Communication in Biomathematical Sciences, 2019 The coat color of cats is normally governed by genes found on the X chromosome in both male chromosome XY and female chromosome XX. The meiosis failure in the process of gametogenesis leads to the birth of three-colored male cats caused by an excess of ...

Germinal Epithelium Cytology during Spermatogenesis in the Alligator Snapping Turtle, Macrochelys temminckii (Reptilia: Chelydridae) [PDF]
, 2018 We investigated the cytology of the seminiferous epithelia of the Alligator Snapping Turtle (Macrochelys temminckii). Spermatogenic and regressed testes were assessed from 2 adult individuals collected in Arkansas in May and September of 1993 ...

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

ATR is required to complete meiotic recombination in mice
Nature Communications, 2018 ATR kinase is required for meiosis in non-mammalian model organisms. Here the authors demonstrate, using a hypomorphic Atr mutation and chemical inhibition, that ATR is also essential for male meiosis in mouse, regulating meiotic recombination and ...

A CRISPR-Cas9 sex-ratio distortion system for genetic control. [PDF]
, 2016 Genetic control aims to reduce the ability of insect pest populations to cause harm via the release of modified insects. One strategy is to bias the reproductive sex ratio towards males so that a population decreases in size or is eliminated altogether ...

iNew Medicine, EarlyView.This illustration synthesizes the methods and conclusion of this study, demonstrating that the transfer of mosaic embryos following reimplantation genetic testing for aneuploidy does not increase the risk to postnatal health. ABSTRACT Next‐generation sequencing (NGS) has increased the detection of mosaic embryos during preimplantation genetic testing ...

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development
PROTEOMICS, EarlyView.ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.
