Effect of Human Acute Monocytic Leukemia Cells on Coal Tar Pitch Extract-Induced c-Jun mRNA Expression in Human Bronchial Epithelial Cells

  • Objective To explore the effect of human acute monocytic leukemia cells (THP-1) on c-Jun mRNA expression induced by coal tar pitch extract (CPTE) in human bronchial epithelial cells (BEAS-2B).

    Methods BEAS-2B cells (CTPE group) and co-cultured BEAS-2B and THP-1 cells (CC group) were both simulated by 3μg/mL CTPE, and dimethyl sulfoxide (DMSO) was used as vehicle control. The cells were collected at passage 1, 5, 10, 15, and 20. The co-cultured cells at passage 9 were further cultured to passage 10 (CC10 group) and passage 15 (CC15 group), and added 100 μg/mL tumor necrosis factor-α (TNF-α) neutralizing antibody and further cultured to passage 15 (neutralizing antibody group). The expression of c-Jun mRNA was detected by real-time fluorescent quantitative polymerase chain reaction.

    Results The expression levels of c-Jun mRNA in BEAS-2B cells at passage 15 and 20 in the CC group were both increased compared with those in the CTPE and DMSO control group (P<0.05). The expression level of c-Jun mRNA after adding TNF-α neutralizing antibody was increased compared with the CC10 group and decreased compared with the CC15 group (P<0.05).

    Conclusion THP-1 could regulate the expression of c-Jun mRNA induced by CTPE through TNF-α in the BEAS-2B cells.
