WormMine: Gene WBGene00000556

• WormBase Gene ID: WBGene00000556
• Gene Name: cnc-2
• Sequence Name: R09B5.3
• Brief Description: cnc-2 encodes one of eleven C. elegans caenacin peptides; cnc-2 functions as a secreted antimicrobial peptide in the innate immune response: cnc-2 expression is strongly induced in the epidermis upon infection by the fungal pathogen and overexpression of cnc-2 promotes survival after D. coniospora infection; cnc-2 expression is also induced upon infection by the Gram negative bacterium Serratia marcescens; cnc-2 expression is positively regulated by the DBL-1 TGF-beta homolog, the SMA-6/DAF-4 TGF-beta receptor, and the SMA-3, but not SMA-2 and SMA-4, SMAD protein.
• Organism: Caenorhabditis elegans
• Automated Description: Involved in defense response to Gram-negative bacterium; defense response to fungus; and innate immune response. Predicted to be located in extracellular space. Expressed in hypodermis.
• Biotype: SO:0001217

	Genes significantly enriched (> 2x, FDR < 5%) in a particular cell-type versus a reference sample of all cells at the same stage.	A Mann-Whitney U test with an empirical background model and FDR correction for multiple testing was used to detect expressed transcripts (Benjamini and Hochberg 1995). Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models. Genes and TARs were called differentially expressed if the FDR was <= 0.05 and the fold change (FC) >= 2.0. To more strictly correct for potential false-positives resulting from multiple sample comparisons, authors divided individual FDR estimates by the number of samplesor sample comparisons, respectively. This resulted in an adjusted FDR of 1.3 * 0.0001 for expression above background and of 7.4 * 0.0001 for differential expression. Authors called genes selectively enriched in a given tissue if they met the following requirements: (1) enriched expression in a given tissue (FDR <= 0.05 and FC >= 2.0), (2) fold change versus reference among the upper 40% of the positive FC range observed for this gene across all tissues, and (3) fold-change entropy among the lower 40% of the distribution observed for all genes.

	Genes that show selective expression in a subset of cell types vs broadly expressed in many cell types. Correspond to 20% - 57% of enriched_genes for a given cell type.

Genes and TARs with an FDR <= 0.05 were reported as expressed above background. Authors detected differentially expressed transcripts using a method based on linear models.

6 Expression Patterns

• Primary Identifier: Expr8217
• Remark: Curated by authors based on online in-situ hybridization database (Y. Kohara, personal communication; http: Picture: N.A.
• Pattern: No expression detected.

• Primary Identifier: Expr8525
• Remark: Picture: Fig. 3 and Supplementary Fig. 3.
• Pattern: Fluorescence appeared in both the pcnc-2::mCherry and pcnc-2::GFP reporter strains when worms were infected with D. coniospora at any and all stages. The cnc-2 reporter genes were expressed exclusively in the epidermis. Authors found no induction of expression of either reporter gene after infection with the bacterial pathogens S. marcescens and P. aeruginosa or exposure to high salt.

• Primary Identifier: Expr2010263
• 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).
