Nearly one-third of patients with acute myeloid leukemia have FMS-like tyrosine kinase 3 mutations and thus have poor survival prospects. Receptor tyrosine kinase anexelekto is critical for FMS-like tyrosine kinase 3 signaling and participates in FMS-like tyrosine kinase 3 inhibitor resistance mechanisms. Thus, strategies targeting anexelekto could prove useful for acute myeloid leukemia therap...
PURPOSE Obtaining direct and rapid proof of molecular activity in early clinical trials is critical for optimal clinical development of novel targeted therapies. SU11248 is an oral multitargeted kinase inhibitor with selectivity for fms-related tyrosine kinase 3/Flk2 (FLT3), platelet-derived growth factor receptor alpha/beta, vascular endothelial growth factor receptor 1/2, and KIT receptor tyr...
Using a long-span, paired-end deep sequencing strategy, we have comprehensively identified cancer genome rearrangements in eight breast cancer genomes. Herein, we show that 40%-54% of these structural genomic rearrangements result in different forms of fusion transcripts and that 44% are potentially translated. We find that single segmental tandem duplication spanning several genes is a major s...
The etiology of acute myeloid leukemia (AML) is largely unknown. Biologic and epidemiologic data implicate exogenous toxicants, including cytotoxic drugs, benzene, radiation, and cigarette smoking. Allelic variation in genes encoding enzymes such as NADP(H) quinone oxidoreductase (NQO1) and glutathione S-transferase T1 (GSTT1) that metabolize environmental toxicants predispose to subtypes of AM...
Zinc (Zn) and cadmium (Cd) hyperaccumulation may have evolved twice in the Brassicaceae, in Arabidopsis halleri and in the Noccaea genus. Tandem gene duplication and deregulated expression of the Zn transporter, HMA4, has previously been linked to Zn/Cd hyperaccumulation in A. halleri. Here, we tested the hypothesis that tandem duplication and deregulation of HMA4 expression also occurs in Nocc...
introduction: about half of acute myeloid leukemia (aml) adult patients have no cytogenetic abnormalities as a main determinant of complete remission after treatment, so other markers are needed such as flt3-itd (fms-like tyrosine kinase3-internal tandem duplication) mutations in patients with normal karyotype. the objective of this study was assessing the frequency of flt3-itd mutations and it...
Members of the disintegrin metalloproteinase (ADAM) family have important functions in regulating cell-cell and cell-matrix interactions as well as cell signaling. There are two major types of ADAMs: the somatic ADAMs (sADAMs) that have a significant presence in somatic tissues, and the testicular ADAMs (tADAMs) that are expressed predominantly in the testis. Genes encoding tADAMs can be furthe...
Encapsulated Haemophilus influenzae type b produce nonencapsulated variants at high frequency (0.1-0.3%). Cosmid cloning was used to investigate the genetic mechanism responsible for this instability. Analysis of three independently derived cosmid clones showed that the b+ parental strain contains an 18-kilobase tandem duplication of genes involved in type b capsule expression. Loss of one comp...
The set of all \(q\)-ary strings that do not contain repeated substrings length \({\le\! 3}\) (i.e., the form \(a a\), b a b\), and c c\)) constitutes code correcting an arbitrary number tandem-duplication mutations 3}\). In other words, any two such are non-confusable in sense they cannot produce same string while evolving under tandem duplications We demonstrate this is asymptotically optimal...
