Figure Lengend Snippet: NRK (A and B), MCF 10A (C and D), MDA-MB-231 (E and F), and MCF7 (G and H) cells were left untreated ( Control ) or treated with 5 μg/ml BFA for 60 min ( BFA ). Cells were fixed, permeabilized, and immunolabeled with rabbit polyclonal antibody to GOLPH3, mouse monoclonal antibody to GM130, and either sheep antibody to TGN38 (A and B) or sheep antibody to TGN46 (C to H). Secondary antibodies were Alexa-594-conjugated donkey anti-rabbit IgG (red channel), Alexa-488-conjugated donkey anti-mouse IgG (green channel), and Alexa-647-conjugated donkey anti-sheep IgG (blue channel). Stained cells were examined by fluorescence microscopy. Merging red, green, and blue channels generated the fourth image on each row; yellow indicates overlapping localization of the red and green channels, cyan indicates overlapping localization of the green and blue channels, magenta indicates overlapping localization of the red and blue channels, and white indicates overlapping localization of all three channels. Insets show 1.7x magnifications. Bar, 10 μm.

Figure Lengend Snippet: (A-C) MCF 10A (A), MDA-MB-231 (B), and MCF7 (C) cells transiently expressing GFP-GOLPH3 were held in a microscope stage at 37°C and examined by fluorescence microscopy. The time after initiation of imaging is shown in the bottom right corner of each panel in minutes:seconds. Images are representative of 15–20 videos of up to 200 seconds of recording. In B, filled arrows indicate a vesicular structure moving from the Golgi to the periphery of the cell. In C, filled arrows indicate a vesicular structure moving from the periphery of the cell to the Golgi area, and filled arrowheads indicate a tubular structure elongating from the Golgi. Empty arrows and empty arrowheads indicate the initial position of mobile structures. Bars, 5 μm. (D-F) The number of tubule-vesicular structures moving centrifugally (D), the number of tubular structures elongating from the Golgi (E), or the number of tubule-vesicular structures moving centripetally (F), were quantified from videos corresponding to 180 seconds of imaging. Bar represents the mean + standard deviation of the observed profiles (n = 15). * P < 0.05; *** P < 0.001.

Figure Lengend Snippet: (A-C) MCF 10A (A), MDA-MB-231 (B), and MCF7 (C) cells transiently expressing GFP-GOLPH3 were held in a microscope stage at 37°C. The area indicated by a white dotted-line rectangle in each set of images was bleached with a 488-nm laser set to 100% power. The fluorescence recovery after photobleaching (FRAP) was tracked by laser confocal microscopy with the 488-nm laser set to 2% power. Images were acquired before bleaching ( Pre-bleaching ), immediately after bleaching ( Bleaching ), and during the recovery of the fluorescence ( Recovery ) at approximately every 0.4-sec. Images of a representative experiment performed on each cell line are shown in each set of panels. Two images of the recovery of fluorescence are depicted with the time indicated in parenthesis in seconds. Bar, 10 μm. (D) Plot of the FRAP analysis of GFP-GOLPH3 in MCF 10A (black circles; n = 10), MDA-MB-231 (white circles; n = 10), and MCF7 (white squares; n = 10) cells. P , pre-bleaching; B ; bleaching. For simplicity, error bars are not depicted. *** P < 0.001; ns , not statistically significant. The halftime ( t 1/2 ) of maximal fluorescence recovery is indicated on the right in seconds (s).

Figure Lengend Snippet: Samples (30 μg of proteins) of rat liver cytosol ( Cyt ), rat liver Golgi membranes, and of cytosolic ( Cyt ) and membrane ( Memb ) fractions from the cell lines indicated at the right were analyzed by two-dimensional gel electrophoresis (2-D GE) and immunoblotting using antibody to GOLPH3. Samples of rat liver Golgi membranes, and of the cytosolic and membrane fractions of each cell line, were dephosphorylated with calf intestine alkaline phosphatase ( CIAP ) before processing for 2-D GE. The position of molecular mass markers is indicated on the left. The position of isoelectric point ( pI ) markers is indicated at the bottom. Red asterisks indicate the position of additional, less abundant, but distinct spots in the samples of MCF7 cells that have slightly slower electrophoretic mobility. Numbers indicate different acidic forms identified in immunoblot films subjected to different exposure times.
