Salt Flat Pigments: A New Era of Breast Cancer Biomedicines?

Pinterest LinkedIn Tumblr +

Could ancient salt-loving microbes found only in salt flats herald a new kind of biomedicine? Could their sun-protective antioxidative reactions be harnessed in the development of new treatment options for hard-to-treat cancers like triple-negative breast cancer?

In today’s episode, we are transported to Spain to delve into the fascinating world of haloarchaeal carotenoids.

Join our Host Rachael Babin in conversation with Professor Rosa María Martínez-Espinosa, whose research group recently discovered the potent antioxidant activity of haloarchaeal carotenoids found in the Santa Pola salt flats, just outside of Alicante.

Rosa María Martínez-Espinosa

Rosa María Martínez is a Professor of Biochemistry and Molecular Biology, and Director of the Applied Biochemistry Research Group at the University of Alicante, in Spain.

Her interests lie in the characterisation of the molecular biology and biochemistry of enzymes involved in N cycle in haloarchaea and other extreme microbes as well as in the study of biomolecules that can be used as biomarkers for diagnosis or monitoring of diseases.
