A Femtojet Micromanipulator 5171 (Eppendorf-Brinkman Instruments) and a pump, (model Femtojet; Eppendorf) were used to control the position of the micropipette and the pressure required for the chemoattractant flow. U73122 was used to inhibit PLC, and U73343 was used as a control. To induce the formation of protrusion, a micropipette was filled with 25 nM EGF and was placed ∼5 μm from the edge of a quiescent cell, and a pressure of 16 hPa was exerted to induce flow. Time-lapse series were taken using 20× NA 1.4 infinity-corrected optics on a microscope and analyzed in ImageJ. Protrusion is measured along three lines emanating from the cell centroid: (1) the front protrusion is measured along the axis formed by the centroid and the tip of the pipette; (2) the side protrusion is measured along the perpendicular to the latter; and (3) the back protrusion is measured along the axis forming 180° with the front axis. All measurements are standardized over the corresponding distance between the centroid and the cell periphery along the corresponding axis before the introduction of the pipette.

Liposome-based transfection reagents interfered with PI(4,5)P2 stainings (not shown). Therefore, for transient transfections, COS-7 cells were treated with the nonliposomal reagent Superfect (Qiagen). On the next day, cells were fixed for 30 min at 37°C, followed by 3–5 h at 4°C with 4% paraformaldehyde in DME with 2 mM EGTA. Subsequently, cells were further processed for immunocytochemistry as described in a previous study (Wiederkehr et al. 1997 ). The first antibody binding incubation was carried out overnight at 4°C, using an antibody dilution solution consisting of PBS, with 0.2% saponin, 50 mM glycine, 0.1% BSA, and 1% FCS. Cultured hippocampal neurons from wild-type and transgenic mice were labeled 24 h after plating, according to the same protocol.
For quantitative analysis of GMC and PI(4,5)P2 clusters, all cells from randomly selected fields (400×) with substantial levels of transgene expression (30–50% of all transgene expressing cells in any given field) were included in the analysis. At least 20 cells from one dish of transiently transfected cells were analyzed for every experiment, and the values are averages from at least two independent experiments. Images from 20 × 20 μm2 bins were captured and all clusters within the bin were analyzed with NIH Image software (seeFig. 2 ).
PC12B cells were transfected stably using the Fugene 6 reagent from Boehringer. Each experiment shown in the study was carried out with at least three independent clones, with similar results. For process outgrowth assays, 100,000 PC12 cells were plated on collagen-coated (30 μg/ml) 35-mm dishes, and, where indicated, the medium was changed 1 d after plating from DME, 10% horse serum, 5% FCS (growth medium) to DME, 1% horse serum, and 100 ng/ml NGF. Where process formation (>1 cell diameter) in the absence of NGF was monitored, cells were preincubated with or without neomycin for 2 h, replated in the presence or absence of the drug, and analyzed 3 h after replating. No preincubation was carried out when LiCl or the phospholipase C (PLC) inhibitor U-73122 was used.
To analyze the distribution of the actin cytoskeleton in PC12B clones, we determined intensity profiles of RITC-phalloidin labeling across randomly selected cells. Cells were plated on a collagen-coated substratum in the absence of NGF, fixed and stained 3 h after plating, photographed under identical conditions, and were analyzed with Image software. For each analyzed cell, one rectangular bin of 10 pixels in height was placed across the center of the cell (see also schematic inFig. 6 B), and an edge-to-edge labeling intensity profile was collected. For each type of PC12B clone, such profiles had reproducible characteristic features of actin cytoskeleton distribution, as revealed when the profiles were superimposed. To highlight shared features, each of six independent profiles (i.e., six cells) was assigned the same light gray value, and overlapping areas were integrated (see Fig. 6 B).

CCK8 method was used to analyze the effects of different concentrations of U73122, MK-2206 (2HCI), and PTX on keratinocytes. Briefly, the cells were seeded in 96-well plates at a density of 1.2 × 104 cells per well. After 24 h incubation, cells were respectively treated with various concentrations of PTX (100 ng/ml, 150 ng/ml, 200 ng/ml, 250 ng/ml, 300 ng/ml, and 350 ng/ml) for 4 h or U73122 (4.5 μM, 9 μM, 13.5 μM, 18 μM, 22.5 μM, and 27 μM) for 30 min or MK-2206 (2HCI) (3 μM,6 μM, 9 μM,12 μM, 15 μM, 18 μM, 21 μM, and 24 μM) for 2 h. Following the treatment, 10 μl CCK8 was added to each well, and 2 h later, absorbance was tested at a wavelength of 405 nm using a fluorescence spectrophotometer (BD Biosciences, San Jose, CA).

NCI-H716 cells (1 × 106 cells/well) were seeded onto 12-well pre-coated plates and incubated for 48 h in siRNA solution diluted in DMEM to induce differentiation. After starvation, the cells were pre-treated with U73122 and 2-APB for 30 min. The medium was then exchanged with 1 mL/well DMEM containing 80 μM ISS, and the cells were incubated for 1 h. Then, the cell culture medium was centrifuged at 2000× g for 10 min to remove debris, and 50 μL of the supernatant was used for GLP-1 analysis. For the quantitative measurement of GLP-1 in the cell culture supernatants, a human GLP1 (7-36) enzyme-linked immunosorbent assay (ELISA) kit (ab184857) was purchased from Abcam (Cambridge, UK). The GLP-1 ELISA was performed according to the manufacturer’s protocol.
