Sultan Qaboos University Medical Journal

The management of Crohn’s disease (CD) using anti-tumour necrosis factor therapy in tuberculosis (TB)-endemic regions poses major clinical challenges due to the risk of latent TB infection reactivation. This bibliometric–systematic literature review synthesised evidence from 17 peer-reviewed studies (2020–2025) evaluating adalimumab administered with concurrent prophylactic antitubercular therapy. Thematic synthesis and bibliometric mapping using VOSviewer demonstrated that adalimumab achieved 60–85% clinical remission in moderate-to-severe CD and axial spondyloarthritis while enhancing mucosal healing. However, 1–3% of patients developed active TB despite appropriate screening and isoniazid prophylaxis, revealing false-negative diagnostics and partial chemoprophylaxis protection. These findings highlight the need for region-specific frameworks integrating …

Advances In Hpv Vaccination In People Living With Hiv: A Review, Megan Mooberry, J Brooks Jackson, Mary B Rysavy

Faculty, Staff and Student Publications

Human papillomavirus (HPV) is the most common sexually transmitted infection worldwide and is a leading cause of cervical, anal, penile, and oropharyngeal cancers. This review summarizes the epidemiology of HPV and the immunogenicity, clinical efficacy, and current HPV vaccination recommendations among people living with HIV (PLWH). PLWH experience a disproportionate burden of HPV-related infection and HPV-related malignancies. Although HPV vaccines have been shown to be highly effective, vaccination coverage among PLWH remains suboptimal, particularly in low- and middle-income countries. Barriers to vaccination include extended dosing schedules, limited awareness of the vaccine, and misinformation. Evidence indicates HPV vaccines are safe and …

Genetic Modifiers Of Apoe-Ε4-Associated Cognitive Decline, Alex G Contreras, Carlos Cruchaga, Et Al.

2020-Current year OA Pubs

The APOE-ε4 allele is the strongest genetic risk factor for late-onset Alzheimer's disease. However, APOE-ε4 is not deterministic, highlighting the need to identify additional genetic and environmental factors. APOE-ε4 has been linked to accelerated cognitive decline, so we sought to investigate genetic factors that modify APOE-ε4-associated cognitive decline. We conduct cross-ancestry APOE-ε4-stratified and interaction GWAS using harmonized cognitive data from 32,778 participants, including 29,354 non-Hispanic White and 3,424 non-Hispanic Black individuals. Our primary outcome is late-life cognition, measured using harmonized composite scores for memory, executive function, and language, modeled as continuous traits reflecting both normative cognitive aging and disease-related decline. …

Steroid Receptor Coactivators - From Basic Research To Translational Opportunities, Yosef Gilad, Sang Jun Han, David M Lonard

Faculty, Staff and Students Publications

The concept of nuclear receptor (NR) coregulation was proposed nearly two decades before it was experimentally validated. According to this model, NRs - executors of a vast array of transcriptional programs - do not act independently but are governed by a network of regulatory proteins that either activate or repress their biological function. NRs identify the genes to be regulated. However, coregulators ultimately serve as the true controllers of transcriptional outcomes. They recruit cofactors and coordinate the activity of transcriptional complexes, thereby shaping NR-mediated gene expression beyond NRs' intrinsic functionality. The Steroid Receptor Coactivator (SRC) family is the most extensively …

The Brown Foundation: Institute of Molecular Medicine

Microglia critically shape neuronal circuit development and function, yet their region-specific properties and roles in distinct circuits of the human brain remain poorly understood. In this study, we generated region-specific brain organoids (cortical, striatal, and midbrain), each integrated with human microglia, to fill this critical gap. Single-cell RNA sequencing uncovered six distinct microglial subtypes exhibiting unique regional signatures, including a subtype highly enriched for the GABAB receptor gene within striatal organoids. To investigate the contributions of microglia to neural circuitry, we created microglia-incorporated midbrain-striatal assembloids, modeling a core circuit node for many neuropsychiatric disorders, including autism. Using chemogenetics to activate …

Association Between Children’S Secondhand Co-Exposure To Tobacco And Cannabis Smoke And Elevated Urinary Cotinine Levels: A Cross-Sectional Analysis, Bradley N. Collins, Stephen J. Lepore, Vincent Berardi, Renee D. Goodwin, Karen Wilson, Mona Baishya

Psychology Faculty Articles and Research

Background Cannabis use is far more common among adults who smoke tobacco than adults who do not, and its use is increasing among people who smoke tobacco with children living in the home. Given the well-established evidence that caregiver smoking is the primary source of children’s secondhand exposures to these products, the increasing trend in caregiver co-use is raising public health concerns about children’s co-exposure. Emerging data indicates that adult co-use is linked to additive health consequences, such as elevated nicotine and other tobacco-related toxicant blood levels, relative to use of only tobacco. It is unknown whether children’s co-exposure leads …

Although BRAF/MEK inhibitor (BRAFi/MEKi) therapy initially shows high efficacy in patients with BRAFV600 E/K cutaneous melanoma, resistance develops in over 75% of cases. We tested robustness of the umbrella trial strategy in this population by analyzing relationships between genomic status of a gene and associated downstream consequences at the protein level. The results revealed weak relationships among mutations, copy-number amplification, and protein expression and activation. An in vivo compound repurposing screen using 11 clinically relevant agents from an NCI-portfolio with pan-RTK, non-RTK, and/or PI3K-mTOR specificity identified dasatinib as most capable of restoring sensitivity to BRAFi/MEKi in patient-derived xenograft (PDX) …

Faculty, Staff and Student Publications

Efficient DNA double-strand break (DSB) repair by homologous recombination (HR), as initiated by BRCA1 recruitment orchestrated by histone and non-histone proteins, is critical to genome stability, replication, transcription, and cancer avoidance. Here we reveal Heterochromatin Protein1 beta (HP1β) promotes BRCA1 enrichment at DNA DSB sites in gene-rich regions, and this is impaired by HP1β depletion. We find that HP1β is specifically enriched at DSBs within gene-rich regions via its Chromo Shadow Domain (CSD) that interacts with both Chromatin Assembly Factor 1 and the RING1A ubiquitinase component of Polycomb Repressor Complex 1. The resulting protein complex facilitates BRCA1 recruitment by promoting …

Disruption Of Proteoglycan 4 (Prg4)-Cd44 Signaling Modulates Chronic Synovitis In Conditionally Inactivated Mice, Khaled A. Elsaid, Ling Zhang, Thomas Zhao, Ava Marks, Derek Jenkins, Gregory D. Jay

Pharmacy Faculty Articles and Research

Background

Proteoglycan-4 (PRG4) is a mucinous glycoprotein secreted by synovial fibroblasts and superficial zone chondrocytes. PRG4 inhibits synovial macrophage (SM) activation via xanthine oxidase (XO) and hypoxia inducible factor alpha (HIF-1α) suppression. We aimed to evaluate the contribution of PRG4-CD44 interaction to synovial homeostasis and investigate PRG4’s signaling dysfunction in synovial tissues from patients with osteoarthritis (OA). We hypothesized that CD44 mediates synovitis due to PRG4 loss and that PRG4 signaling dysfunction is associated with high-grade synovitis in OA.

Methods

Prg4^{FrtloxP/FrtloxP} are transgenic mice wherein tamoxifen (TAM) inactivates the Frt allele and creates a knockout state (Prg4^{FrtKO/FrtKO …}

The Neuroprotective Effects Of Alpha-Tocopherol As An Anti-Inflammatory Agent: Mechanistic Insights And Therapeutic Challenges, Megumi H Seese, Yuanzhong Xu

The Brown Foundation: Institute of Molecular Medicine

Vitamin E (alpha-tocopherol, αToc), an antioxidant fat-soluble vitamin that prevents lipid peroxidation and modulates pro-inflammatory cytokine production, is well-known to be critical for neuroprotection. However, the underlying mechanism remains poorly understood. Accumulating evidence demonstrates that αToc influences neuroinflammatory processes. Here, we review recent research progress on the effects of αToc on neuroinflammation. Preclinical studies included in this narrative review were identified through PubMed searches using the keywords "alpha-tocopherol AND neuroinflammation or alpha-tocopherol AND brain AND inflammation". While many studies support a neuroprotective role of αToc, the magnitude and direction of its effects vary substantially depending on dosage, route of administration, …
