The aim of this study was to identify circulating microRNAs (miRNAs) that could be used as biomarkers in patients at risk for or affected by AIDS-Kaposi's sarcoma (KS). Screening of 377 miRNAs was performed using low-density arrays in pooled plasma samples of 10 HIV/human herpesvirus 8 (HHV8)-infected asymptomatic and 10 AIDS-KS patients before and after successful combined antiretroviral therapy (cART). MiR-375 was identified as a potential marker of active KS, being the most down-regulated in AIDS-KS patients after cART and the most up-regulated in naïve AIDS-KS patients compared to naïve asymptomatic subjects...

Early detection of nasopharyngeal carcinoma (NPC) is of vital importance for improving prognosis and survival rates. MicroRNA (miRNA) are a class of short and non-coding RNA molecules that are capable of inhibiting the translation of mRNA of target genes. Previous studies have revealed that miRNA are involved in tumorigenesis and cancer development. The RNase-resistance of circulating miRNA have made them valuable non-invasive biomarkers, and has therefore drawn particular attention to their therapeutic potential...

Circulating microRNAs (miRNAs) are promising diagnostic markers in various types of cancers, including papillary thyroid carcinoma (PTC). However, there is sparse information reported with regards to miRNA expression in papillary thyroid microcarcinoma (PTMC) or concerning the role of a combination of miRNAs and ultrasound (US) in the diagnosis of PTMC before surgery. Therefore, we designed a study that aimed to evaluate miRNA expression levels and their potential associations with US findings and determine whether miRNAs could be used as diagnostic and prognostic biomarkers of PTMC...

BACKGROUND: A modern approach to identify biomarkers of solid cancers in tissues and body fluids is based on microRNA (miRNA) expression profiling. miRNAs are a group of approximately 3.000 short noncoding RNAs containing 18-25 nucleotides that regulate gene expression at the post-transcriptional (mRNA) level. The abilities of miRNAs to inhibit the translation or induce degradation of oncogenes and tumor suppressors indicate that they are involved in carcinogenesis. There is increasing evidence that miRNAs regulate apoptosis, cell proliferation, differentiation, and invasion...

BACKGROUND: Molecular characterization of tumors could be important for clinical management. Plasma DNA obtained noninvasively as a liquid biopsy could be widely applicable for clinical implementation in biomarker-based treatment strategies. CONTENT: Prostate cancer is a disease with variable clinical outcomes and molecular features and therefore presents multiple opportunities for biomarker-based treatment optimization. Tissue analysis may not be representative of the lethal clone in localized disease or of intrapatient, intermetastases heterogeneity; fresh tissue is often challenging to obtain by biopsy of metastasis, whereas archival samples may not represent current disease and may be of insufficient quality...

BACKGROUND: Overtreatment is a well-known clinical challenge in local prostate cancer (PCa). Although risk assessment models have contributed to a better stratification of patients with local PCa, a tailored management is still in its infancy. Over the last few decades, microRNAs (miRNAs) have shown promising results as biomarkers in PCa. The aim of this study was to investigate circulating miRNAs after management of local PCa. METHODS: The relative expression of four miRNAs (miRNA-21, -93, -125b, and miRNA-221) was assessed in plasma from 149 newly diagnosed patients with local or locally advanced PCa...

Brain injury and inflammation induces a local release of extracellular vesicles (EVs) from astrocytes carrying proteins, RNAs, and microRNAs into the circulation. When these vesicles reach the liver, they stimulate the secretion of cytokines that mobilize peripheral immune cell infiltration into the brain, which can cause secondary tissue damage and impair recovery. Recent studies suggest that suppression of EV biosynthesis through neutral sphingomyelinase 2 (nSMase2) inhibition may represent a new therapeutic strategy...

Even if anabolic androgenic steroid (AAS) abuse is clearly associated with a wide spectrum of collateral effects, adolescents and athletes frequently use a large group of synthetic derivatives of testosterone, both for aesthetic uses and for improving performance. Over the last few years, the development of MicroRNA (miRNA) technologies has become an essential part of research projects and their role as potential molecular biomarkers is being investigated by the scientific community. The circulating miRNAs detection as a diagnostic or prognostic tool for the diagnosis and treatment of several diseases is very useful, because with a minimal quantity of sample (peripheral blood), miRNAs are very sensitive...

The metastatic dissemination is a complex multistep process by which tumor cells from a primary site enter into the systemic circulation to finally spread at distant sites. Even if this mechanism is rare at the tumor level, it remains the major cause of Osteosarcoma-patients' relapse and mortality. MicroRNAs (miRNAs) have recently been described as novel epigenetics' genes' expression regulators actively implicated in cancer progression and dissemination. The understanding of their implication in the metastatic spreading could help clinicians to improve the outcome of osteosarcoma...

MicroRNAs are a class of small non-coding RNA that regulate gene expression at a post-transcriptional level. MicroRNAs have been identified in various body fluids under normal conditions and their stability as well as their dysregulation in disease has led to ongoing interest in their diagnostic and prognostic potential. Circulating microRNAs may be valuable predictors of early-life complications such as birth asphyxia or neonatal seizures but there are relatively few data on microRNA content in plasma from healthy babies...
