PPARG and intervertebral disk degenerative disorder: The effect of miR-96-5p on the apoptosis of HNPCs in IDD via PPARγ was next explored and revealed the percentage of apoptosis decreased in the IDD cell model when miR-96-5p was inhibited (P < 0.05), while downregulation of PPARγ apparently restored this (Fig. 7A, B, P < 0.05).
