meg-3 meg-4 upregulate endogenous sRNAs targeting RNAi genes and downregulate their mRNAs
meg-3 meg-4 mutants are defective in exogenous RNAi signal amplification
We combined in vivo expressed GFP-tagged MEG-3 (GEI-12) with label-free quantitative proteomics to identify protein-protein interactions of MEG-3 in early C. elegans embryos.

The hrde-1 mutation suppresses the rde-11 and sid-1 sRNA upregulation phenotype of meg-3 meg-4 mutants
sRNAseq was conducted on four independently generated meg-3 meg-4 lines, and upregulation of sRNAs targeting several RNAi genes was found. mRNAseq found that the transcript levels for several of these genes was also down. meg-3 meg-4 mutants also showed a similar pattern of sRNA misregulation as the...

Worms were fed a dsRNA trigger against the pos-1 gene and subjected to sRNAseq to see if they could amplify the exogenous RNAi trigger. meg-3 meg-4 were not able to amplify the signal as robustly as wild-type.

sRNAseq was conducted on the hrde-1; meg-3 meg-4 triple mutant, revealing that the hrde-1 mutation suppresses the rde-11 and sid-1 sRNA upregulation phenotype of meg-3 meg-4 mutants .
