Androgen dependence during development of the mouse vas deferens protein mRNA. 1991

The mRNA encoding a major protein of the mouse vas deferens (MVDP) was first detected in 10-day-old males and its concentration increased sharply between 10 and 20 days, reaching adult levels at 40 days. This increase was not associated with an increase in tissular androgen concentrations. In 30-day-old mice castrated at birth or treated with cyproterone acetate over 29 days, MVDP mRNA levels were not abolished and were similar to those measured in 10- and 20-day-old controls. These results suggest that the neonatal expression of MVDP gene is independent of androgens. In addition, precocious accumulation of MVDP mRNA could be induced by injection of excess amounts of androgens in 20- but not in 10-day-old animals. The prepubertal increase in MVDP mRNA levels is androgen-dependent but other factors may be necessary for MVDP expression.

UI	MeSH Term	Description	Entries
D008297	Male		Males
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.

D011506	Proteins	Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.

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.

D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

D000728	Androgens	Compounds that interact with ANDROGEN RECEPTORS in target tissues to bring about the effects similar to those of TESTOSTERONE. Depending on the target tissues, androgenic effects can be on SEX DIFFERENTIATION; male reproductive organs, SPERMATOGENESIS; secondary male SEX CHARACTERISTICS; LIBIDO; development of muscle mass, strength, and power.
