TLDR
MiRNA-expression profiling of human tumours has identified signatures associated with diagnosis, staging, progression, prognosis and response to treatment and has been exploited to identify miRNA genes that might represent downstream targets of activated oncogenic pathways, or that target protein-coding genes involved in cancer.Abstract:
MicroRNA (miRNA ) alterations are involved in the initiation and progression of human cancer. The causes of the widespread differential expression of miRNA genes in malignant compared with normal cells can be explained by the location of these genes in cancer-associated genomic regions, by epigenetic mechanisms and by alterations in the miRNA processing machinery. MiRNA-expression profiling of human tumours has identified signatures associated with diagnosis, staging, progression, prognosis and response to treatment. In addition, profiling has been exploited to identify miRNA genes that might represent downstream targets of activated oncogenic pathways, or that target protein- coding genes involved in cancer.read more

Tumour invasion and metastasis initiated by microRNA-10b in breast cancer
TL;DR: It is shown that miR-10b is highly expressed in metastatic breast cancer cells and positively regulates cell migration and invasion, and the workings of an undescribed regulatory pathway, in which a pleiotropic transcription factor induces expression of a specific microRNA, which suppresses its direct target and in turn activates another pro-metastatic gene, leading to tumour cell invasion and metastasis.

MicroRNAs in cancer.
TL;DR: In this paper, the effects of miRNA dysregulation in the cellular pathways that lead to the progressive conversion of normal cells into cancer cells and the potential to develop new molecular miRNA-targeted therapies are discussed.

TL;DR: It is shown that mice deficient for bic/microRNA-155 are immunodeficient and display increased lung airway remodeling, and suggests that bic-micro RNA-155 plays a key role in the homeostasis and function of the immune system.

MicroRNA biogenesis pathways in cancer
Shuibin Lin,Richard I. Gregory +1 more
TL;DR: Global miRNA depletion caused by genetic and epigenetic alterations in components of the miRNA biogenesis machinery is oncogenic, highlighting the importance of miRNA dysregulation in cancer.

TL;DR: The utility of systemically administered LNA-antimiRs in exploring miRNA function in rodents and primates is demonstrated, and the potential of these compounds as a new class of therapeutics for disease-associated miRNAs is supported.

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 functions of animal microRNAs
TL;DR: Evidence is mounting that animal miRNAs are more numerous, and their regulatory impact more pervasive, than was previously suspected.

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.

Oncomirs — microRNAs with a role in cancer
TL;DR: 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.
