CONFOCAL analysis of early postnatal auditory neurones in a bicompartmental culture system was used to test for chemoattractant properties of NGF, BDNF and NT-3 on neuronal process outgrowth. NT-3 exerted a strong tropic effect on neuritic outgrowth from auditory neurones in this system. BDNF and NGF did not have any tropic activity that directed processes outgrowth from auditory neurones. However, BDNF was important for the support of neuronal survival in NGF-treated cultures and for neuritogenesis in NT-3-treated cultures. Since NT-3 has been identified as both a survival factor and a chemotropic agent for auditory neurones, it is likely that this neurotrophin will be a useful therapeutic agent in the treatment of damaged cochleae for the recovery of hearing.

The theory of the nth order moment W(n)D of a P Cygni line profile due to a resonance doublet line transition is developed here in the framework of the Sobolev approximation. It is shown that, in the optically thick approximation, the asymptotic value W(n)D,t is entirely dependent on both the doublet separation and the type of the velocity field characterizing the expanding atmosphere. The most useful P Cygni profiles seem to be those which are unsaturated. [less ▲]

Many reintroduction projects for conservation fail, and there are a large number of factors that may contribute to failure. Genetic analysis can be used to help stack the odds of a reintroduction in favour of success, by conducting assessment of source populations to evaluate the possibility of inbreeding and outbreeding depression and by conducting postrelease monitoring. In this study, we use a panel of 306 SNP (single nucleotide polymorphism) markers and 487-489 base pairs of mitochondrial DNA control region sequence data to examine 321 individuals from possible source populations of the Eurasian beaver for a reintroduction to Scotland. We use this information to reassess the phylogenetic history of the Eurasian beavers, to examine the genetic legacy of past reintroductions on the Eurasian landmass and to assess the future power of the genetic markers to conduct ongoing monitoring via parentage analysis and individual identification. We demonstrate the capacity of medium density genetic data (hundreds of SNPs) to provide information suitable for applied conservation and discuss the difficulty of balancing the need for high genetic diversity against phylogenetic best fit when choosing source population(s) for reintroduction. © 2014 The Authors.

We studied the fine structural organization of nuclear bodies in the root meristem during germination of maize and Arabidopsis thaliana using electron microscopy (EM). Cajal bodies (CBs) were observed in quiescent embryos as well as germinating cells in both species. The number and distribution of CBs were investigated. To characterize the nuclear splicing domains, immunofluorescence labelling with antibodies against splicing factors (U2B" and m3G-snRNAs) and in situ hybridisation (with U1/U6 antisense probes) were performed combined with confocal microscopy. Antibodies specific to the Arabidopsis SR splicing factor atRSp31 were produced. AtRSp31 was detected in quiescent nuclei and in germinating cells. This study revealed an unexpected nuclear speckled organization of atRSp31 in root epidermal cells where micro clusters of interchromatin granules were also observed by EM. Therefore, we examined the distribution of green fluorescent protein (GFP)-tagged atRSp31 in living cells after Agrobacterium-mediated transient expression. When expressed transiently, atRSp31-GFP exhibited a speckled distribution in leaf cells. Treatments with -amanitin, okadaic acid, staurosporine or heat-shock induced the speckles to reorganize. Furthermore, we have generated stable Arabidopsis transgenics expressing atRSp31-GFP. The distribution of the fusion protein was identical to the endogenous atRSp31. Three-dimensional time-lapse confocal microscopy showed that speckles were highly dynamic domains over time. [less ▲]

The purpose of this study is to propose a suitable vector combining increased circulation lifetime and intracellular delivery capacities for a therapeutic peptide. Long circulating classical liposomes [SPC:CHOL:PEG-750-DSPE (47:47:6 molar% ratio)] or pH-sensitive stealth liposomes [DOPE:CHEMS:CHOL:PEG(750)-DSPE (43:21:30:6 molar% ratio)] were used to deliver a therapeutic peptide to its nuclear site of action. The benefit of using stealth pH-sensitive liposomes was investigated and formulations were compared to classical liposomes in terms of size, shape, charge, encapsulation efficiency, stability and, most importantly, in terms of cellular uptake. Confocal microscopy and flow cytometry were used to evaluate the intracellular fate of liposomes themselves and of their hydrophilic encapsulated material. Cellular uptake of peptide-loaded liposomes was also investigated in three cell lines: Hs578t human epithelial cells from breast carcinoma, MDA-MB-231 human breast carcinoma cells and WI-26 human diploid lung fibroblast cells. The difference between formulations in terms of peptide delivery from the endosome to the cytoplasm and even to the nucleus was investigated as a function of time. Characterization studies showed that both formulations possess acceptable size, shape and encapsulation efficiency but cellular uptake studies showed the important benefit of the pH-sensitive formulation over the classical one, in spite of liposome PEGylation. Indeed, stealth pH-sensitive liposomes were able to deliver hydrophilic materials strongly to the cytoplasm. Most importantly, when encapsulated in pH-sensitive stealth liposomes, the peptide was able to reach the nucleus of tumorigenic and non tumorigenic breast cancer cells. [less ▲]

Histone deacetylase 7 (HDAC7) is a T-cell receptor (TCR) signal-dependent regulator of differentiation that is highly expressed in CD4/CD8 double-positive (DP) thymocytes. Here, we examine the effect of blocking TCR-dependent nuclear export of HDAC7 during thymic selection, through expression of a signal-resistant mutant of HDAC7 (HDAC7-DeltaP) in thymocytes. We find that HDAC7-DeltaP transgenic thymocytes exhibit a profound block in negative thymic selection, but can still undergo positive selection, resulting in the escape of autoreactive T cells into the periphery. Gene expression profiling reveals a comprehensive suppression of the negative selection-associated gene expression programme in DP thymocytes, associated with a defect in the activation of MAP kinase pathways by TCR signals. The consequence of this block in vivo is a lethal autoimmune syndrome involving the exocrine pancreas and other abdominal organs. These experiments establish a novel molecular model of autoimmunity and cast new light on the relationship between thymic selection and immune self-tolerance. [less ▲]

Anthracycline drugs are widely used for the treatment of solid tumors and leukemia, but the molecular basis of their biological effect is still poorly understood. In the HCT116 colon carcinoma cell line, which retains a wild-type inducible p53 gene, we show that the anthracycline daunomycin is a potent inducer of p53 and NF-kappaB transcription factors. Nuclear accumulation of p53 protein occurred because of increased protein stability and enhanced gene expression. In addition, daunomycin induced the p53 promoter through the binding of p50/p65 NF-kappaB heterodimers to the kappaB site in the p53 promoter. Under our conditions, the free radical scavengers NAC and PDTC were not able to block NF-kappaB activation or p53 induction, indicating that reactive oxygen intermediates were not involved in the cellular response to daunomycin stimulation. Overexpression of a stable unresponsive IkappaBalpha mutant in HCT116 cells resulted in a complete inhibition of the NF-kappaB activation but only a partial impairment of the p53 protein accumulation induced by daunomycin. We conclude that the p53-activating signal generated by daunomycin is partially regulated by NF-kappaB. [less ▲]
