PGR and cancer: Functional enrichment analysis revealed that the nine genes were associated with a number of key cancer pathways and reproductive system biological processes including: the progesterone receptor signalling pathway (GO:0050847; P-value =2.90E–03); the hormone-mediated signalling pathway (GO:0009755; P-value = 1.46E–04); and the intracellular receptor signalling pathway (GO:0030522; P-value = 3.20E–04) (Table S3).
