Figure 4. NLRX1 induces selective mitochondrial fission and mitophagy to maintain adaptive mitochondrial morphology. Primary human NP cells isolated from degenerated NP tissues were prepared. (A) Co-localization analysis of mCherry and GFP in live stable mCherry-GFP-MAP1LC3B-expressing NP cells following the treatments of PBS, TBHP or Baf-A1 with NLRX1 overexpression or not, scale bar: 200 μm. (B and C) protein expressions of mitophagy indicators (MAP1LC3B-II, TOMM20, TIMM23) in primary human NP cells isolated from degenerated NP tissues following the treatments of PBS, TBHP or Baf-A1 with NLRX1 overexpression or not, as determined by western blotting. (D-F) mitochondrial morphology analysis by fluorescence microscope with MitoTracker Red CMXRos label (D and E) and transmission electron microscopy (TEM) (F) in primary human NP cells isolated from degenerated NP tissues following the treatments of PBS or TBHP with NLRX1 overexpression or not, fluorescent scale bar: 5 μm, TEM scale bar: 2 μm (upper panel), 500 nm (lower panel). (G and H) protein expressions of mitochondrial dynamics indicators (p-DNM1L, DNM1L, MFF, MFN1, MFN2, OPA1, OMA1) in primary human NP cells isolated from degenerated NP tissues following the treatments of PBS or TBHP with NLRX1 overexpression or not. (I and J) protein expressions of PINK1 and PRKN in primary human NP cells isolated from degenerated NP tissues following the treatments of PBS or TBHP with NLRX1 overexpression or not. (K) confocal analysis of MitoTracker labeling and PRKN protein with if staining in primary human NP cells isolated from degenerated NP tissues following the treatments of PBS or TBHP with NLRX1 overexpression or not, scale bar: 10 μm. Data are represented as mean ± SD.

Figure 7 Niujiaodihuang Detoxify Decoction (NDD) medicated serum improves mitochondrial function via mitochondrial homeostasis regulated by the OMA1-OPA1 pathway in LO2 cells. Western blotting was taken to determine the effect of NDD medicated serum on the expression of OMA1 and L-OPA1 (a); WB detection the interference potency of SiRNA-OPA1 (b); Western blotting was applied to examine the effect of NDD medicated serum on the expression of mitochondrial function-related proteins MFN1, MFN2, and DRP1 (c); The JC-1 kit was used to detect mitochondrial membrane potential (d); Kits were employed to measure reactive oxygen species levels (e). Data were presented as means ± standard error of mean.
