[Retracted] Berberine Attenuates IL-1<i>β</i>-Induced Damage of Nucleus Pulposus Cells <i>via</i> Activating the AMPK/mTOR/Ulk1 Pathway

<div>Effect of Berberine on ECM-related protein expression and ECM degradation in IL-1<i>β</i>-induced NP cells. (a) NP cells were treated with 1.00 <i>μ</i>M BBR, IL-1<i>β</i>, or 1.00 <i>μ</i>M BBR combined with IL-1<i>β</i>, and the mRNA level of aggrecan, collagen II, and MMP-13 was evaluated by RT-qPCR. (b) Confocal imaging of NP cells was collected by staining collagen II antibody (green). (c) Protein levels of aggrecan, collagen II, and MMP-13 were evaluated by immunoblot. Scale bars: 25 <i>μ</i>m, magnified ×400.
