Delisheng Injection (), a Chinese medicinal compound, enhanced the effect of cis-platinum on lung carcinoma cell line PGCL3.

ABSTRACT

OBJECTIVE: To investigate the effect of Delisheng Injection (, DLS), a Chinese medicinal compound, DLS combined with cis-platinum (DDP), an active agent used in lung cancer chemotherapy, on a human highly metastatic giant lung carcinoma cell line PGCL3. METHODS: The suspended PGCL3 cells at 10(5) /mL cultured in 96-well tissue culture plates were divided into 4 groups DLS treatment group (2 µL/mL, 5 µL/mL, 10 µL/mL, 25 µL/mL), DDP treatment group (1 µg/mL, 2 µg/mL, 5 µg/mL, 15 µg/mL), combined DLS with DDP treatment group (DLSDDP 2 µL/mL1 µg/mL, 5 µL/mL2 µg/mL, 10 µL/mL5 µg/mL, 25 µL/mL15 µg/mL) and a control group. The cytotoxicity of DLS with different concentrations (2 µL/mL, 5 µL/mL, 10 µL/mL, 25 µL/mL) on PGCL3 cells was determined by 3-(4,5)-dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay. Effect of DLS on adhesion of PGCL-3 cells was tested by cell-matrigel adhesion assay. Chemotactic movement model of transwell camerula was used to determine the effect of DLS on invasion and migration of PGCL-3 cells. RESULTS: Compared with the control group, DLS (2 µL/mL, 5 µL/mL, 10 µL/mL, 25 µL/mL) could significantly decrease cell proliferation, adhesion, invasion and migration abilities (P <0.05). Cell adhesion, invasion and migration abilities were significantly decreased after combination treatment of DLSDDP (2 µL/mL1 µg/mL, 5 µL/mL2 µg/mL, 10 µL/mL5 µg/mL, 25 µL/mL15 µg/mL) compared with DDP single-agent treatment (1 µg/mL, 2 µg/mL, 5 µg/mL, 15 µg/mL, P<0.05), respectively. CONCLUSIONS: DLS single-agent has a satisfying inhibition effect in PGCL3 cell line and DLS might enhance the inhibition effect of DDP on cancer metastasis. Our research provided a experimental basis about the treatment on highly metastatic lung caner.
