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.

HeLa or MCF10A cells were seeded in a 48 well plate at a density of ~2×104 cells/well 24 h prior to the experiment. On the following day, cells were washed one time with phosphate buffered saline (PBS) and incubated with following endocytic inhibitors in serum free media for 1 h at 37 °C: cytochalasin D (10 μg/mL), methyl-β-cyclodextrin (5 mg/mL), nocodazole (10 μg/mL), 3 mg/mL NaN3/50 mM 2-deoxyglucose, wortmannin (100 ng/mL), pertussis toxin (100 ng/mL), U-73122 (4 μg/mL), polyinosinic acid (10 μg/mL), chlorpromazine (10 μg/mL) and dynasore (80 μM). The concentrations of the inhibitors were used as described in previous reports.[39 (link)] After 1 h, media were replaced with fresh media containing the inhibitors with NPs (100 nM) and further incubated for 1 h at 37 °C. Untreated cells and cells treated with only NPs (no inhibitor) were used as negative and positive controls, respectively. After incubation, cells were washed three times with PBS and lysis buffer was added to each well. All lysed cell samples were then further processed for ICP-MS analysis (vide infra) to determine the intracellular amount of gold. All inhibitors were purchased from Sigma except for dynasore, chlorpromazine, and pertusis toxin that were obtained from Fisher Scientific. Particle uptake (%) was calculated based on the following equation:
NP uptake(%)=(NP uptake in presence of inhibitorsNP uptake in absence of inhibitors)×100

fASM cells (or adult ASM cells) were grown to 50% confluence in 8-well chambers (Lab-Tek, Rochester, NY)) and serum starved. Since the intent of this study was to explore the CaSR which is sensitive to [Ca2+]o, cells were finally Ca2+-deprived for 12h prior to experimentation. Cells were loaded with the Ca2+ indicator Fura-2/AM (5 μM; ThermoFisher Scientific, Scotts Valley CA) for 30 min in 0 mM [Ca2+]o and then washed. Depending on the protocol, cells were then treated for 1h with either medium (vehicle), 10 μM calcimimetic (R568; Tocris/Bio-Techne, Minneapolis, MN), 10 μM calcilytic (NPS2143; Tocris), 1 μM PLC inhibitor (U73122; Tocris), 1 μM inhibitor of IP3 receptor (Xestospongin C; Sigma-Aldrich), or 100 μM ryanodine (to inhibit ryanodine receptor; Sigma-Aldrich) in media (DMEM F12) containing 0, 0.5, 1, or 2 mM [Ca2+]o. These procedures were done in separate sets of cells that were exposed to the same [Ca2+]o throughout, i.e. 0, 0.5, 1, or 2 mM Ca2+ HBSS. In separate experiments, the effect of PLC siRNA was explored (Dharmacon SMARTpool ON-TARGETplus siRNA; L-010280–00-0020), with appropriate vehicle (Lipofectamine) and nonsense siRNA controls.
Fura-2 loaded fASM or adult ASM cells were imaged on an inverted microscope (Nikon Eclipse Ti-U) using appropriate filters (340 and 380 nm excitation; 410 nM emission) with perfusion used to alter [Ca2+]o or add agonists as necessary: histamine (10 μM) or spermine (100 μM) in the appropriate [Ca2+]o environment. Baseline, peak, and amplitude of [Ca2+]i responses were recorded and analyzed.

Normal aCSF (35 °C) and normal pipette solution were used in electrophysiological recording (Ibrahim et al., 2003 (link)) (Supplemental Methods). When the cationic blocker La3+ was added to the bath, a HEPES-buffered CSF solution was utilized (Zhang et al., 2008 (link)). In some experiments, low Na+ (5 mM) HEPES-buffered CSF solution and Ca2+ free extracellular CSF solution were used, where N-methyl-D-glucamine (NMDG) replaced Na+, and Mg2+ replaced Ca2+, respectively. For experiments measuring the ramp current-voltages (I–Vs) , K+-gluconate in the normal internal solution was replaced with Cs+-gluconate (pH 7.35 with CsOH), and the extracellular solution contained Na+, K+, Ih (HCN), Ca2+ and GABAA channel blockers (in mM: NaCl, 126; 4-aminopyridine, 5; KCl, 2.5; MgCl2, 1.2; CsCl, 2; CaCl2, 1.4; CoCl2, 1; nifedipine, 0.01; HEPES, 20; NaOH, 8; glucose, 10; tetrodotoxin, 0.001; picrotoxin, 0.1). Ramp I-Vs were also recorded in a solution that both Na+ and K+ were replaced with same concentration of Cs+(pH 7.35 with CsOH).
All drugs were purchased from Calbiochem (La Jolla, CA) unless otherwise specified. Leptin was provided by Dr. Parlow (Harbor-UCLA Medical Center, Torrance, California, USA) through the National Hormone and Peptide Program. The Jak2 inhibitor (E)-N-benzyl-2-cyano-3-(3,4-dihydroxyphenyl) acrylamide a-Cyano-(3,4-dihydroxy)-N-benzylcinnamide Tyrphostin B42 (AG 490), the PLC inhibitor U73122, the less active analog U73343 and the PI3 kinase inhibitor wortmannin (Alomone Laboratories) were dissolved in dimethylsulfoxide (DMSO) as stock solutions. The selective PLCγ inhibitor 1-O-Octadecyl-2-O-methyl-rac-glycero-3-phosphorylcholline (ET-18-OCH3) was dissolved in H2O. 1, 2-Bis-(o-aminophenoxyethane)-N, N, N', N'-tetra-acetic acid (BAPTA) tetrasodium salt was dissolved in the internal solution at a 10 mM concentration. The ion channel blockers/activators used were as follows: 1-[β-[3-(4-methoxyphenyl) propoxy]-4-methoxyphenethyl]-1H-imidazole hydrochloride (SKF96365); 2-aminoethyl diphenylborinate (2-APB); flufenamic acid (FFA) and 1-(cis-9-Octadecenoyl)-2-acetyl-sn-glycerol, 2-Acetyl-1-oleoyl-sn-glycerol (OAG), all were dissolved in DMSO.

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 (see Fig. 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 in Fig. 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).
