Since NGAL is one of the 1α,25(OH)2D3 and MART-10 responsive gene in snu308 cells, to further understand NGAL role in 1α,25(OH)2D3 or MART-10 mediated growth inhibition in human CCA cells, we thus treated SNU308-NGALsi cells with 1α,25(OH)2D3 or MART-10 and compared the result with that shown in Fig. 1b. The gene discussed is LCN2; the disease is cholangiocarcinoma.
