Article Title: AXL Overexpression in Tumor-Derived Endothelial Cells Promotes Vessel Metastasis in Patients With Hepatocellular Carcinoma

doi: 10.3389/fonc.2021.650963

Figure Lengend Snippet: AXL/SOX2/DKK-1 axis in HUVECs promotes HCC metastasis. (A) DKK-1 and CCL14 secretion was significantly downregulated in CM from HUVEC-AXL-KD compared with that from HUVEC-AXL-NC, as detected with a human cytokine antibody array. (B) DKK-1 and CCL14 expression was markedly upregulated in the CM of HUVECs overexpressing AXL (CCL14: p < 0.001; DKK-1: p = 0.003) compared with the CM of HUVEC-AXL-NC, as detected by ELISA assay. (C) AXL siRNA downregulated DKK-1 and CCL14 secretion in the CM of HUVEC-AXL-NC and HUVEC-AXL-OE cells (CCL14: p < 0.001 and p < 0.001; DKK-1: p < 0.001 and p < 0.001). (D) DKK1 siRNA (MHCC-97L: p < 0.001 and p < 0.001; HCC-LM3: p <0.001 and p < 0.001), but not CCL14 siRNA (MHCC-97L: p = 0.126 and p = 0.711; HCC-LM3: p = 0.901 and p = 0.694) could attenuate the effect of the CM from HUVEC-AXL-NC and HUVEC-AXL-OE cells on the migration of HCC-LM3 cells and MHCC-97L cells. (E) SOX2 mRNA expression was significantly increased in HUVEC-AXL-OE cells and decreased in HUVEC-AXL-KD cells compared with HUVEC-AXL-NC cells (HUVEC-AXL-KD: p < 0.001, HUVEC-AXL-OE: p < 0.001). (F) AXL overexpression could significantly increase SOX2 and DKK-1 protein expression in HUVEC-AXL-OE cells compared with HUVEC-AXL-NC cells, and SOX2 siRNA inhibited SOX2 and DKK-1 protein expression in HUVEC-AXL-OE and HUVEC-AXL-NC cells.

Article Snippet: The protein concentrations of CCL14 and DKK-1 in the supernatants were also measured using an enzyme-linked immunosorbent assay (ELISA) kit (CCL14: EK1123 Boster, Wuhan, China; DKK-1: EK0867 Boster, Wuhan, China) according to the manufacturer’s instructions.

Figure Lengend Snippet: PD-MSC transplantation induces Wnt signaling and angiogene-sis in CCl 4 -injured rats. Angiogenic (A) and Wnt signaling (B) factors were detected by Western blotting. Localization and expression of VEGF and β -catenin visualized using immunofluorescence (C). ×630, Scale bars; 20 μ m. Positive correlations were found between CRP and β -catenin (D) also, between β -catenin and VEGF (E). NTX and TTX refer to the non-transplanted group and the PD-MSC-transplanted group, respec-tively.

Figure Lengend Snippet: PD-MSCs promote the expression of CRP and proliferation of hepatocytes through Wnt signaling. Expression of CRP was analyzed by qRT-PCR (A) and ELISA (B) after CCl 4 treatment and co-culture with PD-MSCs. Immunofluorescence staining shows the localization and expression of BrdU and β -catenin in rat hepatocytes treated with CCl 4 and co-cultured with PD-MSCs (C). ×400, Scale bars; 20 μ m. BrdU- or β -ca-tenin-(D) positive rat hepatocytes were quantified after immunofluore-scence staining. Protein levels of HNF1 α , and CyclinD1 were detected by western blotting in rat hepatocytes treated with CCl 4 and co-cultured with PD-MSCs (E). Intensity of HNF1 α (F) and Cyclin D1 (G) protein bands was calculated. Tripli-cated data are represented as the mean±SD. *, p<0.05.
