BACKGROUND AND AIMS: Exposure to psychosocial stress is a risk factor for cardiovascular disorders. Because the glucagon-like peptide-1 (GLP-1) receptor (GLP-1R) agonist prevents cardiovascular injury, we investigated the beneficial effects and mechanism of the GLP-1 analogue exenatide on stress-related vascular senescence and atherosclerosis in apolipoprotein E-deficient (ApoE(-/-)) mice fed a high-fat (HF) diet. METHODS: ApoE(-/-) mice fed the HF diet were assigned to non-stressed and immobilized-stress groups for 12 weeks...

It is well-accepted that inflammation plays an important role in the development of cardiac remodeling and that therapeutic approaches targeting inflammation can inhibit cardiac remodeling. Although a large amount of evidence indicates that activation of α7 nicotinic acetylcholine receptor (α7nAChR) causes an anti-inflammatory effect, the role of α7nAChR in cardiac remodeling and the underlying mechanism have not been established. To investigate the effect of the specific α7nAChR agonist, PNU282987, on cardiac remodeling induced by isoproterenol (ISO 60 mg/kg/d) in mice, the cardiomyocyte cross-sectional area (CSA) and collagen volume fraction were evaluated by hematoxylin and eosin (HE) and Masson staining, respectively...

Following myocardial infarction (MI), degradation of extracellular matrix (ECM) by upregulated matrix metalloproteinases (MMPs) especially MMP-2 decreases tissue mechanical properties, leading to cardiac function deterioration. Attenuation of cardiac ECM degradation at the early stage of MI has the potential to preserve tissue mechanical properties, resulting in cardiac function increase. Yet the strategy for efficiently preventing cardiac ECM degradation remains to be established. Current preclinical approaches have shown limited efficacy due to low drug dosage allocated to the heart tissue, dose-limiting side effects, and cardiac fibrosis...

Survival of trophoblast cells in the low oxygen environment of human placentation requires metalloproteinase-mediated shedding of HBEGF and downstream signaling. A matrix metalloproteinase (MMP) antibody array and quantitative RT-PCR revealed upregulation of MMP2 post-transcriptionally in human first trimester HTR-8/SVneo trophoblast cells and placental villous explants exposed to 2% O2. Specific MMP inhibitors established the requirement for MMP2 in HBEGF shedding and upregulation. Because α-amanitin inhibited the upregulation of HBEGF, differentially expressed genes were identified by next-generation sequencing of RNA from trophoblast cells cultured at 2% O2 for 0, 1, 2 and 4 h...

Tricetin is a flavonoid derivative and a potent anti-inflammatory and anticancer agent. However, the molecular mechanism underlying the effects of tricetin on human oral cancer cell migration remains unclear. The cell migration and invasion abilities of three oral cancer cell lines (SCC-9, HSC-3, and OECM-1) were analyzed using Boyden chamber migration assays. Our results demonstrated that tricetin attenuates 12-O-tetradecanoylphorbol-13-acetate-induced SCC-9, HSC-3, and OECM-1 cell invasiveness and migration by reducing matrix metalloproteinase (MMP)-9 enzyme activity...

Increasing evidence has demonstrated that miRNAs play a critical role in tumor development and progression. Previous studies have revealed that miR-106a is abnormally expressed in various cancers. However, its function and underlying mechanism in cervical cancer (CC) remains unknown. In this study, we confirmed that the expression of miR-106a was significantly upregulated in both CC cell lines and tissues by qRT-PCR. The increased expression of miR-106a was obviously associated with adverse prognostic features...

Sjögren's syndrome (SS) is an autoimmune disease characterized by hypofunction of the salivary and lachrymal glands. Main clinical features of SS are sicca symptoms, due to the altered glandular function. Also, in advanced stages, bilateral swelling of the parotid glands can be noted, indicative of severe glandular involvement. Phenotypic expression of various mononuclear cells present in the affected tissue offers additional insight into cellular proliferation, survival, migration, antibody secretion and also the potential of forming tertiary lymphoid tissue, i...

Pterygium is a common ocular surface disease induced by a variety of factors. The exact pathogenesis of pterygium remains unclear. Numbers of genes and proteins are discovered in pterygium and they function differently in the occurrence and development of this disease. We searched the Web of Science and PubMed throughout history for literatures about the subject. The keywords we used contain pterygium, gene, protein, angiogenesis, fibrosis, proliferation, inflammation, pathogenesis and therapy. In this review, we summarize the aberrant expression of a range of genes and proteins in pterygium compared with normal conjunctiva or cornea, including growth factors, matrix metalloproteinases and tissue inhibitors of metalloproteinases, interleukins, tumor suppressor genes, proliferation related proteins, apoptosis related proteins, cell adhesion molecules, extracellular matrix proteins, heat shock proteins and tight junction proteins...

Endometrium is the only tissue in the human body subject to cyclic transformations under the influence of ovarian steroid hormones. As estradiol and progesterone balance throughout the physiological menstrual cycle changes, so does the expression of metalloproteinases (MMPs). These endopeptides are responsible for keeping the balance between the process of synthesis and degradation of extracellular matrix proteins. Thus, MMP's take part in sustaining physiological stability of the endometrium. A number of MMPs found in the endometrial tissue and their activity is related to menstrual cycle phase...

Preeclampsia is a severe pregnancy complication globally, characterized by poor placentation triggering vascular dysfunction. Matrix metalloproteinases (MMPs) exhibit proteolytic activity implicated in the efficiency of trophoblast invasion to the uterine wall, and a dysregulation of these enzymes has been linked to preeclampsia. A decrease in MMP-2 and MMP-9 interferes with the normal remodeling of spiral arteries at early pregnancy stages, leading to the initial pathophysiological changes observed in preeclampsia...

This study described and histologically characterized a cyst-like lesion (CLL) at the chondro-osseous junction. Rat knees (n = 12), with or without excessive running-induced osteoarthritis (OA), were used for counting the incidence, morphological measurements, immunohistochemistry of the CLL. A typical CLL, appearing as a void space in the matrix, was located on the tidemark at the chondro-osseous junction. The content of the CLL included types II and VI collagen, proteoglycans but not intact chondrocytes. At least one CLL was found in 5/6 osteoarthritic knees and only 2/6 in the non-osteoarthritic knees...

Abdominal aortic aneurysm (AAA) is a vascular disease involving gradual dilation of the abdominal aorta. Recent studies suggest that nicotine, which is a primary component in cigarette smoke, is closely associated with the development and rupture of an AAA. Nicotine accelerates AAA development through the weakening of the vascular wall by increasing oxidative stress and matrix metalloproteinase (MMP)-2 expression. However, little is known about preventing the AAA induced by nicotine. A non-surgical means of preventing the weakening of the vascular wall before the onset of AAA by functional food factors would be a valuable option over surgery...
