The utility of C. elegans as a model for study of miRNA function is exemplified by those miRNAs already described by forward genetics in this animal. The miRNA then acts as the specificity determinant of the silencing complex, hybridizing to complimentary sequences in the 3′UTRs of target mRNAs. miRNAs are thought to regulate mRNA translation. Massachusetts Institute of Technology: MIT OpenCourseWare, https://ocw.mit.edu. 2. Nevertheless, a recent study using stable isotope labelling by amino acids in cell culture (SILAC) identified a number of proteins, whose levels were altered after miR-1 transfection [51]. This book brings together the two disparate worlds of computational text analysis and biology and presents some of the latest methods and applications to proteomics, sequence analysis and gene expression data. The subsequent realization that the let-7 miRNA was conserved throughout the bilateria led to a search for additional small regulatory RNAs. In particular, genetic interactions might indicate genes regulated by, or regulating the same process as a given miRNA. Use OCW to guide your own life-long learning, or to teach others.

Five miRNAs and two miRNA families control the timing of larval development in C. elegans. In nematodes, at least 10% of protein-coding messages appear to be conserved targets of miRNAs [19]. A proposed protocol is shown in Figure 3. Made for sharing. Similar approaches have also been used in human cell lines and Drosophila, using Ago proteins for immunoprecipitation followed by microarray analysis [48, 49]. Surprisingly, the majority of C. elegans miRNAs are individually not required for normal development; suggestive of functional redundancy with other miRNA or protein-coding genes [35]. For this reason they were first termed short temporal RNAs (stRNAs), as their functions appeared specialized to developmental timing. Published by Oxford University Press. This interaction results in reduced translation of the target mRNA and target mRNA destabilization through a poorly understood mechanism [2, 4]. Freely browse and use OCW materials at your own pace.
