We have measured UVB (280–320 nm)-induced DNA damage in skin of individuals with different sensitivities to UVB irradiation as measured by minimal erythema dose (MED). The DNA damage was susceptible to cleavage byMicrococcus luteusUV endonuclease, which recognizes pyrimidine dimers in DNA. An alkaline agarose gel electrophoresis method was used to quantitate the number ofM. luteusUV endonuclease-sensitive sites in nonradioactive DNA from skin biopsies of 7 individuals irradiated with UVB (0–180 mJ· cm‒2). The production of sites correlated well with MED (correlation coefficient = 0.78). The slope of the dose response curve for the most UVB-sensitive individual (MED = 24 mJ · cm‒2) and for the least UVB-sensitive individual (MED = 146 mJ · cm‒2) were 11.5 × 10‒4and 2.6 × 10‒4sites per 1000 bases per mJ·cm‒2, respectively. The UVB-induced DNA damage was determined to be pyrimidine dimers by its susceptibility to cleavage byM. luteusUV endonuclease and its photoreactivability byEscherichia coliphotoreactivating enzyme.
