Study of pheonotype of the H9c2 cells derived from rat cardiac myoblasts

Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Bc. Martina Kutichová Supervisor: Doc. PharmDr. Tomáš Šimůnek, Ph.D. Supervisor - specialist: Doc. MUDr. Michaela Adamcová, Ph.D. Title of diploma thesis: Study of phenotype H9c2 cells derived from rat cardiac myoblasts The cell-based in vitro investigation represents an important and frequently employed platform in current biomedical research. In experimental cardiovascular research, enzymatically dispersed neonatal or adult cardiomyocytes from various animal species are considered as a "gold standard" for such experiments. However, besides isolated primary cultures, permanent cell lines are becoming extremely popular among cardiovascular scientists. H9c2(2-1) is the first permanent cardiomyocyte-derived cell line. Although these cells are known since the mid-seventies, there is not much information about their phenotype. This study followed the results of the shotgun proteomic analysis, which identified about 1500 proteins. The aim of this thesis was to continue with obtained proteomic results with focus on detection of specific proteins by Western blot method. H9c2 cell were studied for the presence of several muscle and/or cardiac specific proteins in both non-proliferating H9c2..
