FGFR1 and skin hemangioma: Statistical analysis showed that miR-424 was expressed at low levels in tissues with relatively high FGFR1 expression, while miR-424 exhibited a high expression level when FGFR1 was expressed at a relatively low level (Fig. 1M), suggesting that the miR-424 expression in infantile skin hemangioma tissues was negatively correlated with FGFR1.
