WormMine: Gene WBGene00004854

• WormBase Gene ID: WBGene00004854
• Gene Name: slt-1
• Sequence Name: F40E10.4
• Brief Description: slt-1 encodes the sole C. elegans homolog of Drosophila Split, a secreted extracellular protein containing leucine-rich and EGF-like repeats that functions as a ligand for the Robo receptor; during C. elegans larval development, slt-1 acts via the SAX-3/Robo receptor, and in parallel with UNC-6/Netrin, to direct ventral axon guidance and guidance at the midline; during embryonic development, slt-1 also functions to regulate anterior-posterior migrations of the CAN neurons; slt-1::gfp reporters are initially expressed at high levels in the anterior part of the embryo, with more moderate levels seen in dorsal tail muscles and lower levels seen in cells in the center of the body; in L1 larvae, slt-1::gfp is expressed in both dorsal and ventral muscles, with higher levels seen in dorsal muscle cells; slt-1::gfp is also expressed in a number of additional cells including some neurons, pharyngeal cells, and the anal sphincter muscle.
• Organism: Caenorhabditis elegans
• Automated Description: Enables signaling receptor binding activity. Involved in generation of neurons and regulation of neuron projection development. Predicted to be located in extracellular region. Expressed in anal sphincter muscle; anterior hypodermis; body wall musculature; nerve ring neurons; and socket cell. Human ortholog(s) of this gene implicated in atrial fibrillation; myositis (multiple); and proliferative diabetic retinopathy. Is an ortholog of human SLIT1 (slit guidance ligand 1); SLIT2 (slit guidance ligand 2); and SLIT3 (slit guidance ligand 3).

	Genes with expression level regulated by genotype (N2 vs CB4856) and age at L3 larva and Late reproduction stage (96 hours at 24 centigrade).	For model 2, authors used 100 permutations to estimate the FDR threshold. Per permutation, genotypes and ages were independently randomly distributed, keeping the among-gene structure intact. Then for each spot (23,232) on the array, model 2 was tested. The obtained P-values were used to estimate a threshold for each of the explanatory factors. Authors also used a genome-wide threshold of -log10 P-value = 2, which resembles an FDR of 0.072 and 0.060 for marker and the interaction age-marker for the developing worms and FDR of 0.050 and 0.065 for marker and age-marker for the aging worms. For the physiological age effect, authors used a log10 P-value = 8 in developing worms (0.012 FDR) and -log10 P-value = 6 (0.032 FDR).	WBPaper00040858:eQTL_age_regulated_developing

7 Expression Patterns

• Primary Identifier: Expr2034120
• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type. Interactive visualizations are available as a web app (https://cello.shinyapps.io/celegans/) and can also be installed as an R package (https://github.com/qinzhu/VisCello.celegans).

• Primary Identifier: Expr1639
• Remark: Double staining with antisera against GFP and the epithelial junction protein JAM-1 (MH27) was performed to characterize embryonic expression in more detail.
• Pattern: Epidermal cells in C. elegans are born on the dorsal side of the embryo, and the epidermal sheet migrates ventrally to enclose other tissues and anteriorly to cover the head. slt-1::GFP was first detectable just as the migrating epidermal cells completely covered the head and was expressed in hyp4, hyp1, and other epidermal cells. At the 2-fold stage of embryogenesis, expression spread beyond the anterior cap of cells to other anteriorly located cells, including the most anterior head muscle cells and some anterior socket cells, a set of glia associated with head sensilla. During the second half of embryogenesis, when most cells and axons in the developing nervous system are migrating, slt-1::GFP expression was concentrated in anterior cells and excluded from the middle of the body. Expression in anterior cells, including the anterior hyp cells, continued throughout larval stages and in the adult. Around the two-fold stage of embryogenesis, slt-1::GFP expression became evident in pharyngeal cells, including the most posterior pharyngeal muscle. Expression in the pharynx persisted through the L1 stage and in the adult. Beginning at the 2-fold stage of embryogenesis, slt-1::GFP was expressed in dorsal body wall muscles in a striking asymmetric pattern. Dorsal muscle expression began in the posterior embryo and spread anteriorly by the L1 larval stage, all dorsal muscles expressed slt-1::GFP. Robust expression in dorsal muscles persisted throughout the life of the animal. slt-1::GFP was also expressed in ventral body wall muscles, beginning in the L1 stage in posterior ventral muscles and continuing to more anterior muscles in later larval stages. Throughout development, dorsal muscles expressed more slt-1::GFP than ventral muscles. slt-1::GFP was expressed in the BDU neuron in the body and the RIH and RMED neurons, which have the most anterior axons in the nerve ring. Expression was first detected in comma stage embryos, with expression restricted to a cap of anterior cells. slt-1::GFP is not expressed in ventral epidermal cells. slt-1::GFP was expressed in the anal sphincter muscle.
