Placental Genetic Variations In Vitamin D Metabolism And Birthweight., Tsegaselassie Workalemahu, Sylvia E Badon, Michal Dishi-Galitzky, Chunfang Qiu, Michelle A Williams, Tanya Sorensen, Daniel A Enquobahrie

Articles, Abstracts, and Reports

INTRODUCTION: Vitamin D has pleiotropic functions that regulate fetal growth and development. We investigated associations of common placental genetic variations in vitamin D metabolism with birthweight.

METHODS: The study was conducted among participants (506 maternal-infant pairs) of a pregnancy cohort study. Data were collected using interviewer-administered questionnaires and post-delivery medical record abstraction. DNA, extracted from placental samples collected at delivery, was genotyped for eight single nucleotide polymorphisms (SNPs) in five vitamin D metabolism genes (CUBN, LRP2, VDR, GC, and CYP2R1). Linear and logistic regression models were used to evaluate associations of SNPs with birthweight and risk of low birthweight, respectively. …

Foxc1 Is Associated With Estrogen Receptor Alpha And Affects Sensitivity Of Tamoxifen Treatment In Breast Cancer., Jinhua Wang, Yali Xu, Li Li, Lin Wang, Ru Yao, Qiang Sun, Guanhua Du

Articles, Abstracts, and Reports

FOXC1 is a member of Forkhead box transcription factors that participates in embryonic development and tumorigenesis. Our previous study demonstrated that FOXC1 was highly expressed in triple-negative breast cancer. However, it remains unclear what is the relation between FOXC1 and ERα and if FOXC1 regulates expression of ERα. To explore relation between FOXC1 and ERα and discover regulation of ERα expression by FOXC1 in breast cancer, we analyzed data assembled in the Oncomine and TCGA, and found that there was significantly higher FOXC1 expression in estrogen receptor-negative breast cancer than that in estrogen receptor-positive breast cancer. Overexpression of FOXC1 reduced …


New Developments In The Treatment Of Primary Biliary Cholangitis - Role Of Obeticholic Acid., Manan A Jhaveri, Kris V Kowdley Jan 2017

New Developments In The Treatment Of Primary Biliary Cholangitis - Role Of Obeticholic Acid., Manan A Jhaveri, Kris V Kowdley

Articles, Abstracts, and Reports

Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic liver disease that predominantly affects women in early to middle age. It is typically associated with autoantibodies to mitochondrial antigens and results in immune-mediated destruction of small and medium-sized intrahepatic bile ducts leading to cholestasis, hepatic fibrosis and may progress to cirrhosis or hepatic failure and, in some cases, hepatocellular carcinoma. The clinical presentation and the natural history of PBC have improved over the years due to recognition of earlier widespread use of ursodeoxycholic acid (UDCA); about one-third of patients show suboptimal biochemical response to UDCA with poor prognosis. Until recently, …

Articles, Abstracts, and Reports

Human papilloma virus positive (HPV+) tumors represent a large proportion of anal, vulvar, vaginal, cervical and head and neck squamous carcinomas (HNSCC) and late stage invasive disease is thought to originate from a premalignant state. Cyclic dinucleotides that activate STimulator of INterferon Genes (STING) have been shown to cause rapid regression of a range of advanced tumors. We aimed to investigate STING ligands as a novel treatment for papilloma. We tested therapies in a spontaneous mouse model of papilloma of the face and anogenital region that histologically resembles human HPV-associated papilloma. We demonstrate that STING ligands cause rapid regression of …


Catastrophes And Complicated Intraoperative Events During Robotic Lung Resection., Brian E Louie Jan 2017

Catastrophes And Complicated Intraoperative Events During Robotic Lung Resection., Brian E Louie

Articles, Abstracts, and Reports

Intraoperative complications and catastrophes are an accepted and perhaps inevitable aspect of all surgeries. Anatomic pulmonary resection puts in close proximity the tracheal-bronchial tree, pulmonary vasculature, heart and great vessels within the small volume area of the chest. Fortunately, major complications and catastrophes are uncommon regardless of surgical approach. Pulmonary arterial injury is the most frequently reported. Most injuries necessitate a thoracotomy for definitive management though novel techniques are emerging for minimally invasive management. This section focuses on intraoperative pulmonary artery and vein injuries, major airway injuries and transections, injuries to major abdominal organs and effects of carbon dioxide insufflation …

He was subsequently started on rivaroxaban therapy for a combined treatment period of 12 months, during and after which he persisted to have evidence of a DVT. The patient's prescribed drug regimen was changed from rivaroxaban to warfarin, which demonstrated a rapid resolution of the DVTs as determined by ultrasound assessment of our patient's lower extremity veins. Rivaroxaban, a factor Xa inhibitor, is a well-known oral anticoagulant that is used for …


Early Mutation Bursts In Colorectal Tumors., Junsong Zhao, Matthew P Salomon, Darryl Shibata, Christina Curtis, Kimberly Siegmund, Paul Marjoram Jan 2017

Early Mutation Bursts In Colorectal Tumors., Junsong Zhao, Matthew P Salomon, Darryl Shibata, Christina Curtis, Kimberly Siegmund, Paul Marjoram

Articles, Abstracts, and Reports

Tumor growth is an evolutionary process involving accumulation of mutations, copy number alterations, and cancer stem cell (CSC) division and differentiation. As direct observation of this process is impossible, inference regarding when mutations occur and how stem cells divide is difficult. However, this ancestral information is encoded within the tumor itself, in the form of intratumoral heterogeneity of the tumor cell genomes. Here we present a framework that allows simulation of these processes and estimation of mutation rates at the various stages of tumor development and CSC division patterns for single-gland sequencing data from colorectal tumors. We parameterize the mutation …

Differential Phenotypes Of Memory Cd4 And Cd8 T Cells In The Spleen And Peripheral Tissues Following Immunostimulatory Therapy., Gail D Sckisel, Annie Mirsoian, Christine M Minnar, Marka R Crittenden, Brendan Curti, Jane Q Chen, Bruce R Blazar, Alexander D Borowsky, Arta M Monjazeb, William J Murphy

Articles, Abstracts, and Reports

BACKGROUND: Studies assessing immune parameters typically utilize human PBMCs or murine splenocytes to generate data that is interpreted as representative of immune status. Using splenocytes, we have shown memory CD4-T cells that expand following systemic immunostimulatory therapies undergo rapid IFNg-mediated activation induced cell death (AICD) resulting in a net loss of total CD4-T cells which correlates with elevated PD-1 expression. This is in contrast to CD8-T cells which expand with minimal PD-1 upregulation and apoptosis. In this study we expand upon our previous work by evaluating CD4 and CD8-T cell phenotype and distribution in peripheral organs which are more representative …

Articles, Abstracts, and Reports

Formation of metastases, also known as cancer dissemination, is an important stage of breast cancer (BrCa) development. KISS1 expression is associated with inhibition of metastases development. Recently we have demonstrated that BrCa metastases to the brain exhibit low levels of KISS1 expression at both mRNA and protein levels. By using multicolor immunofluorescence and coculture techniques here we show that normal adult astrocytes in the brain are capable of promoting metastatic transformation of circulating breast cancer cells localized to the brain through secretion of chemokine CXCL12. The latter was found in this study to downregulate KISS1 expression at the post-transcriptional level …

Articles, Abstracts, and Reports

Measuring cardiac troponins is integral to diagnosing acute myocardial infarction (AMI); however, troponins may be elevated without AMI, and the use of multiple different assays confounds comparisons. We considered characteristics and serial troponin values in emergency department chest pain patients with and without AMI to interpret troponin excursions. We compared serial troponin in 124 AMI and non-AMI patients from the observational Performance of Triage Cardiac Markers in the Clinical Setting (PEARL) study who presented with chest pain and had at least one troponin value exceeding the 99th percentile of normal. Because 8 assays were used during data collection, we employed …

Articles, Abstracts, and Reports

Huntington's disease (HD) is an autosomal dominant neurodegenerative disease whose predominant neuropathological signature is the selective loss of medium spiny neurons in the striatum. Despite this selective neuropathology, the mutant protein (huntingtin) is found in virtually every cell so far studied, and, consequently, phenotypes are observed in a wide range of organ systems both inside and outside the central nervous system. We, and others, have suggested that peripheral dysfunction could contribute to the rate of progression of striatal phenotypes of HD. To test this hypothesis, we lowered levels of huntingtin by treating mice with antisense oligonucleotides (ASOs) targeting the murine …
