    R&D Systems goat polyclonal anti human kitlg antibody
    A , KIT Y721 phosphorylation was activated by exogenous rhKITLG (100 ng/mL for 10 min following 2 h serum deprivation [ , ]) in GIST-T1 cells containing a heterozygous activating KIT mutation (n=4/group) and in GIST-T1-5R cells containing an additional, imatinib-resistant KIT mutation (n=6/group), but not in GIST882 cells lacking a WT KIT allele (n=5/group). B , Culturing with anti-human <t>KITLG</t> neutralizing antibody for 4 days inhibited baseline proliferation of GIST-T1 cells ( P <0.001; n=3; regression and 95% confidence band are shown as solid and dashed lines, respectively) and GIST-T1-5R cells ( P <0.001; n=6). The effect of KITLG immunoneutralization on GIST-T1 cells was blocked by preabsorbing the antibody with 10-fold molar excess of rhKITLG (see open symbols in the left panel, second row; n=3/group). KITLG immunoneutralization did not inhibit the proliferation of GIST882 or GIST48B cells lacking a WT KIT allele (note that GIST48B cells also express very low to undetectable levels of KIT protein, see ) and of LX-2 cells lacking KIT protein (n=3/cell line). C , Inhibition of the proliferation of GIST-T1 and GIST-T1-5R cells by siRNA-mediated knock-down of KITLG (n=4/cell line/group; P GIST-T1 : day 2: 0.008, days 4, 6 and 8: <0.001; P GIST-T1-5R : day 2: <0.02, day 4: 0.004, days 6 and 8: <0.001).

    A , Increased occupancy of the Kitl core promoter by the trithorax group-mediated, activating H3K4me2 histone modification in response to 6-h rhIGF1 (100 ng/mL) and SB415286 (30 µM) treatment in murine gastric smooth muscles. B - C , Reduced occupancy of the Kitl core promoter by the PRC2-mediated, repressive H3K27me3 histone modification ( B ) and by the PRC2 histone methyltransferase EZH2 ( C ) in response to rhIGF1 and SB415286 in the same tissues. D - F , Stimulation of KITLG expression by the indirect histone methyltransferase inhibitor Adox in murine gastric smooth muscles ( D ), LX-2 cells ( E ) and GIST-T1 cells ( F ) (n=3/group). Adox was applied for 72 h following 24-h serum deprivation. See further details in the legend to .

    A - B , Reduced occupancy of the Kitl core promoter by the repressive H3K9me2 ( A ) and H3K9me3 ( B ) histone modifications in response to 6-h rhIGF1 (100 ng/mL) and SB415286 (30 µM) treatment in murine gastric smooth muscles. C - D , Probing the role of HP1 isoforms in transcriptional repression of KITLG in LX-2 cells by siRNA- (CBX5: HP1α; 25 nM, 72 h; C ) or shRNA-mediated knock-down (CBX1: HP1β; CBX3: HP1γ; 30 µg plasmid, 72 h; D ). Note activation of KITLG expression by shRNA-mediated knock-down of HP1γ (n=3/group).

G , Stimulation of KITLG expression by the H3K9 HKMT inhibitor chaetocin in LX-2 cells (n=3/group). Drugs were applied for 24 h following 24-h serum deprivation.
