Genetic compensation: A phenomenon in search of mechanisms.
TLDR
This review revisits studies reporting genetic compensation in higher eukaryotes and outlines possible molecular mechanisms, which may include both transcriptional and posttranscriptional processes.Abstract:
Several recent studies in a number of model systems including zebrafish, Arabidopsis, and mouse have revealed phenotypic differences between knockouts (i.e., mutants) and knockdowns (e.g., antisense-treated animals). These differences have been attributed to a number of reasons including off-target effects of the antisense reagents. An alternative explanation was recently proposed based on a zebrafish study reporting that genetic compensation was observed in egfl7 mutant but not knockdown animals. Dosage compensation was first reported in Drosophila in 1932, and genetic compensation in response to a gene knockout was first reported in yeast in 1969. Since then, genetic compensation has been documented many times in a number of model organisms; however, our understanding of the underlying molecular mechanisms remains limited. In this review, we revisit studies reporting genetic compensation in higher eukaryotes and outline possible molecular mechanisms, which may include both transcriptional and posttranscriptional processes.read more

TL;DR: These findings expand the vascular roles of GIPCs beyond those of the Vascular Endothelial Growth Factor (VEGF)-dependent, proangiogenic GIPC1-Neuropilin 1 complex, recasting GIPPs as negative modulators of antiangiogens PLXND1 signaling and suggest that PLxND1 trafficking shapes vascular development.

Investigation of Islet2a function in zebrafish embryos: Mutants and morphants differ in morphologic phenotypes and gene expression.
TL;DR: It is concluded that differentiation of the CaP’s stereotypic large inward and outward currents does not have a specific requirement for Islet2a, and the morphological phenotypes of CaP and a later-born motor neuron differed between islet 2a mutants and morphants.

TL;DR: It is shown that previously known and new genes are necessary for optimal growth under six well-studied conditions: high salt, sorbitol, galactose, pH 8, minimal medium and nystatin treatment, and less than 7% of genes that exhibit a significant increase in messenger RNA expression are also required for optimal Growth in four of the tested conditions.
