چکیده

miRNA 5 end being fully complementary to the target mRNA, with binding of the 3 miRNA end varying. Many predictive algorithms have been produced to identify potential miRNA-target pairs. However many ignore full and near-full complementarity miRNA-mRNA pairs as they are considered unusual or potential false positives. However miRNA-mRNA pairs of this nature have been previously verified as functional in regulating a Hox gene (Yekta etal., 2004). Here we conducted a bioinformatics exploration of the possible full and near-full (to a maximum of 3 GU wobbles) miRNA-mRNA interactions across a number of different species (mouse, rat, human, chimp). We then assessed the candidate miRNA-mRNA pairs for their quality as probable targets with a specific focus in their possible involvement in developmental pathways.

Drosophila DLMO is a positive regulator of transcription during thoracic bristle development

The Drosophila LIM-Only (LMO) protein DLMO functions as a negative regulator of transcription during development of the fly wing. Here we report a novel role of DLMO as a positive regulator of transcription during the development of thoracic sensory bristles. We isolated new dlmo mutants, which lack some thoracic dorsocentral (DC) bristles. This phenotype is typical of malfunction of a thoracic...

Regulation of Apterous activity in Drosophila wing development.

Apterous is a LIM-homeodomain protein that confers dorsal compartment identity in Drosophila wing development. Apterous activity requires formation of a complex with a co-factor, Chip/dLDB. Apterous activity is regulated during wing development by dLMO, which competes with Apterous for complex formation. Here, we present evidence that complex formation between Apterous, Chip and DNA stabilizes ...

The Drosophila LIM-only gene, dLMO, is mutated in Beadex alleles and might represent an evolutionarily conserved function in appendage development.

The process of wing patterning involves precise molecular mechanisms to establish an organizing center at the dorsal-ventral boundary, which functions to direct the development of the Drosophila wing. We report that misexpression of dLMO, a Drosophila LIM-only protein, in specific patterns in the developing wing imaginal disc, disrupts the dorsal-ventral (D-V) boundary and causes errors in wing...

Overexpression Beadex mutations and loss-of-function heldup-a mutations in Drosophila affect the 3' regulatory and coding components, respectively, of the Dlmo gene.

LIM domains function as bridging modules between different members of multiprotein complexes. We report the cloning of a LIM-containing gene from Drosophila, termed Dlmo, which is highly homologous to the vertebrate LIM-only (LMO) genes. The 3' untranslated (UTR) of Dlmo contains multiple motifs implicated in negative post-transcriptional regulation, including AT-rich elements and Brd-like boxe...

Osa modulates the expression of Apterous target genes in the Drosophila wing

The establishment of the dorsal-ventral axis of the Drosophila wing depends on the activity of the LIM-homeodomain protein Apterous. Apterous activity depends on the formation of a higher order complex with its cofactor Chip to induce the expression of its target genes. Apterous activity levels are modulated during development by dLMO. Expression of dLMO in the Drosophila wing is regulated by t...
