CXCL1 and cancer: Even more relevant, a 42-cytokine antibody array overlaid with CSC supernatants revealed the upregulation of two cancer-related cytokines, GRO-1 (CXCL-1) and IL-8 (CXCL-8), upon 24 h of exposure of the cell to 100 MOI of live Fn (Figure 2C), a finding that is perfectly aligned with a recent report by Casasanta et al. [10] in HCT-116 cells.
