Table 2 Comparison of the profiled tumour gene expression with combined expression data of eight benign ovarian cysts

From: Chromatin H3K27me3/H3K4me3 histone marks define gene sets in high-grade serous ovarian cancer that distinguish malignant, tumour-sustaining and chemo-resistant ovarian tumour cells

Histone mark Average expression difference tumour versus benign t-test P-value
All genes −0.00017 NA
Bivalent −0.24 3.1 × 10−10
H3K27me3 −0.16 2.4 × 10−8
H3K4me3 +0.013 0.073
