Figure Legend Snippet: (A), (B) and (C): Inhibition of the CXCL12/CXCR4 interaction by (A) the peptide analogs T22, T140, TC14012 and CTCE-9908 and the small molecules (B) AMD3100, AMD3465, AMD11070, IT1t and (C) WZ811, Me6TREN and gambogic acid. Jurkat cells were incubated with 2.9 nM CXCL12 AF647 in the presence of different concentrations of compound. Data are represented as % inhibition of maximal CXCL12 binding to CXCR4. Mean ± SEM of three or four independent experiments is shown.
Techniques Used: Inhibition, Incubation, Binding Assay
Figure Legend Snippet: Fluo-2 AM loaded cells were treated with serial dilutions of compound and subsequently stimulated with 6.25 nM CXCL12. Fluorescence changes were measured over time in all wells simultaneously. (A): The inhibitory effect of different concentrations of AMD11070 on CXCL12-induced calcium release is shown. The red and blue line represent the negative (untreated, without CXCL12 stimulation) and positive (untreated, CXCL12 stimulation) control, respectively. Calcium fluxes are represented as % of baseline ( i . e . mean relative light units in each well during a fixed time interval before CXCL12 addition). One representative experiment out of three is shown with each data point corresponding to the mean fluorescence of three to six replicates. (B), (C) and (D): Inhibitory effect of (B) T22, T140, TC14012, CTCE-9908, (C) AMD3100, AMD3465, AMD11070, IT1t, (D) WZ811, Me6TREN and gambogic acid on CXCL12-induced calcium flux. Data are represented as % inhibition of CXCL12-induced calcium mobilization relative to the positive and negative control. Mean ± SEM of three independent experiments is shown.
Techniques Used: Fluorescence, Control, Inhibition, Negative Control
Figure Legend Snippet: SUP-T1 cells were stained with a mAb targeting the N-terminus of CXCR4 (clone 1D9) and then treated with different concentrations of compound. CXCR4 internalization was induced by stimulating samples with CXCL12 at 37°C and quantified by flow cytometry. (A): Flow cytometric analysis of the negative (untreated, no CXCL12 stimulation; red histogram) and positive (untreated, CXCL12 stimulation; dark blue histogram) control and TC14012-treated samples (50 nM to 0.5 nM; light blue, green and orange histogram, respectively). (B), (C) and (D): Inhibitory effect of (B) T22, T140, TC14012, CTCE-9908, (C) AMD3100, AMD3465, AMD11070, IT1t, (D) WZ811, Me6TREN and gambogic acid on CXCR4 endocytosis. Data are represented as % of CXCR4 internalization relative to the positive and negative control. Mean ± SEM of at least two independent experiments is shown.
Techniques Used: Staining, Flow Cytometry, Control, Negative Control
Figure Legend Snippet: (A), (B) and (C): Effect of (A) T22, T140, TC14012, CTCE-9908, (B) AMD3100, AMD3465, AMD11070, IT1t, (C) WZ811, Me6TREN and gambogic acid on chemotaxis of CXCR4-positive Jurkat cells. After compound treatment, cells were allowed to migrate towards 6.25 nM CXCL12, present in the lower compartment of the insert, for two hours. The migrated cells were counted by flow cytometry. Data are represented as % inhibition of migration relative to the negative and positive control (spontaneously migrated cells and cells migrated towards CXCL12, respectively). ± SEM of two to three independent experiments, each performed in triplicate.
Techniques Used: Chemotaxis Assay, Flow Cytometry, Inhibition, Migration, Positive Control
