WormBase Gene ID  ? WBGene00003336 Gene Name  mir-242
Sequence Name  ? F36A4.16 Brief Description  mir-242 encodes a microRNA, a small non-protein coding RNA and appears to have a potential ortholog in C. briggsae; mir-242 is weakly expressed at all life stages in normal worms and in glp-4(bn2) mutant worms; many of the known microRNAs are involved in post-transcriptional regulation of genes; the precise function of miR-242 is unknown.
Organism  Caenorhabditis elegans Automated Description  Is affected by several genes including prg-1; alg-1; and alg-2 based on tiling array and RNA-seq studies. Is affected by nicotine based on quantitative PCR and RNA-seq studies.
Biotype  SO:0001265 Genetic Position  IV :0.060421 ±0.01312

Bacteria infection: Pseudomonas aeruginosa PA14. 24 hours of exposure. Small RNAs (21-26nt) that showed significantly increased expression after L4 animals were exposed to P .aeruginosa strain PA14 for 24 hours. DESeq2, FDR < 0.05 WBPaper00056868:P.aeruginosa_upregulated_smallRNA
  Potental DAF-12 target genes identified by ChIP-chip analysis performed on strain ALF4 [daf-12 Affymetrix TAS software that computed for each probe estimates of fold enrichment (in linear scale) over hybridization with input DNA. At the same time, TAS calculated for each probe a p-value by applying a Wilcoxon signed rank test. A threshold of 2.5 was selected, which corresponds to probe intensities approximately 2.5 times stronger on the ChIP array than on the Input array. Additional TAS threshold parameters were MinRun=180 bp, MaxGap=300 bp. TAS analysis showed that the selected threshold of 2.5 corresponds approximately to a p-value of 0.01.

  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
  Micro RNAs that showed significantly increased expression in day 8 adults comparing to in day 1 adults in hypodermis. Differentially expressed miRNAs were identified using DEGseq based on unique molecular identifier (UMI). A minimum UMI sum of 10 in 3 replicates was set as the threshold of expression. MiRNAs with more than five reads were defined as expressed. Differential expression of miRNAs was analysed by t-test (P value < 0.05 and fold-change > 1.5 or < 0.67) after Box-Cox transformation. MiRNA targets were identified by TargetScanWorm (Release 6.2) and Pearson Correlation Coefficient smaller than -0.2. WBPaper00066447:Day8_vs_Day1_upregulated_hypodermis
  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 up 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.
