The Potential Therapeutic Value of Renin-Angiotensin System Inhibitors in the Treatment of Colorectal Cancer.

Colorectal cancer is the third most common cancer globally. Despite extensive preclinical and clinical studies, it is still among the leading causes of cancer-related death, and a need for new therapeutic options is required. The renin-angiotensin system plays an important role in regulating blood pressure and cell growth.

Therapeutic potential of active components of saffron in post-surgical adhesion band formation.

Background: Abdominal adhesions are common and often develop after abdominal surgery. There are currently no useful targeted pharmacotherapies for adhesive disease. Saffron and its active constituents, Crocin and Crocetin, are wildly used in traditional medicine for alleviating the severity of inflammatory or malignant disease.

Here, we have investigated the therapeutic potency of EW-7197, a transforming growth factor-β type I receptor kinase inhibitor, against postsurgical adhesion band formation. Our results showed that this pharmacological inhibitor prevented the frequency and the stability of adhesion bands in mice model. We have also shown that downregulation of proinflammatory cytokines, reduce submucosal edema, attenuation of proinflammatory cell infiltration, inhibition of oxidative stress, decrease in excessive collagen deposition, and suppression of profibrotic genes at the site of surgery are some of the mechanisms by which EW-7197 elicits its protective responses against adhesion band formation.

Stem cell therapy: A novel approach for myocardial infarction.

Myocardial infarction (MI) is a major cause of morbidity and mortality worldwide. Until recently, it was thought that myocardium was not able to repair itself, but studies have now shown that resident cardiac stem cells have regenerative capacity, and stem cell therapy may be a novel approach for cardiac muscle repair and regeneration. Stem cell-derived paracrine factors have been shown to regulate ventricular remodeling, inflammation, apoptosis, cardiomyocytes regeneration, and neovascularization in regions of infarcted cardiac tissue.

CD73; a key ectonucleotidase in the development of breast cancer: Recent advances and perspectives.

Tumor cell invasion and metastasis are the definitive cause of mortality in breast cancer (BC). Hypoxia and pro-inflammatory cytokines upregulate the CD73 gene in the tumor microenvironment. Subsequently, CD73 triggers molecular and cellular signaling pathways by both enzymatic and nonenzymatic pathways, which finally leads to breast tumor progression and development.

EW-7197 attenuated the colitis disease activity index by improving rectal bleeding, body weight, and degree of stool consistency.

The diagnostic and prognostic value of copeptin in cardiovascular disease, current status, and prospective.

Copeptin is a glycosylated peptide derived from the cleavage of the precursor of arginine-vasopressin. In contrast to arginine-vasopressin, copeptin is a stable molecule and can easily be measured using a simple rapid assay. The serum concentration of copeptin is increased in several clinical conditions, including hypertension, chronic kidney disease, and, of special interest in this review, in cardiovascular diseases.

Prevalence of combined and noncombined dyslipidemia in an Iranian population.

Background: Combination of dyslipidemic phenotypes, including elevated plasma levels of low-density lipoprotein cholesterol (LDL-C), elevated plasma triglycerides (TG), and decreased low-density lipoprotein cholesterol (HDL-C) concentrations, is important because of the association of individual phenotypes with increased risk of cardiovascular disease (CVD). We investigated the prevalence of combined dyslipidemias and their effects on CVD risk in an Iranian large population.

Method: A total of 9847 individuals were recruited as part of the Mashhad Stroke and Heart Atherosclerotic Disorders (MASHAD) cohort study.

Crocus sativus a natural food coloring and flavoring has potent anti-tumor properties.

Background: Saffron, the dried stigmas of Crocus sativus L., is a highly valued agricultural product that is used mainly as a food coloring and flavoring agent. Three main secondary metabolites of Crocus sativus including crocin, picrocrocin, and safranal are responsible for the color, the bitter taste and for the odor and aroma, respectively.

Association between serum uric acid, high sensitive C-reactive protein and pro-oxidant-antioxidant balance in patients with metabolic syndrome.

Depression and anxiety symptoms are associated with white blood cell count and red cell distribution width: A sex-stratified analysis in a population-based study.

Background: Depression and anxiety are two common mood disorders that are both linked to systemic inflammation. Increased white blood cell (WBC) count and red cell distribution width (RDW) are associated with negative clinical outcomes in a wide variety of pathological conditions. WBC is a non-specific inflammatory marker and RDW is also strongly related to other inflammatory markers.

Adenosine: An endogenous mediator in the pathogenesis of gynecological cancer.

Extracellular concentration of adenosine increases in the hypoxic tumor microenvironment. Adenosine signaling regulates apoptosis, angiogenesis, metastasis, and immune suppression in cancer cells. Adenosine-induced cell responses depend upon different subtypes of adenosine receptors activation and type of cancer.

Depression and anxiety both associate with serum level of hs-CRP: A gender-stratified analysis in a population-based study.

Background: Depression and anxiety are two important mood disorders that are frequently associated with chronic diseases such as cardiovascular diseases (CVDs). Hyper-inflammation is related to both CVDs and psychological conditions such as depression and anxiety. Therefore, inflammation may partially explain the relationship between depression and cardiovascular disease.

Role of adenosine signaling in the pathogenesis of breast cancer.

The plasma level of adenosine increases under ischemic and inflamed conditions in tumor microenvironment. Adenosine elicits a range of signaling pathways in tumors, resulting in either inhibition or enhancement of tumor growth depending upon different subtypes of adenosine receptors activation and type of cancer. Metabolism of adenosine-5'-triphosphate (ATP) and its derivatives including adenosine is dysregulated in the breast tumor microenvironment, supporting the role of this metabolite in the pathogenesis of breast cancer.

Background: Hypertension (HTN) is a risk factor for stroke, renal failure, and cardiovascular disease. The association between biochemical and hematological parameters with high blood pressure may provide a more precise approach to risk prediction conferred by HTN in these patients.

Objective: The aim of current study was to explore whether biochemical and hematological parameters are associated with HTN in a cohort study with a 7-year follow-up.

Proinflammatory signaling functions of thrombin in cancer.

Thrombin-induced activation of protease-activated receptors (PARs) represents a link between inflammation and cancer. Proinflammatory signaling functions of thrombin are associated with several inflammatory diseases including neurodegenerative, cardiovascular, and of special interest in this review cancer. Thrombin-induced inflammatory responses up-regulates expression of cytokines, adhesion molecules, angiogenic factors, and matrix-degrading proteases that facilitate tumor cells proliferation, angiogenesis, invasion, and metastasis.

Role of Wnt5a in the Pathogenesis of Inflammatory Diseases.

Wnt5a initiates pro-inflammatory responses through activation of non-canonical Wnt signaling pathway. Pro-inflammatory functions of Wnt5a trigger pro-inflammatory signaling cascades and increase secretion of pro-inflammatory cytokines and chemokines. Wnt5a as a potent signaling molecule is strongly implicated in a number of diseases including cancer, diabetes, metabolic disorders, and of special interest in this review, inflammatory diseases.

Role of thrombin in the pathogenesis of central nervous system inflammatory diseases.

Thrombin initiates proinflammatory signaling responses through activation of protease-activated receptors (PARs) in in vitro and in vivo systems. Proinflammatory signaling function of thrombin increases secretion of proinflammatory cytokines and chemokines, triggers vascular permeability, promotes leukocyte migration, and induces adhesion molecule expression. Thrombin as a potent signaling molecule is strongly implicated in a number of proinflammatory disorders including severe sepsis, cancer, cardiovascular disease, and of special interest in this review neurodegenerative disorders.
