The results of the observed osteo-inductive effect of Dox were further confirmed by gene expression analyses of osteogenic-related markers assessed by qPCR after the pretreatment with IL-17 (0 and 10 ng/mL) for three days and further cultivation in GM (control) or OM for seven days in the presence or absence of Dox (100 ng/mL). The gene discussed is IL17A; the disease is ocular melanoma.
