1 Chloroquine extends the lifetime of the activated insulin receptor complex in endosomes. Chloroquine insulin receptor Rattus norvegicus
2 Chloroquine treatment also increased the insulin receptor content of endosomes after insulin injection (integrated over 0-45 min) by 31% when compared with controls (p < 0.05). Chloroquine insulin receptor Rattus norvegicus
3 Similarly, chloroquine increased both insulin receptor phosphotyrosine content and its exogenous tyrosine kinase activity after insulin injection (64%; p < 0.01 and 96% and p < 0. Chloroquine insulin receptor Rattus norvegicus
4 These observations are consistent with the hypothesis that chloroquine-dependent inhibition of endosomal insulin receptor dissociation and subsequent degradation prolongs the half-life of the active endosomal receptor and potentiates insulin signaling from this compartment. Chloroquine insulin receptor Rattus norvegicus
