Di (2-ethyl-hexyl) phthalate (DEHP) is a widely used plasticizer. Maternal DEHP exposure inhibits cell proliferation and reduces placentas size, which associates with fetal growth restriction and adulthood diseases. However, the mechanism of placental cell proliferation inhibition by DEHP remains elusive.

Article Synopsis
  • Semiclassical models for nonadiabatic transitions, initiated by Landau and Zener in 1932, are important for studying electron transfer but are difficult to experimentally validate.
  • Using the Hush-Marcus theory, the research investigated thermal electron transfer in mixed-valence complexes and found the Landau-Zener formula remains valid in a broader range of conditions than previously thought.
  • The study reveals that in the intermediate regime, the transition probabilities from both adiabatic and nonadiabatic perspectives align closely, enhancing our understanding of electron transfer in various systems.

Article Synopsis
  • DEHP is a common plasticizer that can cause fetal growth restriction and behavioral issues in mice later in life.
  • Pregnant mice were exposed to DEHP during specific gestation periods, and their offspring underwent tests at puberty and adulthood to evaluate behaviors like anxiety and memory.
  • Results indicated that male offspring exposed during gestation 13-17 days experienced significant impairments in spatial memory, highlighting the gender-specific impact of prenatal DEHP exposure.

The pregnane X receptor is a member of the nuclear receptor superfamily, which heterodimerize with the retinoid X receptor, and is an important regulator of cytochrome P450 3A (CYP3A). Lipopolysaccharide (LPS)-induced downregulation of pregnane X receptor and its target gene cyp3a11 has been well characterized in mouse liver. In the present study, we investigated the effects of LPS on the expressions of pregnane X receptor and its target gene cyp3a11 in mouse intestine.

Lipopolysaccharide (LPS) has been associated with adverse developmental outcomes, including intra-uterine fetal death (IUFD) and intra-uterine growth retardation (IUGR). However, the exact mechanism for LPS-induced IUFD and IURD remains unclear. LPS stimulates macrophages to generate reactive oxygen species (ROS).

Pregnane X receptor (PXR) is a nuclear receptor that regulates cytochrome P450 3A (CYP3A) gene transcription in a ligand-dependent manner. Ethanol has been reported to be either an inducer or an inhibitor of CYP3A expression. In this study, we investigated the effects of chronic ethanol exposure on PXR and P450 3A11 gene expression in mouse liver.

The pregnane X receptor (PXR) is a member of the nuclear receptor superfamily that regulates cytochrome P450 3A (CYP3A) gene transcription in a ligand-dependent manner. Lipopolysaccharide (LPS)-induced downregulation on PXR and cyp3a11 in adult mouse liver has been well characterized. In this study, we investigated the effects of maternal LPS exposure on PXR and cyp3a11 expression in fetal mouse liver.

The cytochrome P450 3A (CYP3A) is a member of the cytochrome P450 monooxygenase superfamily. The multidrug resistance 1 (MDR1) gene belongs to the ATP-binding cassette (ABC) family. Pregnane X receptor (PXR) is a nuclear receptor that regulates its target gene transcription in a ligand-dependent manner.

Pregnane X receptor (PXR) is a member of the nuclear receptor superfamily that regulates target gene transcription in a ligand-dependent manner. Our earlier study indicated that reactive oxygen species contribute to lipopolysaccharide (LPS)-induced down-regulation of PXR and its target gene CYP3A in mouse liver. Melatonin is a powerful endogenous antioxidants.

Pregnane X receptor (PXR) is a member of the nuclear receptor superfamily that regulates target gene transcription in a ligand-dependent manner. The in vivo effects of lipopolysaccharide (LPS) on expression of PXR and its target gene cytochrome P450 3A (CYP3A) in mouse liver were investigated in this study. Mice were injected intraperitoneally with different doses of LPS (0.
