title: Enhanced expression of common fragile site with occupational exposure to pesticides.
abstract: The expression of common fragile sites (FS), induced by aphidicolin, in subjects with occupational history of exposure to pesticides has been studied. Results showed a higher frequency of FS in exposed subjects; in particular, there was an elevated expression of FS at the cancer breakpoints 3p14, 5q31, 7q22, 7q32, 14q24, and 16q22, involved in leukemias and non-Hodgkin's lymphoma. Moreover, the frequency of breaks in chromosomal bands carrying oncogenes or tumor suppressor genes involved in aberrations was significantly higher in exposed subjects at sites 1q25, 3p25, 7p22, 8q24.1, and 13q14.
