PTIP epigenetically regulates DNA damage-induced cell cycle arrest by upregulating PRDM1.
Article in Scientific reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
The genome is constantly exposed to DNA damage from endogenous and exogenous sources. Fine modulation of DNA repair, chromatin remodeling, and transcription factors is necessary for protecting genome integrity, but the precise mechanisms are still largely unclear. We found that after ionizing radiation (IR), global trimethylation of histone H3 at lysine 4 (H3K4me3) was decreased at an early (5 min) post-IR phase but increased at an intermediate (180 min) post-IR phase in both human and mouse hematopoietic cells. We demonstrated that PTIP, a component of the MLL histone methyltransferase complex, is required for H3K4me3 upregulation in the intermediate post-IR phase and promotes cell cycle arrest by epigenetically inducing a cell cycle inhibitor, PRDM1. In addition, we found that PTIP expression is specifically downregulated in acute myeloid leukemia patients. These findings collectively suggest that the PTIP-PRDM1 axis plays an essential role in proper DNA damage response and its deregulation contributes to leukemogenesis.
