Abstract

We have devised a sensitive method for the isolation and structural analysis of glycosaminoglycans from two genetically tractable model organisms, the fruit fly, Drosophila melanogaster, and the nematode, Caenorhabditis elegans. We detected chondroitin/chondroitin sulfate- and heparan sulfate-derived disaccharides in both organisms. Chondroitinase digestion of glycosaminoglycans from adult Drosophila produced both nonsulfated and 4-O-sulfated unsaturated disaccharides, whereas only unsulfated forms were detected in C. elegans. Heparin lyases released disaccharides bearing N-, 2-O-, and 6-O-sulfated species, including mono-, di-, and trisulfated forms. We observed tissue- and stage-specific differences in both chondroitin sulfate and heparan sulfate composition in Drosophila. We have also applied these methods toward the analysis of tout-velu, an EXT-related gene in Drosophila that controls the tissue distribution of the growth factor Hedgehog. The proteins encoded by the vertebrate tumor suppressor genes EXT1 and 2, show heparan sulfate co-polymerase activity, and it has been proposed that tout-velu affects Hedgehog activity via its role in heparan sulfate biosynthesis. Analysis of total glycosaminoglycans from tout-velu mutant larvae show marked reductions in heparan sulfate but not chondroitin sulfate, consistent with its proposed function as a heparan sulfate co-polymerase.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
