COL1A2 and ocular melanoma: The ALP expression response to 1,25OHD was found in the similar pattern as COL1A2 at 24 h, 48 h, and 3 days except 10 and 50 nM 1,25OHD at 24 h (p < 0.05); 1 and 5 nM 1,25OHD inhibited ALP expression induced by OM treatment, whereas 10 and 50 nM 1,25OHD had no inhibitory effects on ALP expression at 24 h (Figures 3E–G).
