     Quick Answer


    Ferroptosis ↔ keratinocytes ↔ psoriatic inflammation: evidence map (from the provided raw-paper extraction)
    Given the single supplied study, the most defensible “evidence map” is: keratinocyte ferroptosis signatures in psoriasis (↑ACSL4/PTGS2/TFRC, ↓GPX4/FTL/FTH1; ↑lipid peroxidation marker 4-HNE) co-occur with lipid-oxidation pathway activity linked to Th22/Th17, and ferroptosis inhibition reduced IMQ-induced psoriasiform dermatitis severity and keratinocyte inflammatory outputs.

     Long Answer


    Meta-analysis (evidence map) request
    You asked for a “Meta-analysis: Jinhua Xu ferroptosis psoriasis evidence map”. However, only one primary study was provided in the research data, so I cannot compute a true quantitative meta-analysis across multiple studies without additional paper excerpts/data. Instead, I’m producing a rigorous evidence map (known vs uncertain vs tested causal links) grounded strictly in the single supplied study.

    1) Evidence map (what was measured, and what direction)

    2) Human tissue: ferroptosis signature consistency (directional, not effect sizes)

    Reported directions come from the supplied paper extraction of markers in psoriatic lesions. Direction ≠ magnitude, and this is not a meta-analytic average.

    3) Single-cell link: lipid oxidation activity ↔ Th22/Th17 pathway activity

    This is an association reported by the study’s single-cell analysis; association does not prove mechanism.

    4) “Causality steps” diagram (tested with erastin and inhibitor rescue)

    This simplified diagram reflects a tested ladder inside one paper: observation → perturbation with erastin → rescue with Fer-1 → downstream inflammation readouts; and an in vivo IMQ consistency check.

    5) What’s well-supported vs still uncertain (skeptical evidence grading)

    This bucketization is intentionally conservative: it treats “known” as “directly tested/observed in the study,” and “uncertain” as “explicitly unresolved in the paper’s limitations,” such as unclear mechanisms by which Fer-1 modulates GPX4/ACSL4.
    Limitations & blind spots (why this is not a full meta-analysis)
    • No multi-study aggregation: a quantitative meta-analysis requires multiple independent datasets/studies, but only one paper is present in the provided extraction.
    • Model dependence: IMQ is a psoriasiform proxy model; its mapping to human psoriasis mechanisms can be imperfect.
    • Small samples: human biopsies and mouse group sizes are limited.
    • Causality granularity: the study reports correlation between lipid oxidation activity and Th22/Th17 programs, but mechanistic causation for that specific coupling is not fully established.
    • Mechanistic specificity: unclear how Fer-1 modulates GPX4/ACSL4 changes mechanistically in this context.
    This will attempt an expanded evidence search and then iteratively refine the evidence map into a true multi-study synthesis.
    Note: All statements in the figures and text are grounded in the single supplied study extraction unless explicitly framed as “not possible” due to missing multi-study data.

    It will ingest the provided paper’s extracted marker directions and single-cell correlation, then render an evidence-map figure and a confidence bucket summary, and finally propose which additional papers/fields are needed for a true meta-analysis.



     Hypothesis Graveyard


    “Fer-1 acts mainly as an anti-inflammatory unrelated to ferroptosis.” Reason to deprioritize: the study’s design includes ferroptosis readouts (lipid peroxidation/oxidation markers and rescue with Fer-1) alongside inflammatory outputs, arguing for ferroptosis-linked effects rather than purely off-target anti-inflammation (within the study’s scope).


    “IMQ severity improvement proves ferroptosis is the sole driver in psoriasis.” Reason to deprioritize: the paper itself limits certainty (IMQ proxy, single inhibitor in vivo, small samples) and does not establish exclusivity.
