The mammalian target of rapamycin complex 1 (mTORC1) activity is paramount in the regulation of electrical activities in the brain and the heart. In the brain, the tumor suppressor gene TSC2 encodes the protein product tuberin that interacts with hamartin to form a heterodimer Tuberous Sclerosis Complex (TSC) that regulates mTORC1. When TSC2 is disrupted, mTORC1 activity becomes dysregulated resulting in abnormal electrical activities in the brain manifesting in the form of epileptic seizures. In the heart, mTORC1 activity is triggered by a sustained increase in hemodynamic pressure causing the heart to electrically remodel. A likely candidate serving as the …

Cardiac dysfunction is one of the largest obstacles to effective cancer treatment. Not only do a growing number of cancer patients have significant cardiovascular risk factors at the time of diagnosis, but a number of targeted therapies can themselves cause cardiac dysfunction. These newer treatment options are also increasingly effective, placing a growing emphasis on post-cancer quality of life. In some instances, a patient may outlive his or her cancer only to succumb to heart failure in as little as five years. One such targeted therapy is the small molecular receptor tyrosine kinase sunitinib. Sunitinib was developed in the early …
