CD8A and neoplasm: FSCN1 expression was found to be positively correlated with ACC tumour purity (r = 0.349, p = 2.33e− 03), and negatively correlated with the infiltration signature of CD8+ T cells (r = − 0.372, p = 1.19e – 03, Fig. 2a), while FOXM1 showed a weak correlation with B cell and dendritic cell signatures (Fig. 2b).
