Genetic experiments in zebrafish identify neuropeptide VF (NPVF) signaling and NPVF-expressing neurons as a novel vertebrate hypothalamic sleep-promoting system that is functionally conserved with invertebrates.

A chronic stressor prior to mating has lasting negative consequences on the fertility and fecundity of female rats, which can be prevented by blocking a single hypothalamic reproductive inhibitory hormone.

Experiments using zebrafish identify a novel sleep-promoting neuronal circuit in which hypothalamic NPVF neurons promote sleep via the hindbrain serotonergic raphe nuclei, which promote sleep in both zebrafish and mice.
A coordinated humoral immune response that includes recognition, effector and cytotoxic factors engages the cell-mediated immune response to defend a snail against infection by schistosome parasites.

The development of diverse tooth shapes among vertebrates, from sharks to mammals, is a highly conserved process, utilising a similar dental signalling centre for more than 400 million years.

A cysteine-rich domain within the Smoothened receptor may represent a novel therapeutic target for cancers caused by abnormal functioning of the Hedgehog signaling pathway.
The crystal structure of Norrie Disease Protein in complex with the extracellular cysteine-rich domain of Frizzled4 receptor and sucrose octasulfate reveals binding sites for Frizzled4, low density lipoprotein receptor related protein 5/6, and proteoglycan.
