CD8A and cancer: The expression of FRZB was positively correlated withmost immune cells, such as NK cells (r=0.332, P<0.001), B cells (r=0.503,P<0.001), regulatory T cells (Tregs) (r=0.302, P<0.001), CD8+ T cells(r=0.440, P<0.001), cancer-associated fibroblast (r=0.308, P<0.001), andCD4+ T cells (r=0.460, P<0.001) (Figure5A, Supplementary TableS4).
