CXCL14 and endometrium neoplasm: Rojas et al. (2012) demonstrated that endometrial tumor can cause pregnancy failure. Kuang et al. (2009) concluded that after embryo implantation, the chemokine (C-X-C motif) ligand 14 (CXCL14) gene can promote the growth and development of trophoblast. However, CXCL14 gene was significantly downregulated in our transcriptome analysis, which may explain the adverse pregnancy outcome associated with T. gondii infection, but perhaps require further experimental confirmation on protein level.
