PS1 is important for the ␥-secretase cleavages of the Philadelphia, Pennsylvania 19104 amyloid precursor protein (APP), which results in the production of the A␤ peptide of Alzheimer's disease (AD) (De Strooper et al., 1998). Recent reports, however, show that in addition to the classic ␥-secretase cleav-Summary ages of APP defined by the C terminus of various A␤ species, the PS1/␥-secretase sy...

background: use of hormone replacement therapy (hrt) may increase the risk of adult-onset asthma in women. various in vitro studies have reported that estradiol stimulates human mast cell lines causing release of allergic mediators which was not observed in estrogen receptor-alpha (er-alpha) knockout mice. thus, estrogen might be a key element in occurrence of asthma. in the present study, we p...

Obesity is also a main health problem associated with breast cancer incidence and subsequent mortality. Association between obesity and expansion of breast cancer may be due to excessive sex steroid h...

background and objective: breast cancer is the commonest cancer of indian women. estrogen and progesterone expression is seen in benign breast lesions and in breast carcinoma associated with good prognostic parameters and it correlates well with response to hormone therapy. although a lot of studies have been conducted in the past on hormone receptor expression in breast cancer and few have cor...

Breast cancer remains one of the most frequent malignancies in women and primary cause cancer-related death all over world. Hormones tumor biomarkers have been implicated as possible causes prognostic breast cancer. The present study investigated use serum hormonal levels biomarkers; Carcinoembrvonic antigen (CEA), (CA 15-3) for diagnosis Cancer, generation different subtypes using Estrogen rec...
