Preoptic GnRH and AVT: axes for sexual plasticity in teleost fish

General and Comparative Endocrinology
C M Foran, A H Bass

Abstract

Alternative reproductive tactics within one sex, adult sex or role change, and reproductive suppression are all forms of reproductive plasticity commonly exhibited among teleost fishes. The two neuropeptides that have been most extensively studied with regard to such behavioral plasticity are gonadotropin releasing hormone (GnRH) and arginine vasotocin (AVT). Here, we review intra- and intersexual variation in the number and size of GnRH and AVT neurons along with gonadal phenotype in those species of teleosts showing intraspecific plasticity in reproductive behavior. In several species, male dimorphisms in the number and/or size of GnRH neurons in the forebrain's preoptic area parallel a divergence in relative gonad size and reproductive tactics. The available studies of AVT-containing neurons in the preoptic area also indicate intrasexual dimorphisms among males, although a proximate link to other reproductive traits and behavioral outcomes is more difficult to recognize. For both GnRH and AVT, there are also species-typical patterns in the coupling between structural (e.g., neuronal and gonadal) traits and reproductive tactic expressed, which likely reflect distinct patterns of adaptation to particular ecological environment...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
