WormBase Gene ID  ? WBGene00003262 Gene Name  mir-34
Sequence Name  ? Y41G9A.7 Brief Description  mir-34 encodes a microRNA, a small non-protein coding RNA; miR-34 expression increases during adulthood, and loss of mir-34 activity results in increased adult lifespan along with increased resistance to heat and oxidative stress; in regulating adult lifespan, mir-34 functions via negative regulation of autophagy; mir-34 is conserved in C. briggsae as well as in Drosophila and humans.
Organism  Caenorhabditis elegans Automated Description  Involved in several processes, including determination of adult lifespan; negative regulation of autophagy; and response to stress. Expressed in excretory canal; hypodermis; neurons; somatic nervous system; and vulval precursor cell.
Biotype  SO:0001265 Genetic Position  X :-12.6678 ±0.001309

  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.

  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

12 hour starvation miRNA that showed significantly increated expression after 12 hour starvation in L4 larva stage. Fold change was calculated by dividing the higher counts per million by the lower, but adding the sign from the logFC to indicate direction. Authors only considered miRNA regions with at least 1 reads per-million from one of the libraries. These were tested for differential expression using the edgeR package, setting the common dispersion to 0.1 (since they did not have biological replicates) and normalizing with the TMM method. False Discovery Rates were calculated using the Benjamini & Hochberg procedure. WBPaper00048790:12h-starvation_upregulated_miRNA

    Expr13455 In predauers, Pmir-34::gfp expression was increased in amphid neurons, especially in AWC neurons. Higher expression levels were later observed in the excretory canal, seam cells and vulval precursor cells, and in ventral and dorsal nerve cord and tail neurons. Hypodermal expression appeared in day 1 dauers, and reached the highest level at the 2nd day of the dauer stage, when dauers shed their cuticle.  
    Expr13538 Many neurons (likely pharyngeal) in the head & pharynx.  
    Expr2516 No signal detected in embryos. Faint signals detected in L1, L2 and L3 larva. Intense signals were detected in L4 larva, adults, and glp-4(bn2) adults.
