Submitted references The sphingosine 1-phosphate receptor 2 is shed in exosomes from breast cancer cells and is N-terminally processed to a short constitutively active form that promotes extracellular signal regulated kinase activation and DNA synthesis in fibroblasts.

- Figure 3 Identification of S1P 2 in exosomes shed from MDA-MB-231 breast cancer cells (A) Western blot with anti-GFP or anti-mCherry antibodies showing the over-expression of GFP-hsp70 and mCherry-tgs101 in vector (V) or plasmid transfected MDA-MB-231 cells for 24 or 48 h. (B) Western blot with anti-GFP or anti-mCherry or anti-HA antibodies showing the presence of GFP-hsp70, mCherry-tsg101 or HA tagged S1P 2 (Mr = 40 kDa) in transfected MDA-MB-231 cell lysate (CL) and acid precipitates (PPT) of CM. (C) Western blot with anti-hsp70, anti-CD63 and anti-S1P 2 antibodies showing the presence of GFP-hsp70, CD63 or S1P 2 in MDA-MB-231 cell lysates (CL) and isolated exosomes (EXO) from CM. (D) Immunofluorescence image of MDA-MB-231 cells stained with anti-CD63/TRITC (red) secondary and anti-S1P 2 /FITC (green) secondary antibodies showing co-localisation (yellow) of CD63 and S1P 2 in large vesicles typical of MVBs. (E) Electron micrograph of immunogold staining with anti-CD63 [attached to secondary goat anti-mouse IgG-immune-gold particles (15 nm)] and anti-S1P 2 antibodies [attached to secondary goat anti-rabbit IgG-immune-gold particles (10 nm)] in exosomes isolated from CM of MDA-MB-231 cells. Control represents exosomes that have not been incubated with primary antibody. Results are representative of 3 independent experiments.
