感谢您的意见。Fig2A中颜色相同的点代表组内重复。试验最初每个样品重复了四次我在材料方法中增加了这个描述。根据PCAFig2A的结果我们排除了一个差异最大的值每个样本选择3个相似重复进行后续分析。Translate into English

Thank you for your feedback. In Fig.2A, points with the same color represent replicates within each group. Initially, each sample was replicated four times, and I have added this description in the Materials and Methods section. Based on the results of PCA (Fig.2A), we excluded one value with the largest difference and selected three similar replicates from each sample for further analysis.
