Abstract:
BACKGROUND:In esophageal cancer chemotherapy, inhibiting proliferation of tumor cels and tumor stem cels can be effectively improved by using appropriate sensitive agents.
OBJECTIVE:To explore the effect of molybdenum on ECA-109 cel chemosensitivity and p75NTR cel inhibition in esophageal carcinoma cels.
METHODS:ECA-109 cels at logarithmic phase were selected and randomly divided into blank control group, cisplatin group, molybdenum group and molybdenum+cisplatin group (combination group). Molybdenum and cisplatin at different concentrations were used in the three groups. MTT assay was used to detect ECA-109 cel proliferation and growth; flow cytometry was used to detect the proportion of P75NTR cels.
RESULTS AND CONCLUSION:Cisplatin at different concentrations showed a certain inhibitory role in ECA-109 cels, which had an increasing kiling effect on esophageal carcinoma stem cels at dose- and time-dependent manner. Molybdenum alone had no remarkable kiling effects on inhibiting ECA-109 proliferation and esophageal carcinoma stem cels. Combination of molybdenum and cisplatin was found to have an enhanced effect to inhibit ECA-109 cels and to kil esophageal carcinoma stem cels in a dose- and time-dependent manner, which was significantly different from the cisplatin group and blank control group (P < 0.05). These findings indicate that molybdenum can promote and enhance the inhibitory effect of cisplatin on ECA-109 and p75NTR cels, which can be used as a chemosensitizer.
