Analyses of microRNA (miRNA) expression signatures obtained by RNA sequencing revealed that some passenger miRNAs (miR-144-5p, miR-145-3p, miR-149-3p, miR-150-3p, and miR-199a-3p) acted as anti-tumor miRNAs in several types of cancer cells. The involvement of passenger strands in the pathogenesis of human cancer is a novel concept. Based on the miRNA signature of bladder cancer (BC) obtained by RNA sequencing, we focused on both strands of the miR-223-duplex (miR-223-5p and miR-223-3p) and investigated their functional significance in BC cells...

Macrophage polarization plays a crucial role in regulating myocardial inflammation and injuries of coxsackievirus B3 (CVB3)-induced viral myocarditis (VM). It has been reported that miR-223 is a potent regulator of inflammatory responses that involved in macrophage polarization. However, the functional roles of miR-223 in CVB3-induced VM still remain unknown. Here, we found that miR-223 expression was significantly down-regulated in heart tissues and heart-infiltrating macrophages of CVB3-infected mice. Up-regulation of miR-223 in vivo protected the mice against CVB3-induced myocardial injuries characterized by the increased body weight and survival, enhanced left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS), relieved inflammation, depressed creatine kinase-MB (CK-MB), lactate dehydrogenase (LDH) and aspartate transaminase (AST) levels, reduced production of interferon (IFN)-γ, interleukin (IL)-6 as well as increased IL-10...

Prostate cancer (PCa) is one of the most common malignant cancers in male and docetaxel is commonly used as an effective chemotherapeutic drug for PCa patients. However, docetaxel resistance inhibits the therapeutic effect of this agent, thus investigating the mechanism of chemoresistance to docetaxel of PCa may help to improve the prognosis of PCa patients. In our present study, we found that miR-223-3p was up-regulated in PCa cell lines (C4-2, LNCap, PC3, DU-145). Transfection with miR-223-3p inhibitor increased chemo-sensitivity to docetaxel and cell apoptosis rate in PCa cells compared with docetaxel + miR-223-3p mock group, especially in DU-145 cells which were more resistant to docetaxel...

Atopic dermatitis (AD) is one of the most prevalent skin diseases around the world. Excessive histamine plays a critical role as an inflammatory factor in the pathogenesis of AD. Deregulated microRNAs (miRNAs) were involved in atopic dermatitis by targeting various genes. MiR-223 had been reported to play a vital role in hematopoiesis. In this study, we identified upregulated miR-223 in the whole blood cells of a large group of AD patients. What's more, we found for the first time that one of the major histamine degradation enzymes, histamine-N-methyltransferase (HNMT), was increased in AD patients and AD model mice...

Context: WNT signaling is fundamental to bone health and its aberrant activation leads to skeletal pathologies. A heterozygous missense mutation p.C218G in WNT1, a key WNT pathway ligand, leads to severe early-onset and progressive osteoporosis with multiple peripheral and spinal fractures. Despite the severe skeletal manifestations, conventional bone turnover markers are normal in mutation-positive patients. Objective: This study sought to explore the circulating miRNA pattern in patients with impaired WNT signaling...

MicroRNA-223 is known as a myeloid-enriched anti-inflammatory microRNA that is dysregulated in numerous inflammatory conditions. Here, we report that neutrophilic inflammation (wound response) is augmented in miR-223-deficient zebrafish, due primarily to elevated activation of the canonical nuclear factor κB (NF-κB) pathway. NF-κB over-activation is restricted to the basal layer of the surface epithelium, although miR-223 is detected throughout the epithelium and in phagocytes. Not only phagocytes but also epithelial cells are involved in miR-223-mediated regulation of neutrophils' wound response and NF-κB activation...

Bovine milk is rich in exosomes, which contain abundant miRNAs and play important roles in the regulation of neonatal growth and development of adaptive immunity. Here, we analyzed miRNA expression profiles of bovine milk exosomes from three healthy and three mastitic cows, and then six miRNA libraries were constructed. Interestingly, we detected no scRNAs and few snRNAs in milk exosomes; this result indicated a potential preference for RNA packaging in milk exosomes. A total of 492 known and 980 novel exosomal miRNAs were detected, and the 10 most expressed miRNAs in the six samples accounted for 80-90% of total miRNA-associated reads...
