We have used antibodies directed against a number of nuclear pore complex (NPC) proteins to determine their mutual interactions and location within the three-dimensional structure of the NPC. A monoclonal antibody, termed QE5, recognized three NPC polypeptides, p250, NUP153, and p62 on Western blots, and labeled the nuclear envelope of several cultured cell lines by immunofluorescence microscop...

despite the major advances in conventional forms of treatment (i.e. surgical techniques, radiotherapy and chemotherapy) and improved survival rates, cancer is still the second leading cause of death in developing countries. one major limitation of cytotoxic drugs and radiation in the treatment of cancer patients is their inability to discriminate between malignant and normal tissues. this in tu...

Introduction. Paraneoplastic encephalomyelitis (PEM) and subacute sensory neuronopathy (SSN) are remote effects of cancer, usually associated with small-cell lung carcinoma and positive anti-Hu antibody. We describe the rare association of bladder transitional cell carcinoma (TCC) with anti-Hu antibody positivity resulting in this paraneoplastic neurological syndrome. Patient. A 76-year-old fem...

Fifty years have passed since anti-mitochondrial antibodies were found in patients with primary biliary cirrhosis (PBC). PBC is an autoimmune hepatic disease in which 85-90% of patient antibodies bind to mitochondrial antigens that include pyruvate dehydrogenase complex (PDC)-E2 and other members of the oxaloacid dehydrogenase family. In addition, indirect immunofluorescence (IIF) assays utiliz...

background: preeclampsia (pe) is a pregnancy specific syndrome that is associated with high maternal and fetal morbidity and mortality. glucose regulated protein78 (grp78) is an endoplasmic reticulum (er) protein which is expressed on the cell surfaces of trophoblast cells under stress or hypoxic condition. grp78 has a role in aggressive behavior of invasive cells and may play a role in normal ...

An external pinkish growing mass that emerged from the right nostril of an adult goldfish Carassius auratus L. was evaluated by means of light microscopy and immunohistochemistry. The neoplasm presented a well-developed fibrovascular stroma associated with solid cell nests and a large number of Flexner-Wintersteiner rosettes. Myelinated fibres were observed around them. Neoplastic cells showed ...

Background: Streptokinase, which is injected intravenously with a standard dose of 1.5 MIU, is the most widely used thrombolytic agent around the world. What is so important about this bioproduct is the level of antistreptokinase (anti-sk) antibody in the population, which is directly correlated to the incidence of streptococcal infections in that population. Objective: Since Iran is an endemic...
