• Gene Name: mir-255
• Sequence Name: F08F3.11
• Brief Description: mir-255 encodes a microRNA, a small non-protein coding RNA; as mir-255 could not be detected on northern blots, its expression profile is unknown; many of the known microRNAs are involved in post-transcriptional regulation of genes; the precise function of miR-255 is unknown.

	Transcripts that showed significantly decreased expression in mrps-5(RNAi) animals comparing to animals injected with empty vector.	Differential expression was assessed using a Partial least-squares discriminant analysis (PLS-DA) using mixomics setting a variable of importance (VIP) score of greater than 1 as significant.

	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

	miRNA that showed increased expression after 20mM nicotine treatment	Statistical analysis was based on t-test for independent samples via SPSS. The results were further narrowed based on two criteria. Only the genes whose expression changed with a P < 0.05 and a fold change > 0.5, when compared to control, were considered as differentially expressed. Fold change was calculated as 2**(DeltaCt(treatment)-DeltaCt(control))-1. DeltaCt = Ct(miRNA)-Ct(aveMRNA).	WBPaper00042480:20mM_nicotine_upregulated

	miRNAs in F1 generation down regulated by exposure to 20uM and 20mM nicotine during F0 generation.	Statistical analysis was based on t-test for independent samples via SPSS to compare each of the nicotine treatments with control (i.e. low vs. control and high vs. control). Welch test correction was performed to account for unequal variance in each of the compared groups (control and treatment). In addition, to increase the statistical stringency, miRNAs differential expression was deemed significant only if it fulfilled two criteria: p value , 0.05 and expression changed by at least 50% relative to control.
