Characterization and distribution of kisspeptins, kisspeptin receptors, GnIH, and GnRH1 in the brain of the protogynous bluehead wrasse (Thalassoma bifasciatum)

JOURNAL OF CHEMICAL NEUROANATOMY, 121.

By: M. Lamm n, A. Lamb n, B. Klapheke n, W. Tyler* & J. Godwin n

author keywords: Kisspeptin; GnRH; GnIH; Teleost; Reproduction; Sex change
MeSH headings : Animals; Brain / metabolism; Female; Gonadotropin-Releasing Hormone / metabolism; Gonadotropins / metabolism; Kisspeptins / genetics; Kisspeptins / metabolism; Male; Perciformes / metabolism
TL;DR: This study characterized expression of kisspeptin-system genes (kiss1, kiss2, kissr1, and kissr2), gnih, and gnrh1 in the brain of the bluehead wrasse, an important teleost model of socially-controlled sex change and suggested that if kisspeptins do signal GnRH1 neurons, the interaction is indirect, possibly through neurons adjacent to Gn RH1.

Estrogenic signaling and sociosexual behavior in wild sex-changing bluehead wrasses, Thalassoma bifasciatum

Prim, J. H., Phillips, M. C., Lamm, M. S., Brady, J., Cabral, I., Durden, S., … Godwin, J. (2021, November 9). JOURNAL OF EXPERIMENTAL ZOOLOGY PART A-ECOLOGICAL AND INTEGRATIVE PHYSIOLOGY, Vol. 11.

By: J. Prim n, M. Phillips n, M. Lamm n, J. Brady*, I. Cabral*, S. Durden*, E. Dustin n, A. Hazellief* ...

author keywords: aromatase; estrogen; estrogen receptor; sex change; sociosexual behavior
MeSH headings : Animals; Female; Fishes; Gonads; Male; Perciformes; Sex Determination Processes; Sex Differentiation
TL;DR: Variation in estrogenic signaling across three sexual phenotypes is examined, suggesting alterations in neural estrogen signaling are key regulators of socially-controlled sex change and sexual phenotype differences and the possibility that an inverted-U shaped relationship between neural estrogen and male-typical behaviors is more common than presently appreciated.

Conservation and diversity in expression of candidate genes regulating socially-induced female-male sex change in wrasses

PEERJ, 7.

author keywords: Protogynous sex change; Bluehead wrasse; Spotty wrasse; Kyusen wrasse; Quantitative real-time PCR; Sex-biased gene expression; cyp19a1a; cyp19a1b; amh; Isotocin
TL;DR: While key components of the molecular machinery controlling gonadal sex change are phylogenetically conserved among wrasses, neural pathways governing behavioural sex change may be more variable. (via Semantic Scholar)

TL;DR: These findings reveal at a molecular level how a normally committed developmental process remains plastic and is reversed to completely alter organ structures. (via Semantic Scholar)

Female Mimicry by Sneaker Males Has a Transcriptomic Signature in Both the Brain and the Gonad in a Sex-Changing Fish

Molecular Biology and Evolution, 35(1), 225–241.

author keywords: developmental plasticity; alternative male reproductive strategies; transcriptomics; phenotypic plasticity
MeSH headings : Adaptation, Physiological / genetics; Animals; Biological Mimicry / genetics; Brain / metabolism; Female; Gene Expression Profiling / methods; Gene Expression Regulation / genetics; Gonads / metabolism; Male; Oxytocin / analogs & derivatives; Perciformes / genetics; Phenotype; Reproduction / physiology; Sex Characteristics; Sexual Behavior, Animal / physiology; Transcriptome / genetics
TL;DR: It is proposed that morphological female-mimicry by sneaker male teleosts entails pervasive downregulation of androgenesis genes, consistent with low androgen production in males lacking well-developed secondary sexual characters. (via Semantic Scholar)

Variation in gene transcript profiles of two V1a-type arginine vasotocin receptors among sexual phases of bluehead wrasse (Thalassoma bifasciatum)

GENERAL AND COMPARATIVE ENDOCRINOLOGY, 179(3), 451–464.
