Repair of UV photolesions in xeroderma pigmentosum group C cells induced by translational readthrough of premature termination codons.
About 12% of human genetic disorders involve premature termination codons (PTCs). Aminoglycoside antibiotics have been proposed for restoring full-length proteins by readthrough of PTC. To assess the efficiency of readthrough, we selected homozygous and compound heterozygous skin fibroblasts from xeroderma pigmentosum (XP) patients with different PTCs in the XPC DNA repair gene. XP patients hav...
متن کاملThe unfolded protein response affects readthrough of premature termination codons
One-third of monogenic inherited diseases result from premature termination codons (PTCs). Readthrough of in-frame PTCs enables synthesis of full-length functional proteins. However, extended variability in the response to readthrough treatment is found among patients, which correlates with the level of nonsense transcripts. Here, we aimed to reveal cellular pathways affecting this inter-patien...
متن کاملRegulation of DNA repair in serum-stimulated xeroderma pigmentosum cells
The regulation of DNA repair during serum stimulation of quiescent cells was examined in normal human cells, in fibroblasts from three xeroderma pigmentosum complementation groups (A, C, and D), in xeroderma pigmentosum variant cells, and in ataxia telangiectasia cells. The regulation of nucleotide excision repair was examined by exposing cells to ultraviolet irradiation at discrete intervals a...

متن کاملRepair of oxidative DNA base lesions induced by fluorescent light is defective in xeroderma pigmentosum group A cells.
Fluorescent light (FL) has been shown to generate free radicals within cells, however, the specific chemical nature of DNA damage induced by FL has not previously been determined. Using gas chromatography/isotope dilution mass spectrometry, we have detected induction of the oxidative DNA lesions 5-hydroxycytosine (5-OH-Cyt), 2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyGua) and 4, 6-diamino...
