\u3cem\u3eDrosophila\u3c/em\u3e Vitelline Membrane Assembly: A Critical Role for an Evolutionarily Conserved Cysteine in the “VM domain” of sV23 [PDF]

open access: yes, 2010
The vitelline membrane (VM), the oocyte proximal layer of the Drosophila eggshell, contains four major proteins (VMPs) that possess a highly conserved “VM domain” which includes three precisely spaced, evolutionarily conserved, cysteines (CX7CX8C ...

The Functions of the Multiproduct and Rapidly Evolving \u3cem\u3edec-1\u3c/em\u3e Eggshell Gene Are Conserved Between Evolutionarily Distant Species of Drosophila [PDF]

open access: yes, 2001
The Drosophila dec-1 gene encodes multiple proteins that are required for female fertility and proper eggshell morphogenesis. Genetic and immunolocalization data suggest that the different DEC-1 proteins are functionally distinct.

Modulation by cAMP of a Slowly Activating Potassium Channel Expressed in \u3cem\u3eXenopus\u3c/em\u3e Oocytes [PDF]

open access: yes, 1992
When expressed in the Xenopus oocyte, the minK protein induces a slowly activating voltage-dependent potassium current (Isk). We studied the modulation of this current by altering intracellular cAMP levels and found that the amplitude of Isk is ...

Molecular genetics of oogenesis in Drosophila melanogaster

open access: yesInvertebrate Survival Journal, 2004
Gonadal development requires complex differentiation programs leading to the production of functional female and male gametes. Upon fertilization, while the male germ cell contributes to the newly formed zygote only its genetic material, the female germ ...

When Regenerative Medicine Faces the Challenges of Reproductive Medicine: A Review Study on Recent Advances in the Strategies for Derivation of Gametes from Stem Cells

open access: yesEuropean Medical Journal Reproductive Health, 2020
The murine model has allowed for the replication of all developmental stages of the mammalian germline in vitro, from embryonic stem cells to epiblast cells, primordial germ cells, and finally into functional haploid gametes.
