A synthetic peptide inhibitor for alpha-chemokines inhibits the growth of melanoma cell lines.
Article in The Journal of clinical investigation, 1997. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Melanoma growth stimulatory activity (MGSA/GROalpha) is a 73 amino acid peptide sharing sequence characteristics with the alpha-chemokine superfamily. MGSA/GROalpha is produced by diverse melanoma cell lines and reported to act as an autocrine growth factor for the cells. We tested the binding of MGSA/GROalpha to melanoma cell lines, Hs 294T and RPMI7951, and found that these cells could bind to MGSA/GROalpha but not to interleukin-8. Recently, we defined a novel hexapeptide, antileukinate, which is a potent inhibitor of binding of alpha-chemokines to their receptors on neutrophils. When antileukinate was added to melanoma cells, it inhibited the binding of MGSA/ GROalpha. The growth of cells from both melanoma cell lines was suppressed completely in the presence of 100 microM peptide. The cell growth inhibition was reversed by the removal of the peptide from the culture media or by the addition of the excess amount of MGSA/GROalpha. The viability of Hs 294T cells in the presence of 100 microM peptide was > 92%. These findings suggest that MGSA/GROalpha is an essential autostimulatory growth factor for melanoma cells and antileukinate inhibits their growth by preventing MGSA/GROalpha from binding to its receptors.
