Sequencing and characterization of the porcine α-galactosidase A gene: towards the generation of a porcine model for Fabry disease.

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
Fabry disease is an inherited lysosomal disorder caused by a deficiency of alpha-galactosidase A (α-gal A). The systemic accumulation of substrate, mainly globotriaosylceramide (Gb3), results in organ failure. Although Gb3 accumulation has been observed in an α-gal A-deficient mouse model, important clinical manifestations were not seen. The pursuit of effective treatment for Fabry disease through gene therapy, for example, has been hampered by the lack of a relevant large animal model to assess the efficacy and safety of novel therapies. Towards assembling the tools to generate an alternative animal model, we have sequenced and characterized the porcine ortholog of the α-gal A gene. When compared to the human α-gal A, the porcine α-gal A showed a high level of homology in the coding regions and located at chromosome Xq22. Cell lysate and supernatants from Fabry patient-derived fibroblasts transduced with a lentiviral vector (LV) carrying the porcine α-gal A cDNA (LV/porcine α-gal A), showed high levels of α-gal A activity and its enzymological stability was similar to that of human α-gal A. Uptake of secreted porcine α-gal A was observed into non-transduced cells and was partially inhibited by soluble mannose-6-phosphate. Furthermore, Gb3 accumulation was reduced in Fabry patient-derived fibroblasts transduced with the LV/porcine α-gal A. In conclusion, we elucidated and characterized the porcine α-gal A gene and enzyme. Similarity in enzymatic profile and chromosomal location between α-gal A of porcine and human origins may be of great advantage for the development of a large animal model for Fabry disease.
