Attention deficit hyperactivity disorder (ADHD) is a neuropsychiatric disorder whose aetiology still remains elusive. Nevertheless, evidence supports a high genetic contribution that interacts with environmental factors, also known to modulate epigenetic processes. These epigenetic modulators are a class of non-coding RNAs, microRNAs (miRNAs), known as post-transcriptional regulators, which have emerged as prospective players in neuropsychiatric disorders since they play a role in brain development, synapse formation, and the fine-tuning of genes underlying synaptic and memory formation...

Shedding of nano-sized bilayered extracellular vesicles and extracellular vesicle-mediated intercellular communication are evolutionarily conserved biological processes. Communication between cells and the environment is an essential process in living organisms and dysregulation of intercellular communication leads to various diseases. Thus, systematic studies on extracellular vesicles, also known as exosomes, microvesicles, and outer membrane vesicles, are critical for a deeper understanding of intercellular communication networks that are crucial for decoding the exact causes of various difficult-to-cure diseases...

Since it is impossible to recognize malignancy at fine needle aspiration (FNA) cytology in indeterminate thyroid nodules, surgery is recommended for all of them. However, cancer rate at final histology is <30%. Many different test-methods have been proposed to increase diagnostic accuracy in such lesions, including Galectin-3-ICC (GAL-3-ICC), BRAF mutation analysis (BRAF), Gene Expression Classifier (GEC) alone and GEC+BRAF, mutation/fusion (M/F) panel, alone, M/F panel+miRNA GEC, and M/F panel by next generation sequencing (NGS), FDG-PET/CT, MIBI-Scan and TSHR mRNA blood assay...

MicroRNAs (miRNAs) are a class of noncoding RNAs and have emerged as critical regulators of gene expression. Some miRNAs play important roles in regulating the function of the immune system and are involved in the pathogenesis of autoimmune diseases. Recent studies suggested that microRNA-22-3p (miR-22-3p) was able to regulate the function of several types of immune cells and may be involved in the development of autoimmune diseases. We systematically reviewed relevant literatures to provide a comprehensive review of the possible roles of miR-22-3p in autoimmune diseases...

Thyroid cancer (TC) is the most common endocrine malignancy, with an incidence continuing to grow every year. Although thyroid cancer as a whole is generally indolent and relatively easy to treat, some subtypes carry a higher rate of metastasis and cancer-related mortality. A growing number of studies have focused on the dysregulation of miRNAs in TC. However, differences in methods make comparison of gene profiling data difficult. A meta-analysis of published studies comparing miRNA expression data of invasive thyroid carcinoma with paired non-invasive tumors or normal tissues was performed by searching the literature for "invasion", "thyroid cancer", and "miRNA"...

Epigenomics is one of the leading frontiers of postgenomics medicine. The challenges and prospects ahead in epigenomics are related not merely to technology innovation and clinical implementation but also to science communication. In this context, microRNAs (miRNAs) are an important part of the epigenomic regulatory machinery. As the number of publications reporting miRNA-target interactions (MTIs) is growing rapidly, there is an urgent need to standardize reporting. This study reports (1) an analysis of the published literature and databases reporting validated MTIs, and for the first time to the best of our knowledge (2) suggests a solution as a way forward, the minimum information required for MTI standard reporting...

Hypoxia, a common feature of tumor microenvironment, is known to accelerate tumor development and growth by promoting the formation of a neoplastic environment. Recent studies have provided a wealth of evidence that miRNAs are significant members of the adaptive response to low oxygen in tumors. miR-210 is one of the hypoxia-induced miRNAs, which has been reported extensively in cancer researches. However, there is no systematic discussion about the role of miR-210 in gastrointestinal cancer. We conducted a literature research in database including PubMed, Elsevier Science Direct and Medline before 16 September 2016, in order to collect articles of miR-210 in gastrointestinal cancer...

PURPOSE: Glucocorticoids (GCs) are of wide usage in the clinical treatment of lymphoblastic malignancies such as acute lymphoblastic leukemia. However, individually distinctive responsiveness to the GC therapy may attenuate their clinical efficacy, and more reliable predictor for GC resistance is still eagerly needed. Recent studies indicate that microRNAs (miRNAs), which demonstrate regulatory functions targeting mRNAs during the post-transcription, involved in the regulation of GCs sensitivity through several mechanisms, especially adjusting the magnitude of GC receptors (GRs), which mediates the cellular effects of GCs and plays a pivotal role in GCs sensitivity, inspiring that special miRNAs pattern could serve as the biomarkers to predict GC sensitivity and bring forth potential strategies for overcoming drug resistance...

RAS belongs to the super family of small G proteins and plays crucial roles in signal transduction from membrane receptors in the cell. Mutations of K-RAS oncogene lead to an accumulation of GTP-bound proteins that maintains an active conformation. In the pancreatic ductal adenocarcinoma (PDAC), one of the most deadly cancers in occidental countries, mutations of the K-RAS oncogene are nearly systematic (>90%). Moreover, K-RAS mutation is the earliest genetic alteration occurring during pancreatic carcinogenetic sequence...

BACKGROUND: Colorectal cancer (CRC) is common and associated with significant mortality. Current screening methods for CRC lack patient compliance. microRNAs (miRNAs), identified in body fluids, are negative regulators of gene expression and are dysregulated in many cancers, including CRC. This paper summarises studies identifying blood-based miRNAs dysregulated in CRC compared with healthy controls in an attempt to evaluate their use as a screening tool for the diagnosis of CRC. METHODS: A search of electronic databases (PubMed and EMBASE) and grey literature was performed between January 2002 and April 2016...

Malignant mesothelioma (MM) is an insidious, lethal asbestos-related cancer that is poorly responsive to current treatments. Specific and sensitive biomarkers providing early MM diagnosis in exposed subjects, who are at high-risk of developing it, are sorely needed. MicroRNAs (miRNAs) are endogenous, non-coding, small RNAs with a well-established diagnostic role in cancer and pollution exposure. In a recent systematic review and qualitative meta-analysis followed by a functional investigation, we examined all the available data on the miRNA biomarkers involved in asbestos exposure and MM pathways...

MicroRNAs (miRNAs) are a group of small RNAs that control gene expression in all aspects of eukaryotic life, primarily through RNA silencing mechanisms. The purpose of the present review is to introduce key miRNAs involved in periodontal homeostasis, summarize the mechanisms by which they affect downstream genes and tissues, and provide an introduction into the therapeutic potential of periodontal miRNAs. In general, miRNAs function synergistically to fine-tune the regulation of biological processes and to remove expression noise rather than by causing drastic changes in expression levels...
