Abstract
Abstract Glioblastoma (GBM) is the most common and deadliest form of brain tumor and remains amongst the most difficult cancers to treat. Brevican (Bcan), a central nervous system (CNS)‐specific extracellular matrix protein, is upregulated in high‐grade glioma cells, including GBM. A Bcan isoform lacking most glycosylation, dg‐Bcan, is found only in GBM tissues. Here, dg‐Bcan is explored as a molecular target for GBM. In this study, a d ‐peptide library is screened to identify a small 8‐amino acid dg‐ B can‐ T argeting P eptide (BTP) candidate, called BTP‐7 that binds dg‐Bcan with high affinity and specificity. BTP‐7 is preferentially internalized by dg‐Bcan‐expressing patient‐derived GBM cells. To demonstrate GBM targeting, BTP‐7 is radiolabeled with 18 F, a radioisotope of fluorine, and increased radiotracer accumulation is found in intracranial GBM established in mice using positron emission tomography (PET) imaging. dg‐Bcan is an attractive molecular target for GBM, and BTP‐7 represents a promising lead candidate for further development into novel imaging agents and targeted therapeutics.

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
