prde-1 mRNA Is Present in PLM, and
prde-1 Inhibits Axon Regeneration Cell-Autonomously(A) smFISH shows
prde-1 mRNAs in the cytoplasm of PLM neuron labeled with Pmec-7-gfp (muIs32). Right bottom shows no probe control.(B) Schematic of gfp KI into
prde-1 genomic locus (
ju1534). See also Figure S2A.(C) Confocal image of endogenous GFP::PRDE-1 fluorescence in the germline nuclei in the
prde-1 (
ju1534) gfp KI animals.(D) Schematic of depletion of GFP-tagged PRDE-1 protein using GFP-DEGRON (modeled after Wang et al., 2017).(E) PLM axon regrowth 24 hr post-axotomy. Data are represented as mean +- SEM. Student's t test. Number of animals is shown within columns. Bottom:representative images of PLM neurons 24 hr post-axotomy. Red-orange arrowhead, site of axotomy.(F) PLM axon regrowth 24 hr post-axotomy in transgenic animals expressing
prde-1 driven by tissue-specific promoters for mechanosensory neurons (Pmec-4),motor neurons (Punc-25), or muscle (Pmyo-3) in a
prde-1(
mj207) background. Data are represented as mean +- SEM. One-way ANOVA followed by Tukey'smultiple comparison tests. Number of animals is shown within columns.
