Implementation of meiosis prophase I programme requires a conserved retinoid-independent stabilizer of meiotic transcripts

Nature Communications, 2016
Meiosis is a cell division program that produces haploid gametes and is initiated by a retinoic acid-dependent process. Here the authors report that a meiosis-specific protein, MEIOC, is upregulated in a retinoic acid-independent manner and is required ...

Inhibin immunoreactivity in gonadal and non-gonadal tumors [PDF]

The Journal of Steroid Biochemistry and Molecular Biology, 1990
Inhibin immunoreactivity was estimated in a number of gonadal and non-gonadal tumors. Dog Sertoli cell tumors and human granulosa cell and Leydig cell tumors contained high concentrations of inhibin-like material. Levels, comparable with those in normal testes and ovaries were detected in human testicular non-seminomas and in ovarian cystadenomas ...
