Capacidade reprodutiva de Bothrops jararaca (Serpentes, Viperidae) Reproductive capacity of Bothrops jararaca (Serpentes, Viperidae)

open access: yesIheringia: Série Zoologia, 2004
The relationship between female body size and egg number was examined in the snake Bothrops jararaca (Wied, 1924). Some authors have demonstrated that the estimated clutch size may be affected by the inclusion or exclusion of dead neonates or non ...

Investigation of Ovum Transport in the Oviduct: The Dynamics of Oviductal Fluids in Domestic Rabbits [PDF]

open access: yesJournal of International Medical Research, 1999
Ova are captured by the oviductal fimbria and rapidly transported to the ampullary-isthmic junction of the fallopian tube. Fertilized ova and oviductal fluids are then carried medially in the fallopian tube, while undergoing maturation in preparation for entering the uterine cavity, where nidation and further development take place.

The Nuclear Localization of ACLY Guards Early Embryo Development Through Recruiting P300 and HAT1 to Promote Histone Acetylation and Transcription

open access: yesAdvanced Science, EarlyView.
ACLY is vital for early embryo development. IGF‐1 activates AKT to phosphorylate ACLY, driving its nuclear localization and recruitment of HATs (P300/HAT1), boosting acetyl‐CoA production and histone acetylation for transcriptional activation. Conversely, ACLY deficiency (via knockdown, knockout, or AKT inhibition) reduces nuclear acetyl‐CoA, disrupts ...

Sperm migration in the genital tract-In silico experiments identify key factors for reproductive success.

open access: yesPLoS Computational Biology, 2021
Sperm migration in the female genital tract controls sperm selection and, therefore, reproductive success as male gametes are conditioned for fertilization while their number is dramatically reduced.

Inflammation is a key contributor to ovarian cancer cell seeding. [PDF]

open access: yes, 2018
The incidence of ovarian cancer dramatically increases in early menopause but the factors contributing to cancer onset are unclear. Most ovarian cancers originate in the fallopian tube with subsequent implantation of malignant cells into the ovary ...

Post‐Translational Modifications in Cilia and Ciliopathies

open access: yesAdvanced Science, EarlyView.
This review synthesizes current understanding of post‐translational modifications (PTMs) in ciliary proteins and emphasizes their roles in ciliary formation, homeostasis, and signaling. This review also discusses the implication of PTM dysregulation in ciliopathies and explores therapeutic strategies targeting PTM‐modifying enzymes.

Oviductal estrogen receptor α signaling prevents protease-mediated embryo death

open access: yeseLife, 2015
Development of uterine endometrial receptivity for implantation is orchestrated by cyclic steroid hormone-mediated signals. It is unknown if these signals are necessary for oviduct function in supporting fertilization and preimplantation development ...
