Effects of 17α‐Ethinylestradiol on Development and Gonadal Differentiation in the Estuarine Mummichog, Fundulus heteroclitus

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heteroclitus) to investigate gonadal differentiation following exposure to the synthetic estrogen, 17α‐ethinylestradiol (EE2).

Molecular Investigations on Angiogenesis and Oxidative Stress in Roe Deer (Capreolus capreolus) Bucks' Testes Throughout the Reproductive Cycle

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Animals with seasonal reproductive cycles, as the Roe deer (Capreolus capreolus), have developed mechanisms to synchronize reproduction with the environmental cycle in order to optimize reproductive success through melatonin. Angiogenesis and oxidative stress are key processes in spermatogenesis, contributing to testicular remodeling and ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...
