2020-Current year OA Pubs

High-grade serous ovarian cancer (HGSC) is the most lethal histotype of ovarian cancer and the majority of cases present with metastasis and late-stage disease. Over the last few decades, the overall survival for patients has not significantly improved, and there are limited targeted treatment options. We aimed to better characterize the distinctions between primary and metastatic tumors based on short- or long-term survival. We characterized 39 matched primary and metastatic tumors by whole exome and RNA sequencing. Of these, 23 were short-term (ST) survivors (overall survival (OS) < 3.5 years) and 16 were long-term (LT) survivors (OS > 5 years). We compared somatic mutations, copy number alterations, mutational burden, differential gene …

Invited Review: Adrenocortical Function In Avian And Non-Avian Reptiles: Insights From Dispersed Adrenocortical Cells., Rocco V. Carsia, Patrick J. Mcilroy, Henry B John-Alder

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Herein we review our work involving dispersed adrenocortical cells from several lizard species: the Eastern Fence Lizard (Sceloporus undulatus), Yarrow's Spiny Lizard (Sceloporus jarrovii), Striped Plateau Lizard (Sceloporus virgatus) and the Yucatán Banded Gecko (Coleonyx elegans). Early work demonstrated changes in steroidogenic function of adrenocortical cells derived from adult S. undulatus associated with seasonal interactions with sex. However, new information suggests that both sexes operate within the same steroidogenic budget over season. The observed sex effect was further explored in orchiectomized and ovariectomized lizards, some supported with exogenous testosterone. Overall, a suppressive effect of testosterone was evident, especially in cells …

The Effects Of Natural Epigenetic Therapies In 3d Ovarian Cancer And Patient-Derived Tumor Explants: New Avenues In Regulating The Cancer Secretome., Rebeca Kelly, Diego Aviles, Catriona Krisulevicz, Krystal Hunter, Lauren Krill, David Warshal, Olga Ostrovsky

Cooper Medical School of Rowan University Departmental Research

High mortality rates in ovarian cancer have been linked to recurrence, metastasis, and chemoresistant disease, which are known to involve not only genetic changes but also epigenetic aberrations. In ovarian cancer, adipose-derived stem cells from the omentum (O-ASCs) play a crucial role in supporting the tumor and its tumorigenic microenvironment, further propagating epigenetic abnormalities and dissemination of the disease. Epigallocatechin gallate (EGCG), a DNA methyltransferase inhibitor derived from green tea, and Indole-3-carbinol (I3C), a histone deacetylase inhibitor from cruciferous vegetables, carry promising effects in reprograming aberrant epigenetic modifications in cancer. Therefore, we demonstrate the action of these diet-derived compounds in …

High Extracellular Glucose Promotes Cell Motility By Modulating Cell Deformability And Contractility Via The Camp-Rhoa-Rock Axis In Human Breast Cancer Cells, Mijung Oh, Skylar Batty, Nayan Banerjee, Tae-Hyung Kim

Pathology Research and Scholarship

The mechanical properties, or mechanotypes, of cells are largely determined by their deformability and contractility. The ability of cancer cells to deform and generate contractile force is critical in multiple steps of metastasis. Identifying soluble cues that regulate cancer cell mechanotypes and understanding the underlying molecular mechanisms regulating these cellular mechanotypes could provide novel therapeutic targets to prevent metastasis. Although a strong correlation between high glucose level and cancer metastasis has been demonstrated, the causality has not been elucidated, and the underlying molecular mechanisms remain largely unknown. In this study, using novel high-throughput mechanotyping assays, we show that human breast …

Faculty, Staff and Students Publications

Military sexual trauma (MST) has deleterious long-term psychological consequences. Among female U.S. military members, MST is associated with increased risk for future interpersonal victimization, such as experiencing intimate partner violence (IPV). Few studies have investigated the implications of the cumulative effects of IPV and MST on psychological functioning. This study examined rates of co-exposure to MST, IPV, and their cumulative impact on psychological symptoms. Data were collected from 308 female Veterans (FVets; age:

Accuracy Of Artificial Intelligence In Estimating Best-Corrected Visual Acuity From Fundus Photographs In Eyes With Diabetic Macular Edema, William Paul, Philippe Burlina, Rohita Mocharla, Neil Joshi, Zhuolin Li, Sophie Gu, Onnisa Nanegrungsunk, Kira Lin, Susan B Bressler, Cindy X Cai, Jun Kong, T Y Alvin Liu, Hadi Moini, Weiming Du, Fouad Amer, Karen Chu, Robert Vitti, Farshid Sepehrband, Neil M Bressler

IMPORTANCE: Best-corrected visual acuity (BCVA) is a measure used to manage diabetic macular edema (DME), sometimes suggesting development of DME or consideration of initiating, repeating, withholding, or resuming treatment with anti-vascular endothelial growth factor. Using artificial intelligence (AI) to estimate BCVA from fundus images could help clinicians manage DME by reducing the personnel needed for refraction, the time presently required for assessing BCVA, or even the number of office visits if imaged remotely.

OBJECTIVE: To evaluate the potential application of AI techniques for estimating BCVA from fundus photographs with and without ancillary information.

DESIGN, SETTING, AND PARTICIPANTS: Deidentified color fundus …

BACKGROUND: A safe, effective, and reversible nonhormonal male contraceptive drug is greatly needed for male contraception as well as for circumventing the side effects of female hormonal contraceptives. Phosducin-like 2 (PDCL2) is a testis-specific phosphoprotein in mice and humans. We recently found that male PDCL2 knockout mice are sterile due to globozoospermia caused by impaired sperm head formation, indicating that PDCL2 is a potential target for male contraception. Herein, our study for the first time developed a biophysical assay for PDCL2 allowing us to screen a series of small molecules, to study structure-activity relationships, and to discover two PDCL2 binders …

Achieving Equity In Emergency Medicine Quality Measures Requires A Sex And Gender Lens, Ynhi T Thomas, Angela F Jarman, Nina G Faynshtayn, Greg B Buehler, Sara Andrabi, Alyson J Mcgregor

Faculty, Staff and Students Publications

BACKGROUND: Quality measures within Emergency Medicine (EM) were developed to standardize and improve care. Their development has been limited by lack of consideration of sex- and gender-based differences. Research has suggested that sex and gender can impact clinical care and treatment. Inclusion of sex and gender differences is needed to create EM quality measures that are equitable to all.

OBJECTIVE: The aim of the review is to provide a brief history of EM quality measures and the value of considering sex- and gender-based evidence in their development to ensure equity, using acute myocardial infarction (AMI) as an example.

Sex-Based Differences In The Presentation And Outcomes Of Acute Pulmonary Embolism: A Systematic Review And Meta-Analysis, Yu Zhang, Yu Qiu, Jinming Luo, Jian Zhang, Qingqing Yan

The Texas Heart Institute Journal

BACKGROUND: The study aimed to review differences in the presentation and outcomes of acute pulmonary embolism (PE) between men and women.

METHODS: PubMed, CENTRAL, Web of Science, and Embase were searched for studies comparing clinical features or outcomes of PE between men and women. Baseline comorbidities, risk factors, clinical features, and mortality rates were also compared between men and women.

RESULTS: Fourteen studies were included. It was noted that men presented with PE at a statistically significantly younger age than women (P < .001). Smoking history (P < .001), lung disease (P = .004), malignancy (P = .02), and unprovoked PE (P = .004) were significantly more frequent among men than among women. There was no difference between the sexes for hypertension, diabetes, and a history of recent immobilization. A significantly higher proportion of men presented with chest pain (P = .02) and hemoptysis (P < .001), whereas syncope (P = .005) was more frequent in women. Compared with men, women had a higher proportion of high-risk PE (P = .003). There was no difference in the use of thrombolytic therapy or inferior vena cava filter. Neither crude nor adjusted mortality rates were significantly different between men and women.

CONCLUSION: This review found that the age at presentation, comorbidities, and symptoms of PE differed between men and …

NF1 is a key tumor suppressor that represses both RAS and estrogen receptor-α (ER) signaling in breast cancer. Blocking both pathways by fulvestrant (F), a selective ER degrader, together with binimetinib (B), a MEK inhibitor, promotes tumor regression in NF1-depleted ER+ models. We aimed to establish approaches to determine how NF1 protein levels impact B+F treatment response to improve our ability to identify B+F sensitive tumors. We examined a panel of ER+ patient-derived xenograft (PDX) models by DNA and mRNA sequencing and found that more than half of these models carried an NF1 shallow deletion and generally have low mRNA …
