Table 3 Comparative production of IL-6/IL-6Rα by P-NPC and metastasis-derived NPC cell lines at day 3 in vitro culture

From: Differential baseline and response profile to IFN-γ gene transduction of IL-6/IL-6 receptor-α secretion discriminate primary tumors versus bone marrow metastases of nasopharyngeal carcinomas in culture

Variable P-NPC cell lines
(n = 5)
Metastasis-derived NPC cell lines
(n = 3)
p value#
IL-6 (pg/ml) 60.8 ± 50.7 787.7 ± 522.9 0.025
IL-6Rα (pg/ml) 609.5 ± 252.8 124.6 ± 90.1 0.025
  1. Results were expressed as mean ± SD. p values were calculated by using #Mann-Whitney U test for comparison of IL-6 and IL-6Rα production in culture.
