Currently, skin Cancer is one of the most prevalent diseases in the world and one of the most commonly diagnosed malignancies. The main molecular pathways involved in the development of skin Cancer are the Hedgehog (Hh) pathway, which is associated with signs of proliferation, growth and control of cell fate in many tissues via the EGFR receptor, which is associated with cell differentiation to be related to tumorigenesis and the apoptosis pathway, which is common to all types of Cancer. Multifunctional therapies that combine antitumor drugs and other molecules, such as siRNAs, have been widely studied for Cancer treatment, aiming at therapeutic action in different pathways of disease development. Nanostructured Lipid Carriers (CLN) are considered ideal for the topical release of drugs because of their interaction with cutaneous tissue. In this project, a CLN will be developed and optimized by the high pressure homogenization method and preliminary studies will be carried out on the scheduling of the production process of this CLN, for the purpose of production in larger scales (Scaling up). This CLN will have a multifunctional character, containing a pool of specific siRNAs and an antitumor, namely 5-fluorouracil, aiming at a therapy that inhibits the different molecular pathways of skin cancer, thus obtaining a synergistic action, which will culminate in reduction/remission of the skin tumor. It will be characterized in physical and chemical morphological aspects, evaluated in conventional cellular assays of cell viability and transfection, as well as complexation with the siRNAs. In an unpublished form, an alternative animal testing will be performed for permeation and retention tests on human skin using the hOSEC model. Finally, a xenographic animal model will be developed with the purpose of evaluating the antitumor activity of the multifunctional system developed. (AU)
