Abstract

Hyaluronan (HA), a large negatively-charged polysaccharide, is a major component of vessel basal membrane. HA is expressed by a variety of cells, including tumor and endothelial cells. We hypothesized that HA could be up-regulated by hypoxia to enhance vessel formation. To determine the effect of hypoxia on the production of HA, tumor cells were treated with either media alone (control) or a hypoxia inducer (CoCl or NaN3) for 24 h. The level of HA in the media was then measured by ELISA. The results showed that both CoCl and NaN3 induced the production of HA. Since the low molecular weight form of HA (SMW) possesses pro-angiogenic properties, we investigated whether hypoxia-induced HA can be processed into SMW. Under hypoxic conditions, the activity of hyaluronidase, the enzyme responsible for degrading HA, was measured by an ELISA-like assay. The activity of hyaluronidase was shown to be up-regulated by hypoxia and, further, could carry out the function of processing HA into SMW. In addition, the hypoxic areas of tumor tissues were stained strongly with biotinylated HA-binding proteins, indicating that the level of HA was high compared to the oxic areas. This study demonstrates that hypoxia can stimulate the production of HA and the activity of hyaluronidase, which may promote angiogenesis as a compensation mechanism for hypoxia.

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.
