Nucleoporin107 mediates female sexual differentiation via Dsx

open access: yeseLife, 2022
We recently identified a missense mutation in Nucleoporin107 (Nup107; D447N) underlying XX-ovarian-dysgenesis, a rare disorder characterized by underdeveloped and dysfunctional ovaries.

Effects of the Thyroid Endocrine System on Gonadal Sex Ratios and Sex-Related Gene Expression in the Pufferfish Takifugu rubripes

open access: yesFrontiers in Endocrinology, 2021
To examine the effect and mechanism of thyroid hormone on gonadal sex differentiation, Takifugu rubripes larvae were treated with goitrogen (methimazole, MET, 1000 μg/g), and thyroxine (T4, 2nM) from 25 to 80 days after hatching (dah).

Putative Role of CFSH in the Eyestalk-AG-Testicular Endocrine Axis of the Swimming Crab Portunus trituberculatus

open access: yesAnimals, 2023
It has been shown in recent studies that the crustacean female sex hormone (CFSH) plays a crucial role in the development of secondary sexual characteristics in Decapoda crustaceans. However, research on the function of CFSH in the eyestalk-AG-testicular

ATRX and sex differentiation

open access: yesTrends in Endocrinology & Metabolism, 2004
Most interest in the gene encoding the alpha-thalassemia, mental retardation, X-linked protein (ATRX) has traditionally been focused on its role in brain development and globin regulation. However, mutations in the ATRX gene also cause varying degrees of gonadal and urogenital abnormalities. These range from small testes to ambiguous external genitalia

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

open access: yes, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.
