title: Expression of hyaluronate and hyaluronate synthase in human primary tumours and their metastases in scid mice.
abstract: Hyaluronate and hyaluronate synthase expression were examined in primary tumours and if present in metastatic deposits of human breast, colon, ovarian and small-cell lung cancer cell lines transplanted into scid mice using biotinylated hyaluronectin and immunohistochemical staining of hyaluronate synthase. Very intensive hyaluronate and hyaluronate synthase expression could be observed in peripheral areas of tumours derived from highly metastatic cell lines (HT29, MCF-7). Even smaller lung metastases of up to 15 cells showed typically a focal binding of hyaluronectin predominantly at the host-tumour interface of the metastases, indicating that increased expression is closely correlated with the degree of invasiveness and metastatic potential of malignant tumours.
