By contrast, we observed that the majority of the Vav2/Vav3-dependent transcripts previously found to be involved in the lung-specific metastasis of breast cancer cells was also present in the Vav-dependent transcriptome of TPA-stimulated skin (Inhba [ID number: 16323], Ptgs2 [ID number: 19225], Tacstd2 [ID number: 56753]; Figure S8) [17]. The gene discussed is PTGS2; the disease is breast carcinoma.
