We conducted a multi-institutional, placebo-controlled Phase IIB trial of the lignan secoisolariciresinol diglucoside (SDG) found in flaxseed. Benign breast tissue was acquired by random periareolar fine needle aspiration (RPFNA) from pre-menopausal women at increased risk for breast cancer. Those
Previous studies have shown that dietary flaxseed (FS) can reduce the growth of established human breast tumors in athymic mice with low circulating estrogen concentrations. In this study, we determined the effect of FS compared with pure lignan at the level it is present in FS [secoisolariciresinol
Secoisolariciresinol diglucoside (SDG) is isolated from Linum usitatissimum seeds. The antiproliferative effects of SDG (1) and its derivatives secoisolariciresinol (2) and secoisolariciresinol-4', 4″-diacetate (3) have been evaluated on MCF-7 breast cancer cells and
Breast cancer prevention efforts are focused increasingly on potentially beneficial dietary modifications due to their ease of implementation and wide acceptance. Secoisolariciresinol diglucoside (SDG) is a lignan found in high concentration in flaxseed that may have selective estrogen receptor
Preclinical and correlative studies suggest reduced breast cancer with higher lignan intake or blood levels. We conducted a pilot study of modulation of risk biomarkers for breast cancer in premenopausal women after administration of the plant lignan secoisolariciresinol given as the diglycoside
Our previous studies have shown that dietary flaxseed (FS) can reduce the growth and metastasis of human estrogen receptor negative (ER-) breast cancer in nude mice. The aims of our study were to determine (i) whether the tumor inhibitory effect of FS was due to its oil (FO), lignan
Previous studies showed that flaxseed lignan (secoisolariciresinol diglucoside, SDG) and oil (FO) inhibit established breast tumor growth in athymic mice with or without tamoxifen (TAM) treatment. TAM was found to increase bone mineral content (BMC) and density (BMD) in breast cancer patients. It is
Lariciresinol is a dietary lignan that accounts for a significant portion of the total phytoestrogen intake from Western foods. Recent epidemiological studies suggest that high dietary intake of lignans and lariciresinol is associated with reduced breast cancer risk. However, no causal relationship
The scientific literature contains evidence suggesting that women who have been treated for breast cancer may, as a result of their diagnosis, increase their phyto-oestrogen (PE) intake. In the present paper, we describe the creation of a dietary analysis database (based on Dietplan6) for the
Systemic cytotoxic chemotherapy remains the mainstay of metastatic breast cancer; however, prognosis and overall survival is unfavorable due to inadequate treatment response and/or unacceptable toxicity. Natural compounds and their active metabolites receive increasing attention as possible adjuvant
This study determined the effect of 10% flaxseed (FS) and its components, secoisolariciresinol diglycoside (SDG) and flaxseed oil (FO) alone or in combination (SDG+FO), on the metastasis and recurrence of human breast tumor after excision in nude mice. Mice were injected orthotopically with human
Flaxseed (FS), an oilseed containing high amounts of the phytoestrogen lignan, secoisolariciresinol diglucoside (SDG), and n-3 fatty acid, alpha-linolenic acid-rich oil (FO), has been shown to inhibit the growth of established human breast tumors (MCF-7) in ovariectomized (OVX) athymic mice.
Over the last decade, there has been an increasing interest in using flaxseed (Linum usitatissimum) in diet in order to improve nutritional and health status. Lignans are major components of flaxseed. Therefore an extraction procedure for lignans from flaxseed has been optimized. The influence of
Flaxseed (FS) has a breast tumor-reducing effect, possibly because of its high content of secoisolariciresinol diglucoside (SDG) lignan. Sesame seed (SS) is rich in the lignan sesamin (SES) but is non-protective. Both lignans are metabolized to estrogen-like enterodiol and enterolactone. The
Lignan-rich diet has been linked with reduced breast cancer risk, and experimental studies have supported the hypothesis of lignans as cancer growth inhibiting compounds. However, it has not been clear if these compounds are accessible in the mammary tumor tissue in vivo. In this study, the
