Successful embryo implantation depends on intricate epithelial-stromal cross-talk. However, molecular modulators involved in this cellular communication remain poorly elucidated. Using multiple approaches, we have investigated the spatiotemporal expression and regulation of serine protease inhibitor Kazal type 3 (SPINK3) in mouse uterus during the estrous(More)
OBJECTIVE To determine Claudin-3 expression and its regulatory factors during embryo implantation. DESIGN Experimental mouse models and cell culture. SETTING University research laboratory. ANIMAL(S) Sexually mature female CD-1 strain mice. INTERVENTION(S) Ovariectomy and treatments. MAIN OUTCOME MEASURE(S) In situ hybridization and(More)
Previously we have screened out Insulin-like Growth Factor Binding Protein 7 (IGFBP7) as a differentially expressed gene in post-implantation uterus versus pre-implantation uterus by suppressive subtractive hybridation. However its function in uterus was not clearly identified. In this research, the expression and function of IGFBP7 during post-implantation(More)
Vitamin A (VA) is required for normal fetal development and successful pregnancy. Excessive VA intake during pregnancy may lead to adverse maternal and fetal effects. Cytochrome P450 26A1 (cyp26a1), a retinoic acid (RA)-metabolizing enzyme, is involved in VA metabolism. It has been shown that cyp26a1 is expressed in female reproductive tract, especially in(More)
Vitamin A (retinol) and its active metabolite, retinoic acid (RA), serve dual roles in the female reproductive tract. Cytochrome P450 26A1 (Cyp26a1), an RA-metabolizing enzyme, is involved in mammalian early pregnancy. In order to investigate the role of RA synthesis and metabolism during embryo implantation, we first investigated the spatiotemporal(More)
Secretory protein proline-rich acid protein 1 (PRAP1) is abundantly expressed in late pregnant uterus. However, regulation and function of PRAP1 in pregnant uterus is still elusive. We firstly reported differential expression of PRAP1 in peri-implantation uteri and its localization in endometrial epithelia. Expression of PRAP1 in uterus was induced by(More)
BACKGROUND We investigated the effect of basal protein expression on trastuzamab response in patients with HER2-positive (HER2(+)) breast cancer who received trastuzamab (T) and in HER2(+) breast cancer cell lines. PATIENTS AND METHODS Expression of cytokeratin (CK) 5/6, CK14, and epidermal growth factor receptor (EGFR) was evaluated after(More)
