Targeting gene therapy vectors to CNS malignancies.
Gene therapy offers significant advantages to the field of oncology with the addition of specifically and uniquely engineered mechanisms of halting malignant proliferation through cytotoxicity or reproductive arrest. To confer a true benefit to the therapeutic ratio (the relative toxicity to tumor compared to normal tissue) a vector or the transgene it carries must selectively affect or access ...
متن کاملTERT Promoter Mutations in Thyroid Cancer.
Two mutations (C228T and C250T) in the promoter region of the telomerase reverse transcriptase (TERT) have recently been described in different types of cancer including follicular cell-derived thyroid cancer (TC). In this paper, we reviewed the rates of these mutations in different types and subtypes of TC, their association with a number of clinical and histopathological features and outcome ...
متن کاملCell encapsulation technology as a therapeutic strategy for CNS malignancies.
Gene therapy using viral vectors has to date failed to reveal its definitive clinical usefulness. Cell encapsulation technology represents an alternative, nonviral approach for the delivery of biologically active compounds to tumors. This strategy involves the use of genetically engineered producer cells that secrete a protein with therapeutic potential. The cells are encapsulated in an immunoi...
متن کاملNFκB drives TERT promoter reactivation in cancer
Transformed cells from 80 to 85% of human cancers display measureable levels of active TERT, the reverse transcriptase subunit of telomerase which is essential for growth and survival of these cells. It is well known that the TERT promoter is transcriptionally silenced in development soon after stem cells loose stemness and differentitae. Although interesting from the point of view of regenerat...
متن کاملUnderstanding TERT Promoter Mutations: A Common Path to Immortality.
Telomerase (TERT) activation is a fundamental step in tumorigenesis. By maintaining telomere length, telomerase relieves a main barrier on cellular lifespan, enabling limitless proliferation driven by oncogenes. The recently discovered, highly recurrent mutations in the promoter of TERT are found in over 50 cancer types, and are the most common mutation in many cancers. Transcriptional activati...
