Figure Legend Snippet: Stromal Derived Factor 1 (SDF-1) provokes an intracellular Ca 2+ response in the HLY-1 diffuse large B cell lymphoma (DLBCL) cell line involving intracellular Ca 2+ pool mobilization and Orai1/STIM1 extracellular Ca 2+ influx. Ca 2+ responses to SDF-1 (100 ng/mL) were measured using Fluo2-LR-AM Ca 2+ dye and recorded by videomicroscopy (Zeiss LSM 510) using ×25 objective. Black arrows indicate SDF-1 addition. Each trace represents the response of one cell and data are representative of at least three independent experiments. Typical response of unique cell (peak or peak follow by sustained plateau phase) are present as example ( Ab ). Data were processed using GraphPad prism. ( A ) Pharmacological characterization of SDF-1-induced Ca 2+ increase. Cells were recorded in extracellular saline solution (HBSS) containing 2 mM Ca 2+ (2 Ca, ( Aa )) or in Ca 2+ -free HBSS (0 Ca, ( Ac )). Cells were pre-incubated with BTP2 ( Ae ) or GSK7975A ( Af ) at 10 µM for 30 min and recorded in 2 mM Ca 2+ HBSS containing inhibitors. ( Ad , Ag ) Histograms represent areas under curves (AUC) calculated, under various recording conditions, between the application time of SDF-1 and t = 2050 s, and normalized compared to control (2 Ca or shNT). Data are expressed as mean ± SEM, * p
Techniques Used: Derivative Assay, Incubation
Figure Legend Snippet: Orai1 and STIM1 regulate basal and SDF-1-induced DLBCL cell migration in a Ca 2+ independent manner in vitro. Cell migration was assessed in 96-transwell chemotaxis chambers assay. Histograms represent mean ± SEM from at least 3 independent experiments, * p

Figure Legend Snippet: STIM1, but not Ca 2+ , regulate DLBCL dissemination in vivo. ( A ) Effect of STIM1 under-expression on HLY-1 cell dissemination. ( B ) Effect of intraperitoneal injection of BTP2 (12 µg/kg) or vehicle, three times per week on HLY-1 cell dissemination. Images were captured with a Nikon Eclipse Ci microscope equipped with a Plan Fluor 10× 0.3 NA objective. Scale bars = 150 μm. Histograms represent the quantification of positive surface for HLA-ABC staining. All tissues were delimited and to evaluate the percentage of positive surface for HLA-ABC staining on tissue, thresholding on positive and negative staining was done using Mercator software. Data are represented as mean ± SEM (n = 10), * p

Figure Legend Snippet: Orai1 and STIM1 control DLBCL cell migration through RhoA activation, ROCK, and MLC phosphorylation. ( A ) SDF-1-induced SU-DHL-4 and HLY-1 cell migration is ROCK activation dependent. Cells incubated or not with SDF-1 (100 ng/mL) were pre-treated during 20 min in the presence or not of various inhibitors (FAK inhibitor 1 µM, PD98059 a MEK inhibitor 10 µM, Wortmannin a PI3K inhibitor 10 nM, AKT inhibitor 250 nM, Y27632 a ROCK inhibitor 1 µM).

Figure Legend Snippet: Orai1 and STIM1 expression is altered in extra-nodal DLBCL. ( A ) Representative immunofluorescent staining of STIM1 and Orai1 in normal lymph node and extra-nodal DLBCL under-expressing STIM1 or Orai1. Images were acquired using Leica DMI8 microscope equipped with a 40× oil immersion objective. TMA including samples from normal lymph node (n = 26), nodal (n = 43) and extra-nodal (n = 44) DLBCL was co-immunostained using Orai1 or STIM1 antibodies revealed by donkey anti-rabbit Alexa-488 (in green) and mouse anti-human CD20 and anti-human CD19 revealed by goat anti-mouse Alexa 532 (in red). Nuclei were stained with DAPI (in blue). Scale bar = 50 µm. ( B ) Quantification of STIM1 or Orai1 alteration in DLBCL samples. After acquisition of spot fluorescence on Icys laser scanning cytometer, a segmentation analysis base on phantoms was done to determine the percentage of CD20/CD19 positive cells expressing protein of interest for each spot.
