| pubmed-article:6863247 | pubmed:abstractText | Proteoglycans deposited in the basal lamina of [14C] glucosamine-labeled normal and [3H]glucosamine-labeled transformed mouse mammary epithelial cells grown on type I-collagen gels, were extracted in 4 M guanidinium chloride and cofractionated over Sepharose CL 4B. The heparan sulfate chains carried by these proteoglycans were isolated by treatment with alkaline borohydride, protease K, chondroitinase ABC, and cetylpyridinium chloride precipitation. Heparan sulfate isolated from transformed cell cultures consistently eluted from DEAE-cellulose at lower salt concentrations and was of smaller apparent Mr when chromatographed over Sepharose CL 6B, than heparan sulfate of normal cell cultures. Experiments using doubly labeled cultures ([3H]glucosamine and [35S]sulfate) demonstrated an approximately 30% reduction in the sulfate/hexosamine ratio in heparan sulfate derived from transformed cultures. Both N- and O-sulfate were decreased. The decreased Mr and decreased sulfation of heparan sulfate upon transformation appear sufficient to explain the altered heparan sulfate/chondroitin sulfate ratios previously observed in these cells. These changes may have implications for the molecular interactions in which these proteoglycans are normally engaged during basal lamina assembly, and cause the poor basal lamina formation displayed by these transformed cells. | lld:pubmed |
