Programmed Clonal Expansion Associated with V(D)J Recombination Drives an ATM-Dependent Vulnerability Underlying Preferential Lymphocyte Depletion and Myeloid Bias Following DNA Damage.
Article in bioRxiv : the preprint server for biology, 2026. 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
Myeloid bias is a hallmark of aging and genotoxic stress, yet the mechanisms underlying the preferential suppression of lymphopoiesis and the resulting predominance of myeloid cells following DNA damage remain incompletely understood. Here, we systematically characterized the acute hematopoietic response to a clinically relevant 2 Gy dose of ionizing radiation in young adult mice. Forty-eight hours after irradiation, overall bone marrow cellularity was reduced by ~50-60%, with hematopoietic stem and progenitor cells (HSPCs) and myeloid populations declining proportionally. Strikingly, immature and naïve B cells in the bone marrow and developing T cells in the thymus exhibited profound hypersensitivity, declining by ~90%, thereby recapitulating the preferential vulnerability of lymphocytes to DNA damage. Single-cell RNA sequencing mapped this vulnerability to cells undergoing programmed clonal expansion associated with V(D)J recombination. Specifically, B and T lymphocytes immediately following productive V(D)J recombination at the immunoglobulin heavy-chain (IgH) and T-cell receptor β (TCRβ) loci were the most radiosensitive, resulting in the marked depletion of the immediately downstream small pre-B and CD4
