Abstract
I MicroRNAs (miRNAs) are an abundant class of small non-protein-coding RNAs that function as negative gene regulators. They regulate diverse biological processes, and bioinformatic data indicates that each miRNA can control hundreds of gene targets, underscoring the potential influence of miRNAs on almost every genetic pathway. Recent evidence has shown that miRNA mutations or mis-expression correlate with various human cancers and indicates that miRNAs can function as tumour suppressors and oncogenes. miRNAs have been shown to repress the expression of important cancer-related genes and might prove useful in the diagnosis and treatment of cancer.

The functional significance of miR-1 and miR-133a in renal cell carcinoma

TL;DR: The data indicate that up-regulation of the oncogenic TAGLN2 was due to down- regulation of tumour-suppressive miR-1 and miR -133a in human RCC.

MicroRNAs: role in cardiovascular biology and disease

TL;DR: A growing body of exciting evidence suggests that miRNAs are important regulators of cardiovascular cell differentiation, growth, proliferation and apoptosis and may represent a new layer of regulators for cardiovascular biology and a novel class of therapeutic targets for cardiovascular diseases.

MiR-100 regulates cell differentiation and survival by targeting RBSP3, a phosphatase-like tumor suppressor in acute myeloid leukemia

TL;DR: A new pathway that miR-100 regulates G1/S transition and S-phase entry and blocks the terminal differentiation by targeting RBSP3, which partly in turn modulates the cell cycle effectors pRB/E2F1 in AML is revealed.

Post-transcriptional control of DGCR8 expression by the Microprocessor

TL;DR: It is demonstrated that a hairpin, localized in the 5' untranslated region (5'UTR) of DGCR8 mRNA, is cleaved by the Microprocessor and confers Microprocessor-dependent repression of a luciferase reporter gene in vivo, uncovering a novel feedback loop that regulates DG CR8 levels.

microRNAs: a new emerging class of players for disease diagnostics and gene therapy.

TL;DR: Early detection of cancers and delivery miRNAs and/or anti‐miRNAs for miRNA gene therapy and the potential toxicity effect of mi RNA gene therapy are discussed.

MicroRNAs: Genomics, Biogenesis, Mechanism, and Function

TL;DR: Although they escaped notice until relatively recently, miRNAs comprise one of the more abundant classes of gene regulatory molecules in multicellular organisms and likely influence the output of many protein-coding genes.

The C. elegans heterochronic gene lin-4 encodes small RNAs with antisense complementarity to lin-14

TL;DR: Two small lin-4 transcripts of approximately 22 and 61 nt were identified in C. elegans and found to contain sequences complementary to a repeated sequence element in the 3' untranslated region (UTR) of lin-14 mRNA, suggesting that lin- 4 regulates lin- 14 translation via an antisense RNA-RNA interaction.

MicroRNA expression profiles classify human cancers

TL;DR: A new, bead-based flow cytometric miRNA expression profiling method is used to present a systematic expression analysis of 217 mammalian miRNAs from 334 samples, including multiple human cancers, and finds the miRNA profiles are surprisingly informative, reflecting the developmental lineage and differentiation state of the tumours.

Prediction of Mammalian MicroRNA Targets

TL;DR: The predicted regulatory targets of mammalian miRNAs were enriched for genes involved in transcriptional regulation but also encompassed an unexpectedly broad range of other functions.

The nuclear RNase III Drosha initiates microRNA processing

TL;DR: The two RNase III proteins, Drosha and Dicer, may collaborate in the stepwise processing of miRNAs, and have key roles in miRNA-mediated gene regulation in processes such as development and differentiation.
