BACKGROUND Accumulating evidence indicates that miRNAs play an important role in the development of amyotrophic lateral sclerosis (ALS). Most of previous studies on miRNA dysregulation in ALS focused on the alterative expression in ALS animal model or in limited samples from European patients with ALS. In the present study, the miRNA expression profiles were investigated in Chinese ALS patients...

Serum exosomal microRNAs (miRNAs) have received considerable attention as potential biomarkers for tumor diagnosis. Reverse transcription‑quantitative polymerase chain reaction (RT‑qPCR) is commonly used to detect miRNA expression levels in various types of cancer. One prerequisite for valid RT‑qPCR data is the correct normalization of miRNAs to stably expressed endogenous reference genes (RGs)...

BACKGROUND Non-small cell lung cancer (NSCLC) accounts for more than 85% of lung cancer cases which cause most of cancer-related deaths globally. However, the results vary largely in different studies due to different platforms and sample sizes. Here, we aim to identify the key miRNAs in the carcinogenesis of NSCLC that might be potential biomarkers for this cancer. METHODS Meta-analysis was ...

PURPOSE The aim of the present study was to assess the expression of miRNAs in the Vitreous Humor (VH) of patients with Macular Hole (MH) and Epiretinal Membrane (ERM) compared to a control group. METHODS In this prospective, comparative study, 2-ml of VH was extracted from the core of the vitreous chamber in consecutive patients who underwent standard vitrectomy for ERM and MH. RNA was extra...

microRNAs are a class of small RNAs that have been extensively studied, which involved in many biological processes and disease occurrence. The incidence intrauterine growth restriction is higher mammals, especially multiparous mammals. In this study, we found the weight longissimus dorsi growth-restricted pigs was significantly lower than normal pigs. Then, pig were used to characterize miRNA ...

Atrial fibrillation (AF) is the most common cardiac arrhythmia with a potential to cause serious complications. Mitochondria play central roles in cardiomyocyte function and have been implicated in AF pathophysiology. MicroRNA (miR) are suggested to influence both mitochondrial function and the development of AF. Yet mitochondrial function and miR expression remain largely unexplored in human a...
