As a multifunctional transcription factor, YY1 regulates the expression of many genes essential for early embryonic development. RTCB is an RNA ligase that plays a role in tRNA maturation and Xbp1 mRNA splicing. YY1 can bind in vitro to the response element in the proximal promoter of Rtcb and regulate Rtcb promoter activity. However, the in vivo regulation and whether these two genes are involved in the mother-fetal dialogue during early pregnancy remain unclear. In this study, we validated that YY1 bound in vivo to the proximal promoter of Rtcb in mouse uterus of early pregnancy. Moreover, via building a variety of animal models, our study suggested that both YY1 and RTCB might play a role in mouse uterus decidualization and embryo implantation during early pregnancy.

Background: Early-onset preeclampsia poses significant risks to maternal and fetal health, necessitating a deeper understanding of its molecular mechanisms and effective therapeutic strategies.
Methods: Utilizing data from genome-wide association study and Mendelian randomization analysis, we investigated the relationship between mitochondrial DNA copy number and preeclampsia. Transcriptome sequencing, in vitro experiments, and animal studies were conducted to explore the roles of SENP3 and SETD7 in preeclampsia pathogenesis.

Objective: This study investigated the relationship of maternal serum uric acid, cystatin C (CysC), and coagulation indices [international normalized ratio (INR) and fibrinogen (FIB)] during pregnancy with clinical features and prognosis of early-onset pre-eclampsia.
Methods: Patients with pre-eclampsia (n = 133) were retrospectively selected, with clinical features and maternal uric acid, CysC, INR, and FIB levels collected. The relationship between clinical features and maternal uric acid, CysC, INR, and FIB was analyzed by Pearson's and Spearman's analyses.

The mechanisms by which vaginal microbiota shape spontaneous preterm birth (sPTB) risk remain poorly defined. Using electronic clinical records data from 74,913 maternities in conjunction with metaxanomic (n = 596) and immune profiling (n = 314) data, we show that the B blood group phenotype associates with increased risk of sPTB and adverse vaginal microbiota composition. The O blood group associates with sPTB in women who have a combination of a previous history of sPTB, an adverse vaginal microbial composition and pro-inflammatory cervicovaginal milieu.

Background: Antenatal care (ANC) is a critical component for improving maternal and newborn health. It provides a platform for essential healthcare services, including health promotion, screening and diagnosis, injury and disease prevention, birth preparedness and preparation for the postnatal period. By implementing timely and appropriate evidence-based practices, ANC can reduce maternal and child morbidity and mortality and optimise overall health and well-being.

Pregnancies in patients with systemic lupus erythematosus (SLE) and those positive for anti-SSA/SSB or antiphospholipid antibodies carry a heightened risk of adverse pregnancy outcomes (APOs), including preeclampsia, preterm birth, and congenital heart block. Among available therapies, hydroxychloroquine (HCQ) plays a pivotal role due to its immunomodulatory and antithrombotic properties, which may help improve pregnancy outcomes. Emerging evidence supports HCQ's role in reducing SLE flares, as well as lowering the recurrence risk of congenital heart block in anti-SSA/SSB-positive pregnancies.
