STING1 and adenomyosis: Therefore, in the current study, we investigated cGAS–STING pathway activation in uterine adenomyotic lesion tissues by quantitative real‐time reverse‐transcription polymerase chain reaction (qRT‐PCR) and immunohistochemical staining and analyzed the correlation of key cGAS–STING pathway factor expressions and the clinical outcomes in adenomyosis patients.
