1 · What the graph read from it

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.

2 · The registry

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 location of MLL translocation breakpoints within therapy-related acute myeloid leukemia linked to drugs targeting Topoisomerase II and infant acute leukemia (IAL) are biased toward the intron 11-exon 12 region of MLL, although lacking a comprehensive explanation. To address this, blood samples were taken from breast cancer and lymphoma patients receiving Topoisomerase II inhibitor therapy. Inverse PCR analysis was used to interrogate the exon 12 region of MLL for rearrangements. Eleven of 19 observed translocations showed breakpoint junctions restricted to a single 5 bp location within exon 12. A similarly restricted distribution (11/20 breakpoint junctions) was observed in TK6 cells exposed to either estrogen (linked to IAL) or anti-CD95 antibody. The translocation hotspot was at the 5' edge of a 10-bp tract matched with a perfect palindrome, 101 bp distant. A high stringency Topoisomerase II consensus sequence binding site was noted at the geometric midpoint of the palindromes. Ligation-mediated PCR to screen TK6 cells exposed to anti-CD95 antibody showed 14/37 (38%) of DNA breaks adjacent to the 5' palindrome and 10/37 (27%) at the 3' partner. We propose a model whereby Topoisomerase II facilitates the organization of nuclease-sensitive secondary structures, stabilized by palindrome association, which are prone to rearrangement.
