Expression and tumor-promoting effects of caprin-1 in human glioma
Bibliographic record
Abstract
Background: Cytoplasmic activation/proliferation-associated protein-1 (caprin-1) is a newly discovered RNA-binding protein and is now recognized as one of the putative oncogenes. This study was performed to reveal its presence in human gliomas and its oncogenic functions in human glioblastoma-derived Denver brain tumor research group 05 (DBTRG-05MG) cells. Materials and Methods: Clinical glioma samples were cumulatively collected for the identification of caprin-1 using immunoblot analysis and immunofluorescence detection. DBTRG cells transfected with caprin-1-specific small interfering RNA (siRNA) were used to verify caprin-1's oncogenic function using a real-time cell analyzer (RTCA) and scratch assay. Results: Seven of eight collected glioma samples were identified as positive for caprin-1 expression. siRNA dose-responsive inhibition of cell proliferation was observed in DBTRG cells with RTCA, and cell migration rate was significantly reduced by siRNA transfection (P < 0.05). Conclusion: The present study identified the higher expression of caprin-1 in human glioblastoma-derived DBTRG cells. Its oncogenic functions, mainly enhanced cell proliferation and promoted cell migration capacity, were also verified in these cells. This study provided fundamentals for developing caprin-1 as a therapeutic target for the treatment of gliomas.

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.
