The Role Of The Nlrp3 Inflammasome In Preeclampsia And Implantation Failure: A Molecular Review, Ari Budi Suryawinata, Mariel Tania Darmayani, Listyani Suhargo

Chulalongkorn Medical Journal

The NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome is a critical multiprotein complex of the innate immune system that functions as a molecular sensor for a wide array of danger signals. While its activation is essential for host defense and tissue homeostasis, its dysregulation is increasingly implicated in the pathophysiology of numerous inflammatory disorders. This review article synthesizes the current molecular understanding of the NLRP3 inflammasome, focusing on its dual role in health and disease. We first provide a concise overview of the canonical two-step mechanism of NLRP3 activation and the intricate molecular checkpoints including genetic factors, post-translational …

Subunit Composition Of The Katp Channels That Modulate Contractility Of Skeletal Muscle During Fatigue, Rosa Scala, Yuezhou Chen, Berk Mizrak, Gretchen A Meyer, Colin G Nichols

2020-Current year OA Pubs

ATP-sensitive potassium (KATP) channels are among the most expressed ion channels in skeletal muscle sarcolemma. While all KATP subunits can be detected in skeletal muscles, transcripts are enriched for KCNJ11 and ABCC9, suggesting that noncanonical Kir6.2/SUR2A assembly may constitute the majority of sarcolemmal KATP channels, but there has been no systematic dissection of KATP makeup in skeletal muscles. Here, we used a unique collection of murine lines selectively lacking specific channel-forming subunits (knockout, KO), and combined a genetic and pharmacological approach to determine which subunits of KATP channels are functionally relevant for skeletal muscle contraction. Under fatiguing conditions, isometric tetanic …

A Conserved Mechanism For Dimerization And Activation Of Superfamily 1a Uvrd-Family Helicases, Binh Nguyen, Kacey N Mersch, Ankita Chadda, Eric A Galburt, Timothy M Lohman

2020-Current year OA Pubs

DNA helicases are ATP-dependent motor proteins that catalyze duplex DNA unwinding and are involved in DNA repair, recombination, and replication restart. Prominent members of the non-hexameric SF1A UvrD-family helicases are Escherichia coli UvrD, Rep, Bacillus stearothermophilus PcrA, and Mycobacterium tuberculosis (Mtb) UvrD1. SF1A monomers are processive 3'-to-5' single-stranded DNA translocases but need to be activated to become DNA helicases. One mechanism of activation is dimerization. Whereas Rep, UvrD, and PcrA form non-covalent dimers, the Mtb UvrD1 helicase forms a redox-dependent covalent dimer. Dimerization of Mtb UvrD1 occurs between the same regulatory domain (2B) within each subunit stabilized by a disulfide …

Aberrant Ciliogenesis Induced By Enhanced Bmp Signaling Causes Heterotopic Ossification, Hiroyuki Yamaguchi, Jianbo Wang, Fangfang Yan, Jiarui Bi, Radbod Darabi, William R. Lagor, Zhongming Zhao, Aris N. Economides, Yuji Mishina, Yoshihiro Komatsu

Faculty, Staff and Student Publications

Bone morphogenetic protein (BMP) signaling is a principal driver of heterotopic ossification (HO), yet how aberrant BMP activity structurally reprograms cellular signaling machinery to develop HO remains unclear. Here, we identify BMP signaling as a direct upstream regulator of ciliogenesis that coordinates a multi-stage, pro-osteochondrogenic signaling relay during HO. Using a conditional gain-of-function BMP mouse model (Acvr1Q207D/+), we demonstrate that enhanced BMP signaling promotes primary cilium biogenesis and axonemal elongation through canonical Smad1/5/9-dependent transcriptional activation of intraflagellar transport (IFT) Ift20, a core component of the IFT machinery. Rather than operating via a singular downstream cascade, these elongated …

Faculty, Staff and Students Publications

Transmembrane protein 63B gene (TMEM63B) encodes a mechanosensitive ion channel expressed in alveolar type II epithelial cells, where it mediates stretch-induced surfactant secretion. While heterozygous gain-of-function variants in TMEM63B have been associated with developmental and epileptic encephalopathy, no human disorder has previously been linked to bi-allelic loss-of-function variants. Here, we report five individuals from four unrelated families with childhood interstitial lung disease and bi-allelic predicted loss-of-function variants in TMEM63B. Affected individuals presented with early-onset respiratory distress, chronic hypoxemia, and diffuse parenchymal lung abnormalities on chest imaging. One individual died in infancy, two underwent bilateral lung transplantation, and two require oxygen …

Grounded in Herzberg’s motivation-hygiene theory, the purpose of this qualitative pragmatic inquiry was to explore effective workforce retention strategies used by public health leaders to retain skilled staff and strengthen organizational capacity and revenue. The participants were eight public health leaders in the Northeast region of the United States with responsibility for workforce management and …

When It’S Not Gastroparesis: Isolated Idiopathic Acth Deficiency Presenting With Recurrent Gastrointestinal Symptoms, Navya Pendyala, Md, Ramya Pendyala, Md, Anna Mathew, Md, Beatriz Torre, Md, Christopher Henry, Md

The Medicine Forum

Adrenal insufficiency is an uncommon but important cause of nonspecific gastrointestinal symptoms. We present a 33-year-old male with recurrent nausea, vomiting, and presumed gastroparesis who was ultimately found to have isolated idiopathic ACTH deficiency after discordant diagnostic findings prompted further evaluation. His symptoms resolved rapidly with glucocorticoid replacement. This case highlights the importance of considering adrenal insufficiency in patients with unexplained gastrointestinal symptoms and systemic features despite negative structural work up and underscores the role of diagnostic anchoring in delayed diagnosis.

The Medicine Forum

Urothelial cell carcinoma (UCC) with squamous differentiation (SqD) is a subtype of bladder cancer with high metastatic potential. Metastasis of muscle-invasive UCC to the GI tract, with complete transition to squamous cell carcinoma (SCC), is rare, particularly in females. We present a female patient with high grade UCC with SqD treated with radical cystectomy and immunotherapy who presented with hematochezia 1 year after her cancer treatment. Imaging and colonoscopy revealed an annular, obstructing mass in the rectosigmoid region prompting sigmoid colectomy and partial proctectomy. Histopathology revealed invasive SCC. New gastrointestinal (GI) symptoms with prior invasive bladder cancer should prompt evaluation …

Patient Perspectives On Psychiatric Polygenic Risk Scores In Reproductive Decision-Making And Polygenic Embryo Screening., Lauren A Ginn, Amanda R Merner, Page M Trotter, Kaitlynn P Craig, Abigail C Martinez, Ana Lucía Battaglino, Dorit Barlevy, Daphne M Ayton, Takahiro Soda, Eric A Storch, Gabriel Lázaro-Muñoz, Stacey Pereira

Center for Medical Ethics and Health Policy Staff Publications

Polygenic risk scores (PRS) estimate individuals' genetic risk for developing multifactorial conditions. Recent genome-wide association studies have enabled development of psychiatric PRS, which hold potential to streamline diagnosis and treatment of psychiatric conditions. As individuals with mental illness often identify concern about passing on psychiatric conditions as a key factor in family planning, some may also seek to use psychiatric PRS in reproductive decisions like childbearing or embryo selection for in vitro fertilization. Despite calls for increased regulation, there remains no clinical consensus on the utility of psychiatric PRS in reproductive contexts. Therefore, we conducted semi-structured interviews of adults with …

BACKGROUND: Hyper-inflammation is common to multiple critical care syndromes, including acute respiratory distress syndrome (ARDS) and sepsis, and is associated with worse outcomes. A signature of hyper-inflammatory ARDS has been described in adults using IL-6, TNFR1, and bicarbonate, and has prognostic utility. We investigated the application of this traditional parsimonious signature to pediatric ARDS patients and tested whether we could improve prognostic enrichment using other cytokines.

METHODS: We leveraged a prospective multicenter cohort study of 500 children with ARDS (Linking Endotypes and Outcomes in Pediatric Acute Respiratory Distress Syndrome [LEOPARDS]; NCT04113434) study. Plasma samples were obtained within 24 h of …

2020-Current year OA Pubs

OBJECTIVE: To evaluate if a single-subject study (S3) design, utilizing paired transcriptome samples from the same patient (eg, "sepsis" vs "recovered"), can replicate transcriptomic signatures from small case-control studies, addressing challenges in patient accrual for rare or sub-stratified diseases.

METHODS: We generated a sepsis gene signature (SGS) comprising 300 differentially expressed genes (DEGs; FDR <  5%) from a human sepsis case-control cohort using general linear models (GLMs). Reproducibility of SGS was assessed through three approaches applied to sub-sampled independent datasets: single-subject analyses (N-of-1-MixEnrich), anticipated to perform better; conventional paired-sample GLM analyses; and a traditional case-control GLM analysis.

RESULTS: SGS reproducibility in GLM analyses was inconsistent at smaller cohort sizes (∼80% reproducibility; n = 5) but stabilized at cohort sizes >6. Remarkably, the single-subject-study approach consistently reproduced SGS in each of the 18 subjects individually (100% reproducibility; n = 1).

DISCUSSION: Conventional GLMs are …

Improving Iv Access Outcomes In Obstetric Care Through A-Diva Scale Utilization And Point-Of-Care Ultrasound, Parth S. Patel, Matthew T. Komorowski

Doctor of Nurse Anesthesia Practice (DNAP) Manuscripts

Obstetric (OB) patients frequently present physiological changes, including edema, obesity, and peripheral vasoconstriction, that increase the risk of difficult intravenous access (DIVA). Multiple IV attempts can delay time-sensitive therapies in obstetric emergencies and increase patient discomfort and provider workload. Research studies have supported the use of the Modified Adult Difficult Intravenous Access (A-DIVA) scale to assess patients for DIVA, and the use of point-of-care ultrasound (POCUS) guided peripheral intravenous access (PIVA). In 2025, a preceding Doctor of Nurse Anesthesia Practice (DNAP) project implemented A-DIVA in the Labor & Delivery (L&D) unit of an OB department and found that 35% of …

High-Throughput Quantitation Of Pathogen-Induced Calcium Signals Captured Through Live-Cell Fluorescence Microscopy, J Thomas Gebert, Ethan M Huleatt, Francesca J Scribano, Michael R Eledge, Lauren E Dorn, Sammy K Hasmi, Joseph M Hyser

Faculty, Staff and Students Publications

Many intracellular pathogens manipulate host cell calcium to facilitate their survival and replication. Live-cell microscopy using fluorescent calcium indicators has become an indispensable tool for characterizing the mechanisms underlying both homeostatic and pathogen-induced cellular calcium dynamics, but such imaging must be coupled with robust quantitative analysis. Further, calcium imaging is most powerful when paired with reductive studies targeting calcium-modulating proteins. The lack of specific inhibitors or agonists to directly target most pathogen-induced calcium signals precludes many of the approaches that have allowed for robust characterization of major eukaryotic cell calcium signaling mechanisms, such as ER Ca2+ release by inositol triphosphate …

Mechanisms Coordinating Exit From The Stem Cell State In Mammals, Emily J Park, Florencia Levin-Ferreyra, Bruno Di Stefano

Faculty, Staff and Students Publications

Differentiation requires coordinated exit from the stem cell state, during which gene regulatory networks sustaining self-renewal are dismantled, while lineage-specific programs are activated. This transition is governed by chromatin modifications, transcriptional networks, RNA processing, translational control, and metabolic rewiring that must operate with temporal precision. Despite significant progress in identifying individual regulatory components, understanding how these layers integrate to orchestrate irreversible cell fate commitment remains a fundamental challenge. This review examines common and unique regulatory principles governing stem cell exit, from totipotency during early embryogenesis to tissue-specific stem cell differentiation in adults. We synthesize recent findings on regulatory mechanisms across …
