Global Sumoylation In Mouse Oocytes Maintains Oocyte Identity And Regulates Chromatin Remodeling And Transcriptional Silencing At The End Of Folliculogenesis, Shawn M Briley, Avery A Ahmed, Tessa E Steenwinkel, Peixin Jiang, Sean M Hartig, Karen Schindler, Stephanie A Pangas

Faculty, Staff and Students Publications

Meiotically competent oocytes in mammals undergo cyclic development during folliculogenesis. Oocytes within ovarian follicles are transcriptionally active, producing and storing transcripts required for oocyte growth, somatic cell communication and early embryogenesis. Transcription ceases as oocytes transition from growth to maturation and does not resume until zygotic genome activation. Although SUMOylation, a post-translational modification, plays multifaceted roles in transcriptional regulation, its involvement during oocyte development remains poorly understood. In this study, we generated an oocyte-specific knockout of Ube2i, encoding the SUMO E2 enzyme UBE2I, using Zp3-cre+ to determine how loss of oocyte SUMOylation during folliculogenesis affects oocyte development. Ube2i Zp3-cre+ female …

Elevated triglycerides and non-high-density lipoprotein cholesterol (HDL-C) are risk factors for atherosclerotic cardiovascular disease (ASCVD). ARO-ANG3 is an RNA interference therapy that targets angiopoietin-like protein 3 (ANGPTL3), a regulator of lipoprotein metabolism. This first-in-human, phase 1, randomized, placebo-controlled, open-label trial investigated single and repeat ARO-ANG3 doses in four cohorts of fifty-two healthy participants and one cohort of nine participants with hepatic steatosis, part of a basket trial. Safety (primary objective) and pharmacokinetics (in healthy participants) and pharmacodynamics (secondary objectives) of ARO-ANG3 were evaluated. ARO-ANG3 was generally well tolerated, with similar frequencies of treatment-emergent adverse events in active and placebo groups. …

Refining Contract Management: Essays On Relational Contracting, Transaction Costs, And Text Analysis, Timothy E. Landucci

Theses and Dissertations

This dissertation refines defense contracting by addressing aspects of managing contractual relationships. While the setting and data relate to defense contracts, the lessons can be expanded to nonprofit contracting beyond defense and even to contract management in general. First it presents a game theoretic model of a relational contract between a for-profit supplier and a non-profit buyer and explores how the model could be used to promote stability, manage costs, enhance cooperation, and encourage long-term capacity. The dissertation then explores governance alignment using transaction cost economics (TCE) and Department of the Air Force contracting data. One analysis uses data from …

The Transcription Factor Chrebp Links Mitochondrial Lipidomes To Mitochondrial Morphology And Progression Of Diabetic Kidney Disease, Li Li, Jianyin Long, Koki Mise, Naravat Poungavrin, Philip L Lorenzi, Iqbal Mahmud, Lin Tan, Pradip K Saha, Yashpal S Kanwar, Benny H Chang, Farhad R Danesh

Faculty, Staff and Students Publications

A substantial body of evidence has established the contributions of both mitochondrial dynamics and lipid metabolism to the pathogenesis of diabetic kidney disease (DKD). However, the precise interplay between these two key metabolic regulators of DKD is not fully understood. Here, we uncover a link between mitochondrial dynamics and lipid metabolism by investigating the role of carbohydrate-response element-binding protein (ChREBP), a glucose-responsive transcription factor and a master regulator of lipogenesis, in kidney podocytes. We find that inducible podocyte-specific knockdown of ChREBP in diabetic db/db mice improves key biochemical and histological features of DKD in addition to significantly reducing mitochondrial fragmentation. …

A Novel Grk3-Hdac2 Regulatory Pathway Is A Key Direct Link Between Neuroendocrine Differentiation And Angiogenesis In Prostate Cancer Progression, Samira Naderinezhad, Guoliang Zhang, Zheng Wang, Dayong Zheng, Mohit Hulsurkar, Michael Bakhoum, Ning Su, Han Yang, Tao Shen, Wenliang Li

Faculty, Staff and Students Publications

The mechanisms underlying the progression of prostate cancer (PCa) to neuroendocrine prostate cancer (NEPC), an aggressive PCa variant, are largely unclear. Two prominent NEPC phenotypes are elevated NE marker expression and heightened angiogenesis. Identifying the still elusive direct molecular links connecting angiogenesis and neuroendocrine differentiation (NED) is crucial for our understanding and targeting of NEPC. Here we found that histone deacetylase 2 (HDAC2), whose role in NEPC has not been reported, is one of the most upregulated epigenetic regulators in NEPC. HDAC2 promotes both NED and angiogenesis. G protein-coupled receptor kinase 3 (GRK3), also upregulated in NEPC, is a critical …

Faculty, Staff and Students Publications

TANGO2-deficiency disorder (TDD) is an autosomal recessive condition arising from pathogenic biallelic variants in the TANGO2 gene. TDD is characterized by symptoms typically beginning in late infancy including delayed developmental milestones, cognitive impairment, dysarthria, expressive language deficits, and gait abnormalities. There is wide phenotypic variability where some are severely affected while others have mild symptoms. This variability has been documented even among sibling pairs who share the same genotype, but reasons for this variability have not been well understood. Emerging data suggest a potential link between B-complex or multivitamin supplementation and decreased metabolic crises in TDD. In this report, we …

Several molecular and phenotypic algorithms exist that establish genotype-phenotype correlations, including facial recognition tools. However, no unified framework that investigates both facial data and other phenotypic data directly from individuals exists. We developed PhenoScore: an open-source, artificial intelligence-based phenomics framework, combining facial recognition technology with Human Phenotype Ontology data analysis to quantify phenotypic similarity. Here we show PhenoScore's ability to recognize distinct phenotypic entities by establishing recognizable phenotypes for 37 of 40 investigated syndromes against clinical features observed in individuals with other neurodevelopmental disorders and show it is an improvement on existing approaches. PhenoScore provides predictions for individuals with variants …

Unbiased informatics approaches have the potential to generate insights into uncharacterized signaling pathways in human disease. In this study, we generated longitudinal transcriptomic profiles of plaque psoriasis lesions from patients enrolled in a clinical trial of the anti-IL17A antibody ixekizumab (IXE). This dataset was then computed against a curated matrix of over 700 million data points derived from published psoriasis and signaling node perturbation transcriptomic and chromatin immunoprecipitation-sequencing datasets. We observed substantive enrichment within both psoriasis-induced and IXE-repressed gene sets of transcriptional targets of members of the MuvB complex, a master regulator of the mitotic cell cycle. These gene sets …

Maternal Metabolism Influences Neural Tube Closure, Rachel A Keuls, Richard H Finnell, Ronald J Parchem

Faculty, Staff and Students Publications

Changes in maternal nutrient availability due to diet or disease significantly increase the risk of neural tube defects (NTDs). Because the incidence of metabolic disease continues to rise, it is urgent that we better understand how altered maternal nutrient levels can influence embryonic neural tube development. Furthermore, primary neurulation occurs before placental function during a period of histiotrophic nutrient exchange. In this review we detail how maternal metabolites are transported by the yolk sac to the developing embryo. We discuss recent advances in understanding how altered maternal levels of essential nutrients disrupt development of the neuroepithelium, and identify points of …

Myths And Methodologies: Cardiopulmonary Exercise Testing For Surgical Risk Stratification In Patients With An Abdominal Aortic Aneurysm; Balancing Risk Over Benefit, Damian M Bailey, Richard G Davies, George A Rose, Michael H Lewis, Ahmed Abd Aldayem, Chistopher P Twine, Wael Awad, Matti Jubouri, Idhrees Mohammed, Carlos A Mestres, Edward P Chen, Joseph S Coselli, Ian M Williams, Mohamad Bashir, International Academic Surgical Consortium (Thalamus)

Faculty, Staff and Students Publications

The extent to which patients with an abdominal aortic aneurysm (AAA) should exercise remains unclear, given theoretical concerns over the perceived risk of blood pressure-induced rupture, which is often catastrophic. This is especially pertinent during cardiopulmonary exercise testing, when patients are required to perform incremental exercise to symptom-limited exhaustion for the determination of cardiorespiratory fitness. This multimodal metric is being used increasingly as a complementary diagnostic tool to inform risk stratification and subsequent management of patients undergoing AAA surgery. In this review, we bring together a multidisciplinary group of physiologists, exercise scientists, anaesthetists, radiologists and surgeons to challenge the enduring …

Tissue-resident macrophages (TRMs) are long-lived cells that maintain locally and can be phenotypically distinct from monocyte-derived macrophages. Whether TRMs and monocyte-derived macrophages have district roles under differing pathologies is not understood. Here, we showed that a substantial portion of the macrophages that accumulated during pancreatitis and pancreatic cancer in mice had expanded from TRMs. Pancreas TRMs had an extracellular matrix remodeling phenotype that was important for maintaining tissue homeostasis during inflammation. Loss of TRMs led to exacerbation of severe pancreatitis and death, due to impaired acinar cell survival and recovery. During pancreatitis, TRMs elicited protective effects by triggering the accumulation …
