Abstract
Dermatofibrosarcoma is the most common cutaneous sarcoma. Its surgical management is a technical challenge due to the high amount of substance loss. We explain a new technique of abdominal wall reconstruction by a reverse abdominoplasty with umbilical transposition. This new surgical technique allowed, in one time, the excision and the abdominal wall reconstruction. Functional and esthetic results are really satisfactory.

Abstract
Sucrose starvation of Arabidopsis (Arabidopsis thaliana) cell culture was used to identify translationally regulated genes by DNA microarray analysis. Cells were starved by subculture without sucrose, and total and polysomal RNA was extracted between 6 and 48 h. Probes were derived from both RNA populations and used to screen oligonucleotide microarrays. Out of 25,607 screened genes, 224 were found to be differentially accumulated in polysomal RNA following starvation and 21 were found to be invariant in polysomal RNA while their total RNA abundance was modified. Most of the mRNA appears to be translationally repressed (183/245 genes), which is consistent with a general decrease in metabolic activities during starvation. The parallel transcriptional analysis identifies 268 regulated genes. Comparison of transcriptional and translational gene lists highlights the importance of translational regulation (mostly repression) affecting genes involved in cell cycle and cell growth, these being overrepresented in translationally regulated genes, providing a molecular framework for the arrest of cell proliferation following starvation. Starvation-induced translational control also affects chromatin regulation genes, such as the HD1 histone deacetylase, and the level of histone H4 acetylation was found to increase during starvation. This suggests that regulation of the global nuclear transcriptional activity might be linked to cytoplasmic translational regulations.

Abstract
The TOR (target of rapamycin) pathway is a phylogenetically conserved transduction system in eukaryotes linking the energy status of the cell to the protein synthesis apparatus and to cell growth. The TOR protein is specifically inhibited by a rapamycin–FKBP12 complex (where FKBP stands for FK506-binding protein) in yeast and animal cells. Whereas plants appear insensitive to rapamycin, Arabidopsis thaliana harbours a single TOR gene, which is essential for embryonic development. It was found that the product of this gene was capable of binding to rapamycin and yeast FKBP12. In-frame fusion with a GUS reporter gene shows that the TOR protein is produced essentially in proliferating zones, whereas the TOR mRNA can be detected in all organs suggesting a translational regulation of TOR. Phenotypic analysis of Arabidopsis TOR mutants indicates that the plant TOR pathway fulfils the same role in controlling cell growth as its other eukaryotic counterparts.

Abstract
A major 43 kDa protein from the protective tube of Riftia pachyptila (Vestimentifera), named RP43, was partly microsequenced after isolation by SDS/PAGE from the protein fraction of tubes collected around the hydrothermal vents at the East Pacific Rise. On the basis of the partial peptide sequences obtained, experiments using reverse-transcriptase-mediated PCR and rapid amplification of cDNA ends led to the complete cDNA sequence. Analysis of deduced amino acid sequence of RP43 showed the presence of CUB domains (100-110-residue-spanning domains first reported in the complement subcomponents C1r/C1s, epidermal-growth-factor-related sea urchin protein and bone morphogenetic protein 1) that seem to be involved in protein-protein and glycosaminoglycan-protein interactions. This peculiarity strongly suggests that RP43 might have a crucial role in tightening the different elements of the worm tube. However, the absence of chitin-binding motifs inclines us to favour a role in protein-protein interactions during assembly of the tube components. The RP43 mRNA was found to be present in specific epidermal cells from the worm body wall but never in the chitin-synthesizing gland cells. This unexpected result clearly indicates that the major tube protein is synthesized in specialized areas of the outer epithelium and that at least two different tissues are involved in the synthesis of the exoskeleton.

Abstract
Using a RT-PCR approach, the Tenebrio molitor homologue of Drosophila Ultraspiracle (TmUSP) was characterized. Its DNA binding domain shows a degree of identity with those of the other insect USPs. However, the ligand binding domain is closer to those of retinoid X receptors. Using an antibody raised against DmUSP, Western blot analysis of proteins from epidermis and other tissues revealed five immunoreactive bands, corresponding to different phosphorylated forms of a unique polypeptide, as shown by lambda-phosphatase treatment. The nuclear form of TmUSP seems unphosphorylated. An in vivo 20-hydroxyecdysone treatment increases considerably and rapidly the phosphorylated forms of TmUSP. This post-translational modification may play a role in the 20-hydroxyecdysone response.

Abstract
Five PCR fragments corresponding to a part of the DNA-binding domain of different hormone nuclear receptors were isolated from Tenebrio molitor mRNAs. The sequence identity of three of them with known Drosophila nuclear receptors strongly suggests that they are the Tenebrio orthologs of seven-up, DHR3 and beta-FTZ-F1, and thus named Tmsvp, TmHR3 and TmFTZ-F1. The full-length sequences of the other two were established. TmHR78 is either a new receptor of the DHR78 family or the same gene which has evolved rapidly, particularly in the E domain. TmGRF belongs to the GCNF1 family and its in vitro translated product binds to the extended half site TCAAGGTCA with high affinity. The periods of expression of the corresponding transcripts in epidermal cells during Tenebrio metamorphosis were analyzed as a function of 20-hydroxyecdysone titers measured in the hemolymph of the animals taken for RNA extraction. Comparison of the expression profiles of these nuclear receptors with those observed during Drosophila metamorphosis revealed similar temporal correlations as a function of ecdysteroid variations, which further supported the sequence identity data for TmSVP, TmHR3, TmFTZ-F1 and TmHR78.

Abstract
A 56-kDa polypeptide suspected to be the tanning hormone 'bursicon' was analyzed using the monoclonal antibody (mAb) 01C10 of Song and Ma. We studied the beetle Tenebrio molitor, for which data on bursicon have been recently published. After purification by two-dimensional gel electrophoresis of brain proteins, the immunoreactive 56-kDa polypeptide was trypsinated and microsequenced. The obtained sequences revealed a high homology with alpha- and beta-tubulins. In a complementary study, immunoreactive clones were isolated, using the 01C10 mAb, from a library in expression vector obtained from Drosophila melanogaster head cDNAs. Again, the isolated clones were found, after cDNA sequencing, to correspond to tubulin. Our results suggest that, although the 01C10 mAb could possibly still have a great affinity for a polypeptide present in very low quantities in a few brain neurosecretory cells, it also proved to have an artefactual affinity for a 56-kDa polypeptide, identified as tubulin, which is not involved in tanning control.
