The alpha block of the human and chimpanzee major histocompatibility complex (MHC) class I genomic region contains 10 to 11 duplicated MHC class I genes, including the HLA/Patr-A, -G, and -F genes. In comparison, the alpha block of the rhesus macaque (Macaca mulatta, Mamu) has an additional 20 MHC class I genes within this orthologous region. The present study describes the identification and a...

Abstract Background Acute myeloid leukemia represents the highest percentage of all adult acute variants. Runt-related transcription factor1 ( RUNX1 ), a factor with known tumor suppressor function, was recently reported as promoter in (AML). We investigated role gene expression level Egyptian AML patients and delineated its clinical significance. Results measured using reverse transcription-qu...

Sequence database searching methods such as BLAST, are invaluable for predicting molecular function on the basis of sequence similarities among single regions of proteins. Searches of whole databases however, are not optimized to detect multiple homologous regions within a single polypeptide. Here we have used the prospero algorithm to perform self-comparisons of all predicted Drosophila melano...

Fanconi Anemia (FA) is an autosomal recessive syndrome characterized by congenital abnormalities, progressive bone marrow failure and Fanconi anemia complementation group A (FANCA) is also a potential breast and ovarian cancer susceptibility gene. A novel allele with tandem duplication of 13 base pair sequence in promoter region was identified. To investigate whether the 13 base pair sequence o...

Acute myeloid leukemia with a FLT3 internal tandem duplication (FLT3/ITD) mutation is an aggressive hematologic malignancy with a generally poor prognosis. It can be successfully treated into remission with intensive chemotherapy, but it routinely relapses. At relapse, the blasts tend to have higher mutant allelic ratios and, in vitro, are more addicted to the aberrant signaling from the FLT3/I...
