Abstract

Fibroblast cultures of 16 basal cell epithelioma (basalioma, BCE) patients with an unusu- ally young age at onset of disease (29-51 years; 42.5 +-7.04), and healthy normal controls (27-55 years; 40.73 +-9.52) were studied for chromosome instability induced by ultraviolet rays (UV). We used an UV source that emitted predominantly UV-A and UV-B at an intensity of 375 J/m2 and evaluated the induction of micronuclei (MN) and sister chromatid exchange (SCE). Young basalioma patients and normal controls showed no significant differences in MN and SCE frequencies, neither with respect to spontaneous nor to UV-induced values (MN spontaneous: 10.80 +- 5.65 vs.11.32 +- 8.21; UV-induced increase: 7.36 +- 4.40 vs. 9.93 +- 7.55; SCE spontaneous: 10.28 +- 1.61 vs. 10.72 +- 1.09; UV-induced increase: 7,30 +-2.19 vs. 7.55 +-2,14). We conclude from these data that an enhanced UV sensitivity as observed in cells from patients with cutaneous malignant melanoma and xeroderma pigmentosum is not a constitutive risk factor in basalioma patients.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
