ABSTRACT

OBJECTIVE: Nuclear factor kappa B (NF-κB) is an important transcription factor in cancer and NF-κB activation has been seen in angiogenesis, tumor progression, and metastasis. Relationships between specific NF-κB gene networks, leukemogenesis, and radiation exposure are still unknown. Our aim was to study the expression levels of the NF-κB1, NF-κB2, and Rel genes in hematological malignancies in the post-Chernobyl period. MATERIALS AND METHODS: We analyzed gene expression levels of NF-κB1, NF-κB2, and Rel in 49 B-cell chronic lymphocytic leukemia, 8 B-cell non-Hodgkin's lymphoma, 3 acute myeloid leukemia, 3 chronic myeloid leukemia, 2 hairy cell leukemia, 2 myelodysplastic syndrome, and 2 T-cell large granular lymphocytic leukemia patients using real-time polymerase chain reaction. RESULTS: Expression levels of NF-κB1, NF-κB2, and Rel genes were found to be deregulated. CONCLUSION: These results could be accepted as specific gene traces to radiation-induced leukemia or as potential candidates for new diagnostic biomarker studies. Larger experiments and non-exposed control malignant cell populations are needed to clarify these suggestions.

ABSTRACT

BACKGROUND/AIM: To detect specific molecular changes of DNA level in primary autism patients by using whole genome CGH array technology. MATERIALS AND METHODS: A cohort of 35 primary autism patients received clinical genetic testing by using an oligonucleotide-based CGH array platform to test for submicroscopic genomic deletions and duplications. Fluorescent in situ hybridization was performed in seven patients for confirmation of the results. RESULTS: We found 16p13.11 deletion in thirteen patients, 16p11.2 deletion in twelve patients, 1q21.1 deletion in ten patients, 2q21.1q21.2 deletion in eight patients, and 8p23.1 deletion in seven patients. CONCLUSION: Our study indicates that genes in 16p13.11, 16p11.2, 1q21.1, 2q2l.1q21.2, and 8p23.1 loci are potential predisposition and new suspicious regions for primary autism. Deletion's in these regions should be investigated in further studies to understand pathogenesis of primary autism.
