Deficiency of MIF Accentuates Overloaded Compression-Induced Nucleus Pulposus Cell Oxidative Damage via Depressing Mitophagy

<div>MIF-KO exacerbated oxidative stress-induced senescence of the NP cell that suffered overloaded compression: (a) after MIF-KO and high-compression loading treatment, the cell senescence degree of the NP cells was analyzed by SA-<i>β</i>-Gal staining (100x). (b) Statistic analysis of the SA-<i>β</i>-Gal-positive rate of the NP cells. (c) After MIF-KO and high-compression loading treatment, the ROS content of the NP cells was measured by flow cytometry following DCFH-DA staining. (d) Statistic analysis of the ROS content of the NP cells. (e) Western blotting analysis of the expression levels of MIF, oxidative stress biomarker NT, and senescence-associated markers (P53, P21, and P16) of the NP cells. (f) Statistic analysis of the western blots of the biomarkers. <span class="nowrap"><svg height="10.7395pt" id="M27" style="vertical-align:-0.6370001pt" version="1.1" viewbox="-0.0498162 -10.1025
