Fig. 2. ETV2 induces HIF-1α stabilization and nuclear accumulation by transcriptional inhibition of PHD2 and ERK1/2 phosphorylation (A) KEGG functional enrichment analysis of RNA sequence (B) A heatmap displays genes associated with osteogenesis and HIF-1 signaling (C, D) The protein and mRNA expression of HIF-1α and PHDs following ETV2 overexpression (E) Schematic of putative ETV2 binding elements on PHD2 promoter region (F) Dual luciferase reporter gene assay of ETV2 and PHD2 (G) Cytoplasmic HIF-1α, total and phosphorylated ERK1/2, and intracellular HIF-1α expression post ETV2 overexpression (H) Representative immunofluorescent images of intracellular phosphorylated ERK1/2. The Cy3 channel fluorescence represents lentiviral transfection. Scale bar: 50 μm (I) Representative immunofluorescent images of intranuclear HIF-1α. The Cy3 channel fluorescence represents lentiviral transfection. The orange arrows indicate the fluorescence of HIF-1α in the nucleus, while the white arrows point to the absence of HIF-1α fluorescence in the nucleus. Scale bar: 50 μm (NS, no significant difference, NC, negative control; OE, overexpression. Data are presented as the mean of >3 independent experiments ±SD. *P < 0.05, **P < 0.01, and ***P < 0.001).

FIGURE 4: The histological examination at the time points corresponding to the MRI scan. The histologically stained (?200) sections of H&E, Ki67 and TUNEL at 24 hours, VEGF at 1 hour, and EGLN1 at 0 hour after treatment (a). The positive staining rate (%) of Ki67 (b) and TUNEL (c) and the mean IOD of VEGF (d) and EGLN1 (e) staining of the four experimental groups at different time points. * indicates a significant difference between groups at the same time point. Group 1: normal saline, group 2:CuS@GOD NPs, group 3: CuS NPs + laser and group 4: CuS@GOD NPs + laser.
