| Transgenic Mice Expressing A Real-Time Reporter For Cellular Camp In A Tissue-Selective And Inducible Manner |
| Cyclic AMP (cAMP) mediates the response to hormones, neurotransmitters and other molecules in practically every tissue of the body. The inventors have generated a unique transgenic mouse that is able to express an inducible fluorescent cAMP reporter in targeted cells and tissues. To achieve this, transgenic mice carrying the newly generated and unique cAMP reporter are mated with mice carrying an appropriate, tissue-specific, antibiotic-sensitive triggering mechanism in their genome. Mice tailored to a specific tissue can be readily generated. By injecting a commonly available antibiotic, researchers can then induce the synthesis of the cAMP reporter in pre-specified cells. Using this mouse model, cAMP can be examined in intact organs, tissues and cells both in vitro and in vivo. The transgenic mouse will make it possible to monitor how intracellular cAMP levels change in response to metabolites, transmitters, hormones, and drugs in real time and with high spatial resolution (i.e., single cells and even subcellular regions). |
| This mouse is an important drug discovery tool. Pharmaceutical industry scientists as well as academic researches can use this mouse to monitor responses to existing drugs and develop new ones. Additionally, this mouse could be used to test the effects of treatments affecting the brain, spinal cord, or autonomic nervous system. |
| This only mouse model available that allows responses to drugs, metabolites, transmitters, hormones, pharmaceuticals, etc. to be monitored visually in vivo. Furthermore, the response can be seen in real time with high spatial resolution. |
