qRT-PCR (quantitative reverse transcription polymerase chain reaction), Western blot, and immunohistochemistry confirmed the expression of AIFM1, CCT8, HNRNPA1, KHDRBS1, and SERBP1 in patients' nucleus pulposus tissue, suggesting these genes as key targets for IDD risk assessment and drug therapy. This evidence concerns the gene HNRNPA1 and intervertebral disk degenerative disorder.
