Název v původním jazyce

Loss of the p53 tumor suppressor activity is associated with negative prognosis of mantle cell lymphoma

Popis výsledku v původním jazyce

Mantle cell lymphoma (MCL) is typified by translocation t(11;14)(q13;q32) causing upregulation of cyclin D1 and deregulation of cell cycle. The cyclin D1 activation plays a critical role in MCL pathogenesis but additional oncogenic events, such as abberations of the ARF/MDM2/p53 pathway are also necessary for progression of the disease. We analyzed the p53 tumor suppressor in tumor tissue of 33 patients with MCL. The p53 status was determined by functional analyses in yeast (FASAY) and by cDNA sequencing. The level of the p53 protein was assessed by immunoblotting. Loss of the p53-specific locus 17p13.3 was detected by FISH. Mutations in the p53 gene were detected in nine samples and they included eight missense mutations and one short deletion causingframe shift and premature stop codon formation in position 169.
