We have cloned and sequenced the complete complementary DNA of the oestrogen receptor (ER) present in the breast cancer cell line MCF-7. The expression of the ER cDNA in HeLa cells produces a protein that has the same relative molecular mass and binds oestradiol with the same affinity as the MCF-7 ER. There is extensive homology between the ER and the erb-A(More)
Familial hemophagocytic lymphohistiocytosis (FHL) is a rare, rapidly fatal, autosomal recessive immune disorder characterized by uncontrolled activation of T cells and macrophages and overproduction of inflammatory cytokines. Linkage analyses indicate that FHL is genetically heterogeneous and linked to 9q21.3-22, 10q21-22, or another as yet undefined locus.(More)
Two domains of the human estrogen receptor, responsible for hormone binding (region E) and tight nuclear binding (region C), are essential for the receptor to activate efficiently the transcription of estrogen-responsive genes. Region D, which joins the DNA- and hormone-binding domains, can be altered without affecting activation. Deletion of the N-terminal(More)
A chicken oviduct cDNA clone containing the complete open reading frame of the oestrogen receptor (ER) has been isolated and sequenced. The mol. wt of the predicted 589-amino acid protein is approximately 66 kd which is very close to that of the human ER. Comparison of the human and chicken amino acid sequences shows that 80% of their amino acids are(More)
Extracts containing wild-type or mutant human estrogen receptor (ER) have been used to study the binding of ER to its responsive element (ERE). Estradiol (E2) or the antiestrogen hydroxytamoxifen is required for ER binding as assayed by gel retardation. The DNA binding domain (DBD) encompasses the highly conserved region C. Both intact ER-E2 complexes and(More)
2B4 is a member of the CD2 subset of the immunoglobulin superfamily molecules expressed on natural killer (NK) cells and other leukocytes. It is the high affinity ligand for CD48. Engagement of 2B4 on NK-cell surfaces with specific antibodies or CD48 can trigger cell-mediated cytotoxicity, interferon-gamma secretion, phosphoinositol turnover and NK-cell(More)
The immunological markers proposed to supplement intestinal biopsy for the diagnosis of coeliac disease are antigliadin, antireticulin and antiendomysial antibodies. These antibodies have been studied separately or compared as pairs, but no prospective comparison of all three antibodies in childhood coeliac disease exists. Thirty-four confirmed coeliacs(More)
AIMS Fluorescent pseudomonads are widely used as bioinoculants for improving plant growth and controlling phytopathogenic fungi. Piriformospora indica (Pi), a symbiotic root endophyte, also has beneficial effects on a number of plants. The present study focuses on the improvement of growth yields of tomato plants and control of Fusarium wilt using inorganic(More)
The release of cytochrome c from mitochondria results in the formation of an Apaf-1-caspase-9 apoptosome and induces the apoptotic protease cascade by activation of procaspase-3. The present studies demonstrate that heat shock protein 90 (Hsp90) forms a cytosolic complex with Apaf-1 and thereby inhibits the formation of the active complex. Immunodepletion(More)
