Fig. 4: Differential expression of transcripts involved in cell-cell adhesion, ROS response, and apoptosis.

a–p Boxplots of transcripts differentially expressed in different anatomical regions of the fallopian tube, showing expression in both ciliated and secretory segments. Point shapes are chosen based on patient information. P-values for selected comparisons are plotted. All p-values are calculated using two-sided t-test. green: fimbria; blue: infundibulum, red: ampulla, purple: isthmus; circles: pt_1, squares: pt_2, diamonds: pt_3, Lower and upper hinges of boxplot correspond to first (Q1) and third quartiles (Q3); central line corresponds to median. Whiskers of boxplot range from Q3 + 1.5*IQR to Q1-1.5*IQR. Plots (a–h) show cell-cell adhesion transcripts expressed in the fallopian tube epithelium in the discovery (n = 77) (a–d) and validation cohorts (n = 74) (e–h). Plots (i–p) show transcripts associated with reactive oxygen species or apoptosis/cell cycle expressed in the fallopian tube epithelium in the discovery (i–l) and validation cohorts (m–p).
