Description Hypercholesterolemia is one of the factors contributing
to cardiovascular problems. Erythrocytes are known to
contribute its cholesterol to atherosclerotic plaque. Our
earlier study showed that erythrocytes overexpress
chondroitin sulphate/dermatan sulphate (CS/DS), a
linear co-polymer, during diabetes which resulted in
increased cytoadherence to extracellular matrix
(ECM) components. This study was carried out to determine
whether diet-induced hypercholesterolemia
had any effect on erythrocyte CS/DS and impacted
cytoadherence to ECM components. Unlike in diabetes,
diet-induced hypercholesterolemia did not show
quantitative changes in erythrocyte CS/DS but showed
difference in proportion of un-sulphated and 4-Osulphated
disaccharides. Erythrocytes from hypercholesterolemic
rats showed increased adhesion to ECM
components which was abrogated to various extents
when subjected to chondroitinase ABC digestion.
However, isolated CS/DS chains showed a different
pattern of binding to ECM components indicating
that orientation of CS/DS chains could be playing a
role in binding.
