Fig. 1. Leptin-directed migration of human chondrosarcoma cells involves upregulation of <t>avb3</t> integrins. JJ012 or SW1353 cells were incubated with various concentrations of leptin, and in vitro migration activities measured with the Transwell after 24 h (A and B). JJ012 cells were incubated with leptin for 24 h, and the cell surface avb3 <t>integrin</t> was determined using flow cytometry (C). Cells were incubated with leptin for 24 h, and the mRNA levels of av and b3 integrin was determined using qPCR (D and E). Cells were pretreated with avb3 monoclonal antibody (3 and 10 lg/ml), cyclic <t>RGD</t> (100 nM) or cyclic RAD (100 nM) for 30 min followed by stimulation with leptin. The in vitro migration activity was measured after 24 h (F). Total RNA were extracted from normal cartilage (lines 1–2), primary chondrocyte (lines 3–4), chondrosarcoma patients (lines 5–6) or from chondrosarcoma cell lines (SW1353 and JJ012) and subjected to qPCR analysis for av and b3 integrin (G).

The expression was **P<.001, ***P<.05. (c) The expression of integrin β3 in Jurkat(ctrl), sh-NC and sh-ITGB3 cells detected by Western blot. (d) The expression of integrin β3 in MOLT-4 (ctrl), sh-NC and sh-ITGB3 cells detected by Western blot. The expression of β-actin was used as internal control. (e) The migratory cell counts of Jurkat (ctrl), sh-NC and sh-ITGB3 cells in transwell assays. (f) The column graph of migratory cell counts of Jurkat, BC and shITGB3 cells. ***P<.001. (g) The migratory cell counts of MOLT-4 (ctrl), sh-NC and sh-ITGB3 cells in transwell assays. (h) The column graph of migratory cell counts of MOLT-4 (ctrl), sh-NC and sh-ITGB3 cells. ***P<.001.

Integrin αV not integrin α2b interact with integrin β3 to regulate the migration of T-ALL cells. (a) The transwell assays for T-ALL cell lines, Jurkat and Molt-4, treated with solution control (ctrl), anti-integrin αvβ3 antibodies (anti-itgαvβ3) and anti-integrin α2bβ3 antibodies (anti- itgα2bβ3), respectively. (b, c) The statistical comparison of migrated T-ALL cell count (B: Jurkat, C: Molt-4) between three groups in transwell assays in (A). ***P<.001. (d) Western blot for the immunoprecipitation of α chain integrin interact with integrin β3. IgG and input represent the negative and positive control, respectively.
