Abstract:

OBJECTIVE: To investigate anticancer effects of 5-fluorouracil (5-FU) combined with CL, extract of Rosa roxburghii Tratt on human endometrial adenocarcinoma cell line (JEC).

METHODS: JEC cells cultured in vitro in the logarithmic growth phase were seeded in the culture plate and divided into the control group (RPMI 1640), the positive group (10(-4) mol/L 5-FU), the CL groups (at the dose of 0.01, 0.1, 1, 10, and 100 microg/mL), and the CL (0.01, 0.1, 1, 10, and 100 microg/mL) combined with 5-FU groups. Effects of 5-FU combined with CL on JEC cell growth were drawn and measured by MTT and growth curves. Effects of CL combined with 5-FU on the JEC cell differentiation was analyzed by detecting the reduction capability of nitrobenzene thiocyanate (NBT) and lactate dehydrogenase (LDH) contents in the cultured medium. Effects of CL combined with 5-FU on the JEC cell apoptosis and cell proliferation cycle were detected by acridine orange (AO)/ethidium bromide (EB) fluorescent staining and flow cytometry (FCM).

RESULTS: The proliferation inhibitory effect of CL combined with 5-FU on JEC cells was enhanced when compared with that of CL or 5-FU alone (P<0.05). The percentages of NBT positive JEC cells and apoptotic JEC cells increased in the 5-FU combined with CL groups when compared with 5-FU group or the CL group alone (P<0.05). The LDH concentration of the JEC cell culture supernate decreased in 5-FU combined with CL groups (P<0.05). Furthermore, the percentage of G0-G1 phase JEC cells treated by 5-FU combined with CL was higher than that of 5-FU or CL alone (P<0.05).

CONCLUSION: CL could enhance anticancer effects of 5-FU. Its mechanisms might be correlated with reinforcing the cytotoxicity of 5-FU, inducing cell differentiation and apoptosis, and inhibiting cell proliferation and division.
