Pituitary adenomas (PA) represent the largest group of intracranial neoplasms, yet the molecular mechanisms driving this disease remain largely unknown. The aim of this study was to use high-throughput screening to identify molecular pathways that may be playing a significant and consistent role in PA. RNA profiling using microarrays on eight local PAs identified the aryl hydrocarbon receptor (AHR) signalling pathway as a key canonical pathway down-regulated in all PA types. This was confirmed by qPCR in 31 tumours...

BACKGROUND: Peripheral arterial disease poses a significant burden in the hemodialysis (HD)-dependent population. Race is a known modifier of outcomes after surgical treatment of peripheral arterial disease. A comprehensive evaluation of the effect of race on infrainguinal bypass surgery (IBS) outcomes in HD patients is lacking. In this study, we evaluated the effects of race on long-term IBS outcomes in a large, nationally representative cohort of HD patients. METHODS: We studied all HD patients who underwent IBS between January 2007 and December 2011 in the United States Renal Disease System-Medicare matched database...

BACKGROUND AND AIMS: Myeloperoxidase (MPO), a product of systemic inflammation, promotes oxidation of lipoproteins; whereas, high-density lipoprotein (HDL) exerts anti-oxidative effects in part via paraoxonase-1 (PON1). MPO induces dysfunctional HDL particles; however, the interaction of circulating levels of these measures in cardiovascular disease (CVD) has not been studied in humans. We tested whether serum levels of MPO indexed to HDL particle concentration (MPO/HDLp) are associated with increased CVD risk in a large multiethnic population sample, free of CVD at baseline...

BACKGROUND: The outcomes of upper tract urothelial carcinoma (UTUC) receiving radical nephroureterectomy were usually limited to small sample size, case-control studies, and often focused on cancer progression. Risk of acute myocardial infarction (AMI) in these patients was never investigated. RESULTS: The overall incidences of AMI were 3.39, 1.44, and 1.70 per 10,000 person-years in the radical nephroureterectomy, nonnephroureterectomy, and non-UTUC cohorts, respectively...

OBJECTIVE: Several factors influence the clinical course of autoimmune inflammatory diseases such as MS and inflammatory bowel disease. Only recently, the complex interaction between the gut microbiome, dietary factors, and metabolism has started to be appreciated with regard to its potential to modulate acute and chronic inflammation. One of the molecular sensors that mediates the effects of these environmental signals on the immune response is the aryl hydrocarbon receptor (AHR), a ligand-activated transcription factor with key functions in immune cells...

Not much is known about the biotransformation capability of zebrafish (Danio rerio) embryos. For understanding possible toxicity differences to adult fish, it might be crucial to understand the biotransformation of chemicals in zebrafish embryos i.e. as part of toxicokinetics. The biotransformation capabilities were analysed for two different stages of zebrafish embryos in conjunction with the internal concentrations of a xenobiotic. Zebrafish embryos of the late cleavage/early blastula period (2-26 hpf) and the early pharyngula period (26-50 hpf) were exposed for 24 h to the AhR binding compound benz[a]anthracene (BaA)...

Children tend to confuse reversible letters such as b and d when they start learning to read. According to some authors, mirror errors are a consequence of the mirror generalization (MG) process that allows one to recognize objects independently of their left-right orientation. Although MG is advantageous for the visual recognition of objects, it is detrimental for the visual recognition of reversible letters. Previous studies comparing novice and expert readers demonstrated that MG must be inhibited to discriminate reversible single letters...

Concerns about the cardiovascular safety of dipeptidyl peptidase-4 (DPP-4) inhibitors persist. This study sought to determine whether there is a differential risk of hospitalization for cardiovascular diseases (CVDs) between DPP-4 inhibitors and glimepiride.We conducted this retrospective cohort study by using the Korean National Health Insurance Service database from December 1, 2008, to December 31, 2013. The study subjects were new users of DPP-4 inhibitors or glimepiride for type 2 diabetes. Outcome was defined as hospitalization for CVDs, including angina pectoris, myocardial infarction, transient cerebral ischemic attack, heart failure, or cerebrovascular disease or any procedure involving coronary artery bypass grafting or percutaneous coronary intervention...

REVIEW
Robert Formosa, Josanne Vassallo
The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor best known for its ability to mediate the effects of environmental toxins such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD or dioxin), polycyclic aromatic hydrocarbons (PAHs), benzene, and polychlorinated biphenyls (PCBs) through the initiation of transcription of a number of metabolically active enzymes. Therefore, the AHR has been studied mostly in the context of xenobiotic signaling. However, several studies have shown that the AHR is constitutively active and plays an important role in general cell physiology, independently of its activity as a xenobiotic receptor and in the absence of exogenous ligands...

Depression is a known barrier for antiretroviral therapy (ART) adherence, but less is understood about its effects on ART initiation. We followed 1013 HIV-infected individuals participating in the Partners Demonstration Project, an open-label study of integrated pre-exposure prophylaxis (PrEP) and ART delivery for HIV serodiscordant couples in Kenya and Uganda. Associations between depression, measured annually with the Hopkins Symptoms Checklist-Depression (HSCL-D), and ART initiation were assessed with Cox proportional hazards regression...

Interleukin-22 (IL-22) plays an important role in host immunity and tissue homeostasis in infectious and inflammatory diseases. However, the function and regulation of IL-22 in viral infection remain largely unknown. Here, we report that viral infection triggered early IL-22 production from the liver and lymphoid organs. γδ T cells are the main immune cells to produce IL-22 in the liver, a process mediated by the IL-23/phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin complex 1 (mTORC1) signaling pathway...
