Chimeric genes, which form through the genomic fusion of two protein-coding genes, are a significant source of evolutionary novelty in Drosophila melanogaster. However, the propensity of chimeric genes to produce adaptive phenotypic changes is not fully understood. Here, we describe the chimeric gene Quetzalcoatl (Qtzl; CG31864), which formed in the recent past and swept to fixation in D. melan...
We have designed and constructed a novel chimeric protein that consisted of a single domain of protein A and luciferase derived from sea-firefly Vargula hilgendorfii with the goal of obtaining a heterofunctional immunological tool. The structural gene of luciferase was fused to the 3' terminus of the D domain gene of protein A with/without a short linker of five amino acids. The resulting const...
The classic organization of a gene structure has followed the Jacob and Monod bacterial gene model proposed more than 50 years ago. Since then, empirical determinations of the complexity of the transcriptomes found in yeast to human has blurred the definition and physical boundaries of genes. Using multiple analysis approaches we have characterized individual gene boundaries mapping on human ch...
Chromosome translocations found in neoplasms often result in the creation of hybrid genes encoding chimeric proteins. Desmoplastic small round cell tumor (DSRCT) is a recently described aggressive malignancy associated with a unique chromosomal translocation t(11;22)(p13;q12). This translocation has recently been characterized, revealing the rearrangement and fusion of the WT1 gene on chromosom...
The Mycobacterium tuberculosis (M. tb) antigens encoded by the 6 kDa early secretory antigenic target (esat-6) and antigen 85A (ag85a) genes are known to exert protective effects against tuberculosis in animal models. In addition, these antigens represent vaccine components that were tested in early human clinical trials. In the present study, a chimeric DNA vaccine was constructed that contain...
UNLABELLED Gene fusion is a common event in cancer. The fusion RNA and protein products often play causal roles in tumorigenesis and therefore represent ideal diagnostic and therapeutic targets. Formerly, fusion chimeric products in cancer were thought to be produced solely by chromosomal translocation. Here, we show that a chimeric SLC45A3-ELK4 RNA is generated in the absence of chromosomal re...
UNLABELLED Gene fusions and their chimeric products are common features of neoplasia. Given that many cancers arise by the dysregulated recapitulation of processes in normal development, we hypothesized that comparable chimeric gene products may exist in normal cells. Here, we show that a chimeric RNA, PAX3-FOXO1, identical to that found in alveolar rhabdomyosarcoma, is transiently present in c...
To enhance the natural plant resistance and to evaluate the antimicrobial properties of phylloplanin against blue mold, we have expressed a synthetic chimeric native-phylloplanin-GFP protein fusion in transgenic Nicotiana tabacum cv. KY14, a cultivar that is highly susceptible to infection by Peronospora tabacina. The coding sequence of the tobacco phylloplanin gene along with its native signal...
The Philadelphia (Ph) translocation t(9;22)(q34;q11) occurs frequently in chronic myeloid leukemia (CML) but is less common in acute lymphoblastic leukemia (ALL) and rare in acute myeloid leukemia (AML). In most cases of CML and some cases of Ph+ ALL the protooncogene ABL from 9q34 is translocated to the breakpoint cluster region (bcr) of the BCR gene at 22q11 to form a chimeric gene encoding a...
Brain drug targeting technology is based on the application of four gene technologies that enable the delivery of drugs or genes across the blood-brain barrier (BBB) in vivo. I) Genetic engineering is used to produce humanized monoclonal antibodies that target endogenous BBB transporters and act as vectors for delivery of drugs or genes to the human brain. The conjugate of a neurotherapeutic an...
