TRAF7 inhibits proliferation and migration of esophageal squamous cell carcinoma by ubiquitination-mediated degradation of SOX12
Bibliographic record
Abstract
Tumor necrosis factor receptor-associated factor 7 (TRAF7), a member of the tumor necrosis factor receptor superfamily, is known as an E3 ubiquitin ligase and has been shown to contribute to the progression of various cancers. However, the function of TRAF7 in esophageal squamous cell carcinoma (ESCC) remains unclear. Here, our findings demonstrate a marked downregulation of TRAF7 protein expression in ESCC cell lines compared to non-neoplastic esophageal epithelial cells. Overexpression of TRAF7 inhibited cell proliferation and migration of ESCC cells, as well as promoted cell apoptosis and blocked cell cycle at the G2/M phase. In this study, we observed that TRAF7 interacted with the SOX12 protein and promoted ubiquitin-proteasome-mediated degradation of SOX12 via K48-linked ubiquitination in ESCC cells. Rescue experiments further confirmed that TRAF7's inhibitory effects on tumor cell proliferation and migration in ESCC cells partly depended on SOX12. In summary, our research reveals that TRAF7 functions as a tumor suppressor partially by promoting K48-linked ubiquitination-mediated degradation of the SOX12 protein.

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.
