TLDR
In this article, the effects of progestin, androgens, and estrogens on global testicular gene expression patterns (microarray analysis), and molecular mechanisms by which steroids regulate specific candidate genes (identified by subtractive hybridization approaches) during early stages of testis maturation are discussed.About:

TL;DR: Puberty comprises the transition from an immature juvenile to a mature adult state of the reproductive system, i.e. the individual becomes capable of reproducing sexually for the first time, which implies functional competence of the brain-pituitary-gonad (BPG) axis.

Endocrine disruption potentials of organophosphate flame retardants and related mechanisms in H295R and MVLN cell lines and in zebrafish
TL;DR: The results of this study showed that OPFRs could alter sex hormone balance through several mechanisms including alterations of steroidogenesis or estrogen metabolism.

The Sertoli cell: one hundred fifty years of beauty and plasticity.
Luiz R. França,Luiz R. França,Rex A. Hess,Jannette M. Dufour,Marie Claude Hofmann,Michael D. Griswold +5 more
TL;DR: This review examines the three phases of morphological research that have occurred in the study of Sertoli cells, because microscopic anatomy was essentially the only scientific discipline available for about the first 75 years after the discovery of the testicular ‘nurse cell’.
Journal ArticleDOI
Normal Anatomy and Histology of the Adult Zebrafish
TL;DR: The zebrafish has been shown to be an excellent vertebrate model for studying the roles of specific genes and signaling pathways and the location and histology of the major zebra fish organ systems are described with a brief description of their function.

A New and Fast Technique to Generate Offspring after Germ Cells Transplantation in Adult Fish: The Nile Tilapia (Oreochromis niloticus) Model

TL;DR: It is shown that injecting germ cells directly into adult testis facilitates and enable fast generation of donor spermatogenesis and offspring compared to previously described methods, which indicates that a new suitable methodology for biotechnological investigations in aquaculture was established.

TL;DR: The genome of the yeast Saccharomyces cerevisiae has been completely sequenced through a worldwide collaboration and provides information about the higher order organization of yeast's 16 chromosomes and allows some insight into their evolutionary history.

TL;DR: Puberty is initiated when gonadotropin-releasing hormone begins to be secreted by the hypothalamus, and complementary genetic approaches in humans and mice identified genetic factors that determine the onset of puberty.

TL;DR: The observations suggest a conserved function for Piwi-clade proteins in the control of transposons in the germline, and this work examines the effects of disrupting the gene encoding the third family member, MIWI2.
