SMEDWI-3 group 1 ping-pong targets form nuclear foci in the planarian epidermis. (A) Boxplots showing the log2 fold differential expression changes of the three distinct SMEDWI-3 target groups upon smedwi-3 knockdown in neoblasts (X1) and differentiated cells (Xins). Statistical significance of differential expression of the gene sets was assessed using generally applicable gene-set enrichment (GAGE) analysis with a two-sample t-test (ns, not significant). (B) GO term enrichment analysis of ping-pong degraded group 1 SMEDWI-3 targets. (C) Expression and localization pattern of three exemplary ping-pong targets of SMEDWI-3 [dapk1 (SMESG000043474.1), traf6 (SMESG000000294.1), ank1 (SMESG000076223.1)] in the planarian epidermis analyzed with whole-mount in situ hybridization (WISH). Nuclei stained with Hoechst are in blue, mRNAs are in yellow. (D) Coimmunostaining of SMEDWI-1, -2, and -3 in the epidermis on a cross-section through the planarian pharynx. SMEDWI-1 is in green, SMEDWI-2 and -3 are in red. Nuclei stained with DAPI are in blue.
