RECK and astrocytoma (excluding glioblastoma): In the present study, two novel alternative transcripts of the RECK tumor suppressor gene, namely: RECK-B (1,548bp) and RECK-I (1,101bp), were identified and isolated by RT-PCR and their expression profiles were investigated using quantitative real time PCR (qRT-PCR) assays in both human astrocytomas of different malignant grades and in a normal tissue RNA panel.
