Mycoplasma species are contagious bacteria and Mycoplasma bovis mastitis is a serious productivity problem on dairy farms. Bovine mammary epithelial cells (bMEC) play an important role in the elimination of pathogens, but the effect of M. bovis on bMEC has not been fully clarified. To better understand the immune response against intramammary infection by M. bovis, we used microarray analysis to examine and profile mRNA expression in bMEC after stimulation with M. bovis. We also compared the effects of M. bovis, Staphylococcus aureus and Escherichia coli on immune-related mRNA expression in bMEC...

The anticancer immune defense mechanism involves humoral and cellular responses. The main effector mechanisms of antitumor responses involve the following: the activity of cytotoxic T cells; the activation of macrophages and neutrophils; the activity of cytokines secreted by T cells; and natural killer cell activity. Selected cell populations are responsible for the stimulation or suppression of the immune system against tumor cells. Therefore, the aim of the present study was to evaluate the location, extent and composition of the cellular inflammatory infiltration of tumors in patients with colorectal cancer (CRC)...

Protocadherin-8 (PCDH8), a member of the protocadherin superfamily of proteins, is frequently lost in numerous types of cancer. However, the role that PCDH8 serves in human glioma, and the molecular mechanisms underlying this, remain unclear. Data from the present study demonstrated that the expression levels of PCDH8 mRNA and protein were significantly decreased in human glioma tissue compared with normal brain tissue. This suggested that PCDH8 is associated with the development of glioma. Thus, the role of PCDH8 in glioma cell proliferation was investigated by silencing and overexpressing PCDH8 in U251 glioma cells...

Metastasis of lung carcinoma cells is a major cause of organ failure and mortality of patients with lung cancer. Lung mast cells are a type of immune cell which reside in the respiratory mucosa. High numbers of mast cells are associated with the majority of common types of cancer; however, the effects of mast cells on cancer remain unclear. In the present study, the effects of mast cell chymase (MCC) on the proliferation and adhesion of the lung carcinoma cell lines A549 and H520 was investigated. After 24 h of treatment, the highest dose of MCC (50 mU/ml) decreased the proliferation rate of A549 and H520 cells, whereas the lowest dose of MCC (5 mU/ml) resulted in a small increase in the viability...

Non-Invasive Brain Stimulation (NIBS) is a relatively new therapeutic approach that has shown beneficial effects in Autism Spectrum Disorder (ASD). One question to be answered is how enduring its neuromodulatory effect could be. Twenty-four patients with ASD (mean age: 12.2 years) received 20 sessions of NIBS over the left dorsolateral prefrontal cortex (L-DLPFC). They were randomized into two groups with two (G1) or three (G2) clinical evaluations before NIBS. Both groups had a complete follow-up at six months after the intervention, with the aim of determining the short-term outcome using the total score on the Autism Behavior Checklist, Autism Treatment Evaluation Checklist, and the Autism Diagnostic Interview...

Nowadays, the role of miRNA in tumorigenesis has been largely reported. It was found that miR-506 might be associated with tumorigenesis of various cancers. The present study was aimed to investigate the character of miR-506 and some related factors in human osteosarcoma (OS) carcinogenesis. The expression level of miR-506 was downregulated in OS compared with the normal control group by RT-PCR, both in vivo and in vitro. In addition, IL-1β stimulation decreased the expression of miR-506. MiR-506 interfered with JAG1 gene transcription throughmiR-506 binding to the 3'-UTR region of JAG1 gene...

OBJECTIVE: Chronic high protein intake leads to an increase in reactive oxygen species (ROS) generation. However, there is no data on the impact of high-protein diet on the antioxidant barrier, oxidative stress and secretory function in the salivary glands of healthy individuals. DESIGN: 16 male Wistar rats were randomly divided into 2 groups (n=8): normal protein (C) and high-protein diet (HP) for 8 weeks. Salivary antioxidants: peroxidase (Px), catalase (CAT), superoxide dismutase 1 (SOD 1), uric acid (UA), total antioxidant status (TAS), total oxidant status (TOS) and the oxidative stress index (OSI), as well as protein carbonyls (PC), 4-hydroxynonenal protein adduct (4-HNE protein adduct), 8-isoprostanes (8-isoP), 8-hydroxy-2'-deoxyguanosine (8-OHdG) and protein content were determined in the salivary glands and plasma...

Recently, ultra-weak photon emission (UPE) was developed as a novel tool for measuring oxidative metabolic processes, as its generation is related to reactive oxygen species (ROS). Both an imbalance in ROS or the uncontrolled production of ROS can lead to oxidative stress, which is commonly associated with many diseases. In addition to playing several biological functions, the thiol amino acid glutathione has an important antioxidant function in the body's defense against ROS. Specifically, glutathione is an important endogenous antioxidant that helps maintain oxidant levels...

BACKGROUND: High glucose concentrations influence the functional and structural development of the peritoneal membrane. We previously reported that the oral administration of astaxanthin (AST) suppressed peritoneal fibrosis (PF) as well as inhibited oxidative stress, inflammation, and epithelial-mesenchymal transition (EMT) of peritoneal mesothelial cells (PMCs) in a chlorhexidine-induced PF rat model. This suggests that oxidative stress induction of EMT is a key event during peritoneal damage...

Vitamin D that is synthesized in the skin or is ingested undergoes sequential steps of metabolic activation via a cascade of cytochrome P450 enzymatic hydroxylations in the liver and kidney to produce 1α,25-dihydroxyvitamin D (1α,25(OH)2 D). There are many tissues that are able to synthesize 1α,25(OH)2 D, but the biological significance of extrarenal hydroxylases is unresolved. Human marrow-derived mesenchymal stem cells (marrow stromal cells, hMSCs) give rise to osteoblasts, and their differentiation is stimulated by 1α,25(OH)2 D...
