Subsequently, the expression patterns of miR‐150‐5p and CXCL1 were determined with the help of RT‐qPCR and Western blot assay, which revealed that HF mice presented with suppressed miR‐150‐5p and elevated CXCL1 levels compared with the control mice (Figure 1G,H). The gene discussed is CXCL1; the disease is hydrops fetalis.
