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 ▲]

This paper reports a geochemical study of oceanic clays. Major and trace elements were analyzed on smectite-rich, clay size (<2 mu m) samples, bulk sediments, and leachate residues from the Central Indian Basin. Sr-Nd isotopes were also studied to investigate their geochemical evolution during transport in the water column, sedimentation, and diagenesis. The region is of special interest because the sedimentation records the interaction between the detrital supply from the Bengal Fan in the north and the biosiliceous input associated with the equatorial divergence in the south. The clay size fractions display extremely variable trace element contents, e.g., [Ba] = 100-5000 ppm, [Sr] = 20-200 ppm, Ce/Ce* = 0.9-3.3, [Nd] = 10-50 ppm. Although in the argillaceous samples, clay size fractions have a similar trace element imprint to the bulk sediment, some major fractionations occur in the biosiliceous samples between the clay and the bulk sediment, especially for Sr and rare earth elements (REE). Three major components may account for the variable geochemical signatures of these pelagic clays. The first component (component A), already identified by Fagel et al. (1994), is characterized by a homogeneous geochemical signature (La-N/Yb-N = 1.03-1.05; Th/Ta = 12.8-21.1; Ba/Th similar to 28) and a nonradiogenic Nd isotopic composition (Nd-143/Nd-144 similar to 0.511880): it traces a detrital Himalayan-derived origin. The two other components display a seawater-derived isotopic composition with global Sr (Sr-87/Sr-86 similar to 0.709060) and regional Indian Ocean Nd(Nd-143/Nd-144 similar to 0.512200) signatures. Both components are enriched in Sr and Ba (Sr similar to 150 ppm, Ba/Th similar to 500), and they are either enriched in light rare earth elements (LREE, e.g., Nd similar to 50 ppm) in the argillaceous sediments (component B) or LREE-depleted (Nd < 20 ppm) in the biosiliceous sediments (component C). The frequent occurrence of micrometric (<5 mu m) Sr-REE-Th enriched barite grains showing three major habits (rhombic, rounded, dendritic) suggests that these biologically-derived mineral phases had a major role in the genesis of components B and C. A strong clay-barite equilibration is deduced from the Post Archean Australian Shales PAAS-like REE patterns of these barites and the Ba enrichment of the clays. We suggest that it results from two successive mechanisms of exchange. First, at the top of the oxygen minimum zone, the microbial-induced decay of organic matter is proposed to trigger a series of trace element transfers between the various particulate-forming components (clays, barites, and decaying organic coatings). This is proposed as the origin of the clay component B: the barite-derived components (Ba, Sr) and the organic-derived positive Ce anomaly are imported to the clay particles while the PAAS signature of the clays is retained by the remaining barite crystals. Second, after settling, the barites are believed to partly dissolve and recrystallize, especially in the anoxic part of the sedimentary column. This diagenetic barite dissolution is proposed as the origin of the clay component C. Copyright (C) 1997 Elsevier Science Ltd. [less ▲]

Multiple sources in the copularization of become This paper shows how general productivity (see Barðdal 2009: 38) of the copular function of the verb become abruptly followed when a pre-copular stage had reached a threshold value about 1150, prior to which become only occurred with a spatial sense ‘arrive’, and with extensions of this sense. It is argued that this abrupt switch to general productivity rather than a gradual increase in productivity results from the fact that copular become is not the end result of a single diachronic lineage of constructions (i.e. a simple grammaticalization process, see Croft 2000: 32-37), but instead resulted from an interaction between lineages, as well as external influence, and from the coming together of all factors involved in the twelfth century. First, certain constructions in which become occurred gradually changed and interacted with each other. In a first stage, two constructions developed (through metaphor) out of become ‘arrive’. These are the constructions in (1), with a human subject and become meaning ‘attain’, and in (2), with an inanimate subject, a dative experiencer and become meaning ‘come upon’. (1) Heo becom to soþum wisdome. ‘She attained to true wisdom.’ (2) Seo þearlwisnis þæs heardan lifes him becwom. ‘The austerity of life came upon him.’ In a second stage a two-participant resultative construction, as in (3), developed as a syntactic blend of (1) and (2) (cf. De Smet 2009: 1747), which provided a formal template for a one-participant prepositional copular construction as in (4). (3) Andetnysse him becumeð to hæle ‘Confession results (for him) in salvation’ (4) Þii fader bi-com to one childe ‘Your father turned into a child.’ Another, unrelated construction provided a formal template for the adjectival copular construction. This is the depictive construction given in (5), in which an adjective serves as a secondary predicate, but become does not have a linking function (is not a copula). (5) He gesund becom to Æðelingege. ‘He arrived (and was) safe at Æðelinge.’ Second, the already existing copula weorðan ‘become’ (see Petré & Cuyckens 2009) provided a template of general productivity upon which the resultative construction could graft once it had become semantically sufficiently similar to a copular construction, and, once the copular stage was reached, the depictive construction also started to serve as a formal input for this analogical process, with as a result adjectival and nominal copular constructions. Finally, Old French probably also contributed (though only as a strengthening factor) to the success of copular become in precisely the twelfth century. From a balanced explanation taking into account all of these factors it is concluded that the sudden emergence of copular becuman is not as catastrophic as it at first seemed.
