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

It has frequently been suggested that loss of beta 2-microglobulin (beta 2m) in tumor cells may lead to malignant progression due to escape from immunological recognition. Here, we directly tested the role of beta 2m expression in tumorigenicity. A beta 2 m loss mutant (C4.4-25-), selected from the murine lymphoma EL-4, showed a marked reduction in tumorigenicity as compared with EL-4 in normal C57B1/6 (B6) mice. The reduced tumorigenicity was directly related to beta 2 m expression. Transfection of an intact murine beta 2m gene markedly increased the tumorigenic potential. The reduced tumorigenicity of C4.4-25- compared with beta 2m transfected cells was observed also in athymic B6 nu/nu mice, but was abolished in B6 mice depleted of natural killer (NK) 1.1-positive cells. These results show that restoration of beta 2m expression can promote tumorigenicity and demonstrate for the first time that induction of major histocompatibility complex class I expression by transfection can lead to escape from NK cells in vivo.
