The Role of Aberrant Metabolism in Cancer: Insights Into the Interplay Between Cell Metabolic Reprogramming, Metabolic Syndrome, and Cancer

Abstract

Metabolic syndrome (MetS) is characterized by hyperglycemia, hypertension, dyslipidemia and abdominal obesity. Patients with MetS or other metabolic disorders are more susceptible to cancer development and recurrence and have a worse long-term prognosis. Moreover, the metabolic reprogramming observed in cancer cells has also been described as one of the new hallmarks of cancer. Thus, aberrant metabolism has been proposed as an important risk factor for cancer. Chronic inflammation, reactive oxygen species (ROS), and oncogenic signaling pathways are considered as main potential triggers. Considering the strong association between metabolism and cancer, metabolism-modulating drugs, including metformin and statins, as well as adopting a healthy lifestyle, have been extensively investigated as strategies to combat cancer. Furthermore, strategies that interfere with the metabolic rewiring of cells may also have potent anti-cancer effects. In this article, we provide a comprehensive review of current knowledge on the relationship between aberrant metabolism and cancer and discuss the potential use of metabolism-targeting strategy for the treatment of cancer.

p66Shc Deficiency in Chronic Lymphocytic Leukemia Promotes Chemokine Receptor Expression Through the ROS-Dependent Inhibition of NF-κB

“…The tight control of intracellular ROS appears therefore as a promising therapeutic strategy to overcome aberrant NF-κB activation. It is however noteworthy that the high reactivity of ROS makes them harmful to protein, DNA, and lipids, as witnessed by their tight control by antioxidant systems that maintain ROS homeostasis ( 58 ). Direct pharmacological modulation of ROS-modulating enzymes might therefore lead to uncontrolled side effects that make this approach hardly feasible ( 59 ).…”

Impact of Pelvic Radiation Therapy for Prostate Cancer on Global Metabolic Profiles and Microbiota-Driven Gastrointestinal Late Side Effects: A Longitudinal Observational Study

“…For example, metabolic reprogramming in response to hypoxia and malnutrition is one of the hallmarks of cancer and may occur through aberrant overactivation of oncogenes or signaling pathways, which occur in PCa. 9 Hypoxia impairs tissue response to radiation. Historically this effect has been attributed to a decrease in oxygen radical formation during radiation.…”

Tumor cell malignancy: A complex trait built through reciprocal interactions between tumors and tissue-body system

“…A constellation of metabolic risk factors collectively referred to as the metabolic syndrome (MetS) includes as main components: abdominal obesity, hyperglycemia, high blood pressure, hypertriglyceridemia, low HDL cholesterol levels, and central circadian dysrhythmia. Among these conditions, obesity and hyperglycemia link MetS to cancer via several mechanisms including inflammation, oxidative stress, immunity and cell signaling pathways ( Yu et al., 2020 ). For example, hyperglycemia promotes hepatocellular carcinoma cells survival and progression by inducing the Wnt/β-catenin signaling pathway ( Chouhan et al., 2016 ).…”
