Glycéronéogenèse et PEPCK-C

Un des liens entre obésité, résistance à l’insuline et diabète de type 2 incrimine les acides gras non estérifiés (AGNE) issus de l’hydrolyse des triglycérides dans le tissu adipeux. Une part importante de ces AGNE est ré-estérifiée immédiatement en triglycérides. La ré-estérification requiert la glycéronéogenèse ou synthèse de glycérol-3-phosphate qui, notamment à jeun, provient de substrats non glucidiques. Plus le recyclage des AGNE est important, moins ils sont libérés. La glycéronéogenèse et l’expression de son enzyme clé, la PEPCK-C, sont sélectivement induites par les thiazolidinediones hypolipidémiantes et antidiabétiques qui réduisent ainsi l’efflux des AGNE, leur taux circulant et l’insulinorésistance

Erratum: New neighbours: IV. 30 DENIS late-M dwarfs between 15 and 30 parsecs

International audienceIn the printing process of the paper: ``New neighbours: IV. 30 DENIS late-M dwar fs between 15 and 30 parsecs" by N. Phan-Bao et~al., A&A 380, 590 (2001), the symbol ``arcsec yr-1" was unfortunately shortened to: ``yr-1"

A large sample of ultracool dwarfs with DENIS

International audienceWe will present a large sample of 300 very late M and L dwarfs, identified by analysing 5700 square degrees of DENIS data. The sample is complete for objects redder than I-J=3.0 (M8) and brighter than I=18, and thus statistically well defined. It is an excellent basis for studies of the disk population of very low mass stars and brown drawfs, allowing clean determinations of the luminosity function, mass function, and multiplicity statistics
