INTRODUCTION Hypodontia, hypohidrosis, sparse hair and characteristic faces are the main characters of X-linked hypohidrotic ectodermal dysplasia (XLHED) which is caused by genetic ectodysplasin A (EDA) deficiency. Heterozygous female carriers tend to have mild to moderate XLHED phenotype, even though 30% of them present no obvious symptom. METHODS A large Chinese XLHED family was reported an...

This paper summarizes a strategy for development of an EDA (Electronic Design Automation) tool which is aimed to support the design of future nano-circuits. The problem with the existing EDA tools is that they do not explicitly consider reliability as a design criterion. Most of the tools that do consider reliability are not intended for the nanoelectronic industry and are very limited in the t...

The mouse hair coat comprises protective "primary" and thermo-regulatory "secondary" hairs. Primary hair formation is ectodysplasin (Eda) dependent, but it has been puzzling that Tabby (Eda(-/y)) mice still make secondary hair. We report that Dickkopf 4 (Dkk4), a Wnt antagonist, affects an auxiliary pathway for Eda-independent development of secondary hair. A Dkk4 transgene in wild-type mice ha...

X-linked hypohidrotic ectodermal dysplasia (XLHED) is the most common of the ectodermal dysplasias, with a classic presentation of hypodontia, hypohidrosis, hypotrichosis and secretory gland hypoplasia. Mutations in the ectodysplasin gene (EDA) underlie XLHED with nearly 200 different mutations reported. EDA encodes a type 2 transmembrane protein of the TNF family (EDAA1), the active form of wh...

BACKGROUND The Eda-A1-Edar signaling pathway is involved in the development of organs with an ectodermal origin, including teeth. In mouse, mutants are known for both the ligand, Eda-A1 (Tabby), and the receptor, Edar (Downless). The adult dentitions of these two mutants have classically been considered to be similar. However, previous studies mentioned differences in embryonic dental developme...

Ectodermal dysplasias (ED) are uncommon genetic disorders resulting in abnormalities in ectodermally derived structures. Many ED-associated genes have been described, of which ectodysplasin-A (EDA) is one of the more common. The NF-κB essential modulator (NEMO encoded by the IKBKG gene) is unique in that mutations result in severe humoral and cellular immunologic defects in addition to ED. We d...

BACKGROUND Streptozotocin (STZ) has served as an agent to generate an Alzheimer's disease (AD) model in rats, while edaravone (EDA), a novel free radical scavenger, has recently emerged as an effective treatment for use in vivo and vitro AD models. However, to date, these beneficial effects of EDA have only been clearly demonstrated within STZ-induced animal models of AD and in cell models of A...

Amyloid protein can damage nerve cells through a variety of biological mechanisms including oxidative stress, alterations in calcium homeostasis, and proapoptosis. Edaravone, a potent free radical scavenger possessing antioxidant effects, has been proved neuroprotective effect in stroke patients. The current study aimed to investigate the effects of EDA in an Aβ-induced rat model of AD, by stud...

Ectodysplasin A (Eda), a member of the tumour necrosis factor superfamily, plays an important role in ectodermal organ development. An EDA mutation underlies the most common of ectodermal dysplasias, that is X-linked hypohidrotic ectodermal dysplasia (XLHED) in humans. Even though it lacks a developmental function, the role of Eda during the postnatal stage remains elusive. In this study, we fo...
