Advances in Cancer Drug Targets is an e-book series that brings together recent expert reviews published on the subject with a focus on strategies for synthesizing and isolating organic compounds and elucidating the structure and nature of DNA. The contents of this volume include reviews on mediating or inhibiting different signaling pathways such as WNT signaling and MTOR as well as novel drug targets for tumor control such as neutrophil elastase and estrogen sulfatase. These reviews provide updates on new ways to treat a variety of cancers. The reviews presented in this series are written by experts in pharmaceutical sciences and molecular biology. These reviews have been carefully selected to present development of new approaches to anti-cancer therapy and anti-cancer drug development. The reference work serves to give readers a brief yet comprehensive glance at current theory and practice behind employing chemical compounds for tackling tumor suppression, DNA site specific drug targeting and the inhibition of enzymes involved in growth control pathways. This e-book volume will be of special interest to molecular biologists and pharmaceutical scientists.
