DPT and escherichia coli infection: To explore the effect of lncRNA-CR33942 on the Imd pathway, we examined the expression levels of Dpt and AttA, two marker AMPs of the Imd pathway, in lncRNA-CR33942-overexpressing, lncRNA-CR33942-RNAi, and lncRNA-CR33942 + lncRNA-CR33942-RNAi co-overexpressing flies at different time points (0, 6, and 12 h) after E. coli infection.
