Calmodulin levels in normal human thyroids and Graves' disease thyroids were measured by specific radioimmunoassay in the presence of ethyleneglycol-bis-(beta-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA). The calmodulin levels in tissues from patients with Graves' disease treated with thionamide drugs were significantly higher than those in normal tissues from euthyroid patients with sol...
The transcription factor p63 is central for epithelial homeostasis and development. In our model of epithelial to mesenchymal transition (EMT) in human prostate cells, p63 was one of the most down-regulated transcription factors during EMT. We therefore investigated the role of p63 in EMT. Over-expression of the predominant epithelial isoform ΔNp63α in mesenchymal type cells of the model led to...
Adoptive cell therapy (ACT) is a highly personalized cancer therapy that involves administration to the cancer-bearing host of immune cells with direct anticancer activity. ACT using naturally occurring tumor-reactive lymphocytes has mediated durable, complete regressions in patients with melanoma, probably by targeting somatic mutations exclusive to each cancer. These results have expanded the...
purpose: to report the histopathological diagnoses of recipient corneal buttons in patients undergoing penetrating keratoplasty. methods: in this observational case series, all recipient corneal specimens sent to the ophthalmic pathology laboratory of the eye bank of iran between 2004 and 2007 underwent histopathologic examination. results: overall, 315 corneal specimens were evaluated. histopa...
objective: nanosilver has numerous applications in medicine due to its potent antibacterial activity. however, data regarding the bio-safety of its effective concentrations is scarce. this study aims to assess the toxicity of silver nanoparticles on human gingival epithelial cells under in-vitro conditions. methods: this in vitro study evaluated the toxic effects of filtered and unfiltered na...
Occludin is an integral membrane protein localizing at tight junctions in epithelial and endothelial cells. Occludin from confluent culture MDCK I cells resolved as several (>10) bands between 62 and 82 kD in SDS-PAGE, of which two or three bands of the lowest Mr were predominant. Among these bands, the lower predominant bands were essentially extracted with 1% NP-40, whereas the other higher M...
Cyclooxygenase-2 (COX-2) is overexpressed in a variety of human epithelial cancers, including lung cancer, and is highly associated with a poor prognosis and a low survival rate. Understanding how COX-2 is regulated in response to carcinogens will offer insight into designing anti-cancer strategies and preventing cancer development. Here, we analyzed COX-2 expression in several human lung cance...
The p27 cyclin-dependent kinase inhibitor is a negative regulator of cell-cycle progression. In many human epithelial malignancies, decreased expression of p27 correlates with high grade, early recurrence, and poor prognosis. To evaluate the prognostic significance of p27 in hepatocellular carcinoma (HCC), we studied 54 HCCs along with corresponding nontumoral tissue. Immunohistochemistry (IHC)...
BACKGROUND The addition of MRI to mammography and ultrasound for breast cancer screening has been shown to improve screening sensitivity for high risk women, but there is little data to date for women at average or intermediate risk. METHODS Two thousand nine hundred and ninety-five women, aged 40 to 65 years with no previous history of breast cancer were enrolled in a screening program, whic...
