CHD8‐Dependent Chromatin Licensing Sustains Trophoblast Stem Cell Transcriptional Programs

open access: yesAdvanced Science, EarlyView.
In this study, Huang et al., identify chromatin remodeler CHD8 as an essential factor in TSC maintenance and placental development. CHD8‐dependent chromatin accessibility supports the occupancy of key trophoblast TFs and is coupled to KMT2A‐associated H3K4me3 deposition at TSC stem and cell cycle genes, providing a permissive chromatin environment for ...

WFS1 Deficiency Impairs PIAS4‐Associated SUMOylation and Increases Ubiquitin‐Mediated Spermatogenesis‐Related Protein Degradation Leading to Testicular Male Infertility

open access: yesAdvanced Science, EarlyView.
The findings establish a critical role for WFS1 in human male fertility. Mechanistically, WFS1 interacts with PIAS4 to promote the SUMOylation of key spermatogenesis‐associated proteins, which in turn competitively inhibits their K48‐linked ubiquitin‐mediated degradation during spermatogenesis.

Features of the cytokine profile in the structures of chorion and placenta in premature termination of pregnancy

open access: yesPatologìâ, 2020
The placenta is a mirror of pregnancy. The formation of a healthy placenta predetermines embryo-endometrial relationships, which are regulated by cytokines.

Structural Control of Stromal‐Immune Coupling by COL24A1 Underlies Pregnancy Maintenance

open access: yesAdvanced Science, EarlyView.
COL24A1 emerges as a collagen‐associated regulator of maternal‐fetal interface homeostasis. Its deficiency promotes a maladaptive TIMP1‐high stromal state, impaired ECM turnover, collagen accumulation, and stromal–immune dysregulation, contributing to pregnancy loss.

Chorion Villus Biopsy [PDF]

open access: yesClinics in Obstetrics and Gynaecology, 1985
Chorion villus biopsy answers the pressing need for early prenatal diagnosis. The technique is carried out at about 10 weeks gestation and in most instances this tissue is amenable to direct analysis without culture. This technique is particularly suitable for gene probe diagnosis.

High Diagnosis Rate for Nonimmune Hydrops Fetalis With Prenatal Clinical Genome: Expanded Results From the Hydrops‐Yielding Diagnostic Results of Prenatal Sequencing (HYDROPS) Study

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nonimmune hydrops fetalis (NIHF) is characterized by abnormal fluid accumulation in ≥ 2 fetal compartments and may be genetic. The incremental diagnostic yield of prenatal exome sequencing (ES) for NIHF following a negative standard workup was previously explored on 22 cases.

Chorion Characteristics of Sod Webworm Eggs [PDF]

open access: yes, 1972
The egg chorion was investigated for 15 species of sod webworm moths (Lepidoptera: Pyralidae: Crambinae) collected in Tennessee. Liquid plastic was used for surface printing of chorion sculpturing.

Reframing Trisomy 13 and 18 Care: Moving Beyond the Myth of “Incompatibility With Life” in a South African and Low‐and Middle‐Income Country Context

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Trisomy 13 (T13) and trisomy 18 (T18) have historically been described as “lethal” or “incompatible with life,” contributing to diagnosis‐based limitations of care. Contemporary evidence demonstrates greater heterogeneity in survival and outcomes than previously recognized, including among selected children receiving intensive care or cardiac ...

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...
