Immunoreactive interleukin-6 (IL-6) in culture supernatants of PC3 and LNCaP sublines (LNCaP/P, parental cell line of LNCaP; LNCaP/Co, control vector-only transfected cell line; LNCaP/IL-6#1, LNCaP/IL-6#2, LNCaP/IL-6#3 and LNCaP/IL-6#4, IL-6-transfected cell lines). Enzyme-linked immunosorbent assay was performed to analyse the concentrations of IL-6 protein in culture supernatant from each cell line.
