IL-6 family cytokines increased p-STAT3 and CTGF expression in hepatoma cells and enhanced cell proliferation. Concentrations of IL-6, LIF, and OSM in the culture supernatant ( A ). Culture supernatant was collected 24 hours after the initiation of HepG2, Alex, LX-2, THP-1, MTA, and TMNK-1 cell monoculture. IL-6, LIF, or OSM concentration was measured by enzyme-linked immunosorbent assay. THP-1 cells were pretreated with 100 ng/mL phorbol 12-myristate 13-acetate (PMA) for 48 hours to induce macrophage differentiation, and the culture medium was replaced with PMA-free medium 24 hours before supernatant collection. HepG2 cells and Alex cells were treated with recombinant proteins of IL-6 (20 ng/mL), LIF (1:1000), or OSM (20 ng/mL) ( B-D ). Cells were serum-starved for 16 hours before the addition of recombinant proteins. B , Protein expression 1 hour after recombinant protein treatment. C , mRNA expression of CTGF 3 hours after recombinant protein treatment. D , WST-8 assay at the indicated time points after treatment with recombinant proteins.

Knockdown of CTGF in HepG2 cells decreased IL-6 family cytokine expression in stromal cells, downregulated p-STAT3 expression in HepG2 cells and reduced the proliferation of HepG2 cells. Western blotting of HepG2 or Alex cells treated with recombinant CTGF protein under monoculture ( A ). Protein lysate was collected from cells 0, 0.5, 1, and 3 hours after the addition of 5 nM recombinant CTGF protein. HepG2 cells were incubated under monoculture or coculture with stromal cell lines ( B-E ). HepG2 cells were transfected with CTGF siRNA or control siRNA 48 hours before coculturing. Total proteins and RNA were collected after 24 hours of coculture. THP-1 cells had been pretreated with 100 ng/m phorbol 12-myristate 13-acetate (PMA) for 48 hours to induce macrophage differentiation before coculture.
