  • Burkitt lymphoma is the most rapidly growing human tumor, and pathology reveals a high mitotic rate, a monoclonal proliferation of B cells, and a "starry-sky" pattern of benign macrophages that have engulfed apoptotic malignant lymphocytes. (msdmanuals.com)
  • Epstein-Barr virus (EBV) was the first recognized human tumor virus, but it is not the causative agent for the tumor in which it was discovered, Burkitt lymphoma. (cdc.gov)
  • Our finding that a coordinated interplay between the components of the DNA methylating machinery contributes to MYC-driven tumor maintenance highlights the potential of specific DNMTs for targeted therapies. (diagenode.com)
  • There is a low background incidence of BL worldwide (sBL), which is rarely associated with EBV and accounts for 1-2% of adult lymphoma in Western Europe and America, but eBL is associated with (EBV) in over 95% of cases and is predominant in the equatorial belt of Africa and other parts of the world where malaria is hyperendemic.

  • Assessment of F-MuLV-induced tumorigenesis reveals new candidate tumor genes including Pecam1, St7, and Prim2. (rochester.edu)
  • Deregulation of these expression programs has been linked to MYC's function in tumor initiation, progression, and survival. (cshlpress.com)
  • The authors also provide a detailed analysis of the role of MYC in tumor initiation and progression. (cshlpress.com)
  • We found that the expression of foreign antigens such as chicken ovalbumin (OVA) and green fluorescent protein (GFP) in Stat1-competent 291 cells led to immune responses that delayed tumor progression and improved survival of wild-type animals. (uni-muenchen.de)
  • Consistent with this, loss of foreign antigen inevitably led to accelerated tumor progression upon transfer into immunocompetent wild-type mice. (uni-muenchen.de)
  • Transfer of immunogenic 291-OVA-GFP lymphoma cells led to increased tumor progression without loss of foreign antigen upon transfer into IFN-γ-/- and Stat1-/- mice indicating that no selection of antigen loss-variants occurred in these mice. (uni-muenchen.de)
  • EVs were characterized by transmission electron microscopy and fluorescence nanoparticle tracking analysis, and EV surface protein profiles were analyzed by multiplex bead-based flow cytometry to identify tumor- or immune system-related EVs of AML, ALL, CLL, and healthy samples. (nature.com)
  • Insulin-like growth factor-1 receptor expression in pediatric tumors: " by RESUL KARAKUŞ, ESRA KARAKUŞ et al. (tubitak.gov.tr)
  • We aimed to determine the expression of IGF- 1R in di erent pediatric tumors and to shed light on possible new indications of anti-IGF-1R treatment approaches. (tubitak.gov.tr)
  • Two different studies explored gene-expression profiling by microarray technology as a tool to accurately diagnose Burkitt lymphoma (BL) and differentiate it from DLBCL due to the significant difference in prognosis and treatment approaches for these diseases. (medscape.com)
  • But a benign tumor can sometimes cause severe problems, such as in or near the brain. (medlineplus.gov)
  • Genital warts, which are a form of benign tumor of epithelial cells, are also caused by various strains of HPV. (wikipedia.org)
  • The main emphasis is on supervised machine learning methods for classification and prediction of tumor gene expression profiles. (lu.se)
  • In 2021, he was invited by IARC/WHO to assist in the revision of the Burkitt Lymphoma chapter in the WHO Classification of Tumours, 5th edition - Haematolymphoid Tumours . (cancer.gov)
