Recent Research on Flaxseed and Breast Cancer Prevention
The recent study featured in Microbiology Spectrum provides valuable insights into how flaxseed may prevent breast cancer by interacting with our body’s microbiome. Researchers have discovered that components in flaxseed, specifically lignans, significantly influence the gut microbiota and the expression of microRNAs (miRNAs) in the mammary gland, which play a crucial role in regulating genes linked to cancer.
Lignans are fiber-associated compounds abundantly found in flaxseed and known for their potential health benefits, including anti-cancer properties. The study highlights that these compounds require transformation by gut bacteria to exert their biological effects. “The gastrointestinal microbiota plays an important role in modifying many components of our diet to impact human health,” explains Jennifer Auchtung, Ph.D., Assistant Professor at the University of Nebraska–Lincoln and the editor who coordinated the review of the paper. This interaction between diet and microbiota not only affects general health but also specific pathways involved in cancer development.
Pivotal Findings
A key finding from the study is the impact of dietary flaxseed on cecal microbiota composition and miRNA profiles in the mammary gland. These miRNAs regulate many pathways linked to critical cancer processes like cell proliferation and migration. Elena M. Comelli, Ph.D., Associate Professor at the University of Toronto and the study’s corresponding author, noted, “We found correlations between diets enriched in flaxseed, cecal microbiota composition, and miRNA profiles in the mammary gland that regulate many pathways, including those involved in cancer development.”
The research also involved young female mice to examine how flaxseed consumption affects gut microbiota and mammary gland miRNA expression. Researchers discovered that flaxseed lignans prompt specific miRNA responses. These responses modify the relationship between the microbiota and mammary gland towards a non-cancerous state. This finding indicates significant potential for dietary flaxseed to change microbiota-miRNA interactions in a way that could lower breast cancer risk.
This groundbreaking study supports further exploration of the microbiota as a new target for breast cancer prevention via dietary interventions. By studying the interactions between diet, gut microbiota, and gene expression regulation in the mammary gland, researchers are identifying new ways to reduce breast cancer risk.

Understanding Microbiota and miRNAs in Breast Health
The human gut microbiota is a complex and dynamic community of microorganisms that plays a crucial role in our overall health, impacting everything from digestion to immune function. In recent years, researchers have begun to understand the profound influence of the gut microbiota on distant organs, including the mammary glands. This interaction is particularly significant in the context of breast cancer, where the regulation of gene expression by microRNAs (miRNAs) can influence cancer development.
What are MicroRNAs?
MicroRNAs are small, non-coding RNAs that help regulate gene expression post-transcriptionally. They can inhibit or degrade target mRNAs, thereby controlling the activity of various genes, including those involved in cell growth, division, and death. In the breast, certain miRNAs are responsible for regulating pathways that can lead to cancer if dysregulated.
The study published in Microbiology Spectrum offers new insights into how flaxseed affects these critical components of our biology. By altering the composition of the gut microbiota, flaxseed consumption leads to changes in the miRNA profiles expressed in the mammary gland. These miRNAs, in turn, have the potential to regulate genes that are directly involved in cancer-related processes, such as cell proliferation and migration.
Flaxseed Lignans and Microbiota
A key aspect of the study’s findings is the interaction of flaxseed’s lignans with the microbiota. This interaction produces bioactive metabolites that can influence miRNA expression. These dynamics highlight the potential of dietary flaxseed to modulate the gut-mammary gland axis. This modulation may help prevent the onset and progression of breast cancer. Elena M. Comelli, Ph.D., notes, “Our research uncovers a link between mammary gland miRNA expression and the gut microbiota in young female mice. We found that this relationship is modifiable via a dietary intervention.”
These results deepen our understanding of how diet influences breast health. They suggest that altering gut microbiota through diet could be a viable strategy to reduce breast cancer risk. This approach proactively influences key regulatory pathways before they lead to disease. It underscores the importance of preventative nutritional strategies in combating cancer.

Lignans’ Role in Cancer Prevention
Lignans are chemical compounds found in high concentrations in flaxseed. They are known for their phytoestrogenic properties and potential role in cancer prevention, including breast cancer. A Microbiology Spectrum study highlights the importance of lignans. They influence the gut microbiota and miRNA profiles in the mammary gland.
Flaxseed lignans are metabolized by gut bacteria into enterolignans, such as enterodiol and enterolactone. These metabolites exhibit estrogenic activities. They can help modulate hormone balance in the body. Hormonal regulation is crucial in breast cancer, as estrogen levels are linked to the risk and progression of hormone-dependent cancers.
The metabolism of lignans allows these compounds to impact miRNA expression in the mammary gland. This relationship was a focal point in the study. It highlights how dietary lignans can modulate gene expression pathways. These pathways are associated with tumor suppression and cancer cell proliferation. “Importantly, we found that lignan components generate specific miRNA responses in the mammary gland,” notes Elena M. Comelli, Ph.D. “These miRNAs are involved in pathways that could potentially be exploited to reduce breast cancer risk.”

Research supports these findings. Studies have linked high concentrations of circulating lignans with reduced breast cancer mortality, especially in postmenopausal women. The biological activities of lignans include anti-proliferative and pro-apoptotic effects. These contribute to their protective role against cancer development.
The interaction between dietary lignans and the microbiota suggests a larger role of gut health in cancer prevention. This underscores the potential of dietary strategies targeting gut microbiome composition to mitigate cancer risks.
By understanding the role of lignans and their interaction with the gut microbiota, we can appreciate how flaxseed may contribute toward cancer prevention. This opens up possibilities for dietary recommendations and interventions. These could help individuals at high risk of breast cancer manage their health proactively through nutrition.
