Project description:To investigate the structure of the bodywall muscle differentiation network, we sought to both identify what these transcription factors regulate in bodywall muscle. Through loss of function analysis, we identified genome-wide regulatory targets of hlh-1 and unc-120 using RNA-seq. 1445 targets of hlh-1 and 3674 targets of unc-120 were identified, with 760 of these genes being targets of both. Crosstalk was identified between the networks of hlh-1 and hlh-8, which is involved in non-bodywall muscle development. In the process, we quantified bodywall muscle RNA. Our data suggest that shared target genes and overlapping regulation buffer the hlh-1 and unc-120 mutant phenotypes. RNA expression genome-wide in the early embryo

Project description:To investigate the structure of the bodywall muscle differentiation network, we sought to both identify what role HLH-1 binding has in this regulation. We mapped the relationship between the regulatory targets and HLH-1 binding, as measured by ChIP-seq in animals enriched for bodywall muscle tissue through RNAi feeding. While regulatory targets are enriched for HLH-1 binding, the majority of HLH-1 binding actually occurs away from genes that are affected by hlh-1 loss of function. Nevertheless, HLH-1 binding is associated with both the expected E-box and, near genes belonging to specific regulatory subgroups, novel motifs that may serve as binding sites for cooperative transcription factors.

Project description:We show that striated muscle-expressed genes affected by reduction in UNC-120/SRF activity are not similarly affected by absence of the FHOD-1 formin. This suggests FHOD-1 does not affect striated muscle development via promotion of UNC-120/SRF-dependent transcription.

Project description:This project includes two proximity labeling experiments, one to establish the vicinity of UNC-45 under non-stress conditions and one to examine changes in the vicinity of UNC-45 under optogenetically induced mechanical muscle stress. The first non-stress experiment consists of 15 samples after biotin-streptavidin pull-down in 5 replicates of 3 conditions (3 transgenic C. elegans strains). Transgenic C. elegans strains expressing the mutant BirA biotin ligases miniTurbo and TurboID in body wall muscle cells were used to compare a proximity-labeled strain expressing an UNC-45-miniTurbo-2xHA fusion protein in the muscle cells (PP3135 unc-119(ed4)III; hhIs241[unc-54p::unc-45::miniTurbo::2xHA; unc-119(+)]) with a strain expressing the biotin ligase TurboID-2xHA without fusion protein in muscle cells (PP3138 unc-119(ed4)III; hhIs242[unc-54p::TurboID::2xHA; unc-119(+)]) to find transient interactors of the myosin chaperone UNC-45 in muscle. As a control, we included a strain expressing a transgenic UNC-45-FLAG protein in the body wall muscle (PP1017 unc-119(ed4)III; hhIs84[unc-119(+); unc-54p::unc-45::FLAG]). Biotinylated proteins in 2.5 mg lysates of these strains were pulled down with streptavidin sepharose beads and identified by mass spectrometry. The second mechanical stress experiment consists of 10 samples after biotin-streptavidin pull-down in 5 replicates of 2 conditions. A transgenic C. elegans strain expressing the biotin ligase miniTurbo fused to UNC-45 in body wall muscle cells was crossed with a transgenic strain expressing the optogenetic channelrhodopsin mutant ChR2(C128S;H134R)-FLAG in body wall muscle cells (PP3358 hhIs241[unc-54p::unc-45::miniTurbo::2xHA; unc-119(+)]; hhIs251[myo-3p::ChR2(C128S,H134R)-FLAG::unc-54 3'UTR, Cbrunc-119(+)]). The latter transgene is used to contract the worms’ muscles by blue light illumination to induce mechanical muscle stress. The optogenetic channel is activated by adding the cofactor all-trans retinal (ATR) to its food source E. coli OP50. In this experiment, we compared proximity-labeling in the UNC-45-miniTurbo-2xHA expressing strain under conditions with ATR (L+, treatment, contraction) with proximity-labeling in the UNC-45-miniTurbo-2xHA expressing strain under conditions without ATR (L-, control, no contraction) to find transient interactors of the candidate UNC-45 in muscle under mechanical stress. Biotinylated proteins in 2.5 mg of lysates of these strains were pulled down using streptavidin sepharose beads and identified by mass spectrometry.
