The signaling pathway of the receptor tyrosine kinase MET and its ligand hepatocyte growth factor (HGF) is important for cell growth, survival, and motility and is functionally linked to the signaling pathway of VEGF, which is widely recognized as a key effector in angiogenesis and cancer progression. Dysregulation of the MET/VEGF axis is found in a number(More)
Expression of the 'A' and 'B' forms of progesterone receptor (PR), in an appropriate ratio is critical for normal mammary development. As such, mammary glands of PR-A transgenic mice, carrying additional 'A' form of PR as transgene, exhibit morphological and histological characteristics associated with transformation. Accordingly, in the present studies, we(More)
Mammary development and tumorigenesis are profoundly influenced by signaling pathways under the control of c-erbB2/c-neu and estrogen receptor alpha (ERalpha). Signaling through ERalpha is essential for ductal growth during puberty. In mice overexpressing wild-type c-neu in mammary epithelial cells, Tg (c-neu), ductal growth is impaired. An impeded(More)
BACKGROUND The family of inhibitor of differentiation/DNA binding (Id) proteins is known to regulate development in several tissues. One member of this gene family, Id-1, has been implicated in mammary development and carcinogenesis. Mammary glands contain various cell types, among which the luminal epithelial cells are primarily targeted for proliferation,(More)
A delicate balance in estrogen and progesterone signaling through their cognate receptors is characteristic for the physiologic state of the endometrium, and a shift in receptor isotype expression can be frequently found in human endometrial pathology. In this study, using a transgenic mouse model, we examined the mechanisms whereby alterations in(More)
With the convenient of mobile device, mobile users are able to “pull” or “push” the mobile message at anytime and anywhere. The power of mobile message has turned into an important marketing power. However, how to utilize the availability and the quick-viewing convenience of mobile message to match the personal needs are not(More)
A series of subtype selective sphingosine 1-phosphate receptor 1 (S1P(1)) antagonists are disclosed. Our high-throughput screening campaign revealed hit 1 for which an increase in potency and mouse oral exposure was achieved with minor modifications to the chemical scaffold. In vivo efficacy revealed that at high doses compounds 12 and 15 inhibited tumor(More)
