Figure Lengend Snippet: Figure 4. Hoechst staining of FaDu cells treated with compound 8e, (A) Control group; (B) 20 nM group.

Article Snippet: Then, the cells were stained with Hoechst 33,342 solution (10 μg/mL in the culture medium, Beyotime Institute of Biotechnology, Shanghai, China) at 37 ◦C in the dark for 20 min after treatment with 8e.

Article Title: Paeoniflorin Attenuates Dexamethasone-Induced Apoptosis of Osteoblast Cells and Promotes Bone Formation via Regulating AKT/mTOR/Autophagy Signaling Pathway

doi: 10.1155/2021/6623464

Figure Lengend Snippet: Effect of paeoniflorin on DEX-induced apoptosis in MC3T3-E1 cells. (a, b) The extent of apoptosis of MC3T3-E1 cells was detected by flow cytometry after Annexin V-FITC/PI double staining. The apoptotic rate was measured by flow cytometric analysis. Data are presented as the mean ± SD. ∗∗ P < 0.01 vs. control; # P < 0.05 vs. DEX. (c) MC3T3-E1 cells were stained by Hoechst to show the extent of apoptosis after interventions of DEX and paeoniflorin. (d) The expressions of osteogenic protein-Runx2 (runt-related transcription factor2) and apoptotic proteins such as Bcl-2 (B cell leukemia 2) and Bax (BCL2-associated X protein) were measured by western blot. ∗ P < 0.05, ∗∗ P < 0.01 vs. control; # P < 0.05 vs. DEX; ## P < 0.01 vs. DEX. (e) Protein levels of caspase-3 and cleaved caspase-3 were determined by western blot analysis, shown in quantitative analysis. Data are presented as the mean ± SD. ∗∗ P < 0.01 vs. control; # P < 0.05 vs. DEX.

Article Snippet: For Hoechst staining, 10 μ L Hoechst live cell staining solution (Beyotime Institute of Biotechnology) was added to the culture medium and mixed gently.
