BACKGROUND: Externalizing and internalizing disorders are common in youth but are often studied separately, preventing researchers from identifying shared (i.e., transdiagnostic) alterations in brain structure. Using data from the ENIGMA Consortium, we conducted a mega-analysis to identify shared and distinct cortical and subcortical brain alterations across internalizing (anxiety disorders and depression) and externalizing disorders (attention-deficit/hyperactivity disorder [ADHD] and conduct disorder [CD]) in youth.

METHODS: 3D T1-weighted MRI data from youth (aged 4-21 years) with anxiety disorders (n=1,044), depression (n=504), ADHD (n=1,317), and CD (n=1,172), along with healthy controls (n=4,743) were analyzed. We assessed group differences in regional cortical thickness, surface …

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart defect (CHD). TOF may present in isolation or in conjunction with one or more non-cardiac congenital anomalies or neurodevelopmental disorders (TOF+). Uncertainty regarding the efficacy of various genetic testing strategies, and an incomplete understanding of the genetic causes of TOF+, may lead to hesitancy in recommending genetic testing, particularly, clinical exome sequencing (cES). Here, we analyzed cES data from 131 individuals with TOF+. A definitive or probable diagnosis was made for 31 individuals, yielding a diagnostic rate of 23.6% (31/131). One individual received three diagnoses. Commercially available CHD panels …

Background/Objectives: Triple negative breast cancer (TNBC) is an aggressive, molecularly heterogeneous subtype of breast cancer, accounting for approximately 10–15% of all cases. While reproductive and metabolic factors contribute to breast cancer development, growing concerns about environmental exposures, alongside biological and socio-cultural influences, underscore the need for targeted prevention strategies across diverse populations. Despite increasing evidence linking biological, socioeconomic, and environmental factors to TNBC outcomes, the molecular mechanisms underlying these relationships remain poorly understood. Micro-RNAs (miRNAs), which regulate gene expression and play critical roles in cancer development, have emerged as potential mediators between environmental exposures and TNBC progression. The goal of …

Impact Of Urban Fine Particulate Matter Exposure On Cardiovascular Health, Shelby P. Briggs

Honors Theses

Air pollution, particularly exposure to fine particulate matter (PM2.5), poses a growing threat to cardiopulmonary health. PM2.5 consists of microscopic particles smaller than 2.5 microns in diameter and originates from industrial combustion, transportation, and urban dust. These particles are classified as xenobiotics and are capable of bypassing respiratory defenses to enter systemic circulation, where they cause oxidative stress, inflammation, and cardiovascular dysfunction. This study examines the effects of PM2.5 on cardiovascular function using a murine model. Male C57BL/6 mice were divided into control (saline), subchronic (10 µg), and chronic (100 µg) groups and were exposed weekly for 11 weeks via …

Purpose: Hippocampal avoidance (HA) during therapeutic whole-brain radiotherapy reduces the risk of neurocognitive function (NCF) toxicity in patients with brain metastasis. This trial hypothesized that HA during prophylactic cranial irradiation (PCI) in patients with small cell lung cancer (SCLC) leads to noninferior intracranial relapse (ICR) and reduction in NCF toxicity.

Methods: This randomized phase II/III trial enrolled patients with SCLC, no brain metastases, and response to chemotherapy. The primary end points were 12-month ICR (noninferiority design, randomized phase II) and 6-month Hopkins Verbal Learning Test-Revised (HVLT-R) Delayed Recall (DR) failure (phase III). Secondary end points were failure in any NCF …

PI3K inhibition causes apoptosis selectively in NOTCH1-mutant head and neck squamous cell carcinoma (HNSCC), but modest single-agent responses and acquired resistance (AR) limit the clinical efficacy of targeted agents. To address these limitations, we investigated novel combination therapies. We tested the efficacy of 5768 compounds as single agents and 139 in combination with PI3K inhibitors in sensitive and AR NOTCH1-mutant HNSCC cell lines. We generated synergy/efficacy classifications for the combinations using multiple metrics of statistical drug synergy and growth rate indices. The PLK1/PI3K combination's efficacy was validated using orthogonal in vitro methods and in two HNSCC xenograft models. Compound efficacy …

School of Medicine Faculty Publications

Background: Older adults use nutritional complementary and alternative medicine (CAM) to reduce the risk of (or treat) non-communicable conditions and diet deficiencies. While prior research has explored the individual use of dietary supplements, vitamins, and minerals among older adults, few studies have examined factors influencing the combined use of these modalities, especially among Southern, older adults in the United States. Methods: Data were extracted from 419 participants from the University of Alabama at Birmingham Study of Aging II, a population-based longitudinal study of mobility among community-dwelling older adults. Self-reported data, including insurance and rural residence status, was collected. Comorbidity burden …

The blood-brain barrier (BBB), formed by specialized endothelial cells (ECs), regulates the extracellular composition of the central nervous system (CNS). Little is known about whether there are regional specializations of the BBB that may control the function of specific neural circuits. We use single cell RNA-seq to characterize ECs from nine CNS regions in male mice: cortex, hippocampus, cerebellum, spinal cord, striatum, thalamus, hypothalamus, midbrain, and medulla/pons. Although there is a core BBB transcriptional profile, there are significant regional specializations. Stra6, a retinoid transporter, is highly enriched in the BBB of the nucleus accumbens shell (ShNAc) and ventral cochlear nucleus, …

MHC class I polypeptide-related sequence B (MICB) is a ligand for NKG2D. We have shown NK cells are central to lung transplant acute lung injury (ALI) via NKG2D activation, and increased MICB in bronchoalveolar lavage predicts ALI severity. Separately, we found a MICB polymorphism (MICBG406A) is associated with decreased ALI risk. We hypothesized this polymorphism would protect against severe SARS-CoV-2 respiratory disease. We analyzed 1,036 patients hospitalized with SARS-CoV-2 infection from IMPACC. Associations between MICBG406A and outcomes were determined by linear regression or Cox proportional hazards models. We also measured immune profiles of peripheral blood and the upper and lower …

Faculty, Staff and Students Publications

This study investigates a dual-acting drug delivery system using naringenin (NAR) as a folate receptor ligand to enhance intestinal uptake and encapsulated NAR for combating inflammation. The dual-acting systems were tested in vitro on cisplatin-induced human kidney-2 cells and in vivo in a mouse model of cisplatin-induced acute kidney injury (AKI). NAR-loaded passive nanoparticles [P2Ns(NAR)] and dual-acting systems [P2Ns-NAR(NAR)] showed notable advantages over unformulated NAR, reducing the required dose by up to 57 and 79%, respectively. These nanoparticles modulated immune responses, restored T cell function, and shifted macrophage polarization from proinflammatory M1 to tissue-repairing M2. In addition, P2Ns-NAR(NAR) alleviated AKI …

Clonal hematopoiesis (CH) is associated with many age-related diseases, but its interaction with Alzheimer's disease (AD) remains unclear. Here, we show that TET2-mutant CH is associated with a 47% reduced risk of late-onset AD (LOAD) in the UK Biobank, whereas other drivers of CH do not confer protection. In a mouse model of AD, transplantation of Tet2-mutant bone marrow reduced cognitive decline and β-amyloid plaque formation, effects not observed with Dnmt3a-mutant marrow. Bone-marrow-derived microglia-like cells were detected at an increased rate in Tet2-mutant marrow recipients, and TET2-mutant human induced pluripotent stem cell (iPSC)-derived microglia were more phagocytic and hyperinflammatory than …

Traditional anti-inflammatory medications-such as corticosteroids, biological agents, and non-steroidal anti-inflammatory drugs-are commonly employed to mitigate inflammation, despite their potential for debilitating side effects. There is a growing need for alternative next-generation therapies for symptomatic, unchecked, and/or detrimental inflammation with more favorable adverse effect profiles. The long history of use of gold salts as anti-inflammatory agents and the more recent exploration of gold nanoparticle (AuNP) formulations for clinical indications suggest that the targeted delivery of nanoparticles to inflammatory sites may be a promising approach worth investigating. Coupled with peptides that specifically target immune cells, AuNPs could potently counteract inflammation. Here, we …

The novel (nua) kinases 1 and 2 are two of 12 AMP-activated protein–related kinases whose signaling pathways are involved in cancer progression, as well as neurologic, fibrotic, and inflammatory diseases. Currently, there are 80 Food and Drug Administration-approved kinase inhibitors which target roughly 24 of the 500+ known human kinases, leaving most kinases underexplored, including NUAK1 and NUAK2. Thus, there is a critical need for selective inhibition of NUAK1 and NUAK2 signaling. Here, we review the protein structure, known upstream regulators and downstream targets, and expression profiles of NUAK1 and NUAK2 in cancerous compared to noncancerous tissue. We also delineate …

Children with neurodevelopmental disorders exhibit highly penetrant sleep and circadian dysfunction, but the underlying mechanisms are unclear. We asked whether a subset of individuals with neurodevelopmental disorders might have genetic variants in genes known to drive circadian rhythms. Through international collaboration, we identified ten individuals with very rare genetic variants in BMAL1, a core component of the molecular clock. These individuals exhibited overlapping signs and symptoms including developmental delay, autism spectrum disorder, and variably penetrant marfanoid features. We functionally tested the identified BMAL1 variants in cell culture and in vivo and found disrupted BMAL1 function. These findings demonstrate that …

Information Theory Optimization Of Signals From Small-Angle Scattering Measurements, Robert P Rambo, John A Tainer

Faculty, Staff and Student Publications

Small-angle X-ray scattering (SAXS) of particles in solution informs on the conformational states and assemblies of biological macromolecules (bioSAXS) outside of cryo- and solid-state conditions. In bioSAXS, the SAXS measurement under dilute conditions is resolution limited, and through an inverse Fourier transform, the measured SAXS intensities directly relate to the physical space occupied by the particles via the P(r)-distribution. Yet, this inverse transform of SAXS data has been historically cast as an ill-posed, ill-conditioned problem requiring an indirect approach. Here, we show that through the applications of matrix and information theories, the inverse transform of SAXS intensity data is a …

Leishmaniasis, a vector-borne neglected tropical disease, affects over 6.2 million people globally. Case acquisition is increasingly recognized in the United States, and in Texas, most reported cases are locally acquired and speciated to Leishmania mexicana. We conducted a scoping literature review to systematically assess contemporary research on Leishmania in humans, animals, reservoir hosts, or vectors in Texas after 2000. Out of 22 eligible studies, the most prevalent themes were case reports, followed by studies on domestic animals, reservoirs, and vectors, with several studies bridging multiple disciplines. Climate change, urbanization, and habitat encroachment appear to be driving the northward expansion …

Background: Case series report high mortality after fetal diagnosis of moderate to severe mitral regurgitation in combination with left atrial dilation, hydrops, or restrictive atrial septum. However, overall outcomes and specific high-risk features remain unclear.

Methods: We performed a multicenter retrospective cohort study of fetuses with ≥moderate mitral regurgitation and normal cardiac connections evaluated January 1, 2005 to January 31, 2016. Fetuses undergoing fetal cardiac intervention (FCI) were described separately. We assessed associations between fetal echocardiographic features and discharge mortality using mixed logistic regression and classification and regression tree modeling, stratified by studies performed < 28 and ≥28 weeks gestational age (GA).

Results: Of 67 fetuses, 96% had …
