CBLL1 and neoplasm: Similar to the above studies’ results, Li et al. (2020) revealed the involvement of circRNA ZFR as a molecular sponge in the regulatory mechanism of cisplatin resistance in NSCLC tumor cells by competitively sponging miR-545-3p and then inhibiting the binding of miR-545-3p to the downstream target gene CBLL1 (Cbl proto-oncogene like 1).
