Ezrin-radixin-moesin-binding phosphoprotein 50 (EBP50) is a postsynaptic density-95/disc-large/zonula occludens-1 (PDZ) homologous domain-containing protein that is involved in cell signaling. EBP50 regulates cell apoptosis, proliferation and invasion. In the present study, the prognostic impact factor of EBP50 expression was evaluated using a quantum dot (QD)-based assay and immunohistochemist...
BACKGROUND Mutations in the p53 tumor suppressor gene (also known as TP53) have been detected in a wide variety of human cancers. In breast cancer, the presence of p53 gene alterations has been associated with worse prognosis. PURPOSE We compared a complementary DNA (cDNA)-based sequencing method and an immunohistochemical (IHC) method for their abilities to detect p53 mutations in breast can...
BACKGROUND HER2 testing in gastric cancer differs from testing in breast cancer because of inherent differences in tumor biology; gastric cancer more frequently shows HER2 heterogeneity and incomplete membrane staining. The aim of the present study was to evaluate the frequency and accuracy of detection of HER2 expression by application of standard criteria in Japanese patients with gastric can...
Fluorescent in-situ hybridization (FISH) and immunohistochemistry (IHC) constitute a pair of complimentary techniques for detecting gene amplification and overexpression, respectively. The advantages of IHC include relatively cheap materials and high sample durability, while FISH is the more accurate and reproducible method. Evaluation of FISH and IHC images is still largely performed manually,...
The purpose of this study was to investigate the effects of mild systemic hypoxia on inner haircell (IHC) and outer haircell (OHC) function. A number of studies have explored the effects of anoxia/hypoxia and ischemia of the inner ear [e.g. 1,2,3,4,5] but have not addressed whether there is a dissociation between IHC and OHC function during such an insult. To monitor OHC activity we recorded ot...
Twenty seven dog brain tissues were examined for rabies infection by fluorescent antibody technique, immunohistochemistry and Hemi-Nested Reverse Transcriptase (HnRT-PCR). 16 (59.25%) dogs were confirmed to be rabid by FAT and HnRT-PCR assay while 15 samples were positive by immunohistochemistry (IHC). Sensitivities of HnRT-PCR and IHC were 100% and 94.11% respectively whereas both approaches d...
