Sodium channel, voltage-gated, type IX, alpha subunit

PN1, Nav1.7, Gdn, SCN9A, SERPINE2
This gene encodes a voltage-gated sodium channel which plays a significant role in nociception signaling. Mutations in this gene have been associated with primary erythermalgia, channelopathy-associated insensitivity to pain, and paroxysmal extreme pain disorder.

PURPOSE: Altered expression of serine protease inhibitor peptidase inhibitor clade E member 2 (SERPINE2) associates with human cancer development and progression; thus, this study investigated SERPINE2 expression in gastric cancer tissues for association with clinicopathological and survival data from the patients and then investigated the role of SERPINE2 in gastric cancer cells in vitro.

Review
New
Impact
Woods et al., Cambridge, United Kingdom. In Lancet Neurol, Jun 2014
For example, the voltage-gated sodium ion channel Nav1.7 is expressed selectively in sensory and autonomic neurons; inactivating mutations in SCN9A, which encodes Nav1.7, result in congenital insensitivity to pain, whereas gain-of-function mutations in this gene produce distinct pain syndromes such as inherited erythromelalgia, paroxysmal extreme pain disorder, and small-fibre neuropathy.

Review
New
Bennett et al., Oxford, United Kingdom. In Pract Neurol, May 2014
A recent and significant advance is the finding that a proportion of cases labelled as idiopathic SFN are in fact associated with gain of function mutations of the voltage-gated sodium channels Nav1.7 and Nav1.8 (encoded by the genes SCN9A and SCN10A, respectively).

Abriel et al., Bern, Switzerland. In Handb Exp Pharmacol, Dec 2013
Using two different mouse models, one with a specific knockout of Nedd4-2 in sensory neurons and another where Nedd4-2 was overexpressed with the use of viral vectors, it was demonstrated that the neuropathy-linked neuronal hyperexcitability was the result of Nav1.7 and Nav1.8 overexpression due to Nedd4-2 downregulation.
