Comparative Transcriptomic Analysis Of Human Placentae At Term And Preterm Delivery., Alison G Paquette, Heather M Brockway, Nathan D Price, Louis J Muglia

Articles, Abstracts, and Reports

Preterm birth affects 1 out of every 10 infants in the United States, resulting in substantial neonatal morbidity and mortality. Currently, there are few predictive markers and few treatment options to prevent preterm birth. A healthy, functioning placenta is essential to positive pregnancy outcomes. Previous studies have suggested that placental pathology may play a role in preterm birth etiology. Therefore, we tested the hypothesis that preterm placentae may exhibit unique transcriptomic signatures compared to term samples reflective of their abnormal biology leading to this adverse outcome. We aggregated publicly available placental villous microarray data to generate a preterm and term …

Sivcpz Closely Related To The Ancestral Hiv-1 Is Less Or Non-Pathogenic To Humans In A Hu-Blt Mouse Model, Zhe Yuan, Guobin Kang, Lance Daharsh, Wenjin Fan, Qingsheng Li

Nebraska Center for Virology: Faculty Publications

The HIV-1 pandemic is a consequence of the cross-species transmission of simian immunodeficiency virus in wild chimpanzees (SIVcpz) to humans. Our previous study demonstrated SIVcpz strains that are closely related to the ancestral viruses of HIV-1 groups M (SIVcpzMB897) and N (SIVcpzEK505) and two SIVcpz lineages that are not associated with any known HIV-1 infections in humans (SIVcpzMT145 and SIVcpzBF1167), all can readily infect and robustly replicate in the humanized-BLT mouse model of humans. However, the comparative pathogenicity of different SIVcpz strains remains unknown. Herein, we compared the pathogenicity of the above four SIVcpz strains with HIV-1 using humanized-BLT mice. …

Zika virus (ZIKV), an emerging arbovirus, has become a major human health concern globally due to its association with congenital abnormalities and neurological diseases. Licensed vaccines or antivirals against ZIKV are currently unavailable. Here, by employing a structure-based approach targeting the ZIKV RNA-dependent RNA polymerase (RdRp), we conducted in silico screening of a library of 100,000 small molecules and tested the top ten lead compounds for their ability to inhibit the virus replication in cell-based in vitro assays. One compound, 3-chloro-N-[({4-[4-(2-thienylcarbonyl)-1-piperazinyl]phenyl}amino)carbonothioyl]-1-benzothiophene-2-carboxamide (TPB), potently inhibited ZIKV replication at submicromolar concentrations. Molecular docking analysis suggests that …

The Mechanism Of Tobacco-Induced Decrements In Mucociliary Clearance, Vivian Lin

All ETDs from UAB

Chronic obstructive pulmonary disease (COPD), characterized by progressive loss of lung function including mucus obstruction and airway remodeling, is primarily caused by cigarette smoking. This pulmonary phenotype resembles that of cystic fibrosis (CF), which results from genetic mutations in the cystic fibrosis transmembrane conductance regulator (CFTR), an ion channel important in maintaining airway surface hydration and mucus clearance. Cigarette smoke exposure has been found to induce acquired CFTR dysfunction, leading to airway dehydration, abnormal mucin production, and impaired mucus transport. Smoke exposure also induces mucus hypersecretion and ciliary dysfunction; together, these changes result in defective mucus clearance and subsequent muco-obstruction. …

The Effects Of Ketamine And Other Rapid Antidepressants On Hippocampal Circuits, Allie J. Widman

All ETDs from UAB

Major Depressive Disorder (MDD) in a common mental disorder that can impair cognitive functioning and negatively impact hippocampus. While several pharmacological treatments are currently available for MDD, most target the monoamine system, providing little variety in approaching treatment. Additionally, a large percentage of people with MDD have an inadequate response to this drug class, leaving them with little optimism of a full functional recovery. Recently, low-dose ketamine, an open-channel N-methyl D-aspartate receptor (NMDAR) antagonist, produced rapid antidepressant effects in humans, including people who do not respond to monoamine-based therapies, that lasted for days. The antidepressant-like behavioral effect of ketamine is …

Elucidating The Role Of Hedgehog Signaling In Modulating Macrophage Function In Breast Cancer, Ann Hanna

All ETDs from UAB

In the tumor microenvironment, breast cancer cells participate in crosstalk with the surrounding stroma. This tumoral-stromal interaction forms a balance that dictates tumor suppressing or tumor promoting response mechanisms. Macrophages in the tumor microenvironment are plastic and can mediate several functions depending on their activation states. Tumor associated macrophages co-exist as two major phenotypes: anti-tumorigenic and immune-eliciting classically activated M1 as well as tumor-promoting and immune-suppressive alternatively activated M2 macrophages. Alternatively activated macrophages are specifically associated with more aggressive stages and poor clinical outcomes in breast cancer patients as they suppress the tumoricidal properties of the immune system, thus facilitating …

Nano-Pulse Stimulation Ablates Orthotopic Rat Hepatocellular Carcinoma And Induces Innate And Adaptive Memory Immune Mechanisms That Prevent Recurrence, Brittany P. Lassiter, Siqi Guo, Stephen J. Beebe

Bioelectrics Publications

Nano-pulse stimulation (NPS), previously called nsPEFs, induced a vaccine-like effect after ablation of orthotopic N1-S1 hepatocellular carcinoma (HCC), protecting rats from subsequent challenges with N1-S1 cells. To determine immunity, immune cell phenotypes were analyzed in naïve, treated and protected rats. NPS provides a positive, post-ablation immuno-therapeutic outcome by alleviating immunosuppressive T regulatory cells (Treg) in the tumor microenvironment (TME), allowing dendritic cell influx and inducing dynamic changes in natural killer cells (NKs), NKT-cells and T-lymphocytes in blood, spleen and liver. NPS induced specific increases in NKs and NKT-cells expressing CD8 and activation receptors CD314-NKG2D and CD161 (NK1.1) in the TME …

Research outputs 2014 to 2021

As child mortality rates overall are decreasing, non-communicable conditions, such as genetic disorders, constitute an increasing proportion of child mortality, morbidity and disability. To date, policy and public health programmes have focused on common genetic disorders. Rare single gene disorders are an important source of morbidity and premature mortality for affected families. When considered collectively, they account for an important public health burden, which is frequently under-recognised. To document the collective frequency and health burden of rare single gene disorders, it is necessary to aggregate them into large manageable groupings and take account of their family implications, effective interventions and …

Increased Risk For Obesity And Diabetes With Neurodegeneration In Developing Countries, I. J. Martins

Research outputs 2014 to 2021

The incidence of global obesity and Type 2 diabetes has increased and is predicted to rise to 30% of the global population. Diet and lifestyle factors are incapable to resolve the increased incidence for obesity and diabetes in various populations of the world. Developing countries have come to the forefront because of the higher diabetic epidemic. The urbanization may possibly provide an explanation for the global diabetic epidemic. In Western countries the metabolic syndrome and non alcoholic fatty liver disease (NAFLD) have reached 30 % of the population and now at present NAFLD afflicts 20% of developing populations. Western diets …
