YAP/TFEB pathway promotes autophagic cell death and hypertrophic cardiomyopathy in lysosomal storage diseases
Bibliographic record
Abstract
Lysosomal storage disorders (LSD) are a group of inherited metabolic diseases characterized by lysosomal enzyme deficiency. The cardiac phenotype includes cardiomyopathy with eventual heart failure. Lysosome-mediated degradation processes, such as autophagy, maintain cellular homeostasis by discarding cellular debris and damaged organelles. Under stress, the transcription factor EB (TFEB) moves into the nucleus to activate transcription of lysosome biogenesis and autophagic proteins. In this issue of the JCI, Ikeda et al. report on their exploration of the signaling pathway involved with regulating lysosomal proteins specifically in the heart. The researchers generated a mouse model for LSD that was restricted to cardiac tissue. Unexpectedly, modulation of TFEB alone was insufficient to fully rescue the underlying clearance defect in lysosomal-associated disorders. The authors identified the Yes-associated protein (YAP)/TFEB signaling pathway as a key regulator of autophagosomes. These findings suggest that undigested autophagosomes accumulate and result in the cell death and cardiac dysfunction observed with LSD.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
