CEACAM1 is a direct SOX10 target and inhibits melanoma immune infiltration and stemness
Bibliographic record
Abstract
SOX10 is a key regulator of melanoma progression and promotes a melanocytic/differentiated state. Here we identified melanoma cell lines lacking SOX10 expression which retain their in vivo growth capabilities. More importantly, we find that SOX10 can regulate T-cell infiltration in melanoma while also decreasing common cancer stem cell (CSC) properties. We show that SOX10 regulates CEACAM1, a surface protein with immunomodulatory properties. SOX10 directly binds to a distal CEACAM1 promoter region approximately 3-4kbps from the CEACAM1 transcriptional start site. Furthermore, we show that a SOX10-CEACAM1 axis can suppress CD8 + T-cell infiltration as well as reduce CSC pool within tumors, leading to reduced tumor growth. Overall, these results identify SOX10 as a direct regulator of CEACAM1, and uncover both a pro- and anti-tumorigenic roles for SOX10 in melanoma.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
