[Correlation of Ca2+ current features of nasopharyngeal carcinoma cells with different metastatic potentiality to their moving abilities].

Background & Objective: The metastatic potentiality of malignancies is closely associated with their biological dynamic properties, which are affected by intracellular Ca2+ current activity. This study was to investigate the correlation of Ca2+ current features of sub-clonal nasopharyngeal carcinoma (NPC) cell lines 5-8F and 6-10B with different metastatic potentiality to their moving abilities.

Methods: 5-8F cells, with higher metastatic potentiality, and 6-10B cells, with lower metastatic potentiality, were cultured with herbal medicine-containing serum, which holds significant metastasis-inhibiting effect on tumor cells.
