BHLHE40 Cooperates with GATA2/3 to Control Human Syncytiotrophoblast Lineage Differentiation

open access: yesAdvanced Science, EarlyView.
BHLHE40 interacts directly with GATA2 and GATA3 and co‐occupies genomic loci critical for STB differentiation and function. BHLHE40 also affects GATA2/3 binding at enhancer and promoter regions. Moreover, BHLHE40 is potentially involved in genome‐wide remodeling of H3K4me3 and H3K27ac chromatin landscapes through GATA2/3 recruitment, activating ...

Placenta Ingestion Enhances Analgesia\ud Produced by Vaginal/Cervical\ud Stimulation in Rats [PDF]

open access: yes, 1986
Ingestion of placenta has previously been shown to enhance opiate-mediated analgesia (measured as tail-flick latency) induced either by morphine injection or by footshock.

Placenta-specific methylation of the vitamin D 24-hydroxylase gene: implications for feedback autoregulation of active vitamin D levels at the fetomaternal interface [PDF]

open access: yes, 2009
Plasma concentrations of biologically active vitamin D (1,25- (OH)2D) are tightly controlled via feedback regulation of renal 1-hydroxylase (CYP27B1; positive) and 24-hydroxylase (CYP24A1; catabolic) enzymes.

Synergistic Promotion of Triple‐Negative Breast Cancer Tumorigenesis and Metastasis by Oral Polystyrene Nanoplastics Exposure via Alloprevotella‐Derived Glutamate and Platelet Activation

open access: yesAdvanced Science, EarlyView.
Polystyrene nanoplastics (PS‐NPs) administered via oral exposure accelerate triple‐negative breast cancer (TNBC) progression by synergistically modulating gut microbiota‐derived glutamate production and platelet activation. This study uncovers a pivotal crosstalk between microbial metabolites and platelet‐tumor interactions, offering mechanistic ...

Maternal zinc intakes and homeostatic adjustments during pregnancy and lactation. [PDF]

open access: yes, 2012
Zinc plays critical roles during embryogenesis, fetal growth, and milk secretion, which increase the zinc need for pregnancy and lactation. Increased needs can be met by increasing the dietary zinc intake, along with making homeostatic adjustments in ...

Treating Hearing Loss: From Cochlear Implantation to Gene Therapy

open access: yesAdvanced Science, EarlyView.
Cochlear implantation is the primary treatment for deafness, restoring functional hearing in over a million people. Recently, gene therapy has enabled biological hearing restoration in a small number of patients with OTOF‐related mutations. This perspective evaluates both approaches, concluding that cochlear implants will remain the standard for most ...

Differential expression of microRNA-206 and its target genes in pre-eclampsia [PDF]

open access: yes, 2015
Objectives: Pre-eclampsia is a multi-system disease that significantly contributes to maternal and fetal morbidity and mortality. In this study, we used a non-biased microarray approach to identify novel circulating miRNAs in maternal plasma that may be ...
