Deconvolution at the single-cell level reveals ovarian cell-type-specific transcriptomic changes in PCOS

Reproductive Biology and Endocrinology
Background Polycystic ovary syndrome (PCOS) is one of the most common reproductive endocrine disorders in females of childbearing age. Various types of ovarian cells work together to maintain normal reproductive function, whose discordance often takes ...

Limit theorems for Markov processes indexed by continuous time Galton--Watson trees [PDF]

, 2011
We study the evolution of a particle system whose genealogy is given by a supercritical continuous time Galton--Watson tree. The particles move independently according to a Markov process and when a branching event occurs, the offspring locations depend ...

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

Advanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Parental and offspring factors in offspring’s weight-loss efforts

Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity, 2016
Although weight-loss efforts in non-overweight adolescents and young adults are quite common, the relation between parental and offspring factors related to this behavior remains unclear. This study assessed the parental and offspring factors related to offspring's weight-loss efforts according to offspring's weight status.Data pertaining to weight ...

Epigenetic Down-Regulation of Sirt 1 via DNA Methylation and Oxidative Stress Signaling Contributes to the Gestational Diabetes Mellitus-Induced Fetal Programming of Heart Ischemia-Sensitive Phenotype in Late Life. [PDF]

, 2019
Rationale: The incidence of gestational diabetes mellitus (GDM) is increasing worldwide. However, whether and how GDM exposure induces fetal programming of adult cardiac dysfunctional phenotype, especially the underlying epigenetic molecular mechanisms ...

USP9X as a Candidate Mediator of Prenatal Aspirin‐Induced Ovarian Reserve Reduction in Offspring Mice

Advanced Science, EarlyView.
This study suggests that prenatal aspirin exposure is associated with reduced ovarian reserve in offspring, associated with HDAC1‐linked epigenetic downregulation of Usp9x as a candidate mechanism. These preclinical findings provide new insights into fetal‐origin ovarian disorders and contribute to the evidence base concerning aspirin's gestational ...

KAS-seq profiling captures transcription dynamics during oocyte maturation

Journal of Ovarian Research
In fully grown oocytes, the genome is considered to be globally transcriptionally silenced. However, this conclusion is primarily derived from the results obtained through immunofluorescence staining or inferred from the highly condensed state of ...

Chromatin Topology Reconfiguration Orchestrates Thermotolerant Male Fertility via GhAL5 in Cotton

Advanced Science, EarlyView.
This study investigates cotton’s high‐temperature (HT) response using multi‑omics. Dynamic 3D genome changes drive expression bias affecting male fertility. The tolerant line shows controlled chromatin dynamics, while the sensitive line exhibits overactivation.

Biallelic BRCA2 variants induce premature ovarian insufficiency by impaired meiotic homologous recombination

Communications Biology
The DNA damage response plays a pivotal role in ovarian aging. Breast cancer susceptibility gene 2 (BRCA2), which participates in homologous recombination (HR), is a key regulator of natural menopause. Rare BRCA2 variants have been identified in patients

Why We Should Create Artificial Offspring: Meaning and the Collective Afterlife [PDF]

, 2018
This article argues that the creation of artificial offspring could make our lives more meaningful. By ‘artificial offspring’ I mean beings that we construct, with a mix of human and non-human-like qualities.
