miR-155 plays a crucial role in proinflammatory activation. This study was carried out to assess the association of abnormal expression of miR-155 in peripheral blood of patients with Rheumatoid arthritis with the expression of TNF-α and IL-1β. Release of TNF-α and IL-1β, and expression of miR-155 were determined in RA peripheral blood or peripheral blood macrophages, followed by correlation an...
(3) first described a syndrome, commonly referred to as "writhing", which was induced in rodents by the intraperitoneal injection of various chemical agents. Collier et al. (4) have recently reported experiments on the abilities of various sub stances, including some occurring in tissues and causing pain in man, to induce abdominal construction in mice. Many investigators have described the non...
Chronic lymphocytic leukemia (CLL) is a slowly developing progression-prone disease. MicroRNAs miR-155 and miR-150 are small inhibitors of gene expression in B-cells that were previously connected to the pathogenesis of CLL. We herein evaluated relationship of miR-155/miR-150 network with clinical and routine laboratory parameters of the CLL patient cohort utilizing multivariate analyses and fo...
MicroRNAs have been reported to be regulated in different ways in a variety of liver diseases. As a key modulator of cellular function in both innate and adaptive immunity, the role of miR-155 in chronic hepatitis B virus infection remains largely unknown. Here, we investigated the expression and function of miR-155 in chronic hepatitis B (CHB) patients. It was found that miR-155 expression in ...
The purpose of this study was to explore the functional role and mechanism of miR-155 in the development of renal cell carcinoma (RCC). miR-155 expression was quantified in renal cancers, matched adjacent non‑tumor tissues and renal cell lines using quantitative real-time PCR (RT-PCR). Cell proliferation, apoptosis and migratory activity were meas...
OBJECTIVE This study was to screen for the miRNAs differently expressed in peripheral blood mononuclear cells (PBMC) of RA, to further identify the expression of miR-155 in RA PBMC and fibroblast-like synoviocytes (FLS), and to evaluate the function of miR-155 in RA-FLS. METHODS Microarray was used to screen for differentially expressed miRNAs in RA PBMC. miR-155 expression in PBMC and FLS of...
MicroRNA155 plays an important role in many solid malignancies. Expression and function of miR-155 in laryngeal carcinoma have not been fully understood. This study aims to investigate the expression and function of miR-155 in laryngeal squamous cell carcinoma (LSCC), the relationship between miR-155 and its downstream target suppressor of cytokine signaling 1 (SOCS1)-STAT3 pathway, and the rel...
Abnormal levels of microRNA (miR)-155, which regulate inflammation and immune responses, have been demonstrated in the colonic mucosa of patients with inflammatory bowel diseases (IBD), although its role in disease pathophysiology is unknown. We investigated the role of miR-155 in the acquisition and maintenance of an activated phenotype by intestinal myofibroblasts (IMF), a key cell population...
OBJECTIVE Epstein-Barr virus (EBV)-encoded latent membrane protein (LMP1) can drive aberrant expression of miR-155 in nasopharyngeal carcinoma (NPC). In this study, we investigated the regulation of miR-155 expression over UBQLN1 and studied their effects on radio-sensitivity of NPC. MATERIALS AND METHODS MiR-155, LMP1 and ubiquilin-1 expression were measured in 40 cases of NPC cases. The reg...
MicroRNA-155 (miR-155) plays pleiotropic roles in the biology of normal and malignant B lymphocytes, including the modulation of the transforming growth factor β (TGF-β) pathway via the targeting of SMAD5. However, the extent of the miR-155-mediated disruption of the TGF-β1/SMAD5 axis remains to be elucidated. To address this issue, we used the miR-155 knockout (KO) mouse and diffuse large B-ce...
