Transcription profiling of human ermal lymphatic endothelial cells (LEC) with those isolated from tumours of murine T241/VEGF-C/GFP metastatic fibrosarcoma reveals lymphatic endothelium of metastatic tumours has a distinct transcription profile.

ABSTRACT: Invasion of lymphatic vessels is a key step in the metastasis of primary tumour cells to draining lymph nodes. Recent evidence indicates that such metastasis can be facilitated by tumour lymphangiogenesis, although it remains unclear whether this is a consequence of increased lymphatic vessel numbers or alteration in the properties of the vessels themselves. Here we have addressed this important question by comparing the RNA profile of normal dermal lymphatic endothelial cells (LEC) with those isolated from tumours of murine T-241/VEGF-C metastatic fibrosarcoma. Our findings reveal significant changes in the expression of some 792 genes in tumour lymphatics (â?¥ 2 fold up/downregulation, p â?¤ 0.05), involving particularly transcripts associated with junctional adhesion, immunomodulation,
