CXCL6 promotes human hepatocyte proliferation through the CXCR1–NFκB pathway and inhibits collagen I secretion by hepatic stellate cells
Bibliographic record
Abstract
Hepatocyte proliferation and collagen I (COLI) secretion are important processes during liver regeneration. This study aimed to investigate the role of CXCL6 in hepatocyte proliferation and COLI secretion. Serum CXCL6 levels in patients with chronic hepatitis B (CHB) were examined and the effects of CXCL6 on the proliferation of L02 hepatocytes and the secretion of COLI from LX2 human hepatic stellate cells were evaluated. We found that serum CXCL6 levels increased gradually with disease progression of CHB, and there was positive correlation between serum CXCL6 level and alanine transaminase (ALT) and aspartate transaminase (AST). In vitro, CXCL6 promoted L02 proliferation but this was blocked upon CXCR1 knockdown. The level of phospho-IκBα was upregulated by CXCL6 but downregulated by CXCR1 siRNA in L02 cells. CXCL6 inhibited the secretion of COLI by LX2 cells, dependent on CXCR1 and CXCR2. Taken together, these data suggest that increased expression of CXCL6 during CHB could promote hepatocyte proliferation through the CXCR1-NFκB pathway and inhibit the secretion of COLI by hepatic stellate cells.

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.
