Literature on steroid hormone receptors is reviewed. Cytosol and nuc lear estrogen receptors in the mammalian uterus, the mechanism of entry of estradiol into uterine cells, the regulation of the amount of uterine estrogen receptors, estrogen receptors in other organs and species, the chick oviduct system and progesterone receptors in the mammalian uterus,(More)
Complementary DNA clones, encoding the LH-hCG (luteinizing hormone-human choriogonadotropic hormone) receptor were isolated by screening a lambda gt11 library with monoclonal antibodies. The primary structure of the protein was deduced from the DNA sequence analysis; the protein contains 696 amino acids with a putative signal peptide of 27 amino acids.(More)
Deletion mutants of the rabbit progesterone receptor were used to identify two major mechanisms of its nuclear localization. A putative signal sequence, homologous to that of the SV40 large T antigen, was localized around amino acids 638-642 and shown to be constitutively active. When amino acids 638-642 were deleted, the receptor became cytoplasmic but(More)
A lambda gt10 library containing DNAs complementary to messenger RNAs from human breast cancer T47-D cells was constructed and screened with a cDNA probe encoding the rabbit progesterone receptor. Four overlapping clones have been sequenced. The open reading frame corresponds to a protein of 933 amino acids with a molecular weight of 98,868 Da. The cysteine(More)
Differential hybridization of cDNAs corresponding to mRNAs expressed in the human endometrium during the secretory phase or during the first trimester of pregnancy, but not during the proliferative phase, allowed us to isolate and characterize cDNAs encoding human placental protein 14 (PP14). The cDNA was used to isolate the PP14 gene from a human genomic(More)
Messenger RNAs (mRNAs) were prepared from MCF-7 breast cancer cells grown in the presence of estradiol. Complementary DNAs (cDNAs) were inserted into pBR322 plasmid and a library of 4400 recombinant bacterial clones was prepared. The clones were screened by in situ differential hybridization with cDNAs prepared from RNAs of MCF-7 cells grown either in the(More)
Complementary cDNA clones encoding the TSH (thyroid stimulatory hormone) receptor were isolated from a human thyroid lambda gt10 library using Iow stringency hybridization with LH/hCG (luteinizing hormone-human choriogonadotropic hormone) receptor probes. Sequencing of the clones showed a 764 amino acid open reading frame. The first 21 amino acids probably(More)
Two lambda gt11 clones containing fragments of cDNA encoding the rabbit progesterone receptor were isolated with the aid of monoclonal and monospecific polyclonal antireceptor antibodies. RNA gel blot analysis showed that the corresponding mRNA was approximately equal to 5900 nucleotides in size and present in the uterus, where its concentration was(More)
