The nucleotide sequence of a cloned Muntjak satellite IA repeat unit (Muntiacus muntjak vaginalis) was determined. The repeat is 807 base pairs (bp) long. By introducing minor deletions and insertions, the whole sequence of the satellite can be arranged in 27 subrepeats of 31 bp length. Although diverged relative to each other, all subrepeats show a(More)
In recent work we have isolated and characterized a highly repetitive DNA (MMV satellite IA) from Muntiacus muntjak vaginalis, the species with the most reduced karyotype in the Cervidae family. We have now analysed the genomes of nine related species for the presence of MMV satellite IA components, and have determined their organization and chromosomal(More)
A highly repeated DNA (designated satellite IA) was isolated from cultured cells of Muntiacus muntjak vaginalis and its organization analyzed by the use of restriction nucleases and hybridization experiments with cloned DNA-fragments. Several restriction nucleases cleave the satellite IA DNA into a series of fragments, which are multiples of a basic repeat(More)
The question of nucleosome phasing on African Green Monkey (AGM) alpha-satellite DNA has been addressed by employing a new approach. Nucleosome cores were prepared from AGM nuclei with micrococcal nuclease, exonuclease III and nuclease S1. The core DNA population derived from alpha-satellite DNA containing chromatin was purified from total core DNA by(More)

By the use of restriction endonucleases the organization of the alpha-satellite DNA from African green monkey cells (Cercopithecus aethiops) has been analyzed. With endo R-HindIII, endo R-AluI and with endo R-EcoRI at conditions of low salt and high pH (endo R-EcoRI) all of the satellite was digested while only a part of the satellite was cleaved with endo(More)
Experiments have been designed to investigate hormonal effects on the human prostatic carcinoma cell line LNCaP in the presence of complete foetal calf serum. At physiological concentrations (3.3 x 10(-9)M), several derivatives of 17 alpha-methyl-testosterone led to a significant reduction of cell proliferation, inhibition of colony formation in soft agar,(More)
A cDNA clone of human Prostate Specific Antigen (PSA) was isolated from a cDNA library in the expression vector lambda gt11. The library was constructed starting from poly-A containing RNA of androgen-induced (1) LNCaP cells (2). The sequence obtained (3) was aligned with the published amino acid sequence of the mature PSA protein (4) and a genomic clone(More)
We have investigated the modulation of prostatic acid phosphatase expression in the human prostatic cancer cell line LNCaP in response to the natural androgens testosterone and dihydrotestosterone, the female sex steroid estradiol and the synthetic androgen R1881 (methyltrienolone). Testosterone and dihydrotestosterone at 1 microgram/ml enhance the acid(More)
Using gene-specific synthetic oligonucleotides the expression and regulation of kallikrein-like genes in the human prostatic cancer cell line LNCaP were studied. Prostate-specific antigen (PSA) and human glandular kallikrein (hGK-1) together constitute a subfamily of serine proteases exclusively produced in the human prostate. RNA analysis revealed that(More)
