[Retracted] Transcriptional Profiling Uncovers Biologically Significant RNAs and Regulatory Networks in Nucleus Pulposus from Intervertebral Disc Degeneration Patients

Figure 1

PCA and Pearson’s correlation analysis. (a) PCA results for samples of circRNA expression profiles in the GSE67566 dataset. (b) PCA results for samples of mRNA and lncRNA expression profiles in the GSE56081 dataset. (c) PCA results for samples of miRNA expression profiles in the GSE63492 dataset. Blue is indicative of control samples and yellow is indicative of IVDD samples. Each point represents a sample. Sample correlation results in the (d) GSE67566, (e) GSE56081, and (f) GSE63492 datasets. (g) Sample correlation results in the GSE63492 dataset after excluding the GSM1551029 sample. The more the color tends to be redder, the stronger the correlation; on the contrary, the more the color tends to be greener, the weaker the correlation.
