Nature Publishing Group presents a Collection on microRNAs and cancer, which includes original Research and Review articles, as well as Research Highlights, from Nature Genetics, Nature Reviews Genetics and Nature Reviews Cancer. The collection is freely available until 30 September 2008.

MicroRNAs (miRNAs) — an abundant class of small non-protein-coding regulators of gene expression — play an important role in tumorigenesis and, depending on their targets, can function as tumour suppressors or oncogenes. Crucially, miRNA-expression profiling of human tumours has identified signatures associated with diagnosis, staging, progression, prognosis and response to treatment. The editors of the Collection summarise the content here, and the table of contents can be viewed here. On the Library page, there is a set of links to a selection of News and Views, Research Highlights, Reviews, Research Articles, Perspectives and Commentaries published by Nature Publishing group journals on microRNA and cancer, some of which are freely available to June 2008.
