Challenging the "chromatin hypothesis" of cardiac laminopathies with LMNA mutant iPS cells
Authors listChiara Mozzetta Francesco Saverio Tedesco
Lamins A and C are intermediate filaments that provide structural support to the nuclear envelope and regulate gene expression. In this issue, Bertero et al. (2019. J. Cell Biol. https://doi.org/10.1083/jcb.201902117) report that although lamin A/C haploinsufficient cardiomyocytes show disease-associated phenotypes, those changes cannot be explained by alterations in chromatin compartmentalization.
