Article Title: ADSCs stimulated by resistin promote breast cancer cell malignancy via CXCL5 in a breast cancer coculture model.

doi: 10.1038/s41598-022-19290-6

Figure Lengend Snippet: Figure 3. Secreted CXCL5 in the conditioned medium of the co-culture model with resistin-stimulated ADSCs promoted malignant behaviors of breast cancer cells. The isolated ADSCs were treated with resistin at 0 and 100 ng/ml (R0 and R100, respectively) for 48 h, followed by co-culture with MDA-MB-231 cells in the transwell model for another 72 h before the analyses in (A,B,F,G). (A) The conditioned medium from the co-culture of R-ADSCs (R100) or control ADSCs (R0) with MDA-MB-231 cells was collected and analyzed by cytokine/ chemokine proteome array. A total of 102 proteins were detected with duplicates for each protein. The position of CXCL5 on the array was highlighted. (B) Secreted protein level of CXCL5 in the conditioned medium from the co-culture of R-ADSCs (R100) or control ADSCs (R0) with MDA-MB-231 cells was analyzed by ELISA. (C) MDA-MB-231 cells treated with recombinant CXCL5 (0, 20, and 40 ng/ml) for 48 h were collected and evaluated by cell migration assay. (D) MDA-MB-231 cells treated with recombinant CXCL5 (0, 20, and 40 ng/ml) for 48 h were collected and evaluated by cell invasion assay. (E) MDA-MB-231 cells treated with recombinant CXCL5 (0, 20, and 40 ng/ml) for 48 h were collected and analyzed for the protein expression of mesenchymal marker Slug and cancer stemness marker Oct4 by Western blot. The original blot images in (A) and (E) were available in Supplementary Information. (F,G) CXCL5 neutralizing antibody was added ( +) or omitted (–) during the co-culture of R-ADSCs (R100) or control ADSCs (R0) with MDA-MB-231 cells. After the co-culture, MDA-MB-231 cells were collected and evaluated by cell migration assay in (F) and cell invasion assay in (G). Data were obtained from three independent experiments and presented as mean ± SEM. Statistical difference was determined by t-test comparing R100 group versus their corresponding R0 group as control, or comparing recombinant CXCL5 treatment group (20 and 40 ng/ml) versus recombinant CXCL5 control group (0 ng/ml). *p < 0.05; **p < 0.01; ***p < 0.001.

Article Title: ADSCs stimulated by resistin promote breast cancer cell malignancy via CXCL5 in a breast cancer coculture model.

Figure Lengend Snippet: Figure 5. Enhanced breast tumor growth and protein expression of CXCL5, Slug, and ERK phosphorylation in mice via xenograft of breast cancer cells after co-culture with resistin-stimulated ADSCs. The isolated ADSCs were treated with resistin at 0 and 50 ng/ml (denoted as R0 and R50, respectively) for 48 h, followed by co-culture with MDA-MB-231 cells in the transwell model for another 72 h. After the co-culture, MDA-MB-231 cells were collected and injected into the fourth mammary fat pads of female NOD/SCID mice for the following analyses. (A) The tumor volume, calculated by (width2 × length)/2, was measured weekly after palpable tumor mass was formed. (B) Upon sacrifice of the mice on week eight, the weight of individual tumor mass was measured. (C) The body weight of the mice was measured weekly. (D) The tumor mass was collected after sacrifice of the mice on week eight, and analyzed for CXCL5, Slug, and phospho-ERK1/2 protein expression by immunohistochemistry (IHC). The quantitative IHC scores were manually evaluated and calculated by multiplying the categorized percentage of stained cells (0, 0–24%; 1, 25‑49%; 2, 50‑74%; 3, 75‑100%) by the categorized intensity of staining (0, negative; 1, weak; 2, moderate; 3, strong). Data were obtained from three to six mice in each group and presented as mean ± SEM or box plots. Statistical difference was determined by t-test comparing R50 group versus R0 group as control. *p < 0.05; **p < 0.01; ***p < 0.001.

Figure Lengend Snippet: Figure 6. Correlation analysis for the protein expression of resistin, CXCL5, and ERK phosphorylation in the tumor and serum specimens from breast cancer patients. (A) Representative images of immunohistochemistry (IHC) staining for resistin, CXCL5, and phospho-ERK1/2 expression in breast tumor sections from breast cancer patients. (B–D) The quantitative IHC scores were evaluated by HistoQuest software, followed by Pearson correlation (r) analysis between resistin and CXCL5 in (B) (n = 96), resistin and phospho-ERK1/2 in (C) (n = 45), and CXCL5 and phospho-ERK1/2 in (D) (n = 45). (E) The serum levels of resistin and CXCL5 in breast cancer patients were determined by ELISA, followed by Pearson correlation (r) analysis (n = 120). The mean ± SD of resistin and CXCL5 was 31.4 ± 15.4 ng/ml and 707.9 ± 293.4 pg/ml, respectively. (F) Schematic summary of the current study. Our preclinical and clinical data together suggest that CXCL5 may be secreted by resistin-stimulated ADSCs in the breast tumor microenvironment, promoting breast cancer cell malignancy via the participation of ERK pathway and epithelial-to-mesenchymal transition.
