background and aims: ndv (newcastle disease virus) is one of the viruses that cause disease in avian with severe economic losses in the poultry industry in many countries. fusion protein (f) which plays a major role in the virus pathogenicity contains several regions that have a role in the fusion process. mutation in the sequence of hr1 & hr2 regions of this protein prevents fusion of the viru...

A sensitive dimerization assay for DNA binding proteins has been developed using gene fusion technology. For this purpose, we have engineered a gene fusion using protein A gene of Staphylococcus aureus and C gene, the late gene transactivator of bacteriophage Mu. The C gene was fused to the 3' end of the gene for protein A to generate an A-C fusion. The overexpressed fusion protein was purified...

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 ch...

background: the human aml1 gene, located on chromosome 21, can be fused to the aml1- eight-twenty-one (eto) oncoprotein on chromosome eight, resulting in a t(8;21)(q22;q22) translocation. acute myeloid leukemia (aml) associated with this translocation is considered a distinct aml with a favorable prognosis. due to the various incidences of the translocation, which is associated with geographic ...

Sarcomas are relatively rare malignancies and include a large number of histological subgroups. Based on morphology alone, the differential diagnoses of sarcoma subtypes can be challenging, but the identification of specific fusion genes aids correct diagnostication. The presence of individual fusion products are routinely investigated in Pathology labs. However, the methods used are time-consu...

Fusion genes are frequently observed in hematologic malignancies and soft tissue sarcomas, and are usually associated with chromosome abnormalities. Many of these fusion genes create in-frame fusion transcripts that result in the production of fusion proteins, and some of which aid tumorigenesis. These fusion proteins are often associated with disease phenotype and clinical outcome, and act as ...

Purpose: The TMPRSS2/ERG (T/E) fusion gene is present in half of all prostate cancer tumors. Fusion of the oncogenic ERG gene with the androgen-regulated TMPRSS2 gene promoter results in expression of fusionmRNAs inprostate cancer cells. The junction of theTMPRSS2andERG-derived portions of the fusion mRNA constitutes a cancer-specific target in cells containing the T/E fusion gene. Targeting th...

background: the wilms tumor 1 (wt1) gene is originally defined as a tumor suppressor gene and a transcription factor that overexpressed in leukemic cells. it is highly expressed in more than 80% of acute myeloid leukemia (aml) patients, both in bone marrow (bm) and in peripheral blood (pb), and it is used as a powerful and independent marker of minimal residual disease (mrd);we have determined ...
