Sister chromatid segregation in meiosis II: Deprotection through phosphorylation [PDF]

, 2013
International audienceMeiotic divisions (meiosis I and II) are specialized cell divisions to generate haploid gametes. The first meiotic division with the separation of chromosomes is named reductional division.

Meiosis-specific gene discovery in plants: RNA-Seq applied to isolated Arabidopsis male meiocytes

BMC Plant Biology, 2010
Background Meiosis is a critical process in the reproduction and life cycle of flowering plants in which homologous chromosomes pair, synapse, recombine and segregate. Understanding meiosis will not only advance our knowledge of the mechanisms of genetic

Impact of Methylparaben on Cumulus Cell DNA Integrity and Porcine Oocyte Developmental Competence In Vitro

Journal of Applied Toxicology, EarlyView.
ABSTRACT Parabens (PBs) are compounds widely used as preservatives in personal care products, food, and pharmaceuticals. Methylparaben (MePB) is the most used by different industries due to its chemical properties and low cost. The high daily human exposure to these compounds has raised concerns about their potential effects on health, particularly on ...

Brca2 is involved in meiosis in Arabidopsis thaliana as suggested by its interaction with Dmc1 [PDF]

, 2004
Two BRCA2-like sequences are present in the Arabidopsis genome. Both genes are expressed in flower buds and encode nearly identical proteins, which contain four BRC motifs.

Toxic Effects of Bisphenol A and Its Analogs on Ovarian Structure and Function: A Narrative Review of Ovary‐Focused Studies

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) is a widely used industrial chemical found in polycarbonate plastics and epoxy resins and is recognized for its endocrine‐disrupting properties. Human exposure is common due to its presence in food packaging and everyday products. As BPA use has been restricted, structurally similar compounds such as BPS, BPB, BPAF, and BADGE

Mapping Causal Biology: Mendelian Randomization in the Era of Big Data

Med Research, EarlyView.
Mendelian randomization (MR) leverages genetic variants to mitigate confounding biases in causal inference. This review systematically maps MR's methodological evolution, highlights its expanding applications in epidemiology and drug target validation, and outlines future directions for overcoming current biases through dynamic, multi‐omics, and cross ...

Retinoic acid-induced CYP51 nuclear translocation promotes meiosis prophase I process and is correlated to the expression of REC8 and STAG3 in mice

Biology Open, 2018
Lanosterol 14 α-demethylase (CYP51) plays a crucial role in cholesterol biosynthesis. In gamete development, CYP51 is involved in initiating meiosis resumption in oocytes through its product, meiosis activating sterol (MAS).

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Eliminating separase inhibition reveals absence of robust cohesin protection in oocyte metaphase II

The EMBO Journal
The meiotic segregation pattern to generate haploid gametes is mediated by step-wise cohesion removal by separase, first from chromosome arms in meiosis I, and then from the pericentromere in meiosis II.
