ARID1A deficiency correlated with elevated immune activity in tumour tissues. a The different IL2, IL6, and IFN γ expression levels between the two groups. b Immune infiltration score by ESTIMATE. c The difference in lymphocyte infiltration level by ssGSEA in the two groups. d-f Representative images, quantitation of immunostaining, and immunohistochemical staining for ARID1A, CD8, and CD56 expression in HCC patients (ARID1A magnification × 200; CD8 and CD56 magnification × 100). Scale bar = 100 μm or 50 μm. (* P < 0.05, ** P < 0.01, *** P < 0.001)
