Developmental genetic analysis of troponin T mutations in striated and nonstriated muscle cells of Caenorhabditis elegans.
Article in The Journal of cell biology, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 50 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
We have been investigating a set of genes, collectively called mups, that are essential to striated body wall muscle cell positioning in Caenorhabditis elegans. Here we report our detailed characterization of the mup-2 locus, which encodes troponin T (TnT). Mutants for a heat-sensitive allele, called mup-2(e2346ts), and for a putative null, called mup-2(up1), are defective for embryonic body wall muscle cell contraction, sarcomere organization, and cell positioning. Characterizations of the heat-sensitive allele demonstrate that mutants are also defective for regulated muscle contraction in larval and adult body wall muscle, defective for function of the nonstriated oviduct myoepithelial sheath, and defective for epidermal morphogenesis. We cloned the mup-2 locus and its corresponding cDNA. The cDNA encodes a predicted 405-amino acid protein homologous to vertebrate and invertebrate TnT and includes an invertebrate-specific COOH-terminal tail. The mup-2 mutations lie within these cDNA sequences: mup-2(up1) is a termination codon near NH2 terminus (Glu94) and mup-2(e2346ts) is a termination codon in the COOH-terminal invertebrate-specific tail (Trp342). TnT is a muscle contractile protein that, in association with the thin filament proteins tropomyosin, troponin I and troponin C, regulates myosin-actin interaction in response to a rise in intracellular Ca2+. Our findings demonstrate multiple essential functions for TnT and provide a basis to investigate the in vivo functions and protein interactions of TnT in striated and nonstriated muscles.
