Flexibility in metabolism bestows tenacious viability on cancer

Abstract

Cancer cells display altered metabolism distinct from non-transformed cells, which is correlated closely with malignant biocharacteristics. Flexibility remains the central feature of metabolic alteration, enabling cancer cells to survive and thrive in the challenge of inner and outer environments. In this review, we summarise how cancer reprogrammes its metabolism nimbly and adaptively. To begin with, cancer cells adapt metabolism cunningly to supply sufficient materials and energy for infinite proliferation. Further, cancer cells harness metabolism to maintain appropriate cellular redox status, providing survival benefit rather than impairment on tumor growth. Moreover, cancer can switch between different metabolic types flexibly to handle harsh conditions like hypoxia, nutrient deficiency and metabolic inhibition on the journey for expansion. Last but not least, cancer coordinates metabolism of cancerous or stromal cells well to gain support and escape immune destruction. In a word, metabolic flexibility confers indomitable viability on cancer. Exploring such plasticity will help us gain new insights into cancer pathogenesis and cancer therapy.

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.
