The 28-kDa (on SDS-PAGE) Ca2+-regulated heat stable protein (CRHSP28) was recently purified as novel phosphoprotein in exocrine pancreas, since it undergoes an immediate increase in serine phosphorylation when acini are stimulated with Ca2+-mobilizing agonists. Examination of CRHSP28 protein expression in rat revealed that most was highly expressed in pancreas and other morphologically related ...

Several lines of investigation point to a new herpesvirus, human herpesvirus-8 (HHV-8), as the cause of two different neoplasms seen in AIDS patients-Kaposi's sarcoma (KS) and body cavity B cell lymphoma. If this virus is the etiological agent, rather than another opportunistic infectious agent, it should be present in the earliest detectable clinical lesions on a temporal basis, and localize t...

PURPOSE Although over-expression of hepatocyte growth factor (HGF) and neuregulin-1 (NRG1) are important mechanisms involved in acquired drug-resistance in many cancers, few reports have evaluated their clinicopathologic features and prognostic significance. The aim of our study was to investigate protein expressions of HGF and NRG1 in lung adenocarcinomas and their association with clinicopath...

Artemether exhibits diverse pharmacological effects and has multiple applications. This study aimed to investigate its antiproliferative and apoptogenic effects on HaCaT cells and keratinocyte differentiation-inducing activity in vivo. WST-8 analysis demonstrated that Artemether can inhibit the proliferation of cultured HaCaT cells in a time- and dose-dependent manner. Annexin V/PI dual stainin...

Central nervous system consists of a myriad of cell types. In particular, many subtypes of neuronal cells, which are interconnected with each other, form the basis of functional circuits. With the advent of genomic era, there have been systematic efforts to map gene expression profiles by in situ hybridization (ISH) and enhancer-trapping strategy. To make full use of such information, it is imp...

We describe a simple and rapid protocol for the flow cytometric analysis of the cell cycle in transfected cells using a green fluorescent protein anchored in the intracellular membranes of the endoplasmic reticulum (ER-GFP) as a transfection marker. The transfected cells are analyzed by dual-parameter flow cytometry after a brief incubation with digitonin, followed by staining with propidium io...

The age-related pathological cascade underlying intraneuronal tau formation in 3xTg-AD mice, which harbor the human APP(Swe), PS1(M126V) , and Tau(P301L) gene mutations, remains unclear. At 3 weeks of age, AT180, Alz50, MC1, AT8, and PHF-1 intraneuronal immunoreactivity appeared in the amygdala and hippocampus and at later ages in the cortex of 3xTg-AD mice. AT8 and PHF-1 staining was fixation ...

BACKGROUND Lymphovascular space invasion (LVSI) is an important step in the complex process of tumour metastasis. Various methods have been used in the past to improve the histological detection of LVSI. AIMS To develop a sensitive immunohistochemical method for the detection of LVSI. METHODS Paraffin wax blocks from 108 patients who had undergone hysterectomy for stage I endometrial cancer...

Antibodies are widely available and cost-effective research tools in life science, and antibody conjugates are now extensively used for targeted therapy, immunohistochemical staining, or in vivo diagnostic imaging of cancer. Significant advances in site-specific antibody labeling technologies have enabled the production of highly characterized and homogenous conjugates for biomedical purposes, ...

The mammalian target of rapamycin (mTOR) pathway may constitute a potential target for the treatment of malignant peripheral nerve sheath tumors (MPNST). However, investigations of other cancers suggest that mTOR blockade can paradoxically induce activation of prosurvival, protumorigenic signaling molecules, especially upstream AKT. Consequently, we hypothesized that dual phosphatidylinositol 3...
