Cloning and characterization of androgen-dependent mRNA from rat ventral prostate. 1980

M G Parker, and R White, and J G Williams

DNA complementary to three androgen-dependent mRNAs from rat ventral prostate has been cloned in the bacterial plasmid pAT 153. DNA sequences coding for 20,000, 10,000, and 9,000 translation products, the precursors of polypeptides secreted in vivo (Parker, M. G., and Scrace, G.T. (1979) Proc. Natl. Acad. Sci. U.S.A. 76, 1580--1584) were identified in recombinant plasmids. The levels of mRNA coding for the 20,000 and 10,000 translation products were quantitated using cDNA probes and also by hybridization in situ with RNA that had been covalently bound to diazobenzyloxymethyl paper. Both mRNAs responded with similar kinetics to androgen withdrawal and testosterone stimulation. The sequences declined with nonlinear kinetics by at least 3 orders of magnitude after androgen withdrawal and are induced by testosterone without an appreciable lag, a 3-fold increase being detectable within 2 h. Analysis of the RNA bound to diazobenzyloxymethyl paper indicates that the mRNAs coding for the 20,000, 10,000, and 9,000 translation products contain 930, 640, and 550 nucleotides, respectively.

D009693	Nucleic Acid Hybridization	Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant
D010957	Plasmids	Extrachromosomal, usually CIRCULAR DNA molecules that are self-replicating and transferable from one organism to another. They are found in a variety of bacterial, archaeal, fungal, algal, and plant species. They are used in GENETIC ENGINEERING as CLONING VECTORS.	Episomes,Episome,Plasmid
D011467	Prostate	A gland in males that surrounds the neck of the URINARY BLADDER and the URETHRA. It secretes a substance that liquefies coagulated semen. It is situated in the pelvic cavity behind the lower part of the PUBIC SYMPHYSIS, above the deep layer of the triangular ligament, and rests upon the RECTUM.	Prostates
D002369	Castration	Surgical removal or artificial destruction of gonads.	Gonadectomy,Castrations,Gonadectomies
D003001	Cloning, Molecular	The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.	Molecular Cloning
D003534	Cyproterone	An anti-androgen that, in the form of its acetate (CYPROTERONE ACETATE), also has progestational properties. It is used in the treatment of hypersexuality in males, as a palliative in prostatic carcinoma, and, in combination with estrogen, for the therapy of severe acne and hirsutism in females.

D004274	DNA, Recombinant	Biologically active DNA which has been formed by the in vitro joining of segments of DNA from different sources. It includes the recombination joint or edge of a heteroduplex region where two recombining DNA molecules are connected.
