Enhancing chemotherapeutic responses in CNS malignancy through suppression of hyperactive DNA damage repair pathways
Bibliographic record
Abstract
Current methods to treat medulloblastoma (MB) and malignant glioma (MG) are highly intrusive with three-year survival. Recurrence is high due to chemoradio-resistance. We are targeting DNA repair pathways through inhibitors of DNA repair proteins; Poly (ADP-Ribose) Polymerase (PARP1i), DNA-dependent protein kinase (DNA-PKi) and Ataxia-Telangiectasia Mutated (ATMi) to sensitize tumours to DNA damaging agents. However, differing tumours have variable expression of these enzymes/repair pathway(s) activity, therefore; their identification and inhibition may enhance current treatment efficacy. High-throughput comet assay revealed enhanced drug-mediated tumour cell death in MB cell lines with TOPI+PARP1i with activation of specific repair pathways. Further, RNA-Seq analysis revealed PARP1 upregulated in DAOYMB and downregulated in D283; while BRCA1 downregulated in DAOYMB and upregulated in D283MB, suggesting defective Homologous recombination (HRR) pathway, hence synthetic lethality in MB cell line (DAOYMB). Therefore, I have identified unique DNA repair enzymes, which may mediate specific differential chemo-radioresistant phenotypes in MB.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
