Background: Primary hypertension in childhood tracks into adulthood and is associated with increased cardiovascular risk. Studies conducted in individuals aged < 18 years, an age group without many of the confounding comorbid cardiovascular disease risk factors in adults, provide an opportunity to explore early cardiovascular target-organ injury.

Methods: Youths (n=132, mean age, 15.8 years) were stratified by blood pressure (BP) as low-BP, mid-BP, and high-BP and by left ventricular mass index as low-and high left ventricular mass index. Systemic circulating RNA, microRNA, and methylation profiles in peripheral blood mononuclear cells and deep proteome profiles in serum were determined using high-throughput sequencing techniques. In vitro cell culture experiments assessed angiotensin II- and microRNA-mediated Vash1 (vasohibin-1 protein) regulation and Vash1-mediated hypertrophic response.

Results: In high-BP youths, transcriptomics analysis identified …

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 …

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 …

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 …

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.

2020-Current year OA Pubs

BACKGROUND: Physical activity is associated with lower colorectal cancer (CRC) risk, but its association with molecular subtypes defined by genetic and epigenetic alterations of the disease is unclear. Such information may enhance the understanding of the mechanisms related to the benefits of physical activity.

METHODS: Pooled observational (cases: n = 5386; controls: n = 6798; studies n = 5) and genome-wide association data (cases: n = 8178; controls: n = 10 472; studies n = 5) were used. We used multivariable logistic regression models and Mendelian randomization to assess the association between physical activity and the risk of CRC subtypes …

Pip2-Driven Cytoplasmic Domain Motions Are Coupled To Kir2 Channel Gating, Eva-Maria Zangerl-Plessl, Anna Stary-Weinzinger, Colin G Nichols, Sun-Joo Lee

2020-Current year OA Pubs

Inwardly rectifying potassium (Kir) channel activity is important in the control of membrane potentials in both excitable and non-excitable cells and is regulated through various ligands, including specific membrane lipids. Phosphatidyl-4,5-bisphosphate (PIP2) is required for activity of all Kir channels, binding to the cytoplasmic domain in a compact conformation tightly tethered to the transmembrane domain. Most Kir2 channel structures determined in complex with PIP2 molecules are nevertheless in a closed state, requiring additional conformational changes for channel opening. We have carried out full atomistic MD simulations, which indicate PIP2-dependent conformational changes that are coupled to opening and closing of the …

Muscle Fatigue Arising Intrinsically From Sur2- But Not Kir6.1-Dependent Gain-Of-Function In Cantu Syndrome Mice, Rosa Scala, Maya Mukadam, Yuezhou Chen, Courtney Frazier, Nathaniel W York, Robert C Tryon, Gretchen A Meyer, Colin G Nichols

2020-Current year OA Pubs

Cantu syndrome (CS) is a rare disease caused by gain-of-function (GOF) mutations of Kir6.1 or SUR2 subunits of ATP-sensitive potassium (KATP) channels. CS patients with SUR2 and Kir6.1 variants display a similar constellation of symptoms, including muscle weakness and fatigue. The effects of CS mutations on skeletal muscle KATP channels, and any consequent direct effects on contractility, are currently unclear. Here, we used two knock-in mouse models of CS, respectively, carrying GOF mutations Kir6.1[V65M] or SUR2[A478V], to assess KATP channel properties and contractility in isolated fast-twitch extensor digitorum longus (EDL) and slow-twitch soleus (SOL) muscles. Electrophysiological recordings in isolated myofibers …

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 …

2020-Current year OA Pubs

Mutations that initiate acute myeloid leukemia (AML) can cause clonal expansion without transformation (clonal hematopoiesis). Cooperating mutations, usually in signaling genes, are needed to cause overt disease, but these may require a specific fitness state to be tolerated. Here, we show that nearly all AMLs arising in a mouse model expressing 2 common AML-initiating mutations (Dnmt3aR878H and Npm1cA) acquired a single copy amplification of chromosome 7 (chr7), followed by activating mutations in signaling genes. We show that overexpression of a single gene on chr7 (Gab2, which coordinates signaling pathways) was tolerated in the presence of the Npm1cA mutation, could accelerate …

A Temperature-Sensitive Crispr-Cas12a System For Sterile Insect Technique, Christina Nguyen, Ahmed Idowu Omotayo, Sara Sanz Juste, Xuechun Feng, Víctor López Del Amo

Faculty, Staff and Student Publications

The sterile insect technique (SIT) reduces population numbers by releasing sterile males that produce non-viable progeny. Specifically, CRISPR/Cas9-based precision-guided SIT (pgSIT) generates sterile males through genetic crosses of two transgenic lines: a Cas9 strain and a guide RNA (gRNA) strain targeting male sterility and female viability or infertility. However, pgSIT requires separate maintenance of the two lines and sorting to obtain sterile males, creating possible challenges for scaling. To overcome this, we propose using Cas12a nuclease, which is inoperative at lower temperatures but active at higher temperatures. Here, we develop a Cas12a-based pgSIT system involving a single strain containing both …

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 …

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 …

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 …

Orphan Nuclear Receptor 4a1 (Nr4a1) And Nr4a2 Are Endogenous Regulators Of Cd71 And Their Ligands Induce Ferroptosis In Breast Cancer, Arafat Rahman Oany, Srijana Upadhyay, Wai Ning Tiffany Tsui, Amanuel Hailemariam, Sarah Latka, John D Landua, Sandra D Scherer, Alana L Welm, Hugo Villanueva, Michael T Lewis, Stephen Safe

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 …
