Book Description
This SpringerBrief gives the latest research on the role of miRNAs in breast cancer metastasis. MicroRNAs (miRNAs) are recently described small endogenous noncoding RNAs implicated in the posttranscriptional control of gene expression. These tiny molecules are involved in developmental, physiologic phenomenon as well as pathologic processes including cancers. In fact, miRNAs have emerged as critical regulators of cancer progression, invasion and metastasis. This is mainly because a single miRNA can affect several downstream genes and signaling pathways with oncogenic or tumor suppressor actions depending on the target genes affected. Due to this multimodal downstream signaling effects, these small endogenous molecules hold great promise in metastasis prevention and treatment. Modulating the activity of miRNAs can provide opportunities for novel cancer interventions. Targeting miRNAs could become a novel prognostic and therapeutic strategy to prevent the future development of metastasis. Thus, miRNAs could also serve as a potential targets for anti-metastatic therapy. The book explores how the expression of miRNAs in the primary tumor could be silenced using antagomirs (chemically modified anti-miRNA oligonucleotides), which could prevent the development of metastasis; whereas once metastasis develops then it could be treated with miRNA mimics for inducing its expression for the treatment. Therefore, development of miRNA-based prophylactic therapies could serve as precision and personalized medicine against future development of metastasis of breast and other cancers.

Book Description
MicroRNAs have recently emerged as key regulators of gene expression during development and are frequently misexpressed in human disease states, in particular cancer. These 22-nucleotide-long transcripts act to promote or repress cell proliferation, migration and apoptosis during development, all of which are processes that go awry in cancer. Thus, microRNAs have the ability to behave like oncogenes or tumor suppressors. In addition, their small size and molecular properties make them amenable as targets and therapeutics in cancer treatment. This book goes into detail on how microRNAs represent a paradigm shift in thinking about gene regulation during development and disease, and provide the oncologist with a potentially powerful new battery of agents to diagnose and treat cancer.

Book Description
Metastases are responsible for>90% of human cancer deaths; yet, our knowledge regarding the molecular regulation of metastasis remains fragmentary. MicroRNAs are short RNAs that suppress their targets post-transcriptionally, leading to modulation of diverse biological processes. MicroRNAs are well suited to regulate metastasis due to their capacity to concomitantly inhibit numerous target genes. We have identified a microRNA, miR-31, whose levels correlated inversely with metastatic recurrence in human breast cancer patients. Expression of miR-31 in otherwise-aggressive breast tumor cells impeded metastasis. We deployed a novel microRNA sponge strategy to stably inhibit miR-31; this allowed otherwise-non-aggressive breast cancer cells to metastasize. These phenotypes were achieved via pleiotropic modulation of a cohort of clinically relevant metastasis-promoting genes, which were over represented among the>200 mRNAs predicted to be direct targets of miR-31. In fact, we discovered that miR-31-evoked concurrent regulation of three such effectors - integrin alpha5, radixin, and RhoA - was sufficient to explain this microRNA's impacts on metastasis. Together, these findings provide insights into metastasis that may prove useful in the diagnosis and/or treatment of breast cancer.

Book Description
This book provides an update on the latest development in the field of microRNAs in cancer research with an emphasis on translational research. Since the early 2000s, microRNAs have been recognized as important and ubiquitous regulators of gene expression. Soon it became evident that their deregulation can cause human diseases including cancer. This book focuses on the emerging opportunities for the application of microRNA research in clinical practice. In this context, computer models are presented that can help to identify novel biomarkers, e.g. in circulating microRNAs, and tools that can help to design microRNA-based therapeutic interventions. Other chapters evaluate the role of microRNAs in immunotherapy, immune responses and drug resistance. Covering key topics on microRNAs in cancer research this book is a valuable resource for both emerging and established microRNA researchers who want to explore the potential of microRNAs as therapeutic targets or co-adjuvants in cancer therapies.

Book Description
In these studies, the microRNA miR-31 was identified as a potent inhibitor of breast cancer metastasis. miR-31 expression levels were inversely associated with the propensity to develop metastatic disease in human breast cancer patients. Additionally, various functional analysis revealed that miR-31 expression was both necessary and sufficient to impede breast cancer metastasis. These effects did not involve confounding influences on primary tumor development; instead, miR-31 exerted its anti-metastatic activities by impinging upon at least three distinct steps of the invasion-metastasis cascade: local invasion, one or more early post intravasation events, and metastatic colonization. At a mechanistic level, miR-31 impaired metastasis via the pleiotropic suppression of a cohort of target genes that otherwise operate to promote metastasis, including integrin a5, radixin, and RhoA. Significantly, the concomitant re-expression of integrin a5, radixin, and RhoA sufficed to override the full spectrum of miR-31'7s anti-metastatic activities. Moreover, the concurrent short hairpin RNA-conferred knockdown of endogenous integrin a5, radixin, and RhoA levels closely phenocopied the known consequences of ectopic miR-31 expression on metastasis. Integrin a5, radixin, and RhoA were found to act during at least partially unique steps of the invasion-metastasis cascade downstream of miR-31. Notably, the temporally controlled re-activation of miR-31 in already-established metastases elicited metastatic regression. These anti-metastatic therapeutic responses were attributable to the capacity of acutely re-expressed miR-31 to induce both cell cycle arrest and apoptosis; such effects arose specifically within the context of the foreign microenvironment present at a metastatic locus. When taken together, these findings provide mechanistic insights concerning the regulation of breast cancer metastasis and suggest that miR-31 may represent a clinically useful prognostic biomarker and/or therapeutic target in certain aggressive human carcinomas. In addition, a novel experimental system for the unbiased identification of metastasisrelevant genes was described. The utility of this system was demonstrated in an initial proof-of-concept screen, which implicated RhoJ as a previously unappreciated modulator of cell motility. Collectively, these observations imply that the single-cell clone-based screening methodology outlined herein may represent a generally useful means by which to enumerate novel regulators of various metastasis-relevant processes.

Book Description
Cancer is one of the leading causes of death in most countries and its consequences result in huge economic, social and psychological burden. Breast cancer is the most frequently diagnosed cancer type and the leading cause of cancer death among females. In this book, we discussed gene expression and DNA abnormalities including methylation in breast cancer. A recent important topic, roles of miRNAs and their potential use in cancer therapy have been discussed in this cancer type as well. Bioinformatics is very important part of recent human genome developments and data mining and thus this topic has also been added for the readers. It is hoped that this book will contribute to development of novel diagnostic as well as therapeutic approaches, which lead to cure of breast cancer.
