Introduction La fonction et la survie des îlots de Langerhans de rat sont optimales après culture en présence de 10 mM de glucose (G10) et sont altérées par les basses comme par les fortes concentrations de glucose. Afin de mieux comprendre les mécanismes moléculaires sous-jacents aux altérations phénotypiques des cellules b par le glucose, nous avons mesuré les niveaux d’expression de l’ensemble des ARNm dans les îlots de rat précultivés une semaine en G10, et ensuite cultivés 18h en G2, G5, G10 et G30 (Affymetrix Rat Genome 230 2.0 oligonucleotide arrays, n=4). Résultats Parmi les 31099 probe sets présents sur les bio-puces, 15910 ont été détectés dans au moins une concentration de glucose. Ensuite, les probe sets significativement modif...
