Figure Lengend Snippet: Effects of IL-6 on cellular proliferation. (A) RNA and protein expression of IL-6 receptor in various cancer cells from the HPA database ( https://www.proteinatlas.org/ENSG00000160712-IL6R/cell+line , accessed on 29 Nov 2025). (B) Luciferase reporter assay for measuring RPMI 8226 cells activity with or without THP-1 cells, and IL-6 (5 ng/ml) for 48 hours. The seeding number of MM cells was 10,000. THP-1 cell numbers (THP-1 N.) were varied at 2000 (2K), 4000 (4K), 8000 (8K), and 10,000 (10K). (C) THP-1 cells were stimulated with IL-6 at concentrations of 0, 5, or 10 ng/ml for 24 hours. At the end of incubation, mRNA expression levels of iNOS and CD163 in THP-1 cells were quantified by qRT-PCR, and the ratio was determined by comparing the 2-ΔΔCt values of CD163 and iNOS. N = 9. ****p <0.0001.
