SYT7 and neoplasm: We investigated the underlying mechanism in which the response of 8‐oxoguanine DNA glycosylase (OGG1) to the oxidative signal 8‐oxo‐7,8‐dihydroguanine (8‐oxoG) serves as an upstream event, thereby activating synaptotagmin 7 (SYT7) gene transcription, increasing EVs release and subsequently promoting tumour metastasis.
