What is more, we found these DECs have the potential to regulate the function of miRNAs as a sponge, and a novel interaction network ‘mmu_circ_0001520/mmu‐miR‐193b‐3p/MAPK10’ was also predicted and validated by qRT‐PCR, which probably took part in the development of AIH. The gene discussed is MAPK10; the disease is autoimmune hepatitis.
