Epigenetic Perspectives on Maternal Gut Microbiota's Impact on Embryonic and Fetal Development

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
This review summarizes how maternal health and nutrition shape gut microbiota via epigenetics to regulate embryonic development. It highlights microbiota‐embryo interactions, disruption by prenatal chemical exposures, and personalized nutrition for disease prevention, offering novel insights and therapeutic targets.

Induction of putative tetraploid larvae and analysis of unfertilized egg storage for burbot (Lota lota)

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract Burbot (Lota lota) are a promising candidate for commercial aquaculture production. Methods for captive culture are well understood, the species is highly regarded for its muscle, roe, liver, and skin, and its resistance to many salmonid pathogens coupled with the species' affinity to trout‐like water quality conditions make burbot an ...

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

Advanced Science, Volume 13, Issue 26, 8 May 2026.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

ZSL Orchestrates Synaptonemal Complex Assembly as a Central Region Scaffold to Ensure Synapsis Fidelity and Crossover Control in Polyploid Meiosis

Advanced Science, Volume 13, Issue 27, 13 May 2026.
A central molecular adaptor, ZSL, is identified that links transverse filaments ZYP1 to central element SCEP1/2 to drive synaptonemal complex assembly in Brassica napus. Loss of ZSL abolishes synaptonemal complex formation, disrupts meiotic chromosome segregation, and markedly increases crossovers, providing mechanistic insight into meiotic fidelity ...

Chromosome segregation and meiotic defects in carriers of chromosomal abnormalities

, 2009
Male carriers of chromosomal abnormalities (CA) are more frequent in the infertile population. These men have higher levels of sperm aneuploidy due to the aberrant segregation of the chromosomes involved in the abnormality. The presence of a CA may also influence the segregation of other chromosomes, in a process known as in interchromosomal effect ...

RNA Modifications: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 5, May 2026.
Types of RNA modification. We have summarized the currently common types of RNA modifications, including ac4C, m6A, m1A, m5C, m3C, m7G, and ψ, and visually characterized their features through structural formulas. The characteristic structures are marked with a background color different from the background color.

Systematic Multiplatform Discovery of Methylation Markers Enables Non‐Invasive Early Detection of Endometrial Cancer

Cancer Science, Volume 117, Issue 5, Page 1412-1421, May 2026.
We identified key endometrial cancer DNA methylation biomarkers (ZNF626, GRIA4, SPDYA) from cervical cells. The model achieved high endometrial cancer sensitivity and detected 92.86% of Stage I endometrial cancers using TCT samples. ABSTRACT Endometrial cancer, the most common gynecological malignancy with an annual increase of 1%–3%, lacks suitable ...

Effects of simulated weightlessness on meiosis. Fertilization, and early development in mice [PDF]

The initial goal was to construct a clinostat which could support mammalian cell culture. The clinostat was selected as a means by which to simulate microgravity conditions within the laboratory, by constant re-orientation of cells with respect to the ...

Fetal Fraction Signatures: A Quality Control Tool to Detect Potentially Confounding Situations in NonInvasive Prenatal Diagnosis of Monogenic Conditions

Clinical Genetics, Volume 109, Issue 5, Page 869-875, May 2026.
Noninvasive prenatal diagnosis for monogenic diseases (NIPD‐M) to detect inherited mutations is performed in parallel with fetal fraction signatures, to detect various anomalies that may compromise diagnosis. An extra regression analysis may be necessary to resolve mosaic situations. ABSTRACT Noninvasive prenatal diagnosis relies on the analysis of the
