Abstract Objective To analyze the expression profile variation of circular RNA (circRNA) between hypoxia preconditioned human placenta chorionic mesenchymal stem cells (H-hpcMSCs) and normoxic preconditioned hpcMSCs (N-hpcMSCs). Methods Human circRNA microarray was performed to detect the difference of circRNA expression between 3 paired specimens of H-hpcMSCs and its N-hpcMSCs. The circRNA differental expression and the predicted miRNA of differentially expressed circRNA were analyzed. Results Of the 13 617 circRNAs, 12 114 circRNAs with analytical results. In H-hpcMSCs, a total of 102 circRNAs showed differentially expressed which have more than 1.5 times variation and significant difference (P < 0.05). Among them, 85 increased and change′s fold more than 1.5 times, while 17 reduced and change′s fold more than 1.5 times, a total of 27 circRNAs showed a greater than 2-fold change and all were up-regulated. Five miRNAs of each with differentially expressed circRNA were predicted according to specific base pairing. Conclusion The circRNA expression profile of H-hpcMSCs changed significantly in comparison with N-hpcMSCs, the circRNA may be associated with the hypoxia precondition.
