Formerly, the ceRNA pattern in CH was widely seen in other reports.[28, 34, 35] Herein, we provided new data to confirm the competition between SNHG14 and PCDH17 for miR‐322‐5p and miR‐384‐5p in CH, uncovering the ceRNA network in which SNHG14 served as an endogenous sponge for miR‐322‐5p and miR‐384‐5p to up‐regulate PCDH17. This evidence concerns the gene PCDH17 and cyclic hematopoiesis.
