Two Novel Protein‐Truncating Variants in NLRP2 and Their Functional Impacts on the Subcortical Maternal Complex

Clinical Genetics, EarlyView.
Two deleterious protein‐truncating NLRP2 variants were identified in a patient with female infertility, four early miscarriages, and one failed attempt of intracytoplasmic sperm injection. The variants mediate mRNA decay and alter NLRP2 structure and interactions with other members of the SCMC.

Aarskog Syndrome: Deep Phenotyping and Genomic Landscape of a New Cohort Including Adult Patients

Clinical Genetics, EarlyView.
This study presents the deep phenotyping data of 14 new Aarskog‐Scott syndrome patients with molecular confirmation. ABSTRACT Aarskog‐Scott syndrome (AAS, MIM#305400) is an X‐linked disorder characterized by recognizable facial features, short stature, and genitourinary and skeletal malformations.

Testis‐Specific PDHA2 Is Required for Proper Meiotic Recombination and Chromosome Organisation During Spermatogenesis

Cell Proliferation, EarlyView.
PDHA2, a testis‐specific subunit of pyruvate dehydrogenase, is required for the conversion of pyruvate to acetyl‐CoA. Its absence results in decreased acetyl‐CoA and precursors for metabolites and energy during spermatogenesis. This results in decreased histone acetylation, defective chromosome structure and moderately reduced crossovers, ultimately ...

Decoding the Molecular Landscape of Prepubertal Oocyte Maturation: GTPBP4 as a Key Driver of In Vitro Developmental Competence

Cell Proliferation, EarlyView.
Transcriptional and translational characteristics during goat oocyte maturation and identification of key factors, including GTPBP4, for prepubertal goat oocyte maturation. ABSTRACT The intricate mechanisms driving oocyte maturation remain only partially understood, especially within the domains of domestic animal reproduction and translational ...

GPD1L‐Mediated Glycerophospholipid Metabolism Dysfunction in Women With Diminished Ovarian Reserve: Insights From Pseudotargeted Metabolomic Analysis of Follicular Fluid

Cell Proliferation, EarlyView.
Our study demonstrated the downregulation of GPD1L and its mediated glycerophospholipid metabolism dysfunction in patients with diminished ovarian reserve. Moreover, we verified that GPD1L knockdown leads to increased cell apoptosis and mitochondrial dysfunction of KGN cells, as well as impaired oocyte quality.

RNF187 Facilitates Proliferation and Migration of Human Spermatogonial Stem Cells Through WDR77 Polyubiquitination

Cell Proliferation, EarlyView.
RNF187 mediates the polyubiquitination and subsequent degradation of WDR77, reduces H4R3me2s catalysed by the WDR77/PRMT5 complex, and derepresses the transcription of EGR1, thereby promoting the proliferation and migration of human SSCs. ABSTRACT The E3 ubiquitin ligase RNF187, also known as RING domain AP1 coactivator‐1, is a member of the RING ...

Revitalising Aging Oocytes: Echinacoside Restores Mitochondrial Function and Cellular Homeostasis Through Targeting GJA1/SIRT1 Pathway

Cell Proliferation, EarlyView.
ECH protects senescent oocytes by stabilising the cytoskeleton, restoring mitochondrial function, reducing oxidative stress and maintaining cellular homeostasis, primarily through the GJA1/SIRT1 signalling pathway. ABSTRACT As maternal age increases, the decline in oocyte quality emerges as a critical factor contributing to reduced reproductive ...

YKT6 Is Essential for Male Fertility by Promoting Meiosis Progression During Spermatogenesis of Mice

Cell Proliferation, EarlyView.
Specifically ablating Ykt6 in pre‐meiotic germ cells and meiotic spermatocytes leads to complete sterility and meiotic arrest in conditional knockout male mice. YTK6 is required for stabilising intercellular bridges between spermatocytes due to its key role in maintaining protein homeostasis and vesicular transport‐dependent functions in spermatocytes,

Multiple mating is not driven by size and sperm management in black soldier fly (Hermetia illucens)

Entomologia Experimentalis et Applicata, EarlyView.
We investigated mating in black soldier fly (BSF), Hermetia illucens (Diptera: Stratiomyidae), an important source of animal feed. The number of spermatozoa stored in the spermathecae of females does not change after one, two and three matings of the male. BSF males and females mate multiple times under controlled conditions. The number of sperm in the

SPERM-COUNTS AFTER VASECTOMY

The Lancet, 1973
The letter writers remark upon the discord among clinicians and pathologists shown by the correspondence in this journal following the writers suggestion (March 24 p.663) that semen-counts may be unnecessary provided 20 ejaculations have occurred after an effective vasectomy procedure.
