Immunohistochemistry analysis reveals lysyl oxidase-like 3 as a novel prognostic marker for primary melanoma
Bibliographic record
Abstract
Lysyl oxidase-like 3 (LOXL3) is an extracellular enzyme involved in the synthesis of collagen and elastin, and it has been reported to promote melanoma cell proliferation and invasion in vitro. However, the expression level of LOXL3 at different stages of melanocytic lesions and the role of LOXL3 in melanoma pathogenesis remain unknown. Immunohistochemical staining of LOXL3 in a tissue microarray of 373 biopsies at different melanocytic stages was conducted. The correlation between LOXL3 expression and patient survival was examined using Kaplan-Meier survival analysis. Univariate and multivariate Cox regression analyses were conducted to study the hazard ratios. The tissue microarray study revealed that stronger expression of LOXL3 protein was found at more advanced melanocytic stages (P < 0.0001; χ2 test). Increased LOXL3 expression was associated with enhanced tumor thickness and mitosis. Survival analysis showed significantly worsened prognosis in primary melanoma patients when the LOXL3 expression level was higher (P = 0.043; log-rank test). Multivariate Cox regression analysis further showed that LOXL3 expression is a prognostic factor for primary melanoma patient survival (P = 0.04). LOXL3 expression is positively correlated with tumor progression and invasion, and its overexpression is associated with worse prognosis of primary melanoma patients. LOXL3 can serve as a prognostic marker to help identify primary melanoma patients at higher risks of death.

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.
