The role of diet in the prevention of breast cancer is widely accepted, yet little is known about how its biological effects mitigate susceptibility to this disease. Soy consumption is associated with reduced breast cancer risk in women, an effect largely attributed to the soy isoflavone genistein (Gen). We previously showed reduced incidence of chemically(More)
Diet-mediated changes in transcriptional programs that promote the early differentiation of the mammary gland may lead to reduced breast cancer risk. The disparity in adult breast cancer incidence between Asian women and Western counterparts is attributed partly to high soy food intake. Here, we conducted genome-wide profiling of mammary tissues of weanling(More)
The linkage of nutrition and cancer prevention is an intriguing concept that is gaining widespread support. Here, we investigated the influence of developmental context on dietary protection against tumorigenesis initiated by the direct-acting carcinogen N-methyl-N-nitrosourea (NMU), and examined potential mechanisms underlying these effects. Rats were(More)
The mammary gland is composed of two major cellular compartments: a highly dynamic epithelium that undergoes cycles of proliferation, differentiation and apoptosis in response to local and endocrine signals and the underlying stroma comprised of fibroblasts, endothelial cells and adipocytes, which collectively form the mammary fat pad. Breast cancer(More)
Breast cancer is the leading cause of cancer deaths in women. Diet and lifestyle are major contributing factors to increased breast cancer risk. While mechanisms underlying dietary protection of mammary tumor formation are increasingly elucidated, there remains a dearth of knowledge on the nature and precise actions of specific bioactive components present(More)
BACKGROUND Krüppel-like factor 9 (KLF9) is a transcriptional regulator of uterine endometrial cell proliferation, adhesion and differentiation; processes essential for pregnancy success and which are subverted during tumorigenesis. The network of endometrial genes controlled by KLF9 is largely unknown. Over-expression of KLF9 in the human endometrial cancer(More)
G-banded chromosomes of primary cultures taken from mucosal epithelium adjacent to esophageal cancer (EC) were first analyzed. Consistent chromosomal changes, i.e. marker chromosomes, appeared in 2 of seven specimens of esophageal epithelium. Some of the marker chromosomes are very similar to those found in EC8501 cell line. These results imply that the(More)

An esophageal cancer cell line EC8501 was established by tissue culture technique in vitro. Biologic appraisements demonstrated that this cell line was certainly a malignant one. The authors counted chromosome number of 1,284 cells from 10 to 30 passages and discovered that the modal chromosome number was 46 in 10 and 13 passages, 47 in 14 passage and 65 or(More)
Breast cancer risk is highly modifiable by diet; however, mechanisms underlying dietary protection against mammary tumorigenesis remain poorly understood. A proportion of breast carcinomas is associated with deregulation of beta-catenin stability and amplification of c-Myc expression. We recently showed that dietary exposure to the soy isoflavone genistein(More)
