Abstract
The PI3K/AKT pathway plays an important role in the development of osteosarcoma. RNF38 interferes with activation of the AKT pathway. Cryptochrome1 (CRY1) inhibits osteosarcoma proliferation through the AKT pathway. We aimed to clarify whether RNF38 affects the proliferation of osteosarcoma cells by regulating the PI3K/AKT pathway through its interaction with CRY1. The mRNA levels of RNF38 were determined using qRT-PCR. Protein levels of RNF38, p-p70S6, p70S6, +p-AKT, AKT, p-mTOR, mTOR, and CRY1 were detected by western blotting. The proliferation of osteosarcoma cells was detected using CCK-8 and colony formation assays. The interaction between CRY1 and RNF38 was detected by co-immunoprecipitation and GST pull-down assays. RNF38 expression was higher in Saos-2 and U20S cells than in hFOB cells. Overexpression of RNF38 promoted the proliferation of osteosarcoma cells, the number of colonies, and p-AKT and p-mTOR levels, suggesting that overexpression of RNF38 activated the PI3K/AKT pathway. In addition, RNF38 directly binds to the N-terminal of CRY1. The simultaneous knockdown of RNF38 and CRY1 restored the level of p-AKT, which was reduced by RNF38 knockdown alone. RNF38 affects the proliferation of osteosarcoma cells by regulating the PI3K/AKT pathway through its interaction with CRY1.

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
