Ghrelin inhibited HO-8910 PM cell growth. A BrdU incorporation by HO-8910 PM treated with ghrelin at 0, 0.1, 1, 10, and 100 nM. B MTT assay of HO-8910 PM under 10 nM ghrelin treatment at indicated times. C-D Plate colony formation assay shows the images of HO-8910 PM treated with 10 nM ghrelin for 7 days (C) and the quantification of plate colony formation assay (D). Data are shown as mean ± SD from three independent experiments. * p < 0.05, **p < 0.01
