Exosomal circRNA expression profile in IPF patients and control volunteers. A The heat map of exosomal circRNA expression profile in IPF patients and control volunteers. B The volcano map of exosomal circRNA expression profile in IPF patients and control volunteers. The blue dots represent the descending circular RNA; The red dots represent rising circular RNA. C The six upregulated exosomal circRNAs in 10 IPF patients and 10 control volunteers by RT-qPCR. IPF IPF patients, non-IPF control volunteers. Each test was repeated three times. The mean differences between diagnostic groups were analyzed by Student’s t test. ***P < 0.001
