Chlorate treatment was also found to inhibit the deposition and assembly of ECM components such fibronectin and laminin.

Fibronectin immunostaining was altered in beta-xyloside-treated eyes, whereas in cell culture, chlorate induced formation of thick fibronectin fibrils, to which tenascin C colocalized.
METHODS: Outflow facility was measured in perfused porcine and human anterior organ cultures treated with 20 or 50 mM sodium chlorate, or 1 mM beta-xyloside.

Gynecol Oncol. 2003 Apr;89(1):60-72.

RESULTS: PC880 cells adhered well to fibronectin, laminin, and vitronectin in an integrin-dependent manner.
Treatment of PC880 cells with sodium chlorate also decreased invasiveness (80% of control), further confirming the role of cell surface proteoglycans.

Co-incubation of CTGF with heparin or perturbation of cell surface HSPGs with heparinase or sodium chlorate completely blocked adhesion of activated HSCs to all CTGF isoforms.
Freshly isolated HSCs demonstrated only weak binding to CTGF but strong binding to fibronectin.

When the cell lysate used was prepared from MDCK cells pretreated with 20 mM sodium chlorate, a metabolic sulphation inhibitor, the complex formed between the two proteins could no longer be detected, indicating that the binding of the TyrS-binding protein is through the TyrS residue (s) of gp 80.
Furthermore, radioactive pulse-chase experiments revealed that the newly synthesized radiolabelled fibronectin and gp 80 were present in complexes with the TyrS-binding protein in MDCK cells pulse-labelled with [35S] methionine or [35S] sulphate.

Inhibition of sulfation of cell surface glycosaminoglycans by treatment with sodium chlorate significantly reduced both the formation of the fibronectin matrix and cell proliferation in response to FGF-2, suggesting an involvement of the low-affinity sulfated glycosaminoglycan FGF receptor system.

The EC carrying beads were spread over a confluent human aortic SMC monolayer and cocultured for 48 hr, allowing the EC to migrate from beads onto the underlying SMC monolayer in the presence of sodium chlorate, cycloheximide (CHM), or anti-fibronectin monoclonal antibody (anti-FN mAb).

In this work we verified that undersulfation of proteoglycans and other sulfated molecules, induced by sodium chlorate treatment, inhibited C6 glioma cells proliferation in a dose-dependent way.
The treatment also impaired in a dose-dependent manner, C6 cell adhesion to extracellular matrix (ECM) proteins (collagen IV, laminin and fibronectin).

To assess the role of the extracellular matrix (ECM) in skeletal muscle differentiation, the specific inhibitors of proteoglycan synthesis, sodium chlorate and beta-D-xyloside, were used.
Myoblast treatment with each inhibitor affected the deposition and assembly of the ECM constituents glypican, fibronectin, and laminin.

We found that sodium chlorate, a specific inhibitor of PAPS synthetase, inhibited proteoglycan sulfation during chondrogenesis.
Inhibition of sulfation also accelerated the down-regulation of N-cadherin and fibronectin during chondrogenesis.
