lncMYH7b KD causes significant effects on sarcomere organization in hiPS-CMs.A, representative images showing the three phenotypes of α-actinin staining we scored in hiPS-CMs. The “organized” category was broken down into two subphenotypes: organized sarcomeres and presarcomeres that have been shown to transition to fully organized sarcomeres in hiPS-CMs (36). This is in comparison to the disorganized phenotype, where there is no discernible organization of alpha-actinin. B, quantification of the change in α-actinin phenotype upon lncMYH7b knockdown. There is a significant decrease in the percentage of cells with α-actinin organization with MYH7b ASO treatment. Cells from three wells from two independent differentiations were scored.
