TNFAIP6 and intervertebral disk degenerative disorder: Their analysis reveiled six key regulators (Tumor Necrosis Factor (TNF) Alpha Induced Protein 6 (TNFAIP6), Chitinase-3-like protein 1 (CHI3L1), Keratin 19 (KRT19), Dermatopontin (DPT), Collagen Type VI Alpha 2 (COL6A2) and Collagen Type XI Alpha 2 (COL11A2)) with potential functional roles in the IDD process, and they identified two regulators already reported (KRT19, COL6A2) as important IDD markers in independent studies.
