Abstract
Breast cancer (BC) is the most often diagnosed cancer among females globally and has become an increasing global health issue over the last decades. Despite the substantial improvement in screening methods for initial diagnosis, effective therapy remains lacking. Still, there has been high recurrence and disease progression after treatment of surgery, endocrine therapy, chemotherapy, and radiotherapy. Considering this view, there is a crucial requirement to develop safe, freely accessible, and effective anticancer therapy for BC. The dietary bioactive compounds as auspicious anticancer agents have been recognized to be active and their implications in the treatment of BC with negligible side effects. Hence, this review focused on various dietary bioactive compounds as potential therapeutic agents in the prevention and treatment of BC with the mechanisms of action. Bioactive compounds have chemo-preventive properties as they inhibit the proliferation of cancer cells, downregulate the expression of estrogen receptors, and cell cycle arrest by inducing apoptotic settings in tumor cells. Therapeutic drugs or natural compounds generally incorporate engineered nanoparticles with ideal sizes, shapes, and enhance their solubility, circulatory half-life, and biodistribution. All data of in vitro, in vivo, and clinical studies of dietary bioactive compounds and their impact on BC were collected from Science Direct, PubMed, and Google Scholar. The data of chemopreventive and anticancer activity of dietary bioactive compounds were collected and orchestrated in a suitable place in the review. These shreds of data will be extremely beneficial to recognize a series of additional diet-derived bioactive compounds to treat BC with the lowest side effects.

Marine fish oil is more potent than plant-based n-3 polyunsaturated fatty acids in the prevention of mammary tumors. J Nutr Biochem 2017; 55:41-52. [PMID: 29413488 DOI: 10.1016/j.jnutbio.2017.12.011] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2017] [Revised: 12/18/2017] [Accepted: 12/21/2017] [Indexed: 12/24/2022]
Abstract
Marine-derived n-3 polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been shown to inhibit mammary carcinogenesis. However, evidence regarding plant-based α-linolenic acid (ALA), the major n-3 PUFA in the Western diet, remains equivocal. The objective of this study was to examine the effect of lifelong exposure to plant- or marine-derived n-3 PUFAs on pubertal mammary gland and tumor development in MMTV-neu(ndl)-YD5 mice. It is hypothesized that lifelong exposure to n-3 PUFA reduces terminal end buds during puberty leading to delayed tumor onset, volume and multiplicity. It is further hypothesized that plant-derived n-3 PUFAs will exert dose-dependent effects. Harems of MMTV-FVB males were bred with wild-type females and fed either a (1) 10% safflower (10% SF, n-6 PUFA, control), (2) 10% flaxseed (10% FS), (3) 7% safflower plus 3% flaxseed (3% FS) or (4) 7% safflower plus 3% menhaden (3% FO) diet. Female offspring were maintained on parental diets. Compared to SF, 10% FS and 3% FO reduced (P<.05) terminal end buds at 6 weeks and tumor volume and multiplicity at 20 weeks. A dose-dependent reduction of tumor volume and multiplicity was observed in mice fed 3% and 10% FS. Antitumorigenic effects were associated with altered HER2, pHER-2, pAkt and Ki-67 protein expression. Compared to 10% SF, 3% FO significantly down-regulated expression of genes involved in eicosanoid synthesis and inflammation. From this, it can be estimated that ALA was 1/8 as potent as EPA+DHA. Thus, marine-derived n-3 PUFAs have greater potency versus plant-based n-3 PUFAs.

Mason JK, Thompson LU. Flaxseed and its lignan and oil components: can they play a role in reducing the risk of and improving the treatment of breast cancer? Appl Physiol Nutr Metab 2014; 39:663-78.

Abstract
Flaxseed (FS), rich in the phytoestrogen lignans and α-linolenic acid-rich oil, has been suggested to have an anticancer effect. Questions remain whether FS and its lignan and oil components are effective in reducing breast cancer risk and tumour growth, and can interact beneficially with breast cancer drugs. To find answers, in vitro, animal, observational, and clinical studies on FS and its lignan and oil components were reviewed. The majority of studies in various rodent models show that 2.5%–10% FS diet or the equivalent amount of lignan or oil reduces tumour growth. Ten percent FS and equivalent lignans do not interfere with but rather increase the effectiveness of tamoxifen (80 mg/day) while the 4% FS oil increases trastuzumab/Herceptin (2.5 mg/kg) effectiveness. Observational studies show that FS and lignan intake, urinary excretion, or serum levels are associated with reduced risk, particularly in postmenopausal women. Lignans reduce breast cancer and all-cause mortality by 33%–70% and 40%–53%, respectively, without reducing tamoxifen effectiveness. Clinical trials show that FS (25 g/day with 50 mg lignans; 32 days) reduces tumour growth in breast cancer patients and lignans (50 mg/day; 1 year) reduces risk in premenopausal women. Mechanisms include decreased cell proliferation and angiogenesis and increased apoptosis through modulation of estrogen metabolism and estrogen receptor and growth factor receptor signalling pathways. More clinical trials are needed but current overall evidence indicates that FS and its components are effective in the risk reduction and treatment of breast cancer and safe for consumption by breast cancer patients.

Abstract
Consumption of diet rich in lignans may decrease the risk of some chronic hormonal conditions such as benign prostatic hyperplasia (BPH). This study investigated whether a lignan-rich extract from flaxseed hulls, LinumLife EXTRA (LLE), could prevent BPH using the testosterone propionate (TP)-induced BPH rat model. Male Wistar-Unilever rats were randomly divided into four groups of 12 rats each: a negative control group fed with control diet and receiving daily subcutaneous injections of corn oil without TP, and three groups fed with control diet (positive control), diet containing 0.5% LLE (LLE 0.5) or 1.0% LLE (LLE 1.0) and receiving daily subcutaneous injections of TP in corn oil. Treatments with diets started 2 weeks before the induction of BPH and were carried out for 5 consecutive weeks. The influence of TP and LLE on body weight (BW), food and water consumptions, and enterolactone (ENL) levels in serum and urine of rats was examined at the end of the 5-week treatment period. TP significantly diminished the mean body weight gain (MBWG) of positive control rats and their food and water consumptions while LLE reduced significantly this MBWG reduction in a dose-dependent manner. The lignan-rich extract significantly inhibited TP-induced prostate size ratio (prostate weight/rat BW) increase in comparison with positive controls (P<.001). This effect was dose dependent. Higher serum and urine levels of ENL correlated well with the dose of extract provided to rats. It was concluded that the lignan-rich flaxseed hull extract prevented the TP-induced BPH indicating it might be beneficial in the prevention of BPH.

Antidepressant-like effect of flaxseed secoisolariciresinol diglycoside in ovariectomized mice subjected to unpredictable chronic stress. Metab Brain Dis 2013; 28:77-84. [PMID: 23263992 DOI: 10.1007/s11011-012-9371-1] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2012] [Accepted: 12/12/2012] [Indexed: 10/27/2022]
Abstract
Secoisolariciresinol diglycoside (SDG), a predominant lignan in flaxseed, has antioxidant activity as a dietary supplement. The purpose of the present study was to investigate the antidepressant-like effect and the possible mechanism of flaxseed SDG when the ovariectomized mice were exposed to the unpredictable chronic mild stress procedure. Chronic stress induced the increases in immobility time in mouse model of despair tests, but administration with SDG (80 and 160 mg/kg, p.o.) for 21 days inhibited these behavioral changes caused by stress in both forced swimming and tail suspension tests. These doses that affected the immobile response did not affect locomotor activity. Moreover, the changes in the serum corticosterone and adrenocorticotropic hormone (ACTH) levels were also measured to explore the SDG-associated regulation of hypothalamus-pituitary-adrenals (HPA) axis. The results indicated that the chronic stress-induced increases in the serum corticosterone and ACTH were reversed by treatment with high doses of SDG. Chronic treatment with SDG also affected the body weight of mice and IL-6, IL1β levels in the frontal cortex. In addition, chronic stress procedure induced a decrease in brain-derived neurotrophic factor (BDNF) expression in the frontal cortex of mice; while treatment with SDG reversed this reduction of BDNF. All these results provide compelling evidence that the behavioral effects of flaxseed SDG in the ovariectomized mice might be related to their modulating effects on the neuroendocrine-immune network and neurotrophin factor expression.
