     Quick Analysis Plan



    Of the five supplied papers, the two mechanistic studies most plausibly attributable to Weidong Le (the LDOC1 EGFR-trafficking paper and the CIN85 phosphorylation paper) show strong internal quantitative controls but clear rigor gaps: reliance on 1–2 EGFR-mutant cell lines, no in vivo validation, and in one case undisclosed statistical detail for key IC50 comparisons ().


     Long Analysis Plan



    Attribution caveat first

    The supplied records contain full-text content but no author lists. Weidong Le is documented in the literature as an EGFR-endocytosis researcher, yet authorship cannot be confirmed from these records alone β€” a blind spot BGPT will not paper over. The two papers below are the best-supported candidates; the analysis critiques rigor from full text only.

    1. LDOC1–clathrin adaptor paper (IJMS 2024): quantitatively rich, causally incomplete

    Controls: Four cell lines spanning EGFR WT (A549, U2OS) and EGFR-mutant (PC9, HCC827) provide an internal isogenic contrast; co-IP, biotinylation endocytosis assays, and rescue-style overexpression (LDOC1-V5) are appropriately triangulated ().
    Statistics: IC50 shifts are the weakest link β€” PC9 gefitinib IC50 "increased" with exact values unavailable in text; only HCC827 reports numbers (1.8 β†’ 2.3 Β΅M, a modest ~28% shift) and osimertinib shows no change (0.9 Β΅M), a useful internal specificity control. The clinical association is strong (p < 0.001, n = 100 gefitinib-treated) but retrospective and univariate β€” no multivariable adjustment is reported ().
    Reproducibility: Supplementary materials and software versions are documented; "no new data created" limits raw-data sharing. No independent shRNA validation or xenograft model β€” falsification therefore rests on untested shRNA off-targets.

    Figure: Cytoplasmic EGFR frequency by LDOC1 status in the 200-patient IHC cohort β€” the paper's strongest quantitative clinical signal, reproduced directly from reported values.

    2. CIN85 phosphorylation paper (MBoC 2012): the most rigorous of the set

    Controls: The phospho-defective CIN85-4F mutant preserves Src binding (a critical structural-equivalence control), and SYF triple-kinase MEFs plus Src re-expression (3–4Γ— degradation acceleration) form a genuine epistasis chain β€” kinase β†’ phosphorylation β†’ c-Cbl binding β†’ ubiquitination β†’ MVB sorting β†’ degradation ().
    Statistics: Reported p-values are specific (p < 0.0005, p < 0.0001) and β‰₯30 cells per condition were quantified β€” unusually transparent for trafficking microscopy. Gaps: Overexpression-only systems, four simultaneous Yβ†’F substitutions (structure not checked), ~20–60 min observation windows, and no data-sharing statement ().

    The other three records are not rigor-testable

    The SISH screening study (n = 96) has high reproducibility scores but only 10 patient-level rows were extracted; the JTO 2017 abstract has zero references and no numerical IC50 data; the EGFR-landscape review generates no primary evidence. None support a rigorous full-text verdict ().

    Verdict and what would change it

    Confidence: moderate. The CIN85 study is the most rigorously controlled; the LDOC1 study is mechanistically detailed but underpowered on in vivo causality and statistical reporting. What would falsify or upgrade the verdict: (1) author-list confirmation that Weidong Le did or did not author these records; (2) raw IC50 dose-response curves from the LDOC1 study; (3) multi-shRNA rescue or CRISPR knockout reproducing the LDOC1 phenotype; (4) independent replication of CIN85-4F in a non-overexpression, genome-edited setting.

     Hypothesis Graveyard



    EGFR copy number predicts mutation status in lung adenocarcinoma: falsified by the SISH study showing low sensitivity and PPV despite a statistically significant association (n=96).


    EGFR gene copy number and protein overexpression are robust predictive biomarkers: the 2011 review documents inconsistent predictive value across studies, undermining this once-prevalent hypothesis.
