Malignant melanoma is between the cancer types that most have been increased in the last decades. When it is early detected, chances of cure through surgical excisions with secure margins are high. However, advanced cases of melanoma are resistant to all types of therapies; thus, one of the most challenges for melanoma research is the identification of molecular targets to further develop new treatment strategies.The ability to blockade the development of a tumor, depends on better understanding of cellular and molecular pathways that operate in the tumor microenvironment. A chronic and persistent inflammation contributes to cancer development, and, even tumors that are not epidemiologically linked to pathogens, they present inflammatory components in their microenvironment. The Kallicrein-Kinin system (KKS) is responsible for many biological effects like vasodilatation, modulation of pain and inflammation, capillary permeability increase, contraction and relaxation of the smooth muscles and cell proliferation. The kinin B1 receptor is well related to inflammatory processes, but the involvement of the KKS in cancer development is not well described in the literature. A recent study about the expression of the B1 and B2 receptors in lung cancer showed a modulation on the expression of these receptors in different subtypes of lung cancer. Regarding to melanoma, studies relating the involvement of the KKS in melanoma development is still not available. Thus, the aim of this work is evaluate the participation of the kinin B1 receptor as well as cell signaling pathways that might be involved in melanoma progression and metastasis. Our results might contribute to the identification of genetic mechanisms and signaling pathways that drive tumor progression, which is extremely important for designing rational therapies in the future.
