  • Cyanobacteria in cosmetics: a natural alternative for anti-aging ingredients
    Publication . Morone, Janaína; Lopes, Graciliana; Oliveira, Beatriz; Vasconcelos, Vítor; Martins, Rosario
    Being exposed to endogenous and exogenous stressors, and being the body’s external defense line, skin protection is of pivotal importance, in order to maintain morphological and physiologic integrity and health. Fostering by individual psychological comfort, esthetic performance, and young appearance, along with motivation for natural products with less side effects and sustainable production, consumer’s demands drive the cosmetic industry into the relentless pursuit for innovation. In this context, cyanobacteria enforce as a promising source of ingredients with cosmetic potential. With the ability to withstand adverse conditions for survival, the adaptation to extreme environments is reflected in the production of compounds with moisturizing, photoprotective, antioxidant, and whitening potential, all attributes required in cosmetics, namely in anti-aging products. In this chapter, we will focus on the interconnection between cyanobacteria and skin, by presenting the main applications of these organisms in skincare products.

  • Marine Cyanobacteria Compounds with Anticancer Properties: Implication of Apoptosis
    Publication . Martins, Rosário; Costa, Margarida
    Marine cyanobacteria have been proved to be an important source of potential anticancer drugs. Although several compounds were found to be cytotoxic to cancer cells in culture, the pathways by which cells are affected are still poorly elucidated. For some compounds, cancer cell death was attributed to an implication of apoptosis through morphological apoptotic features, implication of caspases and proteins of the Bcl-2 family, and other mechanisms such as interference with microtubules dynamics, cell cycle arrest and inhibition of proteases other than caspases.
