JUN and breast cancer: In the IL-17 signalling pathway, our results showed that the expression of proinflammatory factors within the range was increased, and the trend between groups, such as mmp9, il-8, jun, and mmp13, was significantly upregulated (p < 0.05) in the PS group vs. the BC group, and hsp90 was significantly downregulated (p < 0.05) in the PS group vs. the BC group.
