Fig. 3From: DNA methylation patterns at and beyond the histological margin of early-stage invasive lung adenocarcinoma radiologically manifested as pure ground-glass opacityHeatmaps of identified DNA methylation markers across tumor and para-tumor. Horizontal axis indicates different markers, and vertical axis indicates different samples. S markers show a clear change between tumor samples (TC and TE) and para-tumor samples (P5–PN). G markers demonstrate a gradual change from TC to TE and to para-tumor samples (P5–PN)Back to article page
