Our Innovation, Your Research sigma-aldrich.com By David H. Hall, Albert Einstein College of Medicine, New York; Zeynep F. Altun, Albert Einstein College of Medicine, New York erived from the acclaimed online “WormAtlas,” C. elegans Atlas is a Dlarge-format, full-color atlas of the hermaphroditic form of the model organism C. elegans, known affectionately as “the worm” by workers in the field. Prepared by the editors of the Wormatlas Consortium, David H. Hall and Zeynep F. Altun, this book combines explanatory text with copious, labeled, color illustrations and electron micrographs of the major body systems of C. elegans. Also included are electron microscopy cross sections of the worm. This laboratory reference is essential for the working worm biologist, at the bench and at the microscope, and provides a superb companion to the C. elegans II monograph. It is also a valuable tool for investigators in the fields of developmental biology, neurobiology, reproductive biology, gene expression, and molecular biology. 2008, 348 pp., illus., appendix, index Concealed wire binding $125 ISBN 978-087969715-0 Hardcover $175 ISBN 978-087969794-5 CONTENTS 1.

MicroRNAs and Cancer Research Figure 1 MicroRNAs are short 19–25-nucleotide noncoding RNA molecules that can regulate the expression of genes involved in many biological processes, including development, differentiation and apoptosis1. Approximately half of all human microRNA genes are localized in fragile chromosomal regions Advertisement feature that are associated with various human cancers2. Additionally, several microRNAs, referred to as ‘oncomirs’, can have a direct role in oncogenesis by acting as tumor suppressors or oncogenes3. Several recent studies have associated microRNA signatures with tumor classifi cation, as well as prognosis, diagnosis and treatment response in cancer 4-6. The importance of microRNAs for future cancer diagnostics and treatments and as drug targets is clear, but many technical challenges associated with analyzing microRNAs have slowed their progress into the development programs and clinical applications.

Samples consisted of paired samples from eleven patients. Both downregulated (blue) and accurate and sensitive tools for microRNA analysis. Locked upregulated (red) microRNAs were identifi ed in breast cancer. The Nucleic Acids (LNA™) are a class of high-affi nity nucleic microRNA numbers do not refer to specifi c microRNAs. acid analogs. Insertion of LNA™ into DNA oligonucleotides increases the binding affi nity of that oligonucleotide to its complementary DNA or RNA target.

It has become apparent, however, that the small discrimination that enables optimal differentiation between size of microRNAs makes them particularly challenging closely related members of the same microRNA family.
