Summary It has been shown previously that the intact adult rat testis produces large amounts of an interleukin-1 (IL-1)-like growth factor. The present study has investigated whether this testicular IL-1-like factor (tIL-1) is produced and secreted d

As a first step toward understanding estrogen's role in neurodevelopment, a PCR cloning strategy was used to isolate complementary DNAs encoding two distinct cytochrome P450 aromatase isoforms in adult zebrafish (Danio rerio) brain and ovary (termed

Cadmium (Cd) is an established spermatotoxicant. Using the shark (Squalus acanthias) testis model, we investigated stage-related patterns of intratesticular Cd accumulation and effect. After a single injection of 109CdCl2, tracer was rapidly eliminat

To investigate the molecular basis and physiological regulation of exceptionally high levels of aromatase (P450arom) activity in the brain of teleost fish, a 2927 bp P450arom cDNA encoding a 510 amino acid protein was isolated from a goldfish brain c

To investigate factors controlling spermatogonial proliferation, we used premeiotic (PrM) spermatocysts (stage-synchronized germ cell/Sertoli cell clones) derived from the testis of the dogfish shark (Squalus acanthias) as an in vitro test system to

While intrasexual competition for mates is generally considered to be an androgen-dependent characteristic of reproductively active males, in the Wilson's phalarope (Phalaropus tricolor) it is the female that acquires the brighter nuptial plumage and

The testicular estrogen receptor of the shark Squalus acanthias is restricted to nuclear subfractions when tissue is homogenized in low salt buffers and adheres tightly to nuclei and DNA-cellulose even when exposed to high salt conditions. Therefore,

The subcellular distribution patterns of aromatase, 5 alpha- and 5 beta-reductase in the hypothalamus/preoptic area of Japanese quail were studied using standard methods of centrifugation, and fractional constituents were identified by marker enzymes
