Figure Lengend Snippet: Effect of Lem4 on tyrosine phosphorylation of signal proteins in HEK293T cell line, as detected by tyrosine phosphorylation ProArray (Full Moon BioSystems). Phosphorylation levels were increased by at least 30% at 30 sites and decreased by at least 30% at four sites in the cells overexpressing Lem4-GFP. Red dashed line indicates the level of phosphorylation in the control GFP-expressing cell line.

Figure Lengend Snippet: TRPC3 expression and SOCE in melanoma. a Representative images of immunohistochemical staining of HE, MART1, and TRPC3 in a melanoma primary tissue microarray (stage II) (original magnification, b ×200). The calibration bars represent 200 µm. b mRNA expression in various melanoma cell lines. SK-Mel-2 is a skin metastasis melanoma cell line with NRAS mutation, SK-Mel-24 is a lymph node metastasis cell line with BRAFV600E mutation, SK-Mel-187 is also a lymph node metastasis cell line, C8161 is a metastasis cell line with wild-type BRAF, and HEMA-LP is a skin melanocyte cell line. TRPC3 mRNA is widely expressed in human melanoma cell lines, independently of BRAF mutation. c Immunoprecipitation for TRPC3 and STIM1 was performed. d Cytosolic Ca2+ level in C8161 cells is shown as mean ± SD (n = 8–9). SOCE was examined in the presence or absence of DMSO (vehicle control 1 µM) or Pyr3 (1 µM) in C8161. Pyr3 inhibited SOCE in C8161 cells. Pyr3 was added after the addition of Ca2+. The Ca2+ signal was immediately decreased, indicating that Pyr3 inhibits SOCE in melanoma cells. Data in each panel are averages of eight or nine cells

Figure Lengend Snippet: Pyr3 inhibits phosphorylation of STAT5 and Akt. a Representative images of Akt phosphorylation are shown. Densitometric analyses (bar graph) of Western blots showed that phosphorylation of Akt was inhibited by TRPC3 inhibitor, Pyr3 (n = 4, **p < 0.01, ns not significant). b Protein phosphorylation microarray analysis in the presence of Pyr3. C8161 cells were incubated with DMSO (vehicle control) or Pyr3 (10 μM) for 15 min. The Y-axis shows the signal ratio of phosphorylated to non-phosphorylated protein in the presence of Pyr3 as a percentage of that of the DMSO control. c Representative images of STAT5 phosphorylation. Densitometric analyses (bar graph) of Western blots showed that phosphorylation of STAT5 was inhibited by Pyr3 (n = 4, *p < 0.05, ns not significant)
