Exosomal LncRNA ZFAS1 also promotes the proliferation, migration and invasion of tumor cells from esophageal carcinoma (ESCC), and inhibits the apoptosis of ESCC cells by up-regulating STAT3 and down-regulating MiR-124, leading to the carcinogenesis of ESCC. Here, ZFAS1 is linked to esophageal squamous cell carcinoma.
