Fig. 5From: 1-MT inhibits the invasion of CBP-resistant ovarian cancer cells via down-regulating IDO expression and re-activating immune cells functionKilling ability of the NK cells which were co-cultured with SKOV3, SKOV3/CBP and SKOV3/CBP + 1-MT cell lines as measured by LDH activity assay. Note:*P < 0.05 represents SKOV3/CBP VS SKOV3, **P < 0.05 represents SKOV3/CBP + 1-MT VS SKOV3/CBPBack to article page
