Circadian variation in MGMT promoter methylation and expression predicts sensitivity to Temozolomide in glioblastoma.
Article in Research square, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Recent studies show that glioblastoma (GBM) is more sensitive to Temozolomide (TMZ) in the morning. In cells, inhibiting O6-Methylguanine-DNA-Methyltransferase (MGMT) abolished time-dependent TMZ efficacy, suggesting that circadian regulation of this DNA repair enzyme underlies daily TMZ sensitivity. Here, we tested the hypotheses that MGMT-promoter methylation and protein abundance vary with time-of-day in GBM, resulting in daily rhythms in TMZ efficacy. Methods: We assessed daily rhythms in Results: We found daily rhythms in Conclusion: Our findings suggest that the likelihood of diagnosis of MGMT-promoter methylation varies with time of biopsy in GBM. Furthermore, we predict that efforts to deliver TMZ after the daily peak of MGMT activity, with exact time being dose-dependent, will significantly enhance its therapeutic efficacy.
