Celecoxib use and circulating oxylipins in a colon polyp prevention trial.

Drugs that inhibit cyclooxygenase (COX)-2 and the metabolism of arachidonic acid (ARA) to prostaglandin E2 are potent anti-inflammatory agents used widely in the treatment of joint and muscle pain. Despite their benefits, daily use of these drugs has been associated with hypertension, cardiovascular and gastrointestinal toxicities. It is now recognized that ARA is metabolized to a number of bioactive oxygenated lipids (oxylipins) by cyclooxygenase (COX), lipoxygenase (LOX), and cytochrome P450 (CYP450) enzy...

Ethanol sensitizes hepatocytes for TGF-β-triggered apoptosis.

Alcohol abuse is a global health problem causing a substantial fraction of chronic liver diseases. Abundant TGF-β-a potent pro-fibrogenic cytokine-leads to disease progression. Our aim was to elucidate the crosstalk of TGF-β and alcohol on hepatocytes. Primary murine hepatocytes were challenged with ethanol and TGF-β and cell fate was determined. Fluidigm RNA analyses revealed transcriptional effects that regulate survival and apoptosis. Mechanistic insights were derived from enzyme/pathway inhibition ex...

Mucosal-Associated Invariant T Cells in Chronic Inflammatory Liver Disease.

The broadening field of microbiome research has led to a substantial reappraisal of the gut-liver axis and its role in chronic liver disease. The liver is a central immunologic organ that is continuously exposed to food and microbial-derived antigens from the gastrointestinal tract. Mucosal-associated invariant T (MAIT) cells are enriched in the human liver and can be activated by inflammatory cytokines and microbial antigens. In chronic inflammatory liver disease, MAIT cells are depleted suggesting an impa...

Development and Comparison of Two Immuno-disaggregation Based Bioassays for Cell Secretome Analysis.

Cell secretome analysis has gained increasing attention towards the development of effective strategies for disease treatment. Analysis of cell secretome enables the platform to monitor the status of disease progression, facilitating therapeutic outcomes. However, cell secretome analysis is very challenging due to its versatile and dynamic composition. Here, we report the development of two immuno-disaggregation bioassays using functionalized microparticles for the quantitative analysis of the cell secretom...

Testing therapeutics in cell-based assays: Factors that influence the apparent potency of drugs.

Identifying effective antivirals for treating Ebola virus disease (EVD) and minimizing transmission of such disease is critical. A variety of cell-based assays have been developed for evaluating compounds for activity against Ebola virus. However, very few reports discuss the variable assay conditions that can affect the results obtained from these drug screens. Here, we describe variable conditions tested during the development of our cell-based drug screen assays designed to identify compounds with anti-E...

Effect of high-dose ginsenoside complex (UG0712) supplementation on physical performance of healthy adults during a 12-week supervised exercise program: A randomized placebo-controlled clinical trial.

Ginseng has been used as an ergogenic agent, although evidence for its effectiveness is weak. A randomized, double-blind, placebo-controlled clinical trial was conducted to evaluate the effect of a ginsenoside complex (UG0712) on changes in exercise performance.

Blastomycosis-like Pyoderma Arising in Lichen Planus.

Blastomycosis-like pyoderma (BLP) is a rare reactive skin disease that is most commonly caused by bacterial infection. Herein we present a case of BLP arising in lichen planus, a chronic inflammatory disease. We propose Wolf's isotopic response, or the appearance of a new skin disease at the site of an existing and unrelated disease, as the underlying molecular mechanism responsible for this unusual physical presentation. It is important that clinicians recognize atypical morphologies such as BLP, which mim...

Generation of induced pluripotent stem cell line, CSSi002-A (2851), from a patient with juvenile Huntington Disease.

Huntington Disease (HD) is an autosomal dominant disorder characterized by motor, cognitive and behavioral features caused by a CAG expansion in the HTT gene beyond 35 repeats. The juvenile form (JHD) may begin before the age of 20years and is associated with expanded alleles as long as 60 or more CAG repeats. In this study, induced pluripotent stem cells were generated from skin fibroblasts of a 8-year-old child carrying a large size mutation of 84 CAG repeats in the HTT gene. HD appeared at age 3 with mix...

The established cell line was authenticated by assessing its DNA micro...

Human Herpesvirus-6B (HHV-6B) Reactivation is a Risk Factor for Grade 2-4 Acute Graft-Versus-Host Disease (aGVHD) after Hematopoietic Stem Cell Transplantation (HCT): a Systematic Review and Meta-Analysis.

Graft-versus-host disease (GVHD) is an important cause of morbidity and mortality following allogeneic hematopoietic cell transplantation (HCT). Many studies have suggested that HHV-6B plays a role in acute GVHD (aGVHD) following HCT. Our objective was to systematically summarize and analyze evidence regarding HHV-6B reactivation and development of aGVHD.

Efficacy and Safety of First-line Avelumab Treatment in Patients With Stage IV Metastatic Merkel Cell Carcinoma: A Preplanned Interim Analysis of a Clinical Trial.

Merkel cell carcinoma (MCC) is an aggressive skin cancer that is associated with poor survival outcomes in patients with distant metastatic disease. Results of part A of the JAVELIN Merkel 200 trial (avelumab in patients with Merkel cell carcinoma) showed that avelumab, an anti-programmed cell death ligand 1 (PD-L1) antibody, demonstrated efficacy in second-line or later treatment of patients with metastatic MCC (mMCC).

Transcriptional alterations in skin fibroblasts from Parkinson's disease patients with parkin mutations.

Mutations in the parkin gene (PRKN) are the most common cause of autosomal-recessive juvenile Parkinson's disease (PD). PRKN encodes an E3 ubiquitin ligase that is involved in multiple regulatory functions including proteasomal-mediated protein turnover, mitochondrial function, mitophagy, and cell survival. However, the precise molecular events mediated by PRKN mutations in PRKN-associated PD (PRKN-PD) remain unknown. To elucidate the cellular impact of parkin mutations, we performed an RNA sequencing study...

The phenomenology of cell size control.

Cells control their size through an intricate balance of cell growth, cell division, and cell death. Extensive work on unicellular model organisms revealed that cell-size-dependent cell cycle progression accounts for major aspects of cell size regulation and provided insights into the underlying molecular mechanisms. Nevertheless, elaborate live-cell imaging approaches still reveal new phenomenological observations that challenge our simplified models of size regulation and raise the question of what determ...

Human Pluripotent Stem Cell-Derived Endoderm for Modeling Development and Clinical Applications.

The liver, lung, pancreas, and digestive tract all originate from the endoderm germ layer, and these vital organs are subject to many life-threatening diseases affecting millions of patients. However, primary cells from endodermal organs are often difficult to grow in vitro. Human pluripotent stem cells thus hold great promise for generating endoderm cells and their derivatives as tools for the development of new therapeutics against a variety of global healthcare challenges. Here we describe recent advanc...

Deciphering Pancreatic Islet β Cell and α Cell Maturation Pathways and Characteristic Features at the Single-Cell Level.

Mesenchymal stem cell transplantation and aerobic exercise for Parkinson's disease: therapeutic assets beyond the motor domain.

Parkinson's disease (PD) is a very common neurodegenerative condition in which both motor and nonmotor deficits evolve throughout the course of the disease. Normally characterized as a movement disorder, PD has been broadly studied from a motor perspective. However, mild to moderate cognitive deficits began to appear in the early phases of the disease, even before motor disturbances actually manifest, and continue to progress relentlessly. These nonmotor manifestations are also a source of detriment to the ...

Beta catenin is regulated by its subcellular distribution and mutant huntingtin status in Huntington's disease cell STHdhQ111/HdhQ111.

Dysregulation of gene expression at RNA and protein level is a hallmark of Huntington's disease (HD). Altered levels of microRNAs and beta catenin in HD were studied earlier; however, any direct involvement of full length, basally-expressing mutant huntingtin (Htt) remained to be elusive. Here we reported that the gain-of-function mutation of full-length basally-expressing Htt in HD cell Q111 (STHdhQ111/HdhQ111) upregulated microRNA-214 and decreased beta catenin & its transcriptional activity in an aggrega...

Aberrant expression of LncRNA-MIR31HG regulates cell migration and proliferation by affecting miR-31 and miR-31* in Hirschsprung's disease.

Hirschsprung's disease (HSCR) is a birth defect that causes a failure of the enteric nervous system to cover the distal gut during early embryonic development. Evidence shows that long non-coding RNAs (lncRNA) play important roles in HSCR. The MIR31 host gene (MIR31HG), also known as Loc554202, is a long non-coding RNA (lncRNA), which acts as the host gene of (microRNA) miR-31 and miR-31*. There have been no studies regarding its function in early developmental defects during pregnancy, and its downstream g...

CircSNCA downregulation by pramipexole treatment mediates cell apoptosis and autophagy in Parkinson's disease by targeting miR-7.

We aimed to explore the mechanism of pramipexole (PPX) actions in the treatment of Parkinson's disease (PD). Genes related to PD and PPX were screened through bioinformatics retrieval. The PD model was constructed by applying 1-methyl-4-phenylpyridinium (MMP+). The RNA expression levels of circSNCA, , apoptosis-related genes (, , , and ) and miR-7 were detected by qRT-PCR. Protein expression was determined by western blot. The interactions between circSNCA-miR-7- were verified by dual luciferase assay and ...

Humeral metastasis of renal cancer: surgical options and a review of literature.

The humerus is the second most common long bone site of metastatic disease from renal cell carcinomas (RCC) after femur. Surgery has an important role in the treatment of these lesions due to renal cell tumor's resistance to chemotherapy and radiotherapy.

New models to study vascular mural cell embryonic origin: implications in vascular diseases.

A key question in vascular biology is how the diversity of origin of vascular mural cells, namely smooth muscle cells and pericytes influences vessel properties, in particular the regional propensity to vascular diseases. This review therefore first describes the role and regulation of mural cells during vascular formation, with a focus on embryonic origin. We then consider the evidence that connects heterogeneities in smooth muscle cell and pericyte origins with disease. Since this idea has major implicati...

Involvement of Alveolar Epithelial Cell Necroptosis in IPF Pathogenesis.

Alveolar epithelial cell (AEC) injury leading to cell death is involved in the process of fibrosis development during idiopathic pulmonary fibrosis (IPF). Among regulated/programmed cell death, the excessive apoptosis of AECs has been widely implicated in IPF pathogenesis. Necroptosis is a type of regulated/programmed necrosis. A multiprotein complex composed of receptor-interacting protein kinase-1 and -3 (RIPK1/3) plays a key regulatory role in initiating necroptosis. Although necroptosis participates in ...
