Previous study has demonstrated that activation of the mammalian target of rapamycin (mTOR) pathway in endothelial cells (ECs) results in the formation of chronic vascular lesions associated with antiphospholipid syndrome (APS). In addition, it has been shown that stimulation of monocytes and ECs by antiphospholipid antibodies (aPL) leads to a prothrombotic and proinflammatory state and up-regulated expression of tissue factor (TF) and inflammatory cytokines. However, the role of mTOR in pathogenic mechanisms of APS remains largely unexplored...

IL-4 receptor (IL-4R) is commonly up-regulated on tumor cells, and interactions between the receptor and Interleukin-4 (IL-4) can induce the expression of anti-apoptotic proteins, including Bcl-xL. This contributes to tumor cell survival and their resistance to chemotherapy. In this study, we exploited IL-4R-targeted delivery of Bcl-xL siRNA to IL-4R-expressing tumor cells in order to sensitize them to chemotherapy. To target IL-4R, an IL-4R-binding peptide, IL4RPep-1, was attached to branched polyethyleneimine-superparamagnetic iron oxide nanoparticles (BPEI-SPION)...

INTRODUCTION: Although tumor metastases remain significant drivers of mortality, the genetic factors that increase the risks of metastases are not fully identified. Interleukin 6 (IL-6) has emerged as an important factor in breast cancer progression with IL-6 single nucleotide polymorphism (SNP) variants shown to affect survival. We hypothesized that SNPs of the IL-6 promoter at rs1800795 in breast cancer patients are associated with distant metastases. METHODS: We performed an initial case-control study using Vanderbilt University Medical Center's BioVU, a genomic biobank linked to de-identified electronic medical records in the Synthetic Derivative database, to identify germline SNPs that may predict the development of metastatic disease to any site from any solid tumor including breast cancer...

Cisplatin is an effective anticancer chemotherapeutic agent, but the use of cisplatin in the clinic is severely limited by side effects. Nephrotoxicity is a major factor that contributes to the side effects of cisplatin chemotherapy. The aim of this research was to survey the nephroprotective effects of anthocyanin from the fruits of Panax ginseng (GFA) in a murine model of cisplatin-induced acute kidney injury. We observed that pretreatment with GFA attenuated cisplatin-induced elevations in blood urea nitrogen and creatinine levels and histopathological injury induced by cisplatin...

Many studies have reported that lutein may exert its biological activities, including anti‑inflammation, anti‑oxidase and anti‑apoptosis, through effects on reactive oxygen species (ROS). Thus, lutein may prevent the damaging activities of ROS in cells. The current study investigated the effect of lutein against severe traumatic brain injury (STBI) and examined the mechanism of this protective effect. Sprague‑Dawley rats were randomly divided into 5 groups: Control group, STBI model group, 40 mg/kg lutein‑treated group, 80 mg/kg lutein‑treated group and 160 mg/kg lutein‑treated group...

Isorhamnetin (ISH) is a flavonoid primarily obtained from the fruit of Hippophae rhamnoides L., which possesses anti‑inflammatory properties. However, the effect of ISH on the expression of inflammatory mediators in response to interleukin (IL)‑1β stimulation has not been elucidated. The present study investigated the effects of ISH on the expression of inflammatory mediators in human chondrocytes, induced by IL‑1β. The results of the present study demonstrated that pretreatment with ISH inhibited the expression of stromelysin‑1 and collagenase 3 in chondrocytes, induced by IL‑1β...

Acquired aplastic anemia, the prototypical bone marrow failure disease, is characterized by pancytopenia and marrow hypoplasia. Most aplastic anemia patients respond to immunosuppressive therapy, usually as anti-thymocyte globulin and cyclosporine, but some relapse on cyclosporine withdrawal or require long-term administration of cyclosporine to maintain blood counts. In the current study, we tested efficacy of rapamycin as a new or alternative treatment in mouse models of immune-mediated bone marrow failure...

OBJECTIVES: According to a report by the United States National Health and Nutrition Examination Survey, nearly 60% of patients with diabetes have more than one complication caused by chronic diabetes. Type 2 diabetes is a multifactorial metabolic disorder that accounts for more than 95% of people with diabetes and usually requires multitargeted therapeutic interventions. It arises due to insufficient insulin secretion or its action or both. Recently, we reported that the oral administration of gymnemic acid, trigonelline and ferulic acid in the ratio of 2:3:1 (GTF-231), a mixture of 3 phytoingredients at a concentration of 300 mg/kg body weight significantly improved the glucose homeostasis in rats with low-dose streptozotocin-induced type 2 diabetes that were fed with high-fat diet...

Historical pathogen burdens are examined as possible triggers for genetic adaptation. Evidence of adaptation emerges for the acid phosphatase locus 1 (ACP1), interleukin-6 (IL6), interleukin-10 (IL10 ), human leukocyte antigen (HLA) polymorphisms, along with a measure of heterozygosity over 783 alleles. Results are robust to controlling for the physical and historical environment humans faced, and to endogeneity of the historical pathogen burden measure. The present study represents a proof-of-concept which may pave the way to the analysis of future aggregate measures coming from whole-genome sequencing/genotyping data...

STUDY OBJECTIVES: Excessive daytime sleepiness (EDS) is a key symptom of obstructive sleep apnea (OSA). The Psychomotor Vigilance Task (PVT) has been suggested as an objective easy-to-use, inexpensive alternative to the Multiple Sleep Latency Test (MSLT) to measure EDS. In patients with OSA, physiological sleepiness, but not subjective EDS (Epworth Sleepiness Scale [ESS]), has been associated with increased levels of the sleep- inducing proinflammatory cytokine interleukin-6 (IL-6). The goal of this study was to assess the association of PVT with objectively measured sleepiness (MSLT) and subjectively measured sleepiness (ESS) and IL-6 levels in patients with OSA...

The Maillard reaction is a nonenzymatic reaction between an amino acid and a reducing sugar that usually occurs upon heating. This reaction occurs routinely in cooking, generates numerous products, which are collectively referred to as Maillard reaction products (MRPs) contributing to aroma and color features. Advanced glycation end-products (AGEs) transformed from MRPs are participated in many types of inflammation reaction. In this study, various sugar-amino acid MRPs were prepared from three different amino acids (lysine, arginine, and glycine) and sugars (glucose, fructose, and galactose) for 1 h with heating at 121 °C...
