Adaptation du métabolisme respiratoire de l'huître creuse Crassostrea gigas
Provedor de dados: 5
Autores: Le Moullac, Gilles.
Summer mortality of the oyster result from the interaction of many factors. A respiratory assumption proposes a link between the supposed causes of the energy state, the cultivation methods and the medium. This work is focused towards the search for specific metabolic markers of environmental stresses. The cDNA of genes coding for PK and PEPCK were cloned and sequenced in order to detect their regulation level. The sediment nearness affects the state of energy reserves, the metabolic pathways of energy production implying a regulation of the PK. Face to the dissolved oxygen decline, oysters were oxyregulator but with a low regulation ability. In hypoxia, glycolysis was slowed down. PK activity was inhibited resulting from an increase in alanine sensitivity...

Apport des informations moléculaires et cellulaires pour la caractérisation de la résistance de l'huître plate européenne vis-à-vis de la bonamiose, et pour la détection de signatures de la sélection naturelle

The European flat oyster, an endemic species from European coasts, has been classified in the category of "endangered and/or declining species" since 2003. Indeed, the natural beds of this oyster, consumed since ancient times, have gradually been decimated by over-exploitation and by successive emergence of parasitic diseases. The parasite that causes the disease called bonamiosis has contributed to drastically reduce the French and European aquacultural production of flat oyster. Marine bivalve molluscs display two specificities that restrict possibilities to fight against diseases: they are grown in an open environment, and possess an innate immune system lacking in adaptive response. In this context, the selection of animaIs naturally resistant to...

Etude de nouvelles cibles moleculaires de cancer bronchopulmonaire non a petites cellules pharmacomodulées par des substances originales naturelles et synthetiques
Provedor de dados: 5
Autores: Moreau, Dimitri.
Still rare disease at the beginning of the 20th century, the lung cancer is at the origin of more than 6 % of the deaths in France currently. It occupies there the first rank of the deaths by cancer whereas France is regarded as a country at the average risk among the Western countries. The discovery of new anti-cancer treatments increasingly more effective and specific, is thus today of primary importance.  The validation of the capacity of a molecule to being able to inhibit the cancerous proliferation, passes by several stages of tests starting with the description of an activity at the cellular level. One of the strategies used for the discovery of new compounds antiproliferativs, passes by an investigation of the bioactiv potential of a great number...
