If you are looking to learn more about cell-signaling mechanisms involved in cancer, keep up with the latest news in cancer research, and follow clinical trials, then might I suggest the BioOncology HD app by Genentech. This sleekly designed app covers these things and more, such as a list of useful web links, as well as information about upcoming conferences and funding sources. A nice feature of the clinical trials resource is that it covers both Genentech and non-Genentech trials (though the default display is Genentech only). The “research” section of the app contains very nice animations depicting signaling pathways involved in cancer, such as apoptosis, angiogenesis, and the Hedgehog pathway. The “explore” feature is not too exciting—it only allows one to zoom in to the image—but the video animations make up for this shortcoming.
