This study investigated expression profiles of tumor necrosis factor (TNF)-related apoptosis inducing ligand (TRAIL) pathway components and mechanisms underlying TRAIL-induced apoptosis in mucosa associated lymphoid tissue (MALT) lymphoma. Genetic aberrations including translocations and trisomies were assessed by reverse transcription polymerase chain reaction and fluorescence in situ hybridization. Expression of TRAIL, death receptors 4 and 5, decoy receptors 1 and 2, and FADD-like interleukin-1 b -converting enzyme (FLICE) inhibitory protein was analyzed by immunohistochemistry. All 32 patients under study showed some alterations in TRAIL pathway mainly involving loss of death receptors (37.5%), gain of decoy receptors (3.1%) or both (59.4%). Decoy receptor 2 (DcR2) was highly expressed in patients with normal cytogenetic status as compared to those with cytogenetic aberrations ( p=0.005). Moreover, DcR2 expression correlated signifi cantly with nuclear factor-kappa B (NF- kappa B) expression ( R=0.372, p= 0.047). High expression of DcR2 in patients with normal cytogenetic status and its significant correlation with NF- kappa B expression provides a potential clue to evasion of immune surveillance in cytogenetically normal MALT lymphomas.
