KEGG enrichment analysis was performed by KOBAS 2.0 (http://kobas.cbi.pku.edu.cn/home.do).
Caenorhaditis elegans pathways were used as a reference. The ESP corresponding to each pathway can be found in Table S9.
Pathway databases mapped by KOBAS including KEGG pathway: http://www.genome.jp/kegg/pathway.htm1; reactome: http://www.reactome.org/ReactomeGWT/entrypoint.htm1; PANTHER: http://www.patherdb.org/.
Pathway identified in specific database.
“-” means not given.
The number of input proteins mapped to the particular pathway.
The number of identified proteins mapped to the particular pathway.
Only significant results (p<0.05) were shown.
The statistical method was a hypergeometric test, whereas the FDR correction method was from Benjamini and Hochberg (1995).
