Many individuals with epilepsy often develop major depressive disorder (MDD), creating a complex interplay that exacerbates outcomes for affected individuals. The relationship between these disorders may be mediated by overlapping neurobiological mechanisms, including disturbances in the limbic system, neurotransmitter imbalances, and the psychosocial stressors of chronic illness. While the co-occurrence typically leads to a worsening of symptoms, rare instances have been reported in which seizure activity appears to ameliorate psychiatric symptomatology. We present the case of a 23-year-old pregnant Hispanic female with a longstanding history of treatment-resistant depression with psychotic features and epilepsy, who demonstrated full remission of depressive and …

Vitamin D–mediated regulation of antimicrobial peptides (AMPs) is an important focus in innate immunology and is aimed at elucidating the role of vitamin D in enhancing antimicrobial defense. AMPs are short protein chains that serve as a first line of defense against invading pathogens, including fungi, bacteria and viruses. Unlike conventional antibiotics, AMPs are produced endogenously and are less likely to induce antimicrobial resistance, making them promising candidates for treating infections caused by drug-resistant pathogens. Studies indicate that optimal vitamin D levels are essential for activating antimicrobial pathways and regulating AMPs that target multiple fungal pathogens. This article summarizes recent …

Calcium Signaling And Postsynaptic Density Dynamics: The Roles Of Calmodulin In Synaptic Protein Regulation, Keyaa Dilip Shah, Yonghong Zhang

School of Integrative Biological & Chemical Sciences Faculty Publications

Calcium signaling in neuronal cells is the principal mechanism underlying learning and synaptic plasticity, whereas the postsynaptic density (PSD) is an important center where calcium-dependent processes are organized and regulated. This review explores the roles of calmodulin (CaM) in facilitating calcium-dependent modulation of the activities of synaptic proteins in the PSD. We focus on the molecular processes through which CaM interacts with calcium signals to regulate the function, localization, and interactions of central synaptic proteins, including calcium/calmodulin-dependent protein kinase II (CaMKII), membrane-associated guanylate kinases (MAGUKs), and N-methyl-D-aspartate (NMDA) receptors. We aim to summarize recent advances in structural, biochemical, and imaging …

Anaplastic thyroid cancer (ATC) is highly lethal. Although patients with the BRAFV600E alteration respond to the type I RAF inhibitor (RAFi) dabrafenib with trametinib, most rapidly develop adaptive or acquired resistance. Here, multi-region whole-genome, high-coverage whole-exome, and single-nuclei RNA sequencing of tumors from ATC patients undergoing type I RAFi and MEKi therapy reveals that reactivation of the mitogen-activated protein kinase (MAPK) pathway, along with immunosuppressive macrophage proliferation, may underlie the development of acquired resistance. Screening of several RAFi reveals that ATC cell lines are exquisitely sensitive to the type II RAFi naporafenib, which inhibits EphA2-mediated MAPK signaling. Further, naporafenib and …

Translational equity means ensuring that diagnostics, treatments, care models, and prevention strategies are developed and implemented so they work for populations with the greatest burden and least access to care. In Alzheimer's disease and related dementias (ADRD), where most evidence derives from highly educated, non-Hispanic White participants at large academic centers, translational equity is critical to prevent misclassification, limited access, and widening disparities and to ensure that underrepresented communities shape how new knowledge moves into practice. Hispanic and other populations in the United States are disproportionately affected by ADRD yet remain underrepresented in research, with gaps especially pronounced in high-poverty …

Health & Biomedical Sciences Faculty Publications

Despite improvements in life expectancy, people with HIV (PWH) are at risk of developing HIV-associated comorbidities at a younger age when compared to HIV-uninfected individuals. This premature aging process can be attributed to various factors, such as the prolonged exposure to combination antiretroviral therapy (cART), inflammation, microbial perturbances and oxidative stress. Similarly to the gut, oral dysbiosis occurs in HIV-1 infection, with cART and inflammation playing a crucial role. This gives rise to an enrichment of pathogenic microorganisms that in turn, elicit an immune response tied to chronic inflammation. Consequently, cART exposure, dysbiosis and persistent inflammation in HIV-1 infection have …

Acquired Left Ventricular Noncompaction Physiology In Lupus Myocarditis: An Unclassified Cardiomyopathy Phenotype, Ripudaman Singh, Eduardo D. Flores Md, Facc

Research Symposium

Background: Left ventricular noncompaction (LVNC) is a rare structural abnormality of the left ventricular myocardium, characterized by prominent trabeculations and deep intertrabecular recesses due to incomplete compaction during embryogenesis. Clinical presentation is highly variable, ranging from asymptomatic cases to arrhythmias, thromboembolism, heart failure, and sudden cardiac death. Diagnosis is primarily imaging-based, with transthoracic echocardiography (TTE) using the Jenni criteria as standard. These criteria include excessive apical or midventricular trabeculations with a noncompacted-to-compacted ratio >2:1 at end-systole, a thin compacted epicardial layer (≤8.1 mm), and color Doppler flow within the recesses. When echocardiography is inconclusive, cardiovascular magnetic resonance (CMR) is recommended. …

Abiraterone-Induced Resistant Hypokalemia And Hypertension: A Preventable Complication, Ripudaman Singh, Seokwon Choi, Aramide Tijani, Fatimah Bello

Research Symposium

Background: Abiraterone, a cytochrome P17 (17a-hydroxylase/C17,20-lyase) inhibitor used in metastatic castration-resistant prostate cancer (CRPC), suppresses androgen and cortisol synthesis, leading to elevated ACTH and accumulation of mineralocorticoid precursors such as 11-deoxycorticosterone and corticosterone, both possessing potent mineralocorticoid activity1,2,3. Concomitant prednisone is recommended to prevent this cascade, as its omission can lead to clinically significant mineralocorticoid excess manifesting as severe hypokalemia, hypertension, and fluid retention4. This preventable complication remains underrecognized, particularly in elderly patients who are frequently exposed to polypharmacy. Here, we report a patient with metastatic CRPC on abiraterone therapy who presented with acute wrist pain, …

Research Symposium

Background: Mucin 13 (MUC13), a transmembrane glycoprotein, plays a crucial role in the progression of epithelial cancers, particularly liver and pancreatic cancers. It is frequently overexpressed in malignant cells, disrupting cellular adhesion and facilitating invasive behavior. The extracellular domain and phosphorylation potential in its cytoplasmic region connect MUC13 to oncogenic signaling pathways, making it a valuable target for immunotherapy. However, challenges such as the immunosuppressive tumor microenvironment remain significant obstacles, and addressing these issues in the lab is challenging without computational intervention. To address this, we have employed an in-silico approach to design CD8+ T-cell multi-epitopes targeting MUC13 HLA class …

Global reporting of obesity is commonly based on comparisons over multiple decades1 and lacks a granular and systematic analysis of its dynamics. We used 4,050 population-based studies with measured height and weight data on 232 million participants to assess the worldwide dynamics of obesity from 1980 to 2024. The rise in obesity decelerated in school-aged children and adolescents throughout the 1990s in many high-income countries, and subsequently plateaued in most at age-standardized prevalences spanning 20 percentage points, from 3–4% for girls in Japan, Denmark and France to 23% for boys in the USA. There were indications of a small …


Phosphate-Mediated Regulation Of Intracellular Calcium Dynamics, Huma Shahzad, Mohammed S. Razzaque May 2026

Phosphate-Mediated Regulation Of Intracellular Calcium Dynamics, Huma Shahzad, Mohammed S. Razzaque

School of Medicine Publications

Phosphate (Pi) and calcium (Ca2+) are essential mineral ions that play coordinated roles in maintaining normal cellular functions. While various steps of calcium signaling are well characterized, emerging evidence suggests the critical role of both intracellular and extra cellular phosphate in regulating intracellular Ca2+. In the cytoplasm, phosphate influences ATP production and organelle calcium buffering and influences the activity of calcium pumps, such as sarcoplasmic/endoplasmic reticulum Ca2+-ATPase (SERCA) and the plasma membrane Ca2+-ATPase (PMCA). Extracellular phosphate, taken up via sodium-dependent phosphate transporters, triggers signaling cascades that affect the processes of calcium influx, storage, and release. Additionally, high extracellular phosphate levels …

CNS involvement typically presents with nonspecific symptoms such as headache, nausea, or cranial neuropathies; isolated, abrupt vision loss is rare. With a median survival of less than six months if untreated, timely recognition is critical. We present a case of intracranial hypertension with bilateral vision loss due to leukemic …
