Spatial sequestration and detoxification of Huntingtin by the ribosome quality control complex.

abstract：:Tumors are composed of many different cell types including cancer cells, fibroblasts, and immune cells. Dissecting functional metabolic differences between cell types within a mixed population can be challenging due to the rapid turnover of metabolites relative to the time needed to isolate cells. To overcome this cha...
