Inverse Agonist of Retinoid-Related Orphan Receptor-Alpha Prevents Apoptosis and Degeneration in Nucleus Pulposus Cells via Upregulation of YAP

SR3335 treatment decreased the nucleus pulposus ECM catabolism upon TNF-α treatment. The NP cells were pretreated with 1 μM of SR3335 2 h before 10 ng/ml TNF-α treatment. (a) The mRNA level of COL2A1, ACAN, MMP13, and ADAMTS4 was assayed by real-time PCR. Data are expressed as . , , and compared with the TNF-α treated group. (b) The protein level of COL2A1, MMP13, and ADAMTS4 was assayed by western blot and quantification.
