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… 
MicroRNA: A signature for cancer progression.
MicroRNAs as biomarkers for the diagnosis and prognosis of human cancer
An overview of the use of microRNAs as diagnostic and prognostic tools in cancer is provided and the useof miRNA expression as biomarker for disease activity is focused on.
MicroRNA biogenesis pathways in cancer
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.
MicroRNAs as biomarkers and therapeutic drugs in human cancer
The aberrant expression of miRNAs in human cancer is introduced, and the potential of these mi RNAs as biomarkers and targets/molecules for molecular therapy is discussed.
MicroRNA involvement in the pathogenesis and management of breast cancer
Deregulation of miRNA expression profiles is thought to be implicated in the pathogenesis of many human cancers including breast tumours, which makes miRNAs important targets for developing a novel molecular classification of breast cancer and opening avenues for more individualised treatment strategies for patients with breast cancer.

The role of miRNAs in the pathogenesis of cancer as well as miRNA-profiling studies performed in human malignancies are examined, and implications for the diagnosis and treatment of cancer patients are discussed.
Dysregulation of MicroRNAs in cancer
The key functions of miRNAs in cancer, especially those affecting tumor metastasis and drug resistance are summarized and the mechanisms leading to dysregulation of miRNA dysregulation are discussed.

Because malignant cells show dependence on the dysregulated expression of miRNA genes, which in turn control or are controlled by the dysregulation of multiple protein-coding oncogenes or tumour suppressor genes, these small RNAs provide important opportunities for the development of future miRNA-based therapies.
MicroRNAs in Development and Progression of Breast Cancer
Current knowledge about the involvement of miRNAs in breast cancer and their potential as diagnostic, prognostic, and therapeutic tools is reviewed.

The emerging role of microRNAs (miRNAs) in the epigenetic regulation of many cellular processes has become recognized in both basic research and translational medicine as an important way that gene


MicroRNA-cancer connection: the beginning of a new tale.
It is proposed that alterations in miRNA genes play a critical role in the pathophysiology of many, perhaps all, human cancers.
Oncomirs — microRNAs with a role in cancer
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.
MicroRNA gene expression deregulation in human breast cancer.
It is shown that, compared with normal breast tissue, miRNAs are also aberrantly expressed in human breast cancer, and the overall miRNA expression could clearly separate normal versus cancer tissues, with the most significantly deregulated mi RNAs being mir-125b, mir-145, mir -21, and mir-155.
MicroRNA expression profiles classify human cancers
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.
Sequence variations of microRNAs in human cancer: alterations in predicted secondary structure do not affect processing.
Genetic variants in miRNA precursors are common in cancer cells but are unlikely to have physiologic significance, despite pri-miRNAs having dramatic changes in the predicted secondary folding structure flanking putative cleavage sites, processing and miRNA maturation were not affected in vivo.

The results indicate that miRNAs are extensively involved in cancer pathogenesis of solid tumors and support their function as either dominant or recessive cancer genes.
Extensive modulation of a set of microRNAs in primary glioblastoma.
Extensive post-transcriptional regulation of microRNAs and its implications for cancer.
An analysis of gene expression in primary tumors indicates that the widespread down-regulation of miRNAs observed in cancer is due to a failure at the Drosha processing step, and this work shows that a large fraction of miRNA genes are regulated post-transcriptionally.
Comprehensive analysis of microRNA expression patterns in hepatocellular carcinoma and non-tumorous tissues
Analysis of miRNA expression profiles in hepatocellular carcinoma and adjacent non-tumorous tissue specimens may help clarify the molecular mechanisms involved in the progression of liver disease, potentially serving as a diagnostic tool of HCC.
Involvement of human micro-RNA in growth and response to chemotherapy in human cholangiocarcinoma cell lines.
Altered in miRNA expression contribute to tumor growth and response to chemotherapy, and Aberrantly expressed miRNA or their targets will provide mechanistic insight and therapeutic targets for cholangiocarcinoma.
