The effects of various muscarinic antagonists on acetylcholine (ACh)-induced pulmonary oedema were studied in isolated perfused rabbit lungs. ACh induced a dose-dependent increase in the capillary filtration coefficient (Kf,c). This effect has been previously related to the activation of the capsaicin-sensitive nerve fibres and the release of substance P. Atropine, pirenzepine (M1-selective antagonist) and 4-DAMP (M3-selective antagonist) altered this response, producing a dose-dependent shift to the right of the ACh concentration-Kf,c response curve. By contrast, the M2-selective antagonist AFDX-116 shifted the ACh concentration-response curve to the left. Atropine, pirenzepine and 4-DAMP also significantly reduced the capsaicin-induced increase in the Kf,c, while AFDX-116 enhanced it. We conclude that multiple muscarinic receptor subtypes are present in the rabbit lung, located on the C-fibres, and are involved in the ACh-induced pulmonary oedema. M1 and M3 receptors seem to stimulate the release of neuropeptides from C-fibres, whereas M2 receptors have an inhibitory effect on these fibers. [less ▲]

A one year old girl, born to consanguineous parents, presented with unexplained liver disease. Liver biopsies revealed respiratory chain complex I and IV deficiencies. Progressive liver failure at 19 months led to liver transplantation. One year later, anemia and thrombocytopenia occurred due to hypersplenism. Histopathological analyses of partial splenectomy showed the presence of Gaucher cells, and Gaucher disease was confirmed by enzyme and genetic analyses. Respiratory chain deficiency was considered as a possible artifact due to liver failure and cirrhosis. She was treated by ERT. Clinical follow-up showed developmental delay, strabism, nystagmus and external ophthalmoplegia. A mitochondrial disorder was considered again, and molecular analysis revealed a mtDNA depletion syndrome due to homozygous MPV17 mutation. In the meantime, a young sister presented with acute abdominal pain, pancytopenia and major hepatosplenomegaly. ERT for Gaucher disease allowed visceral normalization, without any developmental delay or neurological symptom. She was unaffected by the mtDNA depletion syndrome. Unfortunately, a third sister systematically screened, was affected by both conditions. Despite ERT, she presents chronic moderate liver dysfunction and mild hepatomegaly. Aged 3 years, she has marked developmental delay and ophthalmoplegia. Metabolic investigations showed normal blood lactate, in basal condition as well as following an oral glucose load [less ▲]

Pregnancy-associated glycoprotein (PAG)-1 (PAG1) and pregnancy-specific protein B are either identical or closely related antigens released by trophoblast binucleate cells of placentas of cattle. Sheep and other ruminants produce similar products. There is evidence, however, that these antigens, which are related structurally to the pepsinogens and other aspartic proteinases, are not single gene products but members of an extensive family. Here, the sequential use of ammonium sulfate precipitation and Sepharose blue, anion-exchange, and cation-exchange chromatographies, as well as isoelectric elution from a Mono P column, has allowed several PAG1-related molecules to be purified from the medium after culture of explants from Day 100 sheep placentas. Each of these PAGs cross-reacted to a varying extent with a panel of three different anti-PAG1 antisera. Four of them, all of which were major secretory products of the placenta, were subjected to amino-terminal microsequencing. Although each was related to ovine (ov) PAG1, none was identical. Reverse transcription-polymerase chain reaction was then used to amplify PAG1-related cDNA from Day 100 placental RNA. Seven novel full-length cDNA, all distinct from ovPAG1, were identified from 25 cDNA selected for sequencing. Only two of these (ovPAG3 and ovPAG7) encoded polypeptides identical in sequence at their inferred amino termini to one of the PAGs (ovPAG65) purified from explant cultures. Even so, they were only 84% identical in overall sequence. The remaining five cDNA were unique. In situ hybridization analysis revealed that expression of ovPAG3 and ovPAG7, like that of ovPAG1, is confined to trophoblast binucleate cells. The data confirm that at Day 100 of pregnancy the ovine placenta produces many different PAGs, which differ considerably in sequence and immunological cross-reactivity. [less ▲]

The well-known Rel/NF-kappaB family of vertebrate transcription factors comprises a number of structurally related, interacting proteins that bind DNA as dimers and whose activity is regulated by subcellular location. This family includes many members (p50, p52, RelA, RelB, c-Rel, ...), most of which can form DNA-binding homo- or hetero-dimers. All Rel proteins contain a highly conserved domain of approximately 300 amino-acids, called the Rel homology domain (RH), which contains sequences necessary for the formation of dimers, nuclear localization, DNA binding and IkappaB binding. Nuclear expression and consequent biological action of the eukaryotic NF-kappaB transcription factor complex are tightly regulated through its cytoplasmic retention by ankyrin-rich inhibitory proteins known as IkappaB. The IkappaB proteins include a group of related proteins that interact with Rel dimers and regulate their activities. The interaction of a given IkappaB protein with a Rel complex can affect the Rel complex in distinct ways. In the best characterized example, IkappaB-alpha interacts with a p50/RelA (NF-kappaB) heterodimer to retain the complex in the cytoplasm and inhibit its DNA-binding activity. The NF-kappaB/IkappaB-alpha complex is located in the cytoplasm of most resting cells, but can be rapidly induced to enter the cell nucleus. Upon receiving a variety of signals, many of which are probably mediated by the generation of reactive oxygen species (ROS), IkappaB-alpha undergoes phosphorylation at serine residues by a ubiquitin-dependent protein kinase, is then ubiquitinated at nearby lysine residues and finally degraded by the proteasome, probably while still complexed with NF-kappaB. Removal of IkappaB-alpha uncovers the nuclear localization signals on subunits of NF-kappaB, allowing the complex to enter the nucleus, bind to DNA and affect gene expression. Like proinflammatory cytokines (e.g. IL-1, TNF), various ROS (peroxides, singlet oxygen, ...) as well as UV (C to A) light are capable of mediating NF-kappaB nuclear translocation, while the sensor molecules which are sensitive to these agents and trigger IkappaB-alpha proteolysis are still unidentified. We also show that a ROS-independent mechanism is activated by IL-1beta in epithelial cells and seems to involve the acidic sphingomyelinase/ceramide transduction pathway. [less ▲]

We are interested in investigating the function of Hoxc8 in skeletogenesis during mouse development. Previous studies have shown that deregulation of Hoxc8 expression in the mouse leads to several skeletal defects, such as homeotic transformation in the thoracic vertebrae, abnormal development of the rib cage, and overproliferation of chondrocytes in the hypertrophic area. By deleting a crucial enhancer of Hoxc8 in vivo, we found that precise temporal expression of Hoxc8 is important for determining the correct identity of the vertebral column in early embryos. We also identified downstream targets of Hoxc8 relevant to osteoblast differentiation at later developmental stages. [less ▲]

We explore the complex dynamics of a non-coalescing drop of moderate size inside a circular hydraulic jump of the same liquid formed on a horizontal disk. In this situation the drop is moving along the jump and one observes two different motions: a periodic one (it orbits at constant speed) and an irregular one involving reversals of the orbital motion. Modeling the drop as a rigid sphere exchanging friction with liquid across a thin film of air, we rationalize both the orbital motion and the internal rotation of the drop. This internal rotation is evidenced by tracer visualization and exhibits an unexpected dependence upon drop size. [less ▲]
