AIM: Inhibition of cyclooxygenase-2 (COX-2) is proposed as a treatment option in several cancer types. However, in non-small cell lung cancer (NSCLC), phase III trials have failed to demonstrate a benefit of adding COX-2 inhibitors to standard chemotherapy. The aim of this study was to analyze COX-2 expression in tumor and stromal cells as predictive biomarker for COX-2 inhibition. METHODS: In a multicenter phase III trial, 316 patients with advanced NSCLC were randomized to receive celecoxib (400 mg b...

BACKGROUND: Beneficial effects of aspirin and non-aspirin nonsteroidal anti-inflammatory drugs (NSAIDs) against recurrent colorectal adenomas have been documented in systematic reviews; however, the results have not been conclusive. Uncertainty remains about the appropriate dose of aspirin for adenoma prevention. The persistence of the protective effect of NSAIDs against recurrent adenomas after treatment cessation is yet to be established. METHODS: Our objective was to update and systematically evaluate the evidence for aspirin and other NSAIDs on the incidence of recurrent colorectal adenomas taking into consideration the risks of random error and to appraise the quality of evidence using GRADE (The Grading of Recommendations, Assessment, Development and Evaluation) approach...

BACKGROUND: The controversy over electrotherapy for patients aged >80 years occurs already at the stage of qualification for this treatment type and concerns optimal device selection, the implantation strategy, and the overall benefit from pacemaker therapy. The group also has a considerable number of cardiovascular risk factors, and the data from the literature on the impact of the pacing mode on the remote prognosis of this group are ambiguous. OBJECTIVE: Assessment of the risk factors for death among patients with implanted pacemakers >80 years of age in a 4-year follow-up...

Background : Clinical trials have shown cardiovascular benefits and potential risks from sodium glucose co-transporter 2 inhibitors (SGLT2i). Trials may have limited ability to address individual endpoints or safety concerns. Methods : We performed a population-based cohort study among type 2 diabetes patients with established cardiovascular disease newly initiated on antihyperglycemic agents (AHAs) within the US Department of Defense Military Health System between 4/1/2013 and 12/31/2016. Incidence rates, hazard ratios (HRs), and 95% confidence intervals (CIs) for time to first composite endpoint of all-cause mortality (ACM) and hospitalization for heart failure (HHF) event, major adverse cardiovascular events (MACE; defined as ACM, nonfatal myocardial infarction, and nonfatal stroke), and individual endpoints were evaluated using conditional Cox models comparing new SGLT2i users with other AHAs...

mPGES-1, a glutathione-dependent membrane protein is involved in the last step of PGE2 production and has been well recognized as a strategic target for the development of anti-inflammatory and anti-cancer agents. It has been proven to selectively control the PGE2 levels induced by inflammatory stimuli, with neither affecting PGE2 constitutively produced, nor homeostatic prostanoids, so that its modulation can represent a better strategy to control PGE2 related disorders, compared to the use of the classical anti-inflammatory drugs, endowed with severe side effects...

Sulfur mustard (SM, bis(2-chloroethyl sulfide) is a potent vesicating agent known to cause skin inflammation, necrosis and blistering. Evidence suggests that inflammatory cells and mediators that they generate are important in the pathogenic responses to SM. In the present studies we investigated the role of mast cells in SM-induced skin injury using a murine vapor cup exposure model. Mast cells, identified by toluidine blue staining, were localized in the dermis, adjacent to dermal appendages and at the dermal/epidermal junction...

Heterotopic ossification (HO) is prevalent after total hip arthroplasty (THA). Oral nonsteroidal anti-inflammatory drugs and cyclooxygenase-2 (COX-2) inhibitors have reduced the incidence of HO; however, to the authors' knowledge, no studies have reported the incidence and severity of HO with a pain protocol highlighted by celecoxib in the pre- and postoperative period with a posterolateral approach. Between October 2014 and October 2015, a retrospective study was conducted of 687 consecutive primary THAs with minimum 1-year follow-up performed between January 2009 and December 2013...

Respiratory tract infections and pneumonia are major causes of morbidity and mortality in burn victims, however, limited studies have examined the effects of burn injury on airway epithelium. The current study examines the effect of scald burn injury on rat tracheal epithelium at 5 days after injury and tests the hypothesis that treatment with febuxostat (FBX), an inhibitor of xanthine oxidase (XO), can be protective of cell homeostasis. Sprague Dawley rats were randomly divided into uninjured (sham), injured (control) and injured and FBX treated groups, n = 8...

Chagas disease (Cd) or American human trypanosomiasis is caused by Trypanosoma cruzi and affects ~7 million people, mostly in Latin America. The infective trypomastigote forms of the parasite can invade several human blood cell populations, including monocytes and dendritic cells (DC). Although these cells display a wide functional diversity, their interactions with T. cruzi via cyclooxygenase (COX) and cyclic adenosine monophosphate (cAMP) dependent pathways have not been analyzed. To exploiting this mechanism, DC-enriched peripheral human blood mononuclear cell populations (DC-PBMC) were used as our model...

BRAFV600 mutations occur in multiple nonmelanoma tumors, but no US Food and Drug Administration-approved BRAF-targeted therapies exist for these cancers. BRAF inhibitor vemurafenib was recently found to demonstrate activity across various BRAF-mutated nonmelanoma cancer types. However, most tumors ultimately become resistant to BRAF-targeted monotherapy. To identify whether co-occurring genomic alterations drive resistance to BRAF-targeted therapies, we analyzed next-generation sequencing data from 30 advanced BRAF-mutated nonmelanoma cancers treated with BRAF inhibitor monotherapy...

We have identified a novel PDE2 inhibitor series using fragment-based screening. Pyrazolopyrimidine fragment 1, while possessing weak potency (Ki = 22.4 μM), exhibited good binding efficiencies (LBE = 0.49, LLE = 4.48) to serve as a start for structure-based drug design. With the assistance of molecular modeling and X-ray crystallography, this fragment was developed into a series of potent PDE2 inhibitors with good physicochemical properties. Compound 16, a PDE2 selective inhibitor, was identified that exhibited favorable rat pharmacokinetic properties...

Radiotherapy resistance is an enduring major setback in lung cancer therapy, and is responsible for a large proportion of treatment failures. In previous years, cyclooxygenase-2 (COX-2) has frequently been reported to promote tumor occurrence and development, suggesting a potential role in radiotherapy resistance. To investigate whether COX-2 inhibitors can be applied in radiosensitization, an MTT assay was performed to examine cell viability after X-ray radiation in the presence or absence of the specific COX-2 inhibitor Celecoxib...

Multi-drug resistance protein 4 (MRP4), a potential chemotherapeutic target as well as a transporter for endogenous signaling molecules (e.g. prostaglandins), is known to be expressed in the endometrium, although its possible role(s) in the physiology of the endometrium remains unknown. Here, we show that MRP4 is upregulated at implantation window and localized to the basolateral membrane of the endometrial epithelium, the interface between the epithelium and stroma in mice. In human endometrial epithelial cells, MRP4 expression is upregulated by ENaC activation and the inhibition of MRP4 blocks ENaC-dependent PGE2 release as well as phosphorylation of CREB...
