In contrast, ovarian adenocarinomas were more frequently positive than adenomas for the Notch ligands Jagged 2 (P=0.04, Fisher's exact test, two-sided probabilities are shown without adjustment for multiple testing) and Delta-like-1 (P=0.056), for the modulator of ligand specificity Manic Fringe (P=0.0007) and for the downstream transcription factor Transducin-like Enhancer of split-1 (TSL1; P=0.01). Here, JAG2 is linked to adenoma.
