Supplementary Table 1. Effect of YMGKI-1 Treatment on Cancer Cell Lines

Supplementary Figure S1. YMGKI-1 affected the cell viability of SAS-HN-CICs (1 × 107 cells/well of 6-well plate) but not parental SAS (5 × 105 cells/well of 6-well plate). A, Cells were treated with 0, 10, 25, 35 and 50 μg/ml of YMGKI-1 for 24 hr, afterward, stained with propidium iodide (PI) and then examined by flow cytometry. B, Morphologies of parental SAS and SAS-HN-CICs with YMGKI-1 treatment.

Supplementary Figure S2. YMGKI-1 induced caspases activation of SAS-HN-CICs. A, Crude cell extract proteins of YMGKI-1 treated SAS-HN-CICs were collected, electrophorized and analyzed by immunoblotting against anti-Cleaved PARP, anti-Cleaved Caspas-3 or anti-GAPDH serum as indicated.

Supplementary Figure S3. HN-CICs treated with metformin or rapamycin displayed slight induction cell death. A, Morphologies of SAS-HN-CICs with metformin or rapamycin treatment for 96 hr. B, SAS-HN-CICs were treated with metformin (10 mM) or rapamycin (100 nM) for 96 hr. , afterward, stained with propidium iodide (PI) and then examined by flow cytometry.

Supplementary Figure S4. SAS xenograft-derived cells were treated with 0, 10, 25 and 50 μg/ml of YMGKI-1 for 24 hr, afterward; the ALDH activity of drug treated cells was examined by flow cytometry. The data are means ± SD of triplicate samples from three experiments (***, P < 0.005).
