Diabetes is a growing global health concern, affecting millions and leading to severe complications if not properly managed. The primary challenge in diabetes management is maintaining blood glucose levels (BGLs) within a safe range to prevent complications such as renal failure, cardiovascular disease, and neuropathy. Traditional methods, such as finger-prick testing, often result in low patient adherence due to discomfort, invasiveness, and inconvenience. Consequently, there is an increasing need for non-invasive techniques that provide accurate BGL measurements. Photoplethysmography (PPG), a photosensitive method that detects blood volume variations, has shown promise for non-invasive glucose monitoring. Deep neural networks (DNNs) applied to …

Particulate matter containing environmentally persistent free radicals (EPFRs) is formed when organic pollutants are incompletely burned and adsorb to the surface of particles containing redox-active metals. Our prior studies showed that in mice, EPFR inhalation impaired vascular relaxation in a dose- and endothelium-dependent manner. We also observed that activation of the aryl hydrocarbon receptor (AhR) in the alveolar type-II (AT-II) cells that form the air-blood interface stimulates the release of systemic factors that promote endothelial dysfunction in vessels peripheral to the lung. AhR is a recognized regulator of microRNA (miRNA) biogenesis, and miRNA control diverse signaling pathways. We thus hypothesized …

The use of immune checkpoint inhibitors (ICI) in recent years has increasingly emerged as a second-line treatment in the management of extensive-stage small cell lung cancer (ES-SCLC) compared to conventional chemotherapy alone.
The use of combined ICI therapy by inhibiting two distinct pathways in patients with ES-SCLC has been evaluated in clinical trials. The increase incidence of immune related adverse events (Ir-AE) in these trials due to excessive immune system activation or multiple organ disorders has posed serious clinical challenges.
Here we report a dramatic and durable response to combined immune checkpoint blockade without chemotherapy and discuss the relationship between …

In-Silico Modeling And Characterization Of Kcc2 Protein Interaction With A Small Molecule Direct Agonist Identifies Potential Binding Sites For Modulating Behaviors Associated With Substances Of Abuse, William Hai Dang Ho, Alfred Amendolara, Kenyon Mitchell, Jaden Miner, Ruth Northcott, Braxton Bingham, Andrew J. Payne
Annual Research Symposium
Purpose
KCC2 is a potassium-chloride cotransporter that plays a critical role in neuronal function by regulating GABAergic signaling via chloride gradients. Maintaining this concentration gradient is crucial for balancing excitation and inhibition in the brain. While KCC2 dysregulation has been implicated in epilepsy and seizures, recent studies suggest that KCC2 inhibition results in phenotypes mirroring those seen in chronic opioid dependence. As such, increasing evidence support KCC2 being a potential therapeutic target for modulating behaviors associated with substances of abuse. Currently, only a few direct small molecule agonists against KCC2 have been reported, and no definitive active site on the …

Acute lymphocytic leukemia (ALL) is the most common leukemia in children, with the T-cell subtype (T- ALL) accounting for 15% of those cases. Despite advancements in the treatment of T-ALL, patients still face a dismal prognosis following their first relapse. Relapse can be attributed to the inability of chemotherapy agents to eradicate leukemia stem cells (LSC), which possess self-renewal capabilities and are responsible for the long-term maintenance of the disease. Mitochondria have been recognized as a therapeutic vulnerability for cancer stem cells, including LSCs. Mitocans have shown promise in T-ALL both in vitro and in vivo, with some currently in …

Class Iii Phosphatidylinositol-3 Kinase/Vacuolar Protein Sorting 34 In Cardiovascular Health And Disease, Yuanjun Shen, Jason Gleghorn
Pharmacy Faculty Scholarship
Phosphatidylinositol-3 kinases (PI3Ks) play a critical role in maintaining cardiovascular health and the development of cardiovascular diseases (CVDs). Specifically, vacuolar Protein Sorting 34 (VPS34) or PIK3C3, the only member of Class III PI3K, plays an important role in CVD progression. The main function of VPS34 is inducing the production of phosphatidylinositol 3-phosphate, which, together with other essential structural and regulatory proteins in forming VPS34 complexes, further regulates the mammalian target of rapamycin activation, autophagy, and endocytosis. VPS34 is found to have crucial functions in the cardiovascular system, including dictating the proliferation and survival of vascular smooth muscle cells and cardiomyocytes …

Investigating The Potential Of Broccoli Seed Extract To Attenuate Morphine Tolerance, Atharv Ashwin Battu, Minho Kang, Hamid Akbarali
Pharmacology and Toxicology Publications
Opioids remain one of the most effective treatment strategies for managing severe and persistent pain. However, its long-term use leads to pharmacological tolerance, requiring progressively higher doses to achieve analgesia. This dose escalation increases the risk of life-threatening side effects and dependence, underscoring the urgent need for safe adjuncts to preserve opioid efficacy. Emerging evidence suggests that morphine tolerance is linked to intestinal inflammation and disruption of gut barrier integrity. Broccoli Seed Extract (BSE), rich in the bioactive compound sulforaphane, exhibits antioxidant and anti-inflammatory properties that may protect against these effects. We hypothesized that BSE could prevent the development of …

IRBEH/Spit for Science Publications and Presentations
In the two studies that I participated in, a behavioral economic demand curve and choice procedure, we assessed whether two alpha-2 adrenergic agonists (i.e., xylazine, clonidine, and lofexidine) altered fentanyl reinforcement in male and female sprague dawley rats. We hypothesized that xylazine and clonidine would enhance fentanyl reinforcement in a proportion-dependent manner. Lofexidine interactions with fentanyl were more difficult to predict. The data showed that xylazine did not enhance fentanyl reinforcement. Furthermore, these results were consistent with those of clonidine and lofexidine. In opposition to xylazine, clonidine and lofexidine are approved for human use for antinociception, reduction of blood pressure, …

High-Throughput Drug Screening For Disease-Modifying Arthritis Therapy, Janapriya Vijayakumar
High-Throughput Drug Screening For Disease-Modifying Arthritis Therapy, Janapriya Vijayakumar
Honors Undergraduate Theses
Current therapy for arthritis predominantly focuses on the symptoms rather than the underlying causes of disease progression. Thus, it is necessary to identify novel drugs which target the underlying molecular basis of such diseases. Using high-throughput cell-based drug screening, we screened 458 different compounds, narrowed down from 811 starting compounds from the NIH Mechanistic Set. We selected drugs from the Mechanistic Set following Lipinski's Rule of 5 to ensure optimal pharmacokinetic properties. The study used modified primary human chondrocytes (IIAM-PRG4Luc), which secrete a lubricin promoter-driven luciferase reporter. We use this luciferase expression as a proxy to measure lubricin, a compound …

Theses and Dissertations--Medical Sciences
Protein Arginine Methyltransferase 5 (PRMT5) is a member of PRMT family that controls both intrinsic and extrinsic oncogenic processes [1]. Protein arginine methyltransferase 5 (PRMT5) is a type II methyltransferase that exerts widespread influence over gene expression, splicing, DNA repair, and immune regulation through symmetric dimethylation of arginine residues on histone and non-histone proteins [2]. The addition of methyl groups induces gene silencing through producing dictatorial histone marks like H2AR3ne2s, H3R8me2s and H4R3mes [3], which act as epigenetic repressive marks on gene promoters. In non-histone proteins, PRMT5 can methylate and regulate transcription factor proteins such as p53, E2F1, and p65, …

The alarmingly high prevalence of obesity in older adults coupled with the negative health effects of chronic inflammation in both obesity and aging highlight the importance of studies investigating the impacts of obesity on age-related inflammation. Since shifts in peripheral T-cell metabolism and function drive systemic inflammation in both obesity and aging, we hypothesize that obesity impacts the Th17-dominated inflammaging profile we identified in lean subjects and thus modifies the anti-inflammatory effects of geroprotective drugs like metformin.

Bilirubin, a metabolite derived from heme degradation, has traditionally been regarded as a waste product and a marker of liver injury. However, increasing evidence suggests that bilirubin also functions as a hormone, and reduced levels are associated with metabolic dysfunction. Studies have shown a strong association between low circulating bilirubin levels and an increased risk of metabolic disorders and cardiovascular disease. To advance bilirubin-based treatment strategies, it is essential to elucidate the mechanisms underlying bilirubin transport and metabolism. Therefore, we provide an in-depth discussion of bilirubin production and its subsequent fates, with a particular focus on the transport between the …
