Fariha Imtiaz is a postdoctoral researcher at Virginia Commonwealth University Massey Comprehensive Cancer Center. She studies advanced glycation end-products (AGEs), harmful molecules formed when sugars react with proteins and fats, and how they influence cancer development. In this Postdoc Portrait interview, she shares her motivations and discusses the real-world impacts of her research.
The Interplay Between Diet, Lifestyle, and Cancer Development
Q | What drew you to molecular biology?
My interest in this field began when I recognized that cancer is shaped not only by genetics but also by long-term metabolic and environmental exposures, which are frequently underappreciated. Throughout my training, I developed a deeper curiosity about how daily factors such as diet and lifestyle influence disease risk at the molecular level.
When I first learned about AGEs, I was surprised by how they connect metabolism, aging, and chronic disease. It was compelling to discover that molecules produced by everyday biological processes and common diets could play a role in cancer development.
This led me to focus on how AGEs affect the tumor microenvironment, particularly through interactions with surrounding tissues, such as fat. I was especially drawn to the translational potential of this work. Understanding these mechanisms opens the possibility of developing practical strategies, including dietary guidance and targeted interventions, to reduce cancer risk. To me, this field is a meaningful way to link basic science with real-world impact.
Q | What scientific problem are you trying to solve?
My research focuses on a simple but important question: How does what we eat influence the development of cancer? AGEs accumulate naturally in the body and are found in foods, particularly those cooked at high temperatures or processed. Their levels also rise due to environmental pollutants, aging, high blood sugar, and sedentary lifestyles. Over time, this buildup causes carbonyl stress, which drives inflammation and contributes to cancer development.
My work examines how AGEs affect the tumor microenvironment, particularly the surrounding fat tissue. Although often seen as passive, fat can actively support cancer cells by supplying energy and signals that promote growth and spread. I aim to determine how AGE exposure enhances this support and alters how cancer cells use and store energy.
I am motivated by the potential for translational outcomes. By understanding how AGEs contribute to cancer, we can identify strategies to disrupt these processes through dietary guidance or targeted interventions, aiming to develop effective prevention strategies and inform public health recommendations and disease prevention efforts.
Altering Lifestyle Factors as a Preventative Cancer Approach
Q | What’s one thing you learned from your research that you didn’t expect?
I was surprised by just how deeply this research ties into the idea of prevention. Prevention is often viewed as general advice, but studying AGEs demonstrated that lifestyle factors can directly affect biological processes associated with cancer.
Seeing how diet-related molecules can alter cellular behavior made the concept of prevention appear more tangible and quantifiable. Prevention, therefore, is not solely about broadly avoiding risk, but about identifying and modifying specific biological processes that contribute to disease progression over time.
It reinforced the idea that modifying these exposures is not merely a recommendation but can significantly influence disease-related pathways. This perspective continues to inform my approach to scientific inquiry.
Q | If your research succeeds, what could it change for science or society?
It may shift the prevailing perspective on cancer risk from being viewed primarily as a genetic and unavoidable condition to one that is also shaped by modifiable everyday exposures that can be systematically understood and managed. By uncovering the role of AGEs in cancer development, this research could establish a stronger scientific foundation for dietary and lifestyle recommendations. It may also inform public health guidelines by clarifying not only the impact of specific foods but also the influence of food preparation methods on long-term health outcomes. This work could generate new research directions by revealing previously underexplored metabolic pathways and inter-tissue interactions. Such insights may facilitate the identification of novel intervention targets, especially those capable of interrupting harmful processes prior to the onset of disease.
More broadly, I aim for this research to advance a preventive approach to cancer, emphasizing risk reduction alongside disease treatment. Demonstrating the connection between daily habits and measurable biological effects could render cancer prevention strategies more practical, personalized, and effective.
Q | What question are you most excited to answer next?
I want to explore whether the effects of AGEs can be reversed or reduced in a meaningful way. To date, my research has examined the accumulation of AGEs and their contribution to cancer-related physiological changes. The subsequent objective is to determine whether reducing AGE exposure, through dietary modification or targeted interventions, can reverse these effects or slow cancer progression. I am especially interested in how adaptable these biological systems might be. If we lower AGE levels, does the tumor environment become less able to support cancer growth? Is it possible to disrupt the signals and energy sources that cancer cells depend on? Finding answers to these questions would shift the research from just understanding risks to actually finding solutions. This could help connect basic science with real-world impact and lay the groundwork for strategies that are both effective and practical for cancer prevention.
