Periodontitis is a prevalent and chronic inflammatory disease that is interrelated with systemic health. Periodontitis can be promoted by tumor necrosis factor α (TNF-α). Cementum, a vital part of the periodontium, is a bone-like mineralized tissue that is produced by cementoblasts. Our laboratory previously revealed that TNF-α inhibits cementoblast differentiation and mineralization. However, how TNF-α modulates cementoblast differentiation and mineralization remains largely unknown. MicroRNA-155 (miR-155) is induced and regulates TNF-α-inhibited osteogenic differentiation...

Arsenite is a well-documented human lung carcinogen but the detailed mechanisms of carcinogenesis remain unclear. In this study, human bronchial epithelial (16-HBE) cells were continuously exposed to 2.5μM arsenite for about 13 weeks to induce the phenotypes of malignant transformation. Our results showed that Nrf2 expression was gradually decreased whereas no significant change was observed on NF-κB activation with increased time of arsenite exposure. To test the roles of Nrf2-meidtaed oxidative damage in the arsenite-induced malignant transformation, we compared the levels of cGMP, PKG and oxidative damage-related indicators between arsenic-transformed cells and control cells...

microRNA-155 (miR-155) is implicated in regulating B-cell activation and survival that is important in systemic lupus erythematosus (SLE) pathogenesis. PU.1, a target for miR-155, is a crucial regulator of B-cell development and enhances Tumour-Necrosis-factor-alpha (TNF-α) expression. TNF-α induces the expression of B-cell-activating-factor (BAFF). BAFF is reported to increase the expression of the autoimmunity marker; CD19. This study aimed to investigate the regulation of expression of PU.1 in pediatric-systemic-lupus-erythematosus (pSLE) patients by miR-155, and hence evaluate its impact on TNF-α/BAFF/CD19 signalling pathway...

Diabetes leads to amputation in approximately 15% to 20% of patients and is associated with high morbidity and mortality. Thus, improving the quality of wound healing in this condition is essential. Diabetes is associated with acute/chronic inflammation affecting all organs especially the foot, while, inhibition of microRNA-155 (miR-155) has been reported to improve or reduce inflammatory situation. However, the role of miR-155 inhibition in promoting diabetic wound healing is not clear. To further study the potential benefit of miR-155 inhibition, a study of male Sprague-Dawley rats was conducted and diabetes was induced by injection of streptozotocin...

As an evolutionarily conserved metabolic process, autophagy is involved in the process of atherosclerosis (AS). MicroRNA-155 (miR-155), a multifunctional miRNA, plays an important role in many physiological and pathological conditions, including AS and autophagy. However, the effect of miR-155 on the regulation of autophagy in endothelial cells has not been reported to date. Therefore, the objective of our study was to investigate the role of miR-155 in autophagy induced by oxidized low-density lipoprotein (ox-LDL) in human umbilical vein endothelial cells (HUVECs)...

Novel therapeutic interventions for obesity and comorbid conditions require knowledge of the molecular elements playing a role in the development of obesity. Chronic low-grade inflammation has been consistently reported in obese individuals. In this study, we first determined whether key molecular modulators of inflammation, microRNA-155 (mir-155) and microRNA-146a (miR-146a), are regulated by an obesogenic diet within brain regions associated with reward, metabolism and energy balance. C57BL/6J mice were chronically exposed to a high fat diet (HFD) or a standard chow (CTL)...

MicroRNA-155 (miR-155) is overexpressed in numerous human cancer types and has an oncogenic role. Previous study has revealed that miR-155 serves an important role in the progression of clear-cell renal cell carcinoma (ccRCC); however, the underlying mechanism was not completely clarified. The present study aimed to investigate the biological role of miR-155 in ccRCC and the underlying molecular mechanisms. The expression of miR-155 in 20 ccRCC and adjacent normal kidney tissues was determined by PCR. After downregulation of miR-155 expression by miR-155 inhibitor, cell growth was assessed by MTT and colony formation assays...

MicroRNA (miR)-155 is upregulated in breast cancer cells and in sera of patients with breast cancer, but its clinical relevance remains uncertain. The objective of the present effort was to address the transcriptional regulation of miR-155. A bioinformatics analysis of public datasets validated upregulation of miR-155 in tumor cells of patients with breast cancer, particularly those who were at early stages and had triple-negative cancers. The expression profiling and clinical relevance of miR-155 in tumor cells and blood cells were characterized by TaqMan miR assays and, in plasma and exosomes, by nest-quantitative PCR analysis...

BACKGROUND/AIMS: Men with terminal renal failure are often infertile. Anti-müllerian hormone (AMH), a marker of Sertoli cell function, is decreased among men with chronic kidney disease (CKD). Recently, a microRNA, miR-155, has been shown to be a potential marker for subfertility. We studied miR-155 and semen parameters in patients with CKD who were not yet on dialysis. We also aimed to study possible associations between AMH, miR-155, and semen parameters to evaluate them as markers of fertility...

Genistein plays an important role in the prevention of atherosclerosis. However, the underlying mechanisms have not been fully investigated. In this study, human umbilical vein endothelial cells (HUVECs) were pretreated with genistein (10, 100, and 1000 nM) for 6 h and then exposed to ox-LDL (50 mg/L) for another 24 h. Results showed that ox-LDL induced the expressions of E-selectin, P-selectin, monocyte chemotactic protein-1, interleukin-8, vascular adhesion molecule-1, and intercellular adhesion molecule-1, which were counteracted by genistein...

Cardiac dysfunction is correlated with detrimental prognosis of sepsis and contributes to a high risk of mortality. After an initial hyperinflammatory reaction, most patients enter a protracted state of immunosuppression (late sepsis) that alters both innate and adaptive immunity. The changes of cardiac function in late sepsis are not yet known. MicroRNA-155 (miR-155) is previously found to play important roles in both regulations of immune activation and cardiac function. In this study, C57BL/6 mice were operated to develop into early and late sepsis phases, and miR-155 mimic was injected through the tail vein 48 h after cecal ligation and puncture (CLP)...

Excess alcohol consumption and the associated development of alcoholic liver disease (ALD) are major public health challenges worldwide. Since patients with the severe stages of ALD no longer benefit from clinical therapies, early warning of ALD holds significant promise for increasing the cure rate of ALD. Herein, we develop a bicolor fluorescent nanoprobe for dynamically monitoring the conversion process of alcohol-induced fatty liver to steatohepatitis in vivo through simultaneous imaging of microRNA 155 and osteopontin mRNA, which are related to fatty liver and steatohepatitis, respectively...

The aim of this work was to explore the microRNA profile and the effect of microRNA-155 on apoptosis in the spleen of selenium-deficient broilers. We replicated the splenic-apoptotic model in selenium-deficient broilers. In vitro, microRNA-155 oligonucleotides were transfected into lymphocytes and subsequently treated with H2O2. We observed that selenium deficiency altered the microRNA profile and decreased the expression of microRNA-155 in the broiler spleens. Tumor necrosis factor receptor superfamily member 1B was verified as a target of microRNA-155 in the splenocytes...
