The authors claim that other members of their lab attempted to repeat the experiments in this study several times and found that the activation ability of snail on circ-znf652 was significantly lower than reported, indicating that this regulation loop does not exist. The authors' incorrect experimental method and lack of reasonable control, coupled with the lack of experimental experience of the first author, led to the mistakes and mean the results cannot be relied upon. In order not to mislead other scientists, they requested to retract their manuscript. The Editor-in-Chief has approved this retraction.

The authors apologise to the readership of the journal for these errors.

作者声称，他们实验室的其他成员多次尝试重复本研究中的实验，发现 snail 对 circ-znf652 的激活能力明显低于报道的水平，表明该调节回路不存在。作者不正确的实验方法和缺乏合理的控制，加上第一作者缺乏实验经验，导致了错误，导致结果不可靠。为了不误导其他科学家，他们要求撤回手稿。主编已批准撤回。

作者为这些错误向期刊的读者道歉。
