Creatine kinase B promotes non–small cell lung cancer survival and metastasis
Bibliographic record
Abstract
Creatine kinase (CK) catalyzes the reversible transfer of a phosphoryl group from ATP to creatine. There are four distinct CK genes (CKM [muscle-type CK], CKB [brain-type CK], CKMT1 [ubiquitous-type CK], and CKMT2 [sarcomeric-type CK]) with cell-type selective expression and subcellular localization. In cancer, uncontrolled cell proliferation drives aggressive migration and invasion into nearby tissues and distant organs. While creatine metabolism is known to support cancer cell survival, the specific roles of individual CK isoenzymes remain unclear. Here, we demonstrate that CKB is essential for CK enzymatic activity in several cancer cell lines, including non-small cell lung cancer (H1299), osteosarcoma (143B), and ovarian adenocarcinoma (OVCAR8). Moreover, we demonstrate that CKB promotes metastasis of H1299 cells to the lung and liver in vivo, a process associated with enhanced anoikis resistance.

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.
