Figure Lengend Snippet: scEMC10 inhibits glucose uptake and GLUT4 expression in skeletal muscle cells . A , L6-GLUT4myc myotubes were treated with 1 μg/ml recombinant scEMC10 protein for various times as indicated in the presence of 100 μmol/l 2-NBDG. 2-NBDG uptake into the myotubes was measured at the FITC channel by a flow cytometer. Meanwhile, 2-NBDG uptake stimulated by 100 nM insulin for 30 min was used as a positive control. B , L6-GLUT4myc myotubes were treated with 100 nM insulin in combination with or without 1 μg/ml recombinant scEMC10 protein for the times as indicated. 2-NBDG uptake into the myotubes was measured. C–F , C2C12 myotubes were treated with recombinant scEMC10 protein at different concentrations as indicated for 12 h, and then the levels of GLUT4 mRNA ( C ) and protein ( E ) were determined by quantitative PCR and Western blot, respectively. C2C12 myotubes were treated with 1 μg/ml recombinant scEMC10 protein for various times as indicated, and then the levels of GLUT4 mRNA ( D ) and protein ( F ) were determined by quantitative PCR and Western blot, respectively. All cell culture experiments were repeated three to four times. All data are presented with means ± SD. In experiments where samples were prepared in several batches, the control conditions were set at 100% in individual experiments and therefore had no error estimates. Statistical analyses were performed using unpaired two-tailed Student's t test, and significant differences were indicated with p values. ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001, and ∗∗∗∗ p < 0.0001. 2-NBDG, 2-[ N -(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxy- d -glucose; scEMC10, secreted isoform of endoplasmic reticulum membrane protein complex subunit 10.
