The impact of VK2 homologs (VK2-MK4, VK2-MK7 and VK2-MK9) and their concentration on the secretion of pro-inflammatory cytokines: IL-6 with addition of 100 ng/mL of LPS (A) and TNFα with addition of 100 ng/mL of LPS (B) in the RAW 264.7 mouse macrophage cell line (incubation time, 24 h). Changes in the cytokine levels was measured with respect to control sample (RAW 264.7 cells with culture medium stimulated with LPS, without VK2). Statistical significance was evaluated in comparison with RAW 264.7 cells with addition of 100 ng/mL of LPS (B and D). * p < 0.05 ** p < 0.01
