Figure Lengend Snippet: COUP-TFI modifies the expression of the CXCL12 signaling axis in MCF-7 cells. (A) Characterization of the control and COUP clones. An immunofluorescence cytochemistry assay was used to detect the relative expression of HA/COUP-TFI or COUP-TFI proteins in the control (Cont.) and COUP clones. The cells were fixed and processed for immunofluorescence as described in Methods; the nuclei were stained with DAPI. (B) CXCL12 , CXCR4 , and CXCR7 mRNAs were quantified by a real-time PCR analysis from two independent MCF-7 control and COUP clones. The results were normalized to GAPDH mRNA used as an internal control. The results were expressed as the relative mRNA expression level of CXCL12 , CXCR4 , or CXCR7 . Data are the mean values ± SEM of at least three independent experiments. The asterisks indicate significant differences ( p < 0.05) between the control and COUP clones. (C) The amount of intracellular HA/COUP-TFI, COUP-TFI, CXCL12, CXCR4, and CXCR7 protein was determined from whole-cell extracts of the different MCF-7 clones and compared to total ERK. A representative western blot is shown. (D) The control and COUP clones were fixed, and an immunofluorescence cytochemistry assay was used to detect the relative expression of CXCL12, CXCR4, and CXCR7 proteins. Staining with DAPI is also presented to visualize the nucleus of the cells.

Figure Lengend Snippet: COUP-TFI modulates the chromatin structure of the CXCL12 and CXCR4 gene promoters. The FAIRE assay was performed as described in Methods. Real-time PCR was performed to monitor the enrichment of DNA corresponding to the proximal promoter of the CXCL12 (A) , the CXCR4 (B) and the CXCR7 (C) genes relative to the input chromatin from the control (Cont.) and COUP clones. The data are from triplicate samples and are representative of three separate experiments. The asterisk indicates significant differences ( p < 0.05) between the control and COUP clones.

Figure Lengend Snippet: The effect of COUP-TFI on the CXCL12/CXCR4 axis is mediated by EGF/EGFR activation. (A) The relative expression of EGF and EGFR mRNA was monitored by a real-time PCR analysis using MCF-7 control (Cont.) and COUP clones. The results were normalized against GAPDH as the internal control and are expressed as the mean EGF or EGFR mRNA/GAPDH mRNA ratio ± SEM of at least three independent experiments. The asterisks indicate significant differences ( p < 0.05) between the control and COUP clones. (B) ERK activation was examined in the MCF-7 control (Cont.) and COUP clones after a 5- or 10-min stimulation with EGF (10 −9 M) or CXCL12 (200 ng/mL). Western blots were performed using antibodies against phospho-ERK (P-ERK) and total ERK (ERK1/2); a representative western blot is presented. The importance of EGFR-specific signaling and general ERK signaling on CXCL12 (C) and CXCR4 (D) regulation was assayed by treating the cells with EGF (10 −9 M), AG1478 (25 μM), or U0126 (25 μM) for 48 h. The CXCL12 and CXCR4 relative mRNA levels were monitored by the real-time PCR analysis, normalized to GAPDH mRNA as the internal control, and were expressed as the relative mRNA expression of CXCL12 or CXCR4 . Data are the mean ± SEM of at least three independent experiments. The asterisks indicate significant differences ( p < 0.05) between the untreated and treated control clones. The pound sign indicates significant differences ( p < 0.05) between the untreated and treated COUP clones.

Figure Lengend Snippet: COUP-TFI overexpression influences cellular responses to CXCL12. (A) The relative growth of the control (Cont.) and COUP clones was assayed with or without CXCL12 treatment for 7 days. The basal and CXCL12-induced cell growth were evaluated by MTT assays (n = 6) and determined in three independent experiments. The results are expressed as the relative cell number obtained when the control cells were treated with the vehicle control. Significant differences between the unstimulated control cells and the other conditions ( p < 0.05) are indicated with an asterisk. Significant differences between stimulated control cells and stimulated COUP clones ( p < 0.05 ) are indicated with a pound sign. (B) The migratory capacity of control (Cont.) and COUP clones was analyzed. The cells were maintained in phenol red-free DMEM/2.5% dsFBS for 48 h and then seeded in phenol red-free DMEM/0.5% dsFBS in the upper chamber of a PET 8-μm pore insert. The cells were allowed to migrate for 24 h toward the phenol red-free DMEM/2.5% dsFBS medium complemented or not with CXCL12 (200 ng/mL) and AMD3100 (50 μM). (C) CXCL12 was also added to the culture medium in the upper chamber prior to migration. The results are expressed as the mean ± SEM of the relative number of migratory cells compared to the basal migration of the control cells measured in three independent experiments. The asterisks indicate significant differences ( p < 0.05) from the basal migration of the control clones. The pound sign indicates significant differences ( p < 0.05) between two conditions linked by black lines.

CXCR4 (A) , CXCR7 (B) , CXCL12 (C) , and COUP-TFI (D) mRNA expression was measured by real-time PCR in 23 normal breast tissue samples (NT), in 20 SBR grades 1 and 2, and in 19 SBR grades 3. The expression level was normalized by 18S RNA expression and analyzed with IQ5 software (Bio-Rad). The data are presented as whisker plots in which the horizontal bar represents the median, the grey boxes are the 25 th and 75 th percentiles, the vertical bar is the standard deviation, and the plus signs are the extreme points. All the Mann-Whitney tests were performed with Minitab 16 software, and the p value is indicated on the different graphs (ns denotes non-significant).
