Small non-coding RNAs, including microRNAs (miRNAs), endogenous small interfering RNAs (endo-siRNAs) and Piwiinteracting RNAs (piRNAs), play essential roles in mammalian development. The function and timing of expression of these three classes of small RNAs differ greatly. piRNAs are expressed and play a crucial role during male gametogenesis, whereas endo-siRNAs are essential for oocyte meiosi...

downs syndrome (ds), or trisomy 21, is the most common genetic cause of cognitive impairment and congenital heart defects in the human population. to date, the contribution of micrornas (mirnas) in ds has not been investigated. bioinformatic analyses demonstrate that human chromosome 21 (hsa21) harbors five mirna genes mir-99a, let-7c, mir-125b-2, mir-155 and mir-802. mirna expression profiling...

Background: Psoriasis is a chronic inflammatory dermatosis. The hyperproliferation and hyperkeratosis of keratinocytes key step in the pathogenesis psoriasis. Long non-coding RNAs (lncRNAs) mRNAs regulate gene expression various biological process, including function keratinocytes. This research investigated profile lncRNAs patients with psoriasis vulgaris.

Long non-coding RNAs are defined as transcripts larger than 200 nucleotides but without protein-coding potential. There is growing evidence of the important role of long non-coding RNAs in cancer initiation, development and progression. In this study, we sought to evaluate the long non-coding RNA expression profile of patients with cytogenetically normal acute myeloid leukemia (AML). RNA-sequen...

 Backgrounds: MicroRNAs (miRNAs) have crucial roles in cellular and molecular processes related to different malignancies including chronic lymphocytic leukemia (CLL). In recent years the most studies demonstrated that the expression of miR-95, alter in several diseases. Long non-coding RNAs (lncRNAs) a heterogeneous group of non-coding and regulatory RNAs. The present study investigated the as...

Non-coding RNAs have emerged as key regulators in diverse cellular processes. Y RNAs are ∼100-nucleotide-long non-coding RNAs that show high conservation in metazoans. Human Y RNAs are known to bind to the Ro60 and La proteins to form the Ro ribonucleoprotein complex. Their main biological function appears to be in mediating the initiation of chromosomal DNA replication, regulating the autoimmu...

The growing attention that non-coding RNAs have attracted in the field of cancer research in recent years is undeniable. Whether investigated as prospective therapeutic targets or prognostic indicators or diagnostic biomarkers, the clinical relevance of these molecules is starting to emerge. In addition, identification of non-coding RNAs in a plethora of body fluids has further positioned these...

MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression by binding to the 3'-UTR of their target genes, can act as oncogenes or tumor suppressors. Recently, other types of non-coding RNAs-piwiRNAs and long non-coding RNAs-have also been identified. Hodgkin lymphoma (HL) is a B cell origin disease characterized by the presence of only 1% of tumor cells, known as Hodgkin and Reed-...

Non-coding RNAs (ncRNAs) are involved in the regulation of numerous biological processes and pathways and therefore have been extensively studied in human diseases. Previous reports have shown that non-coding RNAs play a crucial role in the pathogenesis and aberrant regulation of respiratory diseases. The altered expression of microRNAs (miRNAs) and long noncoding RNAs in blood and also locally...
