Abstract (original English)

Cell communication and competition pathways are malleable to Myocardial Infarction (MI). Key signals, transcriptive regulators, and metabolites associated with apoptotic responses such as Myc, mTOR, and p53 are important players in the myocardium. The individual state of cardiomyocytes, fibroblasts, and macrophages in the heart tissue are adaptable in times of stress. The overlapping communication pathways of Wnt/β-catenin, Notch, and c-Kit exhibit the involvement of important factors in cell competition in the myocardium. Depending on the effects of these pathways on genetic expression and signal amplification, the proliferative capacities of the previously stated cells that make up the myocardium, amplify or diminish. This creates a distinct classification of "fit" and "unfit" cells. Beyond straightforward traits, the intricate metabolite interactions between neighboring cells unveil a complex battle. Strategic manipulation of these pathways holds translational promise for rapid cardiac recovery post-trauma.
