EphA2 is phosphorylated on serine 897 (S897) in response to growth factors such as epidermal growth factor (EGF) and on tyrosine 588 (Y588) in response to its ligand ephrinA1, causing different cellular responses. In this study, we show that the actin-binding protein Filamin A forms a complex with EphA2 and promotes its S897 phosphorylation and glioblastoma cell proliferation. Suppression of Filamin A expression by siRNAs inhibited glioblastoma cell proliferation induced by EGF stimulation or overexpression of EphA2.

We observed that photoexcitation of IaNaR produced the distorted 13-cis retinal chromophore in the presence of Na+, while the structural distortion was significantly relaxed in the absence of Na+. This structural difference of the chromophore with/without Na+ was attributed to the Na+ binding to the protein, which alters the active site.

To know any factor which correlates with the effectiveness of finasteride, the polymorphism of androgen receptor (AR) gene was analyzed. Symptoms of the 488 MPB patients (18-62 y) before and after treatment with total dose of 10 mg or more of finasteride was typed by photographic method.

Objective: To perform the epidemiological study about a survey of psoriasis patients conducted in Japan for twenty years.
Methods: A sample of 28628 cases was collected from 148 dermatology centers throughout Japan.
