Figure 1. CXC chemokines expression was correlated with prognosis and immune cell patterns of PAAD. (A) showed the Heatmap expression patterns of CXC chemokines in PAAD extracted from the GEO database (GDS4102); (B) showed CXC chemokines with significant changes in expression in PAAD; (C) showed CXC chemokines whose expression was correlated with overall survival of PAAD patients; (D) showed the correlation of selected CXC chemokines with the immune cell patterns in the tumour microenvironment; (E) showed the expression pattern of CXC chemokine receptors, CXCR2, and CXCR5, in different types of immune cells. *p<0.05, ***p<0.001 when compared.
