papers
tRNA halves are among the most abundant short non-coding RNAs in the cellular transcriptome. Here we report that in androgen receptor-positive LNCaP prostate cancer cells, the hormone-dependent 5'-tRNALysCUU half promoted cell proliferation by facilitating cell cycle progression. Global mRNA profiling upon the 5'-tRNALysCUU half depletion revealed that the mRNA of p21, a negative regulator of the cell cycle, is post-transcriptionally destabilized via a 5'-tRNALysCUU half-driven mechanism. YBX1, identified as a protein interacting with 5'-tRNALysCUU half in the cytosol, was shown to stabilize p21 mRNA. Specific sequences resembling the 5'-tRNALysCUU half, located in the 3'-UTR of p21 mRNA and termed LL588, …

A Novel Approach To Treat Trastuzumab Resistant Her2+ Breast Cancer: Activation Pkcδ, Maria Grazia Mejia Monroy
Master's Theses
In the United States, approximately one in eight women will be diagnosed with invasive breast cancer in her lifetime and one in forty will die from breast cancer. From among all the different subtypes of breast cancer, HER2+ can be found in approximately 20% of breast cancer tumors. HER2 overexpression has been associated with an aggressive form of breast cancer, increasing the risk of metastasis or recurrent tumors in 50% of patients. The standard of care for HER2 positive breast cancer, trastuzumab, has been effective for some patients; however, others develop resistance over time, leading to disease progression and metastasis. …

Metastasis is the main cause of cancer-related deaths, yet the underlying mechanisms remain elusive. Here, using clear cell renal cell carcinoma (ccRCC), a tumor type with frequent lung metastases, we conduct an in vivo genome-wide CRISPR-Cas9 screen and identify HLF as a potent suppressor of lung metastasis. HLF depletion enhances ccRCC cell migration and lung metastasis, whereas HLF overexpression abrogates these effects. In ccRCC patients, HLF expression is reduced at metastatic sites and associates with epigenetic silencing mediated by the SWI/SNF ATPase subunit BRG1. HLF levels negatively correlate with migration potential in collagen. Mechanistically, HLF regulates LPXN expression, modulating the …

The effects of cell senescence in individual cell populations of the tumor microenvironment (TME) on cancer progression remain unclear. Here, we investigated the effects of cell senescence caused by inactivation of the catalytic subunit of telomerase (Tert) in distinct TME components. We generated genetic Tert knockout (KO) mice driven by the LysM promoter in myeloid cells, by the Pdgfra or Pdgfrb promoter in mesenchymal cells, and by the Tie2e promoter in endothelial cells. We compared the effect of the Tert KOs in syngeneic models of orthotopically grafted E0771 breast adenocarcinoma, RM1 prostate adenocarcinoma, and KPC pancreatic adenocarcinoma. Tumors in LysM-Tert …

Background: The benefit of regional nodal irradiation in the treatment of breast cancer is well established for patients with pathologically positive axillary nodes, but whether it is also beneficial for patients whose nodes become pathologically tumor free (ypN0) after neoadjuvant chemotherapy remains unclear.
Methods: We evaluated whether regional nodal irradiation improves outcomes in patients with biopsy-proven, node-positive breast cancer who reach ypN0 status after neoadjuvant chemotherapy. Patients with breast cancer with a clinical stage of T1 to T3 (tumor size, ≤2 cm to >5 cm), N1, and M0 (indicating spread to one to three axillary lymph nodes but no distant …

Sample Storage Method And Collection Time Effects On Horse Hair Cortisol Concentrations, Grace Robertson, Savannah Rivers, Thomas Powell, Shea Porr
Steeplechase: An ORCA Student Journal
Serum cortisol concentration is the gold standard for evaluating stress in horses. However, it can be affected by circadian rhythms, environmental factors, and other excitatory events. Hair cortisol is less subject to these variables and is less invasive to collect, but there is a lack of published information on hair cortisol concentrations in horses. The objectives of this study were to examine 1) the impact of sample storage (Room temperature vs. Frozen) and 2) the effect of collection date (spring vs. fall), on cortisol concentration in equine hair. It was hypothesized that Frozen samples would yield higher concentrations than Room …

Changes In Morphology, Phenology, And Demography Of Several Avian Species Over 18 Years At A Restored Grassland, Ashley Mcmahon, Katie Stumpf
Georgia Journal of Science
In response to a changing climate and the loss of habitat, avian species are displaying changes in body size, migration phenology, and demography. Several species have adhered to Allen’s and Bergmann’s rules by displaying increased wing length and decreased mass, respectively, over time in response to higher temperatures. Climate change has also resulted in earlier spring migration and depending on species, either earlier or later fall migration. Finally, species affected by habitat loss often display male-skewed sex ratios and juvenile skewed age ratios. Our goal was to determine how body size, migration phenology, and demography have changed for grassland birds …
Pesticides As Multiple Stressors To Bivalves And Echinoderms, Alexandra Gabrielle Tissot
Pesticides As Multiple Stressors To Bivalves And Echinoderms, Alexandra Gabrielle Tissot
Dissertations and Theses
Pesticides are ubiquitous in aquatic environments, alongside numerous contaminants and other stressors that can result in combined exposure to target and non-target organisms. Nevertheless, traditional toxicity studies quantify the effects of these compounds at an individual level, and to a narrow range of traditional test organisms. Through this dissertation, I explored the presence and effects of commonly detected pesticides of concern in the Pacific Northwest in order to realistically quantify potential effects from combined stressors. In Chapter 2, I demonstrated my background knowledge on these select pesticides (atrazine, bifenthrin, diuron, indaziflam, and imidacloprid), including their chemical and physical properties. Using …

PARP inhibitors sensitize pancreatic ductal adenocarcinoma (PDAC) to radiation by inducing DNA damage and replication stress. These mechanisms also have the potential to enhance radiation-induced type I interferon (T1IFN) mediated anti-tumoral immune responses. We hypothesized that the PARP inhibitor olaparib would also potentiate radiation-induced T1IFN to promote anti-tumor immune responses and sensitization of otherwise resistant PDAC to immunotherapy. To test this hypothesis, we assessed the effects of olaparib and radiation on T1IFN production and sensitivity to αPD-L1 immunotherapy, as well as on the tumor microenvironment by single-cell RNA sequencing (scRNA-seq). We found that olaparib enhanced T1IFN production following radiation and …

Triple-negative breast cancer (TNBC) and inflammatory breast cancer (IBC) are the most aggressive molecular subtypes of breast cancer. Poor clinical outcomes highlight the pressing need to discover novel targets for the effective treatment of these diseases. LMP7 (β5i/PSMB8), a proteolytic subunit of the immunoproteasome, is implicated in the pathogenesis of multiple myeloma, autoimmune and inflammatory diseases, and inflammation-related cancers. However, the role of LMP7 in TNBC and IBC remains poorly characterized. Here, we evaluated the function of LMP7 in TNBC and IBC using the selective LMP7 inhibitor M3258. In human TNBC patient samples, LMP7 expression correlated strongly with CD8+ T …
