A der(8)t(8;11) chromosome in the Karpas-620 myeloma cell line expresses only cyclin D1: yet both cyclin D1 and MYC are repositioned in close proximity to the 3'IGH enhancer.

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 Karpas-620 human myeloma cell line (HMCL) expresses high levels of Cyclin D1 (CCND1), but has a der(8)t(8;11) and a der(14)t(8;14), and not a conventional t(11;14). Fluorescent in situ hybridization (FISH) and array comparative genomic hybridization (aCGH) studies suggest that der(14)t(11;14) from a primary translocation underwent a secondary translocation with chromosome 8 to generate der(8)t(8;[14];11) and der(14)t(8;[11];14). Both secondary derivatives share extensive identical sequences from chromosomes 8, 11, and 14, including MYC and the 3' IgH enhancers. Der(14), with MYC located approximately 700 kb telomeric to the 3'IGH enhancer, expresses MYC. By contrast, der(8), with both CCND1 and MYC repositioned near a 3'IGH enhancer, expresses CCND1, which is telomeric of the enhancer, but not MYC, which is centromeric to the enhancer. The secondary translocation that dysregulated MYC resulted in extensive regions from both donor chromosomes being transmitted to both derivative chromosomes, suggesting a defect in DNA recombination or repair in the myeloma tumor cell.
