Most of the hypodermis of a rhabditid nematode such as Caenorhabditis elegans is a single syncytium. The size of this syncytium (as measured by body size) has evolved repeatedly in the rhabditid nematodes. Two cellular mechanisms are important in the evolution of body size: changes in the numbers of cells that fuse with the syncytium, and the extent of its(More)
BACKGROUND Breast carcinoma and precancer are thought to start in the lining of the milk duct or lobule, yet until recently, we have not had direct access to this area other than by blindly removing tissue by core biopsy or fine-needle aspiration. Fiberoptic ductoscopy (FDS) is an emerging technique allowing direct visual access to the ductal system of the(More)
Dietary genistein, a natural flavone compound found in soy, has been proposed to be responsible for the low rate of breast cancer in Asian women. The cellular mechanisms of genistein's chemopreventive effects in vio have been largely unexplored. In our previous studies, we found that genistein exerted pronounced antiproliferative effects on both estrogen(More)
p21/waf1/cip1 and mdm-2 are downstream effectors of p53. p21 plays a major role in negatively regulating cell-cycle progression, while mdm-2 inhibits p53 effects, and its role has been implicated in oncogenesis. In this study, we investigated the expression profiles of p21, mdm-2 and p53 in human breast-carcinoma tissues. The aim was to determine whether a(More)
To identify more therapeutic targets and clarify the detailed mechanisms of Pseudomonas aeruginosa-mannose-sensitive hemagglutinin (PA-MSHA) on breast cancer cells both in vitro and in vivo. PA-MSHA was administered to epidermal growth factor receptor (EGFR)-positive human breast cancer cell lines MDA-MB-231HM and MDA-MB-468 in vitro and to mice bearing(More)
In addition to the role in regulating leukocyte trafficking, chemokines recently have been shown to be involved in cancer growth and metastasis. Chemokine network in tumor neovascularity may be regulated by decoy receptors. Duffy antigen receptor for chemokines (DARC) is a specific decoy receptor binding with the angiogenic CC and CXC chemokines. To(More)
Human breast carcinoma is biologically heterogeneous, and its clinical course may vary from an indolent slowly progressive one to a course associated with rapid progression and metastatic spread. It is important to establish prognostic factors which will define subgroups of patients with low vs high risk of recurrence so as to better define the need for(More)
Genistein, a natural flavone found in soy has been postulated to be responsible for lowering the rate of breast cancer in Asian women. Our previous studies have shown that genistein exerts multiple suppressive effects on both estrogen receptor positive (ER+) as well as estrogen receptor negative (ER-) human breast carcinoma lines suggesting that the(More)
PURPOSE Tumor-specific DNA has recently been detected in the plasma of lung, head and neck, breast, and colon cancer patients. Detection of tumor-specific genetic materials in cancer patients at sites distant from the tumor, such as in the blood, may provide a unique and valuable tumor marker for diagnosis and prognosis. EXPERIMENTAL DESIGN The present(More)
BACKGROUND Sentinel lymph node biopsy (SLNB) has become an alternative procedure of axillary lymph node dissection (ALND) with a lower risk of significant operative morbidity. The primary aim of the present study was to evaluate the morbidity and quality-of-life (QoL) after SLNB or ALND. The second aim was to analyze whether the number of SLNs removed was(More)
