Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was utilized to analyze adenomyotic and normal myometrial tissues from ten AM patients who underwent hysterectomy with myometrial fibrosis confirmed by Masson staining. This analysis established comprehensive proteomic profiles of adenomyosis patients and revealed widespread alterations in the proteome and metabolome within normal and fibrotic myometrium. Key proteins and signaling pathways linked to myometrial fibrogenesis were identified based on proteomic data.
