Small extracellular vesicles (sEVs), otherwise known as exosomes, are nanoscale vesicles that cells release to communicate and affect their local and remote microenvironments. Cancer cells specifically use their sEVs to enable tumor survival, including inactivation of anti-tumor macrophage immune responses. For sEV studies in vitro, 2D cells grown in adherent culture are typically used to manufacture sEVs. To more closely simulate in vivo tissues, human hepatocellular carcinoma cells (HCCs) can be grown in a 3D ECM as spheroids. However, the ECM-based method is technically challenging as well as time-consuming since it is incredibly difficult to grow individual spheroids for the ...

Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody
All Graduate Plan B and other Reports
Avian species are highly susceptible to the hepatotoxic mycotoxin aflatoxin B1 (AFB1). Domesticated turkeys are exquisitely sensitive, due to a combination of highly-efficient hepatic cytochrome P450 (CYP)-mediated bioactivation, and to dysfunctional alpha-class glutathione S-transferases (GSTAs) which typically detoxify the bioactivated electrophilic metabolite exo-AFB1-8,9-epoxide (AFBO). Wild turkeys are relatively resistant to AFB1 in large part due to expression of functional GSTAs. Quail, a related Galliforme, are slightly less sensitive in vivo to AFB1, but whether this is related to the hepatic metabolic profiles of these two critical enzymes has not been rigorously evaluated ...

Prostate cancer occurs frequently in men and can often lead to death. Many cancers, including prostate cancer, can be initiated by oxidative insult caused by free radicals and reactive oxygen species. The superoxide dismutase family removes the oxygen-derived reactive oxygen species, and increased superoxide dismutase activity can often be protective against prostate cancer. Prostate cancer can be treated in a variety of ways, including surgery, androgen deprivation therapy, radiation therapy, and chemotherapy. The clinical trajectory of prostate cancer varies from patient to patient, but more aggressive tumors often tend to be radioresistant. This is often due to the free-radical and ...

Lung cancer remains the leading cause of cancer death worldwide and non-small cell lung carcinoma (NSCLC) represents 85% of newly diagnosed lung cancers. In this study, we utilized our untargeted assignment tool Small Molecule Isotope Resolved Formula Enumerator (SMIRFE) and ultra-high-resolution Fourier transform mass spectrometry to examine lipid profile differences between paired cancerous and non-cancerous lung tissue samples from 86 patients with suspected stage I or IIA primary NSCLC. Correlation and co-occurrence analysis revealed significant lipid profile differences between cancer and non-cancer samples. Further analysis of machine-learned lipid categories for the differentially abundant molecular formulas identified a high abundance sterol ...

Mental Health Or Cardiac Health. Is There A Reason To Choose? Cardiac Arrhythmias Induced By Atomoxetine And Methylphenidate, Gabriel Cismaru, Viorel Lupu
Journal of Mind and Medical Sciences
The current treatment of Attention Deficit Disorder and Attention Deficit with Hyperactivity consists mainly in the administration of Straterra (Atomoxetine) Concerta and Ritalin (Methylphenidate). The FDA warned that the products might increase systolic, diastolic blood pressure, and lead to ventricular arrhythmias. Arrhythmic events and sudden cardiac death were described in adults with preexistent heart disease. However, studies on children have failed to demonstrate a clear association between the arrhythmic events and these drugs, as demonstrated in adults. What should the attitude of the pediatric psychiatrist be towards the administration of these products? What examination should be made by the psychiatrist ...

Targeting the epidermal growth factor receptor (EGFR) with tyrosine kinase inhibitors (TKIs) is one of the major precision medicine treatment options for lung adenocarcinoma. Due to common development of drug resistance to first- and second-generation TKIs, third-generation inhibitors, including osimertinib and rociletinib, have been developed. A model of EGFR-driven lung cancer and a method to develop tumors of distinct epigenetic states through 3D organotypic cultures are described here. It is discovered that activation of the EGFR T790M/L858R mutation in lung epithelial cells can drive lung cancers with alveolar or bronchiolar features, which can originate from alveolar type 2 (AT2 ...

Breast cancer development is associated with macrophage infiltration and differentiation in the tumor microenvironment. Our previous study highlights the crucial function of reactive oxygen species (ROS) in enhancing macrophage infiltration during the disruption of mammary tissue polarity. However, the regulation of ROS and ROS-associated macrophage infiltration in breast cancer has not been fully determined. Previous studies identified retinoid orphan nuclear receptor alpha (RORα) as a potential tumor suppressor in human breast cancer. In the present study, we showed that retinoid orphan nuclear receptor alpha (RORα) significantly decreased ROS levels and inhibited ROS-mediated cytokine expression in breast cancer cells. RORα expression ...

In comparison to the general patient population, trauma patients show higher level detections of bloodborne infectious diseases, such as Hepatitis and Human Immunodeficiency Virus. In comparison to bloodborne pathogens, the prevalence of respiratory infections such as SARS-CoV-2 and how that relates with other variables, such as drug usage and trauma type, is currently unknown in trauma populations. Here, we evaluated SARS-CoV-2 seropositivity and antibody isotype profile in 2,542 trauma patients from six Level-1 trauma centers between April and October of 2020 during the first wave of the COVID-19 pandemic. We found that the seroprevalence in trauma victims 18-44 years ...

Because there is no effective treatment for late-stage prostate cancer (PCa) at this moment, identifying novel targets for therapy of advanced PCa is urgently needed. A new network-based systems biology approach, XDeath, is developed to detect crosstalk of signaling pathways associated with PCa progression. This unique integrated network merges gene causal regulation networks and protein-protein interactions to identify novel co-targets for PCa treatment. The results show that polo-like kinase 1 (Plk1) and DNA methyltransferase 3A (DNMT3a)-related signaling pathways are robustly enhanced during PCa progression and together they regulate autophagy as a common death mode. Mechanistically, it is shown that ...

Patients with advanced-stage gastroenteropancreatic neuroendocrine tumors (GEP-NETs) have a poor overall prognosis despite chemotherapy and radiotherapy (e.g., peptide receptor radionuclide therapy (PRRT)). Better treatment options are needed to improve disease regression and patient survival. The purpose of this study was to examine a new treatment strategy by combining PI3K/mTOR dual inhibition and radiotherapy. First, we assessed the efficacy of two PI3K/mTOR dual inhibitors, PF-04691502 and PKI-402, to inhibit pAkt and increase apoptosis in NET cell lines (BON and QGP-1) and patient-derived tumor spheroids as single agents or combined with radiotherapy (XRT). Treatment with PF-04691502 decreased pAkt (Ser473 ...

A Case Of Cocaine Toxicity From Body Stuffing, Justin Smith, James Lee, Alan Lucerna, James Espinosa
Stratford Campus Research Day
Body stuffing refers to the ingestion of an illegal substance in an effort to conceal it and avoid prosecution. This is distinct from, and more common than, the practice of body packing in which large amounts of an illegal substance are carefully packaged and ingested to be transported discreetly by smugglers [1]. While body packers tend to ingest much larger quantities of a drug, they are less prone to developing symptoms of drug toxicity due to the meticulous packaging methods used when compared with those who ingest packets of drugs in haste to avoid prosecution [2]. Many substances have been ...

Uvb-Induced Microvesicle Particle Release In Human Skin In Vivo Is Diminished Following Oral Vitamin C And E Antioxidant Administration, Benjamin Schmeusser, Cameron Mcglone, Jeffrey B. Travers
Medical Student Research Symposium Abstracts and Posters
An important question in photobiology asks how Ultraviolet B (UVB, 290 – 320 nm) radiation, which mostly absorbs in the outer epidermis of skin, can generate a systemic response such as immunosuppression. Previous in vitro and ex vivo studies demonstrate UVB-dependent release of bioactive molecule-containing microvesicle particles (MVPs) from keratinocytes. Furthermore, MVP release is diminished upon antioxidant administration. The purpose of this study is to examine UVB-induced MVP release and antioxidant response in vivo. In this IRB-approved study, 8 male participants with Fitzpatrick type I or II skin were treated with 1000 J/m2 UVB irradiation to a 5 by 5 ...
