What this meansNAGLU has been experimentally perturbed in HepG2 cells, but it has not been independently perturbed in a DMD muscle model. Different DMD datasets do not completely agree on its disease-associated direction. The next useful step is risk/context review—not a therapeutic claim.
通俗解释NAGLU已经在HepG2细胞中做过扰动，但尚未在DMD肌肉模型中独立验证。不同DMD数据集对它的疾病相关方向并不完全一致。下一步应完成能弥补当前证据缺口的受控实验，而不能把它直接称为治疗靶点。

Dataset-level evidence for NAGLU
Every row keeps its original context, metric and denominator. Empty fields remain explicit; no cross-source meta-effect is computed.

Measured HepG2 response is compared with three separately measured DMD pathway axes. Individual source results come first; pooled values are exploratory descriptive summaries only.

Cross-context projection is not a measured NAGLU response in DMD muscle and does not establish rescue, efficacy, or a target rank.

Why the workflow abstains
- weak split half measurement
- moderate dependency caution
- disease source projection inconsistent
Pathways overlap and the three source vectors are not independent studies. HepG2 cell-level statistics support source-context exploration only. The disease-matched functional-validation gate remains open.
What this candidate is for
Does NAGLU have a dependency, toxicity or context-specific safety profile that blocks escalation?
A candidate record authorizes a bounded question and next experiment. It does not authorize a therapeutic or clinical claim.
How would the result change the decision?
SupportiveAdvance to a functional muscle assay only if a reproducible window passes engagement and viability gates.
NullStop escalation and retain the negative feasibility evidence if no acceptable window remains.
Inconclusive / QC failureClassify a donor-, dose- or reagent-specific window as context dependent and redesign first.

Readiness upgrade requiredRun an independent DMD/control myogenic perturbation with predeclared molecular, state and functional endpoints.
The decision-blocking gap is the next missing layer that prevents the current action from advancing. The highest missing layer is the longer-term evidence ceiling; it is not necessarily the next experiment.
