Natural melanin nanoparticles (MNPs) extracted from Sepia officinalis: A cost-effective, chemo-photothermal, synergistic nanoplatform for osteosarcoma treatment

Osteosarcoma conventional chemotherapeutics are known for their side effects, limited options, and induction of drug resistance. This creates the need to develop new therapeutics capable of effectively destroying cancer cells with low toxicity, improving

Pro-Oxidant Properties of Melanosomal Melanin from Melanoma Origin [PDF]

, 2006
Melanoma cells, in comparison to normal melanocytes, contain higher concentrations of redox active species and yet are inefficient in mediating oxidative stress.

N-methyl –D-aspartate receptor stimulation activates tyrosinase and promotes melanin synthesis in the ink gland of the cuttlefish Sepia officinalis through the nitric oxide/cGMP signal trasduction pathway.

, 2000
The tyrosinase-catalyzed conversion of l-tyrosine to melanin represents the most distinctive biochemical pathway in the ink gland of the cuttlefish Sepia officinalis; however, the molecular mechanisms underlying its activation have remained so far ...

The ink gland of Sepia officinalis as biological model for investigations of melanogenesis

, 1997
The peculiar and complex organization of melanin in an invertebrate such as Sepia officinalis is surprising and could provide the basis for understanding the process in more evolved systems such as that of ...
