Recent Research Advances in Mitosis during Mammalian Gametogenesis

Cells, 2019
Mitosis is a highly sophisticated and well-regulated process during the development and differentiation of mammalian gametogenesis. The regulation of mitosis plays an essential role in keeping the formulation in oogenesis and gametogenesis.

Genetic and karyotype divergence between parents affect clonality and sterility in hybrids

eLife, 2023
Asexual reproduction can be triggered by interspecific hybridization, but its emergence is supposedly rare, relying on exceptional combinations of suitable genomes.

RNA Helicase Vasa as a Multifunctional Conservative Regulator of Gametogenesis in Eukaryotes

Current Issues in Molecular Biology, 2023
Being a conservative marker of germ cells across metazoan species, DEAD box RNA helicase Vasa (DDX4) remains the subject of worldwide investigations thanks to its multiple functional manifestations.

Beyond tradition: exploring the non-canonical functions of telomeres in meiosis

Frontiers in Cell and Developmental Biology, 2023
The telomere bouquet is a specific chromosomal configuration that forms during meiosis at the zygotene stage, when telomeres cluster together at the nuclear envelope.

The effect of vitrified ovarian tissue autotransplantation encapsulated with hyaluronic acid hydrogen on VEGF, CD31 and CD34 gene expression in rat

Fiyz̤, 2021
Background: One of the problems after cryopreservation and ovarian tissue transplantation is ischemia followed by follicles mortality. In the present study, hyaluronic acid hydrogel was used to improve angiogenesis in vitrified ovarian tissue ...

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Sexual reproduction and biometry of the non-zooxanthellate papillose cup coral Paracyathus pulchellus

Frontiers in Marine Science, 2022
Basic information on the reproductive biology of many scleractinian corals species is limited or entirely lacking, particularly from temperate zones, though it is essential for a better understanding of their ecology.

CHCHD10 Mitigates Alzheimer's Disease‐Related Phenotypes in Association With Epigenetic Remodeling in Directly Reprogrammed Neurons

Advanced Science, EarlyView.
CHCHD10 loss in Alzheimer's disease is associated with mitochondrial dysfunction, epigenomic disruption, and tau pathology. Restoration of CHCHD10 shifts DNA methylation toward a non‐disease state and reduces tau and amyloid pathology, with KATNAL2 acting as a downstream effector.

Thermal Plasticity of the Kelp Laminaria digitata (Phaeophyceae) Across Life Cycle Stages Reveals the Importance of Cold Seasons for Marine Forests

Frontiers in Marine Science, 2020
Phenotypic plasticity (genotype × environment interaction) is an especially important means for sessile organisms to cope with environmental variation.

eEF1G Orchestrates Translation to Ensure Meiotic Progression in Transcriptionally Quiescent Spermatocytes

Advanced Science, EarlyView.
eEF1G supports translation elongation of meiotic mRNAs in transcriptionally quiescent leptotene and zygotene spermatocytes. Its depletion in germ cells causes meiotic arrest at the zygotene stage, with defective homologous synapsis and unstable recombination intermediates.
