Fig. 6. Schematic representation for the role and mechanism of eccDNA in the DDP resistance of FaDu cells.

eccDNA combined with linear DNA results in enhancement of DNA amplification, followed higher RNA transcription level, and then more protein translated. RAB3B, which totally or partly transcripted from eccDNA, promoted the DDP resistance of FaDu cells by inducing autophagy.
