QRT-PCR confirmation results of the four lncRNAs and two mRNAs. The four lncRNAs lincRNA-SLC20A1-1, RP11-296A18.3, KB-1683C8.1, lincRNA-BTG2 and two mRNAs CASP8, FAF1 were chosen for the validation of the gene chip results using qRT-PCR. The height of the columns in the figure represents the lncRNA expression level relative to glyceraldehyde-3-phosphate dehydrogenase; the bars represent standard deviation. Normal represents the normal disc group; Degenerated represents the degenerated disc group.*P <0.05 versus the normal group.
