The recent identification of activating fibroblast growth factor receptor 2 (FGFR2) mutations in endometrial cancer has generated an opportunity for a novel target-based therapy. Here, we explore the therapeutic potential of 2 FGFR inhibitors, the multikinase inhibitor dovitinib (TKI258) and the more selective FGFR inhibitor NVP-BGJ398 for the treatment of endometrial cancer. We examined the ef...
Endometrial cancers exhibit a different mechanism of tumorigenesis and progression depending on histopathological and clinical types. The most frequently altered gene in estrogen-dependent endometrioid endometrial carcinoma tumors is PTEN. Microsatellite instability is another important genetic event in this type of tumor. In contrast, p53 mutations or Her2/neu overexpression are more frequent ...
the effect co-culture of mouse fallopian tube cells on proliferation of human endometrial stem cells
aims: to evaluate the effect of mouse fallopian tube cell co-culture on the proliferation of human endometrial stromal cells. materials and methods: the endometrial cells were collected from the uterus under hysteroscopy. then the cells were isolated withcollagenase type 3 and passed within the filters with 150 and 40 micrometer sizes respectivelyand then the isolated cells were cultured in dme...
The aim of this study was to measure the expression patterns of PGK1 and GRP78 in normal endometrial tissues and endometrial carcinoma, and associations between their combined effects and the pathological features of endometrial carcinoma. We used 30 normal endometrial tissue samples and 130 endometrial carcinoma samples, and separately evaluated PGK1 and GRP78 protein expression by immunohisto...
Inactivating mutations in the PTEN tumor suppressor gene occur in approximately 30-50% of endometrial carcinomas. PTEN is a phosphatase that negatively regulates the phosphoinositide 3-kinase signaling pathway, including the downstream effector AKT. To evaluate the role of PTEN in endometrial growth regulation, we expressed wild-type or mutant PTEN in endometrial carcinoma cell lines. As expect...
Endometrial cancer is a heterogeneous disease. Type I cancers are hormonally driven, typically present with a low grade at an early stage, and are of endometrioid histology. These cancers are often cured by surgery, and the rate of recurrence is low. Type II cancers are less differentiated, often appear at a later stage, and are of serous, clear cell, or high grade endometrioid histology. The r...
PURPOSE Although there is considerable information on the molecular aberrations associated with endometrial cancer, very little is known of the changes in gene expression associated with endometrial hyperplasia. EXPERIMENTAL DESIGN To address this, we have compared the level of expression of estrogen-regulated genes and components of the insulin-like growth factor I (IGF-I) signaling pathway ...
Abnormal uterine bleeding can severely affect the quality of life for women. After menstruation, the endometrium must adequately repair to limit and stop bleeding. Abnormal uterine bleeding may result from incorrect or inadequate endometrial repair after menstruation. Previous studies have shown an important contribution of activin to skin wound healing, with severely delayed wound repair obser...
We have demonstrated the intracellular expression of sex hormone-binding globulin (SHBG) exon VII splicing variant mRNA in human uterine endometrial cancer using the reverse transcription-PCR-Southern blot and DNA sequencing analyses. Analysis of the missing base pairs proved that they corresponded to the entire exon VII, which is considered to encode a portion of the steroid-binding site, sugg...
