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

We describe here the isolation and sequencing of a previously uncharacterized HLA class I gene. This gene, HLA-5.4, is the third non-HLA-A,B,C gene characterized whose sequence shows it encodes an intact class I protein. RNase protection assays with a probe specific for this gene demonstrated its expression in B lymphoblastoid cell lines, in resting T cells, and skin cells, while no mRNA could be detected in the T cell line Molt 4. Consistent with a pattern of expression different from that of other class I genes, DNA sequence comparisons identified potential regulator motifs unique to HLA-5.4 and possibly essential for tissue-specific expression. Protein sequence analysis of human and murine class I antigens has identified 10 highly conserved residues believed to be involved in antigen binding. Five of these are altered in HLA-5.4, and of these, three are nonconservative. In addition, examination of the HLA-5.4 DNA sequence predicts that the cytoplasmic segment of this protein is shorter than that of the classical transplantation antigens. The 3' untranslated region of the HLA-5.4 gene contains one member of a previously undescribed multigene family consisting of at least 30 members. Northern analysis showed that several of these sequences were transcribed, and the most ubiquitous transcript, a 600-nucleotide polyadenylated mRNA, was found in all tissues and cells examined. This sequence is conserved in the mouse genome, where a similar number of copies were found, and one of these sequences was also transcribed, yielding a 600-nucleotide mRNA. The characterization of this unique HLA class I gene and the demonstration of its tissue-specific expression have prompted us to propose that HLA-5.4 be designated HLA-F.
