Exploring DNA damage responses in human cells with recombinant adenoviral vectors.
Recombinant adenoviral vectors provide efficient means for gene transduction in mammalian cells in vitro and in vivo. We are currently using these vectors to transduce DNA repair genes into repair deficient cells, derived from xeroderma pigmentosum (XP) patients. XP is an autosomal syndrome characterized by a high frequency of skin tumors, especially in areas exposed to sunlight, and, occasiona...
متن کاملOn the search for skin gene therapy strategies of xeroderma pigmentosum disease.
The introduction of genes through the skin has been an attractive and dynamic field of research in recent years. It gives the first gleam of hope in therapy for the human genetic diseases that mainly affect this tissue, such as patients that suffer from xeroderma pigmentosum, and who experience increased frequency of skin cancer. The first in vitro experiments were successful in correcting the ...
متن کاملUV-Induced Ubiquitylation of XPC Protein Mediated by UV-DDB-Ubiquitin Ligase Complex
The xeroderma pigmentosum group C (XPC) protein complex plays a key role in recognizing DNA damage throughout the genome for mammalian nucleotide excision repair (NER). Ultraviolet light (UV)-damaged DNA binding protein (UV-DDB) is another complex that appears to be involved in the recognition of NER-inducing damage, although the precise role it plays and its relationship to XPC remain to be el...
متن کاملHIV-Derived Lentiviral Vectors: Current Progress toward Gene Therapy and DNA Vaccination
Lentiviral vectors are promising gene delivery tools capable of transducing a variety of dividing and non-dividing cells, including pluripotent stem cells which are refractory for transduction by murine retroviruses. Although there is a growing debate on the safety of lentiviral vectors for gene transfer, in particular for those derived from human immunodeficiency viruses, type one (HIV-1) and ...
متن کاملDNA Damage and Repair in Human Cancer: Molecular Mechanisms and Contribution to Therapy-Related Leukemias
Most antitumour therapies damage tumour cell DNA either directly or indirectly. Without repair, damage can result in genetic instability and eventually cancer. The strong association between the lack of DNA damage repair, mutations and cancer is dramatically demonstrated by a number of cancer-prone human syndromes, such as xeroderma pigmentosum, ataxia-telangiectasia and Fanconi anemia. Notably...
