To assess the clinical significance of AML1/ETO gene detected by nested reverse transcriptase polymerase chain reaction, the outcome of 7 patients with acute myeloblastic leukemia between 3 and 14 years of age were presented. All patients had complete remission (CR) at the end of induction (AMLMRC 10 protocol) and 4 underwent unpurged autologous, 2 allogeneic (from matced siblings) non-T-cell-depleted bone marrow transplantations (BMT) in first CR. One patient died due to allogeneic BMT-related complications, and 4 patients relapsed at 13, 17, 18, and 26 months. Only one patient achieved second CR. All relapsed patients died between 18 and 36 months with resistant disease (n = 3) or infection during salvage chemotherapy (n = 1). Two patients who had autologous BMT are alive and disease free at 44 and 50 months. Although statistical significance could not be shown, event-free survival and overall survival rates of AML1/ETO-positive patients (28.57 and 28.57% , respectively) at 3.5 years were even lower than those of AML1/ETO-negative patients. The results confirm some previous reports that AML1/ETO gene in children and adolescents is not a favorable prognostic factor. [ABSTRACT FROM AUTHOR]

Objective: 30-40% of patients with epilepsy have resistance to medical treatment. The major genetic mechanism postulated to underlie this resistance known as Multidrug resistance gene 1 (MDR1), transports the drugs from intracellular to extracellular area. Methods: 103 temporal lobe epilepsy patients' (59 of the patients had mesial temporal sclerosis and 44 patients had cryptogenic etiology) and 174 healthy controls' samples were evaluated for MDR1 gene (C3435T) polymorphism by polimerase chain reaction and restriction fragment length polymorphisms. Results: In all patients and TLE patients without MTS, CT genotype was found to be lower than that of the control group (p=0,004 ve p=0,008). CT genotype was statistically lower in the group without MTS than the group with MTS (p=0,0008). It is noted that the patients with a history of status epilepticus had significantly higher MDR1 gene TT genotype (p=0,027). There was no correlation between other clinical features and MDR1 genotype. Conclusions: Despite the difference of heterozygote CT genotype frequency in patient and control populations, no correlation between clinical features and MDR1 genotype was found. This data may show diverse genetic background of different populations. Studies of mutation analysis will play an important role to understand the pathophysiology of this disease.

Abstract: We investigated the peripheral blood gene expression profile of interferon induced transmembrane protein 1 (IFITM1) in sixty chronic myeloid leukemia (CML) patients classified according to new prognostic score (NPS). IFITM1 is a component of a multimeric complex involved in the trunsduction of antiproliferative and cell adhesion signals. Expression level of IFITM1 was found significantly different between the high- and low-risk groups (P = 9.7976 × 10-11) by real-time reverse transcription polymerase chain reaction (RT-PCR). Higher IFITM1 expression correlated with improved survival (P = 0.01). These results indicate that IFITM1 expression profiling could be used for molecular classification of CML, which may also predict survival. [Copyright &y& Elsevier]
