Abstract
Background Amino acids such as glutamine are important for tumor cell growth, survival and metabolism. There is renewed interest in glutamine metabolism due to the importance of reductive carboxylation in cancer. The amino acid transporter ASCT2 (SLC1A5) mediates uptake of glutamine in cancer cells. We have recently reported that ASCT2 expression is significantly upregulated in melanoma, and ASCT2 inhibition significantly decreases glutamine uptake, cell growth, cell cycle and mTORC1 pathway activation [1]. We have previously shown that ASCT2 expression is regulated by the androgen receptor in prostate cancer [2], and in this current study we further examine ASCT2 expression levels in prostate cancer. Our specific aim was to determine the impact of inhibiting ASCT2-mediated glutamine uptake and metabolism on cell growth.

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 it
