Then, by analyzing GeneFriends and an extensive RNA‐seq dataset of 112 heart tissue,[33] a significant correlation (p < 0.01)  was revealed in possible between the transcriptional expression levels of Foxo6os and MYBPC3 (Figure S3P, Table S4, Supporting Information), which suggests that Foxo6os may interact with MYBPC3 in the regulation of HF progression. This evidence concerns the gene MYBPC3 and hydrops fetalis.
