Description of SAG

SAG (agoniste lisse) est un agoniste efficace du récepteur Smo. SAG acive la voie de signalisation Hedgehog. SAG induit fortement l'expression de la luciférase dans les cellules Shh - LIGHT2, avec une EC50 est 3nm. Dans les cellules Cos-1 qui expriment Smo, SAG a un Kd de 59nM pour le complex SAG/Smo[1-3].

SAG (250nM; 24h) promeut la migration des cellules MDA - MB - 231[4]. Le traitement de SAG(1μM; 6 jours) corrige le dysfonctionnement mitochondrial dans les astrocytes FXN-déficients [5].

SAG(15-20mg/kg;ip) induit généralement une polydactylie préaxiale de manière de la dose - dépendante dans les rats[6]. SAG(20μg/g de poids corporel; i.p; 3 fois) restaure la signalisation Shh (Sonic hedgehog) qui permet de corriger la fonction de BBB des rats humanisés HIV-infectés[7].

Protocol of SAG

Expériences cellulaires [1]:

Lignées cellulaires

Cellules MDAMB 231

Méthode de préparation

Les cellules ont été ensemencées à la concentration de 2 × 10cellules dans les plaques à 12 puits. Lorsqu'elles ont été traitées par les composés, les cellules ont été prétraitées pendant 24 heures par SAG de 250nM ou DMSO en tant que témoin. Le lendemain, une égratignure a été effectuée par utiliser une pipette p200 sur une monocouche confluente; les cellules ont ensuite été lavées par PBS et remises en suspension dans 1ml RPMI supplémenté par 10% FBS et AraC (cytosine β-D-arabinofuranoside; un inhibiteur sélectif de la synthèse de DNA; 2.5µg/ml).

Conditions de réaction

250nM;24h

Domaines d'application

SAG promeut la migration des cellules MDA-MB-231.
Expériences animales [2]:

Modèles animaux

Rats humanisés HIV-infectés

Méthode de préparation

Les rats ont été injectés tous les deux jours par SAG (20μg/g de poids corporel) ou un témoin véhicule, DMSO, pour un total de 3 injections. Un essai d'exclusion du bleu d'Evans a été effectué pour mesurer la perméabilité de BBB.

Forme de dosage

20μg/g de poids corporel; i.p; 3 fois

Domaines d'application

SAG restaure l'intégrité de BBB (barrière hémato-encéphale).
