Unbalanced tumor necrosis factor (TNF)-α production is associated with pathogenesis of a variety of human diseases. However, the molecular pathways maintaining TNF-α homeostasis remain elusive. Here, we report that NF-κB/p65-DICER-miRs axis negatively regulates TNF-α production. We demonstrated that NF-κB bound to DICER promoter and transcriptionally regulated DICER expression. In addition, the...
Background Macrophages play an important role in regulating the course of spinal tuberculosis within bone microenvironment. This study aimed to investigate differential expression miRNA macrophage-derived exosomes tuberculosis-infected microenvironment, identify miRNAs that hold potential as diagnostic markers and therapeutic targets. Methods We established cohorts for tuberculosis, collected m...
BACKGROUND The aim of this study was to investigate the diagnostic and prognostic value of microRNA (miRNA)-21, miRNA-23a, and miRNA-125b in Burkitt lymphoma (BL) in children. MATERIAL AND METHODS We recruited 41 children with BL for the case group, 56 children with lymph node inflammation for the positive control group, and 60 healthy children for the negative control group. Real-time fluoresc...
A majority of early colorectal cancers (CRCs) with submucosal invasion undergo surgical operation, despite a very low incidence of lymph node metastasis. Our study aimed to identify microRNAs (miRNAs) specifically responsible for lymph node metastasis in submucosal CRCs. MicroRNA microarray analysis revealed that miR-100 and miR-125b expression levels were significantly lower in CRC tissues wit...
Most chromosomal translocations in myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) involve oncogenes that are either up-regulated or form part of new chimeric genes. The t(2;11)(p21;q23) translocation has been cloned in 19 cases of MDS and AML. In addition to this, we have shown that this translocation is associated with a strong up-regulation of miR-125b (from 6- to 90-fold). ...
To investigate the correlation of miR-125a/b expression with acute exacerbations of chronic obstructive pulmonary disease (AECOPD) patients and inflammatory cytokines.Eighty-seven AECOPD patients, 93 stable chronic obstructive pulmonary disease (COPD) patients and 100 health volunteers (HCs) were recruited. Plasma samples were collected from AECOPD patients at the day 1, day 7, day 14, and day ...
Cardiovascular diseases and cancers are the leading causes of morbidity and mortality in the world. MicroRNAs (miRNAs) are short non-coding RNAs that primarily repress target mRNAs. Here, miR-24, miR-125b, miR-195, and miR-214 were selected as representative cardio-miRs that are upregulated in human heart failure. To bridge the gap between miRNA studies in cardiology and oncology, the targets a...
Previous findings suggest that 17beta-estradiol (estradiol) has a suppressive effect on TNF-alpha, but the mechanism by which estradiol regulates TNF-alpha expression in primary human macrophages is unknown. In this article, we demonstrate that pretreatment of human macrophages with estradiol attenuates LPS-induced TNF-alpha expression through the suppression of NF-kappaB activation. Furthermor...
28 29 We have shown that microRNAs (miRNAs) are necessary for renin cell specification and kidney 30 vascular development. Here, we used a screening strategy involving microarray and in silico analyses, 31 along with in situ hybridization and in vitro functional assays to identify miRNAs important for renin cell 32 identity. Microarray studies using vascular smooth muscle cells (SMCs) of the re...
Huntington's disease (HD) is caused by the expansion of N-terminal polymorphic poly Q stretch of the protein huntingtin (HTT). Deregulated microRNAs and loss of function of transcription factors recruited to mutant HTT aggregates could cause characteristic transcriptional deregulation associated with HD. We observed earlier that expressions of miR-125b, miR-146a and miR-150 are decreased in STH...
