In early-stage ovarian cancer, the overexpression of the Switch/sucrose non-fermentable-related matrix-associated actin-dependent regulator of chromatin subfamily E member 1 (SMARCE1), which is a gene involved in chromatin remodeling, correlated with higher infiltration of CD8+ T cells through increases in CXCL9 and CCL4. This evidence concerns the gene CXCL9 and ovarian cancer.
