CYP1A1 and lung carcinoma: Pan et al. used a mouse lung cancer model to find that circFLNA promoted the proliferation, migration, and invasion of lung cancer cells through the sponge effect of miR‐486‐3p; the circFLNA‐miR‐486‐3p‐XRCC1/CYP1A1 regulatory axis was established through subsequent mechanistic experiments.31
