Article Abstract
Problem: CpG oligodeoxynucleotides (ODNs) can induce immunological changes in non-obese diabetic (NOD) mice and increase embryo loss, but little is known about the mechanism. This study aimed to determine the role of adiponectin in CpG ODN-induced pregnancy failure.
Method Of Study: Oligodeoxynucleotide 1826 was intraperitoneally injected to NOD mice, and ODN 2216, ODN 2006, and ODN 2395 were used to stimulate human trophoblast cell lines to investigate adiponectin expression patterns and its possible effects on trophoblast function.
Results: CpG ODNs downregulated adiponectin via the cJun N-terminal kinase signaling pathway and led to increased embryo loss (from 6.9 to 33.3%). ODN 2006 impaired human trophoblast cell migration, which was successfully rescued by adiponectin treatment.
Conclusion: CpG ODNs decreased placental adiponectin expression in NOD mice and impaired human trophoblast function and was associated with increased embryo loss. Adiponectin may therefore play an important protective role in the prevention of bacteria-induced pregnancy failure.

Purpose: Prior studies in fresh embryo transfer IVF cycles have associated elevated serum progesterone level on day of ovulatory trigger, particularly if ≥ 1.5 ng/ml, with decreased pregnancy rates. A similar association has been found in intrauterine insemination (IUI) cycles using gonadotropins for ovulation induction.

Ovarian steroid hormones-estrogen and progesterone-play a central role in regulating epithelial-stromal interactions in the uterus. These interactions are critical for uterine function, including endometrial receptivity, implantation, and decidualization. These interactions involve complex signaling crosstalk between the uterine epithelium and the underlying stroma, with dynamic cell population-specific roles.

Human pregnancy is a complex condition that poses significant challenges for women due to the necessity of a uterus for key processes such as fertilization, embryo implantation, fetal development, and childbirth. These processes are governed by immunological factors and accompanied by various physiological changes. For a successful pregnancy, maternal immune reprogramming is crucial because the developing embryo is considered a semi-allograft.

Cap Methyltransferase 1 (CMTR1) facilitates the addition of a 5' methyl cap on eukaryotic mRNA molecules. Using a knock-out (KO) allele, we demonstrate that CMTR1plays an essential role during gastrulation. In the absence of CMTR1, mutant embryos undergo early lethality, arresting prior to organogenesis with severe developmental delay apparent at E7.

Cardiogenesis relies on the integrated interplay between cardiac transcription factors and signaling pathways. Here, we uncover a role for type IIA procollagen (IIA), an extracellular matrix (ECM) protein encoded by an alternatively spliced transcript, encoding a N-terminal cysteine-rich domain, as a critical regulator in a cardiac gene regulatory feedback loop. The cysteine-rich domain of IIA protein was previously reported to interact with bone morphogenetic proteins (BMPs) and transforming growth factors-beta (TGFβ) in in vitro binding assays and acts as a BMP antagonist in amphibian embryo assays.
