Delineation of the 3p14.1p13 microdeletion associated with syndromic distal limb contractures
2014
International audience; Distal limb contractures (DLC) represent a heterogeneous clinical and genetic condition. Overall, 20–25% of the DLC are caused by mutations in genes encoding the muscle contractile apparatus. Large interstitial deletions of the 3p have already been diagnosed by standard chromosomal analysis, but not associated with a specific phenotype. We report on four patients with syndromic DLC presenting with a de novo 3p14.1p13 micro-deletion. The clinical features associated multiple contractures, feeding problems, developmental delay, and intellectual disability. Facial dysmorphism was constant with low-set posteriorly rotated ears and blepharophimosis. Review of previously r…
Analysis of eIF4E gene sconfering resistance to Pea seed-borne mosaic virus (PSbMV) and other potyviruses in pea
2013
Pea seed-borne mosaic virus (PSbMV) belongs among the most frequent viral pathogens causing severe losses in field pea and other legumes. These losses might be prevented by growth of resistant varieties. Resistance to the common P1 strain of PSbMV isconferred by a single recessive gene (eIF4E), localized on LG VI (sbm-1 locus), while to lentil L1 strainis localized on LGII atsbm-2locus. Gene-specific single nucleotide polymorphism and co-dominant amplicon length polymorphism markers were developed. From the comparison of genotype verses phenotype for selection of resistance/susceptibility in F2 plants, there was a 26% discrepancy between the PCR and ELISA-based assays with potentially susce…
Common gene expression strategies revealed by genome-wide analysis in yeast
2007
A comprehensive analysis of six variables characterizing gene expression in yeast, including transcription and translation, mRNA and protein amounts, reveals a general tendency for levels of mRNA and protein to be harmonized, and for functionally related genes to have similar values for these variables.
Yeast mRNA cap-binding protein Cbc1/Sto1 is necessary for the rapid reprogramming of translation after hyperosmotic shock.
2011
Global translation is inhibited in Saccharomyces cerevisiae cells under osmotic stress; nonetheless, osmostress-protective proteins are synthesized. We found that translation mediated by the mRNA cap-binding protein Cbc1 is stress-resistant and necessary for the rapid translation of osmostress-protective proteins under osmotic stress.
Human inducible nitric oxide synthase (iNOS) expression depends on chromosome region maintenance 1 (CRM1)- and eukaryotic translation initiation fact…
2012
Human inducible nitric oxide synthase (iNOS) is regulated on the expressional level mostly by post-transcriptional mechanisms modulating the mRNA stability. Another important step in the control of eukaryotic gene expression is the nucleocytoplasmic mRNA transport. Most cellular mRNAs are exported via the TAP/Nxt complex of proteins. However, some mRNAs are transported by a different mechanism involving the nuclear export receptor CRM1. Treatment of DLD-1 cells with the CRM1 inhibitor leptomycin B (LMB) or anti-CRM1 siRNAs reduced cytokine-induced iNOS expression. We could demonstrate that the iNOS mRNA is exported from the nucleus in a CRM1-dependent manner. Since CRM1 itself does not poss…
