Childhood trauma is a risk factor for bipolar disorder, but the biological mechanisms of this association remain incompletely defined. Gray matter differences observed after trauma exposure overlap with those reported in bipolar disorder, suggesting that the association between childhood trauma and bipolar disorder might be mediated through brain morphology.

Our goal was to determine whether cortical thickness, cortical surface or subcortical volume mediate the association between childhood trauma and bipolar disorder. We leveraged a large multi-site dataset from the ENIGMA Bipolar Disorder Working Group, comprising of 1,031 participants with bipolar disorder and 2,221 controls from 19 international cohorts. To identify …

Pregnancy requires a supportive uterine environment facilitated by steroid hormone–regulated differentiation of endometrial stromal fibroblasts into decidual cells and tight control of inflammation. Serum response factor (SRF) is a widely expressed transcription factor essential for mesenchymal cell growth and differentiation with noted roles in hormonal regulation of muscle tissues but little characterization in reproductive organs. Here, we reveal that endometrial SRF is dysregulated in human endometriosis and is critical for female reproductive success in mice through regulation of endometrial stromal and epithelial cells. Immunohistochemical analysis identified decreased endometrial SRF expression in infertile endometriosis patient tissues. RNAi-based SRF knockdown in human …

During cancer development, mutations promote changes in gene expression that cause transformation. Leukemia associated with aberrant HOXA expression is driven by translocations of nucleoporin genes or KMT2A as well as mutations in NPM1. The mechanistic convergence of these disparate mutations remains elusive. Here, we demonstrate that mutant nucleophosmin 1 (NPM1c) forms nuclear condensates in human cell lines, mouse models, and primary patient samples. We show NPM1c phase separation is necessary and sufficient to recruit NUP98 and KMT2A to condensates. Through extensive mutagenesis and pharmacological destabilization of phase separation, we find that NPM1c condensates are necessary for regulating gene expression, promoting …

Elucidating The Relationship Between Water Quality And Antibiotic Resistance Of Rainwater Microbes Across Western Humboldt County, Theo P. Murphy, Eve Wendley, Justice Laskowski, Tyler Paredes

Humboldt Journal of Microbiology

Limited studies have been conducted regarding the fecal contamination and microbial dispersal through rainwater, with no known studies investigating the potential connection between antibiotic resistant microbes and water quality in rainwater. This study seeks to identify the presence of a correlation between water quality and incidence of antibiotic resistance in rainwater microbes. We hypothesize that there will be a correlation between these two variables. We additionally anticipate a high incidence of fecal contamination across rural and urban collection sites alike, with fecal contamination being more prevalent in rural areas than urban locals. To determine water quality, we measured the concentration …

Accidental Daily Dosing: Severe Methotrexate Toxicity In A Patient With Rheumatoid Arthritis, Sidra Memon, Kavitha Vemuri, Syed Uzair Mahmood, Darshit Patel

Advances in Clinical Medical Research and Healthcare Delivery

This case highlights a crucial complication of oral methotrexate therapy: toxicity due to dosing errors. A patient’s daily dosing regimen, instead of the intended weekly schedule, led to a significantly excessive cumulative dose of methotrexate over a short period, resulting in severe hematologic and mucosal toxicity. This underscores the importance of clear patient education and vigilant prescription practices to prevent such errors.

Human Kallikrein 2: A Novel Lineage-Specific Surface Target In Prostate Cancer, Fei Shen, Ryan Smith, Theresa Mcdevitt, Krista Menard, Shaozhou Tian, Gerald Chu, Ruchi Chaudhary, Jennifer Mccann, Halley Oyer, Sherry C. Wang, Steven Max, Peter Francis, William K. Kelly, Charles G. Drake

Kimmel Cancer Center Faculty Papers

PURPOSE: Targeted therapies for metastatic prostate cancer are limited, highlighting the need for novel drug targets and mechanisms of action (MoA). Human kallikrein 2 (KLK2) is a prostate-specific antigen expressed across the prostate cancer disease continuum. However, it was not recognized as a therapeutic target for prostate cancer in the past due to limited evidence of its cell surface expression. In this study, we systematically characterized KLK2 expression in prostate cancer, confirmed its cell surface expression, and demonstrated the preclinical efficacy of three KLK2-targeting therapeutics with distinct MoA.

EXPERIMENTAL DESIGN: The KLK2 expression profile in different stages of prostate cancer …

Wills Eye Hospital Papers

PURPOSE: Leiomyomas are benign smooth muscle tumors that commonly present in the uterus, soft tissue, skin, and gastrointestinal tract but in rare cases can also arise within the eye. Notably, intraocular leiomyomas often show slightly different histopathologic and immunohistochemical features, referred to as mesectodermal morphology, given their presumed neural crest origin. Genetic and cytogenetic alterations of intraocular leiomyomas, as well as their association with various clinical and histopathologic features, have not been previously studied.

METHODS: We identified eight patients diagnosed with intraocular leiomyoma and performed targeted next-generation sequencing, whole transcriptome RNA sequencing, and chromosomal copy number analysis on those with …

Preclinical Fluorescence-Guided Imaging Leveraging Surrounding Sentinel Tumor Microenvironment Identifies High-Risk Premalignant Pancreatic Lesions, Shilpa Sharma, Xiaoxia Wen, Jianbo Wang, Beibei Huang, Denise A Hernandez, Cong-Dat Pham, Zhiwen Liu, Susanne Je-Han Lin, Aiko Yamaguchi, Dimitra K Georgiou, Ryan P Coll, H Charles Manning

Faculty, Staff and Student Publications

Purpose: Because surgery is the only potential cure for pancreatic cancer, high-risk premalignant pancreatic lesions often evade detection by palpation or white-light visualization, increasing the risk of recurrence. We asked whether near-infrared fluorescence imaging of tumor-associated inflammation could identify high-risk premalignant lesions, leveraging the tumor microenvironment as a sentinel of local disease and, thus, enhance surgery outcomes.

Experimental design: Fluorescence-guided surgery was performed on genetically engineered mice [Ptf1a-Cre; LSL-KrasG12D/+; Smad4flox/flox (KSC)] at discrete stages of disease progression, histologically confirmed high-risk, premalignant lesions in postnatal mice to locally advanced pancreatic tumors in adults, using the imaging agent V-1520, a translocator protein …

Background: Dyslipidemia can occur as a long-term side effect of childhood cancer treatment. The difference in prevalence among children receiving comparable treatment suggests a role for genetic variation. We conducted the first genome-wide association study on dyslipidemia in a large childhood cancer survivor cohort, using three additional cohorts for replication.

Methods: Discovery analysis was performed in the original Childhood Cancer Survivor Study (CCSS) cohort (N = 4,332). Replication analyses were carried out in the CCSS expansion (N = 2,212), St. Jude Lifetime (N = 2,829), and Dutch Childhood Cancer Survivor Study (DCCSS-LATER) (N = 1,814) cohorts. In the CCSS cohorts, …

Triple-negative breast cancer (TNBC) that fails to respond to neoadjuvant chemotherapy (NACT) can be lethal. Developing effective strategies to eradicate chemoresistant disease requires experimental models that recapitulate the heterogeneity characteristic of TNBC. To that end, we established a biobank of 92 orthotopic patient-derived xenograft (PDX) models of TNBC from the tumors of 75 patients enrolled in the ARTEMIS clinical trial (NCT02276443), including 12 longitudinal sets generated from serial patient biopsies collected throughout NACT treatment and from metastatic disease. Models were established from both chemosensitive and chemoresistant tumors, and nearly 30% of the PDX models were capable of metastasizing …

Faculty, Staff and Students Publications

Ferroptosis is an iron-dependent cell death pathway that involves multiple genes, including the transferrin receptor (TFRC/CD71), glutathione peroxidase 4 (GPX4) and cystine-glutamate antiporter (SLC7A11). This study is based on the hypothesis that orphan nuclear receptor 4A1 (NR4A1) and NR4A2 maintain low levels of ferroptosis in triple negative breast cancer (TNBC) cells and bis-indole derived (CDIM) compounds act as NR4A1/2 ligands that induce ferroptosis by enhancing CD71 expression. 1,1-Bis(3'-indolyl)-1-(3,5-disubstitutedphenyl)methane (DIM-3,5) analogs were investigated for their cytotoxicity and effects on NR4A1 and NR4A2 regulated genes and induction of ferroptosis. Several assays also determined enhanced lipoperoxidation, reactive oxygen species and malondialdehyde formation in …

Leptomeningeal metastases are the most important source of morbidity and mortality for medulloblastoma patients. Radiation of the entire brain is highly effective in the treatment and/or prevention of medulloblastoma leptomeningeal metastases. Infants treated on clinical trials with focal tumor radiation recur metastatically, whereas infants treated with only chemotherapy relapse locally. In murine medulloblastoma model systems, provision of a single dose of radiation to the tumor drives leptomeningeal dissemination. An inflammatory response after radiation-induced tumor cell death recruits a variety of immune cells. Inflammation opens the local blood-brain barrier, allowing intravasation of medulloblastoma cells. Experimental induction of inflammation with lipopolysaccharide drives …

Developing Optogenetic Approaches To Study Ca2+ Signaling Processes, Tatsuki Nonomura, Xiaoxuan Liu, Megan Chiu, Zhi Tan, Tien-Hung Lan, Yubin Zhou

Faculty, Staff and Students Publications

Calcium ions (Ca2+) are essential second messengers intimately implicated in a variety of biological processes, ranging from short-term events such as muscle contraction to long-term effects like gene expression. Dysregulated Ca2+ signaling can disrupt cellular function and contribute to the development of various human diseases, including developmental, neurological, immunoinflammatory, metabolic, and cardiovascular disorders. To study the mechanisms and biological consequences of Ca2+ signaling, optogenetic approaches have proven invaluable, as they offer exceptional spatiotemporal resolution compared to traditional methods. Recent progress in non-opsin-based optogenetics, particularly those engineered from Ca2+ release–activated Ca2+ (CRAC) channels, has substantially advanced our understanding of Ca2+ signaling …

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer with few effective targeted therapies. Taxanes and other microtubule-targeting agents (MTAs) are frontline chemotherapies for TNBC; however, the molecular pathways that cause TNBC taxane sensitivity are largely unknown, preventing selection of taxane-responsive patients and development of more selective therapeutic strategies. In this study, we identified tumor-selective vulnerabilities in TNBC harboring inactivation of the tumor suppressor PTPN12 by integrating proteogenomic characterization and synthetic lethality screening. We discovered that PTPN12 inactivation drives mitotic defects through aberrant hyperactivation of the ubiquitin ligase complex APCFZR1, a critical regulator of the cell cycle. Consistent …

Proteomic Perspectives On Kras-Driven Cancers And Emerging Therapeutic Approaches, Ramesh Karki, Ru Chen, Sheng Pan

Faculty, Staff and Student Publications

KRAS mutations are implicated in approximately 23% of all human malignancies, with particularly high prevalence in pancreatic ductal adenocarcinoma (PDAC) (~92%), colorectal cancer (CRC) (~49%), and non-small cell lung cancer (NSCLC) (~35%). The recent approval of the KRASG12C-specific inhibitors for NSCLC represents a pivotal advancement in KRAS-targeted therapy. Nevertheless, the emergence of intrinsic and acquired resistance to KRAS-targeted therapies poses a significant clinical obstacle to targeting KRAS, which necessitates a deeper understanding of the resistance mechanisms. Recent progress in proteomic studies has enabled comprehensive profiling of the proteomic alterations driven by KRAS mutations, offering valuable insights into the disrupted KRAS …

Real-World Impact Of Amiodarone On Apixaban Population Pharmacokinetics In Hospitalized Patients, Samantha Kolowrat, Chazmyn Riley, Kevin Lam, Lynda Thomson, Douglas F. Stickle, Walter K. Kraft

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Despite common coadministration in nonvalvular atrial fibrillation (NVAF), there is minimal evidence regarding the impact of concomitant amiodarone use on apixaban pharmacokinetics (PK). We described the population PK of apixaban (2.5 and 5mg twice daily) in 106 hospitalized patients with and without concomitant amiodarone administration at steady state. Apixaban PK was reasonably described by a one-compartment model with first-order absorption and linear elimination. Aside from the receipt of amiodarone, age was retained as a statistically significant covariate on apparent clearance. Model-based simulations depicted concomitant amiodarone use increasing AUCT for both 2.5mg (1.58, 90% CI [1.28, 1.87]) and 5mg (1.12, 90% …

Concerns Regarding The Standard Deviation Of Individual Responses For Assessing Treatment Response Heterogeneity, Aaron R Caldwell, David B Allison, Andrew W Brown, Gary L Gadbury, Thirupathi Reddy Mokalla, R Drew Sayer, Andrew D Vigotsky

Children’s Nutrition Research Center Staff Publications

The estimation of treatment response heterogeneity (TRH) is increasingly important as medicine moves toward personalized approaches. While various statistical methods have been proposed to quantify TRH in parallel-group trials, the standard deviation of individual responses (SDIR) has gained prominence within physiological research. This method is intended to quantify individual response variation by comparing standard deviations of change scores between intervention and control groups. We acknowledge that SDIR represents an improvement over many other flawed approaches that often involve responder counting. However, SDIR has critical limitations: 1) it cannot overcome the fundamental problem of causal inference because the correlation between potential …

Restricting Metabolic Plasticity Enhances Stress Adaptation Through The Modulation Of Pdh And Hif1a In Trap1-Depleted Colon Cancer, Hong-Yuan Tsai, Miao-Hsueh Chen, Jihye Yun, Lisa A Lai, John F Valentine, Mary P Bronner, Teresa A Brentnall, Sheng Pan, Ru Chen

Faculty, Staff and Student Publications

Metabolic plasticity allows cancer cells to survive under adverse conditions. To investigate the role of mitochondrial chaperone tumor necrosis factor receptor-associated protein 1 (TRAP1) in this process, we used CRISPR/Cas9 mediated genetic deletion to knock out (KO) TRAP1 in colon cancer cells. Depletion of TRAP1 triggered a series of events: induced metabolic reprogramming, increased glycolytic flux, downregulation of mitochondrial complex I, and elevated ROS generation. TRAP1-deficient cells showed tolerance to Oxidative Phosphorylation (OXPHOS) inhibitors and exhibited a higher extracellular acidification rate (ECAR). Additionally, TRAP1 depletion activated hypoxia response elements (HREs) and upregulated HIF1A target genes such as GLUT1 and MCT1. …

The Genomes Of Nematode-Trapping Fungi Provide Insights Into The Origin And Diversification Of Fungal Carnivorism, Yani Fan, Minghao Du, Weiwei Zhang, Wei Deng, Ence Yang, Shunxian Wang, Luwen Yan, Liao Zhang, Seogchan Kang, Jacob L Steenwyk, Zhiqiang An, Xingzhong Liu, Meichun Xiang

The Brown Foundation: Institute of Molecular Medicine

Nematode-trapping fungi (NTF), most of which belong to a monophyletic lineage in Ascomycota, cannibalize nematodes and other microscopic animals, raising questions regarding the types and mechanisms of genomic changes that enabled carnivorism and adaptation to the carbon-rich and nitrogen-poor environment created by the Permian-Triassic extinction event. To address these questions, we conducted comparative genomic analyses of 21 NTF and 21 non-NTF. Carnivorism-associated changes include expanded genes for nematode capture, infection, and consumption (e.g., adhesive proteins, CAP superfamily, eukaryotic aspartyl proteases, and serine-type peptidases). Although the link between secondary metabolite (SM) production and carnivorism remains unclear, we found that the number …

Gliomas and brain metastases are associated with poor prognosis, necessitating a deeper understanding of brain tumor biology and the development of effective therapeutic strategies. Although our group and others have demonstrated microbial presence in various tumors, recent controversies regarding cancer-type-specific intratumoral microbiota emphasize the importance of rigorous, orthogonal validation. This prospective, multi-institutional study included a total of 243 samples from 221 patients, comprising 168 glioma and brain metastases samples and 75 non-cancerous or tumor-adjacent tissues. Using stringent fluorescence in situ hybridization, immunohistochemistry and high-resolution spatial imaging, we detected intracellular bacterial 16S rRNA and lipopolysaccharides in both glioma and brain metastases …

Targeting The Hippo Pathway For Cardiac Regeneration, Rich Gang Li, Fansen Meng, James F Martin

Faculty, Staff and Students Publications

Ischemic heart disease, which affects more than 200 million people worldwide, is caused by reduced blood flow to the heart and leads to widespread cardiomyocyte death. Due to the limited regenerative potential of cardiomyocytes, the lost tissue is replaced by a fibrotic scar, resulting in reduced cardiac function and progression to heart failure. Current therapeutic interventions aim to improve blood flow but cannot address the inability of cardiomyocytes to renew after injury. However, multiple studies have shown that modulating the Hippo signaling pathway to activate Yes-associated protein (YAP), a transcription coactivator, in adult murine and porcine cardiomyocytes induces robust cardiomyocyte …
