Pharmacological Chaperones for GCase that Switch Conformation with pH Enhance Enzyme Levels in Gaucher Animal Models
Bibliographic record
Abstract
Gaucher disease is a lysosomal storage disorder caused by mutations which destabilize the native folded form of GCase, triggering degradation and ultimately resulting in low enzyme activity. Pharmacological chaperones (PCs) which stabilize mutant GCase have been used to increase lysosomal activity through improving trafficking efficiency. By engineering their inherent basicity, we have synthesized PCs that change conformation between the ER and the lysosomal environment, thus weakening binding to GCase after its successful trafficking to the lysosome. NMR studies confirmed the conformational change while X-ray data reveal bound conformations and binding modes. These results were further corroborated by cell studies showing increases in GCase activity when using the pH-switchable probe at low dosing. Preliminary in vivo assays with humanized mouse models of Gaucher showed enhanced GCase activity levels in relevant tissues, including the brain, further supporting their potential.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
