Readthrough of premature termination (stop) codons (PTC) is a new approach to treatment of genetic diseases. We recently reported that readthrough of PTC in cells from some xeroderma pigmentosum complementation group C (XP-C) patients could be achieved with the aminoglycosides geneticin or gentamicin. We found that the response depended on several factors including the PTC sequence, its location within the gene and the aminoglycoside used. Here, we extended these studies to investigate the effects of other aminoglycosides that are already on the market. We reasoned that topical treatment could deliver much higher concentrations of drug to the skin, the therapeutic target, and thus increase the therapeutic effect while reducing renal or ototoxicity in comparison with systemic treatment. Our prior clinical studies indicated that only a few percent of normal
XPC
expression was associated with mild clinical disease. We found minimal cell toxicity in the XP-C cells with several aminoglycosides. We found increased
XPC
mRNA expression in PTC-containing XP-C cells with
G418
, paromomycin, neomycin and kanamycin and increased
XPC
protein expression with
G418
. We conclude that in selected patients with XP, topical PTC therapy can be investigated as a method of personalized medicine to alleviate their cutaneous symptoms.
