Regulated By Treatment	Description	Algorithm	Primary Identifier
	miRNAs that showed increased expression after exposure to graphene oxide (GO)	The dysregulated expression of miRNAs in GO-exposed nematodes was analyzed by DESeq (an R package, a powerful tool to estimate the variance and test for differential expression). The data were extracted as up- or down-regulated miRNAs according to a cutoff of 2 fold change, and were presented in the scatter diagram after normalization.	WBPaper00045209:graphene-oxide_upregulated
	miRNA with decreased expression in N2 1-day post L4 adult hermaphrodite comparing to in N2 L4 larva.	DEGseq and GFOLD were used to analyze miRNAs expression. Authors chose miRNAs which had more than two-fold difference in expression (P < 0.001, q < 0.01 of Storey) from DEGseq, and miRNAs which had more than two-fold difference in expression (GFOLD score > 0 for up-regulation and GFOLD score < 0 for down-regulation) from GFOLD outcomes. Then authors obtained the intersection of up-regulated miRNAs and down-regulated miRNAs for each stage from the chosen miRNAs, respectively.	WBPaper00045316:miRNA_N2_adult_vs_L4_downregulated_adult

	MicroRNAs that showed significantly decreased expression in alg-5(ram2), comparing to in N2.	DESeq2, Fold change > 1.5.	WBPaper00051404:alg-5(ram2)_downregulated_miRNA
	micro RNAs that exhibit changes in expression during adulthood (p-value < = 0.05).	Authors searched for targets with seed matches of perfect Watson-Crick base-pair complementarity to positions two-eight of the miRNAs (counting from the 5' end). In order to consider these seed matches as potential target sites, authors required a minimal cut-off for binding specificity of the remainder of the miRNA to the target. Recent evidence suggests that this is not required for function in humans, but 3' binding does occur in studies of C. elegans. Authors used the scoring algorithm from Robins et al. (2005). The binding cut-off is determined by creating a second-order Markov model of the background for the 3' UTRs. The cut off was p-value < = 0.05.	WBPaper00028344:adult_expr_change
