Cellular Biomechanic Impairment in Cardiomyocytes Carrying the Progeria Mutation: An Atomic Force Microscopy Investigation

Abstract: Given the clinical effect of progeria syndrome, understanding the cell mechanical behavior of this pathology could benefit the patient's treatment. Progeria patients show a point mutation in the lamin A/C gene (LMNA), which could change the cell's biomechanical properties. This paper reports a mechano-dynamic analysis of a progeria mutation (c.1824 C > T, p.Gly608Gly) in neonatal rat ventricular myocytes (NRVMs) using cell indentation by atomic force microscopy to measure alterations in beating force, frequenc… Show more

“…28 The mechanical properties of myocardial cells have been found to affect substantially several important factors of cell functions, such as the shape, contraction force, rate, duration, adhesion and stiffness. [29][30][31][32] Therefore, analyzing the mechanical behaviors of cardiomyocytes affected by EGFR-TKIs is of great signicance to understand the pathogenesis and the treatment of patient. In order to provide guidance for evaluating the effects of EGFR-TKIs on myocardial cells, getinib, afatinib and osimertinib were selected and represented the three different generations of drugs, respectively.…”
