Springer Foreword The Saint-Flour Probability Summer School was founded in 1971. It is supported by CNRS, the " Ministère de la Recherche " , and the " Université Blaise Pascal ". Three series of lectures were given at the 35th School (July 6–23, 2005) by the Professors Doney, Evans and Villani. These courses will be published separately , and this volume(More)
Human intestinal Caco-2 cells were used to examine the expression of fibronectin (FN) and laminin (LN) during enterocytic differentiation. Combination of immunoprecipitation, Western and Northern blotting revealed that Caco-2 cells expressed a classical FN and a variant form of LN: besides B1 and B2 chains, LN contained a 350-kDa heavy chain instead of the(More)
All-trans retinoic acid (RA) has been shown to enhance subepidermal repair in photoaged hairless mice. The current study assesses the effects of RA on the glycosaminoglycan (GAG) content in irradiated and nonirradiated mouse skin. Mice were exposed to ultraviolet B (UVB) for 10 wk, after which they were treated either with 0.05% RA or with an(More)
In this report, we investigated the expression of annexins I, II, V, and VI by Northern and Western blot analysis in four cell lines isolated from human fetal tracheae. Two cell lines were obtained from normal fetuses and the two others from fetuses with cystic fibrosis (CF). One CF fetus was heterozygous for the S549N and N1303K substitutions, whereas the(More)
To investigate whether glycanic chains of prolactin receptors (PRL-R) play a role in hormone binding activity, comparison was made of rat and mouse liver solubilized receptors with respect to both their affinity for the hormone and their glycosylation properties. As compared with rat receptors, mouse receptors exhibited a 2-fold higher affinity for human(More)
We previously reported that Chinese hamster ovary (CHO) cell lines overexpressing mutated human insulin receptors (hIRs) in which the tyrosine residues 1162 and 1163 were replaced by phenylalanines (CHO-Y2) exhibited a marked defect in hormone-induced receptor internalization as compared to CHO transfectants overexpressing wild-type hIRs (CHO-R). These two(More)
We demonstrate that in immortalized normal human tracheal epithelial cells (NT-1 and 56FHTE8o-) 14C-labeled glycoconjugate secretion may be regulated independently by agonists of the protein kinase A (PKA) and protein kinase C (PKC) signaling pathways. In contrast, in immortalized cystic fibrosis (CF) human tracheal epithelial cells (CFT-1 and CFT-2),(More)
The genomic sequence on mouse Chromosome (Chr) 2 corresponding to a previously identified novel cDNA has been characterized. The genomic organization of this locus, adjacent to the beta 2 microglobulin gene, has the properties of a processed gene or retroposon including the presence of a short flanking direct repeat, a polyadenylation signal/poly A tract,(More)
We have previously shown that fibroblasts from patients with cystic fibrosis (CF) display a higher response to 4 beta-phorbol 12-myristate 13-acetate (PMA) than control fibroblasts for stimulation of both protein kinase C (PKC) cytosol-to-membrane translocation and glycoconjugate secretion. In this study we took advantage of these cells with differential(More)
