For example, circFTO and circCSPP1 competitively bind to miR-148a and miR-10a, enhancing the expression of BMP7 to promote the proliferation of lakeal papillae cells [21]; circRNA-1967 upregulates the expression of LEF1 by adsorbing miR-93-3p and regulates the proliferation and differentiation of HF stem cells in cashmere goats [22]. This evidence concerns the gene LEF1 and hydrops fetalis.
