Abstract
During the process of tumor growth, cancer cells will be subjected to intermittent hypoxia. This results from the delay in the development of the vascular network in relation to the proliferation of cancer cells. The hypoxic nature of a tumor has been demonstrated as a negative factor for patient survival. To evaluate the impact of hypoxia on the survival and migration properties of low and high‑grade bladder cancer cell lines, two low‑grade (MGHU‑3 and SW‑780) and two high‑grade (SW‑1710 and T24) bladder cancer cell lines were cultured in normoxic (20% O<sub>2</sub>) or hypoxic atmospheric conditions (2% O<sub>2</sub>). The response of bladder cancer cell lines to hypoxic atmospheric cell culture conditions was examined under several parameters, including epithelial‑mesenchymal transition, doubling time and metabolic activities, thrombospondin‑1 expression, whole Matrix Metallo‑Proteinase activity, migration and resistance to oxidative stress. The low‑grade cell line response to hypoxia was heterogeneous even if it tended to adopt a more aggressive profile. Hypoxia enhanced migration and pro‑survival properties of MGHU‑3 cells, whereas these features were reduced for the SW‑780 cell line cultured under low oxygen tension. The responses of tested high‑grade cell lines were more homogeneous and tended to adopt a less aggressive profile. Hypoxia drastically changed some of the bladder cancer cell line properties, for example matrix metalloproteinases expression for all cancer cells but also switch in glycolytic metabolism of low grade cancer cells. Overall, studying bladder cancer cells in hypoxic environments are relevant for the translation from <em>in vitro</em> findings to <em>in vivo</em> context.

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
