hsa-circ-000684 expression was significantly correlated with lymph node metastasis and TNM staging in GC patients; proposed as a potential therapeutic target.
hsa-circ-000684 is upregulated in gastric cancer tissues and cell lines. It promotes GC proliferation, migration, invasion, angiogenesis/tube formation, and xenograft growth by acting as a miR-186 sponge and increasing ZEB1 expression. Its expression correlates with lymph node metastasis and TNM stage, suggesting biological and potential therapeutic relevance.
