Effect of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on the immune system maternal-fetal interface during palatal development.

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is an important environmental pollutant that disturbs the immune balance of the maternal-fetal interface (MFI) and is also a common environmental factor for the formation of cleft palate (CP).

Fifteen C57BL/6J mice were randomly assigned to three groups: control group, TCDD group, and TCDD plus Freund's complete adjuvant (FCA) (TCDD + FCA) group.

Wogonin suppresses proliferation, invasion and migration in gastric cancer cells via targeting the JAK-STAT3 pathway.

Wogonin is a compound extracted from the medicinal plant Scutellaria baicalensis Geogi and has been found to exert antitumor activities in a variety of malignancies.
