Meiosis-specific prophase-like pathway controls cleavage-independent release of cohesin by Wapl phosphorylation.

open access: yesPLoS Genetics, 2019
Sister chromatid cohesion on chromosome arms is essential for the segregation of homologous chromosomes during meiosis I while it is dispensable for sister chromatid separation during mitosis.

Predicting the transmission trend of respiratory viruses in new regions via geospatial similarity learning

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2023
The outbreak and spread of COVID-19 remind us again of the devastating attack that human-to-human transmitted respiratory infectious diseases (H-HRIDs) bring to global economics and public health.

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains

open access: yesCytoskeleton, EarlyView.
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.

Diagnosis and Management of Prenatal Hereditary Pyropoikilocytosis

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Hereditary pyropoikilocytosis (HPP) is a severe hemolytic anemia caused by variants in SPTA1, SPTB, and EPB41. These weaken horizontal interactions in the erythrocyte cytoskeleton, causing membrane fragmentation and splenic sequestration. It will readily cause fetal anemia and often hydrops fetalis. Prenatal diagnosis requires first ruling out

Mining Alzheimer's Interactomes, Macromolecular Complexes and Pathways for Drug Discovery

open access: yesPROTEOMICS, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative disorder that leads to dementia. Many cases are diagnosed annually and there is no currently available cure. Understanding the underlying disease biology of AD through the study of molecular networks, particularly by mapping clinical variants to tissue‐specific interactomes and ...

Two mechanisms repress cyclin B1 translation to maintain prophase arrest in mouse oocytes

open access: yesNature Communications
In mammals, oocytes are arrested in prophase of meiosis I for long periods of time. Prophase arrest is critical for reproduction because it allows oocytes to grow to their full size to support meiotic maturation and embryonic development. Prophase arrest

Ecotoxicological Evaluation of the Antimicrobial Butylparaben in Edaphic Organisms Using Multiple Biomarkers

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Butylparaben (BuP) recurrently contaminates soils worldwide, mainly by incorporating sewage sludge into cultivated areas, using wastewater in irrigation, and leaching contaminated soils. However, there are few studies on the ecotoxicological effects of this paraben on edaphic organisms.

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

An MCM family protein promotes interhomolog recombination by preventing precocious intersister repair of meiotic DSBs.

open access: yesPLoS Genetics, 2019
Recombinational repair of meiotic DNA double-strand breaks (DSBs) uses the homologous chromosome as a template, although the sister chromatid offers itself as a spatially more convenient substrate.
