Discussion

This study identifies non-coding RNAs that regulate cell cycle arrest in cardiomyocytes, suggesting roles in postnatal maturation.

Four lncRNAs and three miRNAs were identified as potential regulators of cardiomyocyte cell cycle arrest.
The study found significant downregulation of STARD4-AS1 at day 30 of differentiation, aligning with predictions from bioinformatics analysis.
Flow cytometry analysis showed increased G1-phase cardiomyocytes at day 30, indicating progression in postnatal maturation.
Further investigations are needed to thoroughly understand the functional roles of these non-coding RNAs in cardiac development.

Rezaee et al. (2025) studied this question.
