circ_0043278 may serve as a potential diagnostic and prognostic biomarker for NSCLC; increased expression was correlated with differentiation grade, distal metastasis, and TNM stage.
hsa_circ_0043278/circ_0043278 is up-regulated in NSCLC tissues and cell lines and is associated with metastasis-related clinicopathologic features. Functionally, it promotes NSCLC proliferation, invasion, migration, tumor sphere formation, and xenograft tumor growth. Mechanistically, circ_0043278 sponges miR-520f to increase ROCK1, CDKN1B, and AKT3 expression, suggesting potential biomarker and therapeutic relevance.
