Clonal pattern in warthin's tumor. viagra pills from canada Other data demonstrated that warthin's tumor do not have evidence of dna mismatch repair defects at the genomic or protein expression level. These results argue against a general neoplastic origin. The cytogenetic data available on this tumor are rather scare. However, analysis of cytogenetic findings revealed, beside normal karyotypes, also structural alterations and numerical deviations in some cases. T(11;19)(q21;p13) translocation with expression of chimeric genes crtc1 - maml2 is a very rare event in warthin's tumor. order viagra Identification of cytogenetic subgroups in warthin's tumor may suggest that it might be a pathogenetically heterogeneous group of lesions. When the fusion gene is present in this tumor type, it seems to be restricted in special cases with indeterminate morphology, especially involving necrosis and subsequent metaplasia. Deletions of mitochondrial dna is significantly higher in oncocytic tumor cells than parotid epithelia cells. viagra generic In this context damage of mitochondrial dna as a result of an increase in oxidative damage of cigarette smoke could be discussed.
