Gain of function mutations of RTK conserved residues display differential effects on NTRK1 kinase activity.
Article in Oncogene, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Activation of tyrosine kinase receptors is associated with human tumors. Tumorigenic versions of several RTKs, such as Ret, Kit and Met carry activating mutations at highly conserved residues of the tyrosine kinase domain. We have investigated the effect of some of these mutations on the NTRK1/NGF receptor, for which no naturally occurring activating point mutations have been so far detected. We introduced the following mutations in NTRK1 tyrosine kinase domain: (i) D668N equivalent to Met D1246N associated to HPRC; (ii) D668V modelled on Kit D816V found in mastocytosis; (iii) M688T corresponding to Ret M918T associated to the cancer syndrome MEN2B. The Met-like mutation rendered the NTRK1 receptor more responsive to ligand, as observed for the corresponding mutation in Met. On the contrary the Kit-like D668V resulted as neutral mutation. Surprisingly, the MEN2B-like M688T completely abrogated NTRK1 receptor activity, resulting as a loss of function mutation. Our results show that the mutations tested, although involving conserved amino acids in highly homologous regions, exert distinct effects in different receptors, and suggest a very peculiar auto-inhibitory mechanism for NTRK1.
