A Novel Grk3-Hdac2 Regulatory Pathway Is A Key Direct Link Between Neuroendocrine Differentiation And Angiogenesis In Prostate Cancer Progression, 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 …

Risks Factors And Outcomes For Isolated Catheter-Related Deep Venous Thrombosis In Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplantation, Ryan Basom, Stephanie J Lee, David Garcia, Cristhiam M Rojas Hernandez, Ang Li, Kylee L Martens

Faculty, Staff and Students Publications

INTRODUCTION: Patients undergoing allogenic hematopoietic stem cell transplantation (allo-HSCT) require indwelling central venous catheters. The comparative incidence, risk, and outcome of isolated catheter-related deep venous thrombosis (CR-DVT) versus pulmonary embolism/lower-extremity DVT (PE/LE-DVT) remains unclear.

MATERIALS AND METHODS: We conducted a retrospective cohort study for patients undergoing allo-HSCT from 2006 to 2019. CR-DVT and PE/LE-DVT outcomes were screened using ICD codes and radiology reports and confirmed by medical record reviews. Cox regression models were used to assess the association between thrombotic outcomes and pertinent baseline and time-varying covariates. The impact of thrombotic events within 1-year post-transplant (time-varying) on overall mortality was …

Maternal Metabolism Influences Neural Tube Closure

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, 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 …

In most eukaryotic cells, fatty acid synthesis (FAS) occurs in the cytoplasm and in mitochondria. However, the relative contribution of mitochondrial FAS (mtFAS) to the cellular lipidome is not well defined. Here we show that loss of function of Drosophila mitochondrial enoyl coenzyme A reductase (Mecr), which is the enzyme required for the last step of mtFAS, causes lethality, while neuronal loss of Mecr leads to progressive neurodegeneration. We observe a defect in Fe-S cluster biogenesis and increased iron levels in flies lacking mecr, leading to elevated ceramide levels. Reducing the levels of either iron or ceramide suppresses the neurodegenerative …

Early Initiation Of B-Vitamin Supplementation May Reduce Symptoms And Explain Intrafamilial Variability: Insights From Two Sibling Pairs From The Tango2 Natural History Study, Samuel J Mackenzie, Mahshid S Azamian, Daryl A Scott, Andres Hernandez-Garcia, Seema R Lalani

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 …

Faculty, Staff and Students Publications

Background & aims: Twenty-eight-day mortality ranges from 30-90% in patients with acute-on-chronic liver failure grades 2/3 (severe ACLF). Though liver transplantation (LT) has demonstrated a survival benefit, the scarcity of donor organs and uncertainty regarding post-LT mortality among patients with severe ACLF may cause hesitancy. We developed and externally validated a model to predict 1-year post-LT mortality in severe ACLF, called the Sundaram ACLF-LT-Mortality (SALT-M) score, and estimated the median length of stay (LoS) after LT (ACLF-LT-LoS).

Methods: In 15 LT centers in the US, we retrospectively identified a cohort of patients with severe ACLF transplanted between 2014-2019, followed up …
