Introduction Polychlorinated biphenyls (PCBs), organic lipophilic pollutants that accumulate through diet and increase with age, have been associated polycystic ovary syndrome (PCOS) shown to affect microRNA (miRNA) expression. This work aimed determine if PCBs were circulating miRNAs whether there any correlations serum PCB/miRNA levels hormonal changes. Methods 29 non-obese PCOS healthy contr...

AIMS To identify molecular characteristics to hepatitis C virus (HCV)-associated diffuse large B-cell lymphoma (DLBCL) through a comprehensive miRNAs expression profiling. METHODS In this study, miRNA profiles were obtained from 37 patients with DLBCLs and 60 patients with reactive lymph nodes, equally distributed according to HCV presence. Germinal centres, from reactive lymph nodes were use...

Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have obtained excellent therapeutic effects against non-small cell lung cancer (NSCLC) harboring activating EGFR mutations. However, some patients have exhibited primary resistance which becomes a major obstacle in effective treatment of NSCLC. The mechanisms of EGFR-TKIs resistance involved are still poorly understood. M...

it has been well documented that preeclampsia (pe) has a common etiological background, but little is known about its linkage at the molecular level.non- coding rnas are critical posttranscriptional regulators ofgene expression.  this study was performed to determine whether peis associated with alterations in placental non-codingrnas expression. microrna(mir)-155-5p and long non-coding rna (ln...

The degradation of cruciate ligaments is frequently observed in degenerative joint diseases, such as osteo-arthritis (OA). The present study aimed to identify the differentially expressed microRNAs (miRNAs or miRs) in knee anterior cruciate ligament (ACL) tissues derived from patients with OA and in health subjects (non-OA). By using Affymetrix miRNA 4.0 microarrays, a total of 22 miRNAs (inclu...

Follicular dendritic cells (FDC) are important stromal cells within the B-cell follicles and germinal centres (GC) of secondary lymphoid tissues. FDC trap and retain native antigens on their surfaces in the form of immune complexes that they display to B cells, in order to select those cells with the highest antigen affinity. MicroRNAs are short, non-coding RNAs that are approximately 18-25 nuc...

Abstract Circulating microRNA (miRNA), a non-coding RNA molecule, is the potential biomarker for bone and mineral metabolism. Primary hyperparathyroidism (PHPT) one of leading causes secondary osteoporosis. After parathyroidectomy, BMD improves as parathyroid hormone (PTH) decreases in patients with PHPT but degree recovery vary greatly among patients. Biomarkers which are able to predict posto...

Sleep deprivation was previously reported to alter microRNA (miRNA) levels in the brain; however, the direct effects of any miRNA on sleep have only been described recently. We determined miRNA 138 (miR-138), miRNA let-7b (let-7b), and miRNA 125a-5p (miR-125a) levels in different brain areas at the transitions between light and dark. In addition, we examined the extent to which inhibiting these...
