Up‐regulation of <scp><i>Anxa2</i></scp> gene promotes proliferation and invasion of breast cancer <scp>MCF</scp>‐7 cells
Bibliographic record
Abstract
OBJECTIVE: The metastatic ability of breast cancer cells with chemoresistant properties is higher when compared to that of their parental wild-type cells. Expression of AnnexinA2 (Anxa2), a 36-kDa calcium-dependent phospholipid binding protein, is increased in metastatic tumours and has been found to be associated with the phenotype of drug resistance and metastasis. MATERIALS AND METHODS AND RESULTS: In the present study, we found that up-regulation of Anxa2 correlates with enhanced migration and invasion ability of MCF-7 breast cancer cells both in vitro and in vivo. Western blot analysis revealed that exposure to chemotherapeutic drugs may induce elevated expression of Anxa2. In addition, our data have shown that Anxa2 might influence proliferation, migration and invasion of MCF-7 cells by increasing expression of c-myc and cyclin D1 via activation of Erk1/2 signalling pathways. CONCLUSION: Our findings suggest that up-regulation of Anxa2 may play an important role in modulating proliferation and invasion of breast cancer MCF-7 cells through regulation of many relevant downstream target genes.

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.
