Imaging reporter gene expression in living subjects with various imaging modalities is a rapidly accelerating area of research. Applications of these technologies to cancer research, gene therapy, and transgenic models are rapidly expanding. We report construction and testing of several triple fusion reporter genes compatible with bioluminescence, fluorescence and positron emission tomography (...

CTLA4 and CD28 are co-regulatory receptors with opposite roles in T-cell signaling. By RNA sequencing, we identified a fusion between the two genes from partial gene duplication in a case of angioimmunoblastic T-cell lymphoma. The fusion gene, which codes for the extracellular domain of CTLA4 and the cytoplasmic region of CD28, is likely capable of transforming inhibitory signals into stimulato...

We developed an innovative hybrid sequencing approach, IDP-fusion, to detect fusion genes, determine fusion sites and identify and quantify fusion isoforms. IDP-fusion is the first method to study gene fusion events by integrating Third Generation Sequencing long reads and Second Generation Sequencing short reads. We applied IDP-fusion to PacBio data and Illumina data from the MCF-7 breast canc...

background: single domain antibodies from camel heavy chain antibodies (vhh or nanobody), are advantages due to higher solubility, stability, high homology with human antibody, lower immunogenicity and low molecular weight. these criteria make them candidates for production of engineered antibody fragments particularly in transgenic animals. objective: to study the development of transgenic chi...

BACKGROUND Characterization of novel fusion genes in acute leukemia is important for gaining information about leukemia genesis. We describe the characterization of a new ETV6 fusion gene in acute myeloid leukemia (AML) FAB M0 as a result of an uncommon translocation involving chromosomes 12 and 15. METHODS The ETV6 locus at 12p13 was shown to be translocated and to constitute the 5' end of t...

BACKGROUND t(12;21) (p12;q22) and t(9;22) (q34;q11) translocations have prognostic significance in acute lymphoblastic leukemia (ALL). The fusion genes TEL/AML1 y BCR/ABL, generated by these translocations, can be easily detected using molecular biology technique. AIM To study the frequency of TEL/AML1 y BCR/ABL fusion genes in children with ALL. MATERIAL AND METHODS Fifty-six children with...

BACKGROUND Parathyroid hormone is an 84-amino acid peptide secreted by the parathyroid glands. Its physiological role is maintenance of normal serum calcium level and bone remodeling. Biological activity of this hormone is related to N-terminal 1-34 amino acids. The recombinant form of hormone (1-34) has been approved for treatment of osteoporosis from 2002. In this study, a novel fusion partne...

Recently, gene fusions between the androgen responsive gene TMPRSS2 and members of the ETS-family of DNA-binding transcription factor genes were found in prostate cancer. Recurrent fusions were identified between the 5'-noncoding region of TMPRSS2 and ERG, or less frequently ETV1 or ETV4, resulting in overexpression of normal or truncated ETS-proteins. Herein, we have analyzed a series of 50 pr...

The translocation liposarcoma (TLS) gene is fused to the ETS-related gene (ERG) in human myeloid leukemia, resulting in the generation of a TLS-ERG protein. We demonstrate that both TLS and the TLS-ERG leukemia fusion protein bind to RNA polymerase II through the TLS N-terminal domain, which is retained in the fusion protein; however, TLS recruits members of the serine-arginine (SR) family of s...

RNA-sequencing and tailored bioinformatic methodologies have paved the way for identification of expressed fusion genes from the chaotic genomes of solid tumors. We have recently successfully exploited RNA-sequencing for the discovery of 24 novel fusion genes in breast cancer. Here, we demonstrate the importance of continuous optimization of the bioinformatic methodology for this purpose, and r...
