Abstract: MicroRNA profiles transition from normal breast to ductal carcinoma in situ and transition to invasive ductal carcinoma (IDC) and methods of use thereof are described. Methods of diagnosis and prognosis using microRNA signatures to differentiate invasive from in situ carcinoma are described. Also described is the use of microRNA expression for predicting overall survival and time to metastasis.

Abstract: It is disclosed herein that miR-221 and miR-222 down-regulate PTEN and TIMP3 tumor suppressors, resulting in TRAIL resistance. The present invention provides research, diagnostic, and therapeutic tools and methods related to this discovery. Diagnostics, prognostics and treatments for human hepatocellular cancer and non-small cell lung carcinoma having a TRAIL resistance are particularly described herein.

Abstract: Described herein are methods of diagnosing a cancer and/or myeloproliferative disorder using microRNAs. Also described are compositions and methods related to cancers and myeloproliferative disorders.

Abstract: Provided herein are methods and compositions for the diagnosis, prognosis and treatment of a cancer associated disorder using the Fhit gene.

Abstract: The present invention provides materials and methods related to modulation of mismatch repair and genomic stability by miR-155.

Abstract: Disclosed are compositions, such as nucleic acids, vectors, cells, animal models and the like, useful to reduce tumor growth, cancer cell migration and various other cancer pathologies associated with EGFR (epidermal growth factor receptor) and MET (the receptor tyrosine kinase for hepatocyte growth factors) dyregulation, particularly in non-small cell lung carcinoma.

Abstract: Provided are methods and compositions for the treatment of cancers associated with overexpression of a BCL2 gene and/or gene product in a subject, and methods and compositions for the improvement of anti-cancer therapy, such as chemotherapy and radiation therapy. Also provided are methods for determining the efficacy of a cancer therapy in a subject, methods for diagnosing cancer, methods for assessing patient prognosis, and methods for inducing apoptosis of a cell.

Abstract: The present invention provides materials and methods related to the discovery that tumor secreted miR-21 and miR-29a can function by binding as ligands to receptors of the Tolllike receptor family, murine TLR7 and human TLR8, in immune cells, triggering a TLR-mediated prometastatic inflammatory response, which leads to tumor growth and metastasis. Thus, by acting as paracrine agonists of TLRs, secreted miRNAs are key regulators of the tumor microenvironment. This mechanism of action of miRNAs is important in the tumor-immune system communication, in tumor growth and spread, and in cancer treatment.

Abstract: Described herein is a pharmaceutical composition for treating a subject having a cancer and/or myeloproliferative disorder associated with overexpression of a HOXA1 gene product where an effective amount of at least one miR-10a gene product or an isolated variant or biologically-active fragment thereof is administered to the subject sufficient to decrease expression of the HOXA1 gene product in the subject.

Abstract: Methods and compositions for the diagnosis, prognosis and/or treatment of ovarian cancer are disclosed.

Abstract: MicroRNA genes are highly associated with chromosomal features involved in the etiology of different cancers. The perturbations in the genomic structure or chromosomal architecture of a cell caused by these cancer-associated chromosomal features can affect the expression of the miR gene(s) located in close proximity to that chromosomal feature. Evaluation of miR gene expression can therefore be used to indicate the presence of a cancer-causing chromosomal lesion in a subject. As the change in miR gene expression level caused by a cancer-associated chromosomal feature may also contribute to cancerigenesis, a given cancer can be treated by restoring the level of miR gene expression to normal. microRNA expression profiling can be used to diagnose cancer and predict whether a particular cancer is associated with an adverse prognosis. The identification of specific mutations associated with genomic regions that harbor miR genes in CLL patients provides a means for diagnosing CLL and possibly other cancers.
