DUSP1 and SOX2 expression determine squamous cell carcinoma of the salivary gland progression.

Salivary gland squamous cell carcinomas (SG-SCCs) constitute a rare type of head and neck cancer which is linked to poor prognosis. Due to their low frequency, the molecular mechanisms responsible for their aggressiveness are poorly understood. In this work we studied the role of the phosphatase DUSP1, a negative regulator of MAPK activity, in controlling SG-SCC progression.

[Incontinentia pigmenti: three new cases that demonstrate it is not only a matter of women].

Incontinentia pigmenti is a rare, dominantly X-linked genodermatosis characterized by multisystemic involvement that is lethal prenatally in the majority of affected males and shows great clinical variability when it is expressed in women. Recently it has been shown that mutations of the gene NEMO/IKK-g located in Xq28 cause the expression of the disease, being only one mutation responsible for approximately 80 % of the cases. The diagnosis of incontinentia pigmenti is performed based on clinical features and family history with the support of histological findings.
