Abstract 1873: Water-pipe smoking induces epithelial-mesenchymal transition and enhances cell invasion of human breast cancer cells
Bibliographic record
Abstract
Water-pipe smoking (WPS) has been recently recognized as an emerging risk factor for human health. The exact role of WPS in human breast cancer development and progression has not been investigated yet. We herein explored for the first time the impact of WPS on epithelial-mesenchymal transition (EMT) and cell invasion, which are considered crucial for cancer progression and metastasis in human carcinomas including breast. Our data revealed that WPS can initiate EMT in two human breast cancer cell lines, MCF-7 and BT20. WPS enhanced the cell invasion ability of both cell lines compared with their matched controls. We also found that WPS provoke a down- and up-regulation of two important regulator genes of cancer progression: E-cadherin and focal adhesion kinase (FAK). In addition, our data pointed out that WPS induces the activation of Erk1/Erk2 signaling pathways, which could be behind the stimulation of EMT and deregulation of E-cadherin and FAKgenes. Taken together, our results imply the significant effects of WPS on several cellular processes and genes involved in breast cancer progression and metastasis. Further studies are necessary to identify the clinical relevance and exact role of WPS in human carcinogenesis and metastasis.

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.
