Elevated temperature produces cystine depletion in cystinotic fibroblasts.
Increasing the incubation temperature of cystinotic fibroblasts to 40 or 43 degrees C produces a 70-80% decrease in lysosomal cystine content within 24-48 h. This effect is probably mediated by an altered substrate affinity for another lysosomal transport protein.
