Abstract
Abstract
We show that zinc finger imprinted 3 (Zim3), when used as Zim3-KRAB-dCas9 effector in interference CRISPR, without any guide RNAs, paradoxically up-regulates key cardiac ion channel genes in human-induced pluripotent stem-cell-derived cardiomyocytes (iPSC-CMs), responsible for healthy resting membrane potential, repolarization of the action potential, and electrical transmission of signals. These were found to yield expected functional enhancements consistent with a more mature iPSC-CM phenotype, with potentially desirable properties.
