Expression data from actinic lentigines in European volunteers. Expression data from actinic lentigines in European volunteers

Actinic lentigines (AL) are very common hyperpigmented lesions that develop on chronically sun-exposed skin and represent a visible sign of skin ageing. In this study, a homogeneous group of advanced AL lesions was selected using epiluminescence imaging and pigmented pattern scoring. Gene expression profiling was performed on AL compared with adjacent non lesional (NL) skin. Overall design: Thirteen European women aged 51-67 years, phototype II-III were included in the study. Pairs of 3-mm biopsies (AL lesion and adjacent NL skin) were obtained on the back of hands from each volunteer.
