Arts & Sciences Electronic Theses and Dissertations
Abnormalities in electrical impulse generation and/or propagation that affect the heartճ normal rhythm are extremely common. Clinically, cardiac arrhythmias are prevalent worldwide, yet the molecular mechanisms underlying their pathology remain largely unknown. Current treatments for arrhythmias primarily target symptoms rather than the underlying cause and these treatments have limited efficacy. The most common risk factor for developing an arrhythmia is a previous cardiac injury; however, the mechanisms underlying this are not well described. My thesis work has demonstrated that the Notch signaling pathway, which is crucial for cardiac patterning and development and is normally quiescent in adult cardiomyocytes (CMs), is …
