| abstractText | Vangl1 and Vangl2 are homologous genes belonging to the group of highly conserved planar cell polarity proteins. It has been shown that Vangl1 and Vangl2 are essential for embryonic development, cell adhesion, migration and polarity. We examined the expression of Vangl1 and Vangl2 in the uterus of mice during early pregnancy. They are upregulated in the endometrium of peri-implantation and reached the peak on D5. Vangl1 mRNA is widely distributed in the luminal epithelium, glandular epithelium and stromal cells in the endometrium, while its protein only appeared in the stromal cells. The localization of Vangl2 protein overlapped with its mRNA. In addition, expression of Vangl1 in the endometrium of pseudopregnant mice was lower than that of pregnant mice, whereas the level of Vangl2 was not significantly different, suggesting that expression of Vangl1 is induced by embryo. Further study showed that implantation would be suppressed after silencing expressions of Vangl1 and Vangl2 by uterine injection with antisense oligonucleotides. These findings suggest that Vangl1 and Vangl2 may play a key role in the embryo implantation of mice. |
