Steroidogenesis in the brain of Sepia officinalis and Octopus vulgaris.
Di Cristo C, Di Donato P, Palumbo A, d'Ischia M, Paolucci M, Di Cosmo A. Di Cristo C, et al. Front Biosci (Elite Ed). 2010 Jan 1;2:673-83. doi: 10.2741/e127. Front Biosci (Elite Ed). 2010. PMID: 20036911
Binding experiments seem to assign a functional role to the androgens in the brain of cephalopods. According to the present results, the absence of any progesterone binding moiety supports the hypothesis that progesterone may be a metabolite product along the steroi …

Conservative nature of oestradiol signalling pathways in the brain lobes of octopus vulgaris involved in reproduction, learning and motor coordination.
De Lisa E, Paolucci M, Di Cosmo A. De Lisa E, et al. J Neuroendocrinol. 2012 Feb;24(2):275-84. doi: 10.1111/j.1365-2826.2011.02240.x. J Neuroendocrinol. 2012. PMID: 21988192
In the present study, using a combination of molecular and imaging techniques, we found that oestradiol up-regulated O. vulgaris gonadotrophin-releasing hormone (Oct-GnRH) and O. vulgaris oestrogen receptor (Oct-ER) mRNA levels in the olfactory lobes; in turn, Oct-ER mRNA …
