miRNAs are a class of endogenous, small non-protein coding RNA molecules ( 22 nucleotides) which are novel post-transcriptional regulators of gene expression. Since we have hundreds of miRNAs, the major challenge is now to understand their specific biological function. In fact the experimental evidence suggests that signaling pathways could be ideal candidates for miRNA-mediated regulation. Several studies suggest that miRNAs affect the responsiveness of cells to signaling molecules such as WNT, Notch, TGF-β and EGFR. Altered expression of particular miRNAs has been implicated in the...

Biotechnology is a recognized research area that has increasingly advanced into new technologies and modern practices raising several legal, ethical and regulatory issues. The revolutionary speed of biotech innovations has had a significant impact on the protection of the rights of the individual. Fundamental rights provide a framework within which the justification of "limitations and restrictions"" "to biotechnology innovations and research results have to be assessed. The legal regulation of scientific research and scientific investigations impact more and more directly on the freedom...

More and more conditions are now identified as having a genetic component, and controversial new genetic technologies potentially have major consequences for social relations and self-identity. How do family members respond to the information that they have a genetically transmitted disease or condition? How do they communicate (or not communicate) about their shared heritage? How do they decide who to tell and who not to tell within their family? Richly illustrated with the real experiences of individuals and families, Risky Relations is essential reading for anthropologists and...

This volume contains 29 engrossing chapters contributed by worldwide, leading research groups in the field of chemical biology. Topics include pre-biology; the establishment of the genetic code; isomerization of RNA; damage of nucleobases in RNA; the dynamic structure of nucleic acids and their analogs in DNA replication, extra- and intra-cellular transport; molecular crowding by the use of ionic liquids; new technologies enabling the modification of gene expression via editing of therapeutic genes; the use of riboswitches; the modification of mRNA cap regions; new approaches to detect...
