A homolog of the fission yeast cdc2-encoded protein kinase (p34) is a component of M phase promoting factor in Xenopus oocytes. The homologous kinase in human HeLa cells is maximally active during mitosis, suggesting a mitotic role in mammalian somatic cells. This has been directly investigated by microinjection of anti-p34 antibodies into serum-stimulated(More)
Alzheimer's Disease (AD) is characterized by the appearance of neurofibrillary and granulovacuolar lesions in the brains of affected individuals. The former is composed of hyperphosphorylated aggregates of the microtubule-associated protein tau. The latter is poorly characterized but reacts strongly with anti-phosphoepitope antibodies indicating that it too(More)
Paired helical filaments (PHFs) are the major components of neurofibrillary lesions present in Alzheimer's disease (AD). PHFs are composed of the microtubule-associated protein (MAP) tau, which is abnormally phosphorylated in AD. Normal fetal tau is also phosphorylated and shares certain phosphoepitopes with PHF-tau. The abnormal phosphorylation of PHF-tau(More)
An estradiol metabolite, 2-methoxyestradiol (2-MeOE(2)), has shown antiproliferative effects in both hormone-dependent and hormone-independent breast cancer cells. Previously, a series of 2-hydroxyalkyl estradiol analogs had been synthesized in our laboratories as potential probes for comparison of estrogen receptor (ER)-mediated versus non-ER-mediated(More)
The syncytiotrophoblast of the human placenta is an epithelial barrier that interacts with maternal blood and is a key for the transfer of nutrients and other solutes to the developing fetus. The syncytiotrophoblast is a true syncytium and fusion of progenitor cytotrophoblasts is the cardinal event leading to the formation of this layer. BeWo cells are(More)
A proteomics survey of human placental syncytiotrophoblast (ST) apical plasma membranes revealed peptides corresponding to flotillin-1 (FLOT1) and flotillin-2 (FLOT2). The flotillins belong to a class of lipid microdomain-associated integral membrane proteins that have been implicated in clathrin- and caveolar-independent endocytosis. In the present study,(More)
