Hence, the derivation of cardiomyocytes from CPVT patients can provide the means to study, in the mutated myocytes, the functional changes and the underlying molecular mechanisms of CPVT, screen and develop candidate drugs on a patient-specific level, and thus advance our understanding of the disease and consequently improve its future clinical outcome. Although DADs were described in vitro Inhibitors,research,lifescience,medical and in vivo in CPVT mouse models, the demonstration that these phenomena

were responsible for arrhythmogenesis in humans was largely a Dasatinib consequence of genetic research.52 Therefore, our findings37 and those of others38,39 demonstrating the generation of DADs and triggered arrhythmias in human CPVT patient-derived Inhibitors,research,lifescience,medical cardiomyocytes are of great importance. Finally, investigating the responsiveness, to anti-arrhythmic

drugs, of CPVT-mutated cardiomyocytes from individual patients may give rise to the future application of “personalized medicine,” which is likely to reduce the morbidity and mortality of patients affected by inherited arrhythmias.

The term sociotype Inhibitors,research,lifescience,medical has been introduced to describe

the dynamic relationship of an individual with his/her social environment throughout the life trajectory.1 It is a framework for understanding how people manage life in general, and chronic disease in particular. The sociotype interacts with Rutecarpine genotype expression through, for example, mate selection, epigenesis, and metabolic programming, and with the phenotype throughout life from birth to old age. The sociotype is an explanatory framework that analyses and expands the many factors usually included in the environmental influences on a person’s life. The sociotype is constituted by individual health, relationships, and environment. Every person is thus a product of the prevailing mores and his/her “three-fold cord”—genotype, phenotype, and sociotype. Figure 1 shows these interactions. Figure 1 The relationship of the sociotype to genotypic expression and the phenotype throughout the life cycle.
