To confirm this observation, TLR3 messenger RNAs were analyzed by quantitative RT-PCR in a series of human malignant cell lines including one melanoma (T1), two ovarian carcinomas (IGR-OV1 and SKOV3), one endocervical carcinoma (HeLa), one prostate carcinoma (LNCaP). This evidence concerns the gene TLR3 and melanoma.
