Abstract:
To investigate the expression level of cyclic nucleotide phosphodiesterase (PDE) 7B mRNA and its prognostic value in mantle cell lymphoma (MCL), the real-time quantitative RT-PCR (QPCR) was used to detect pde7b expression levels of bone marrow mononuclear cells from 20 newly diagnosed MCL patients with bone marrow involvement and peripheral blood mononuclear cells from 20 normal persons, the association of pde7b expression levels with prognostic indexes was analyzed by statistical software. The results showed that the median values of pde7b mRNA expression level in 20 MCL patients and normal controls were 8.7 × 10(-4) (4 × 10(-5) - 6.9 × 10(-3)) and 0.5 × 10(-4)(0.18 × 10(-4) - 1.7 × 10(-4)) respectively (p = 0.001). No association was found between pde7b expression and patients' clinical baseline information (gender and age), as well as certain prognostic factors, leukocyte count, lactate dehydrogenase level, CD38 expression and immunoglobulin heavy-chain variable region mutation status, but pde7b mRNA expression was significantly associated with cytogenetic abnormality, β(2)-microglobulin level and ZAP-70 expression. It is concluded that the pde7b mRNA expression is obviously higher in MCL patients compared with normal controls and significantly correlates with unfavorable cytogenetic characteristics in MCL. The pde7b may be used as a novel prognostic indicator in MCL, and has important clinical significance.
