Overview of Gene Research
4632428C04Rik, also named cardiomyocyte hypertrophic associated inhibitory RNA (CHAIR), is a long noncoding RNA (lncRNA). It has a crucial cardioprotective function, likely through an epigenetic mechanism. It may be involved in the regulatory pathways related to heart development and heart failure [1].
In mouse models, loss-of-function experiments of 4632428C04Rik (KO) showed that while it has no effect on normal hearts, under stress, it leads to accelerated heart function decline, increased hypertrophy, and exacerbated heart failure. In contrast, restoring its expression can rescue the heart from hypertrophy and failure. During heart failure, DNMT3A is recruited to the CHAIR promoter to suppress its expression, and CHAIR interacts with DNMT3A to inhibit its DNA-binding activity [1].
In conclusion, 4632428C04Rik plays a significant cardioprotective role. The KO mouse models have revealed its importance in heart failure, suggesting that it could be a potential target for treating heart failure and related pathological conditions [1].
