Biological role of metabolic reprogramming of cancer cells during epithelial‑mesenchymal transition (Review)

: Epithelial‑mesenchymal transition (EMT) is required for the distant metastasis of tumors. The degree of tumor malignancy increases as EMT progresses. Notably, the biology of tumor cells differs from that of normal cells, with regards to characteristics and energy metabolism mechanisms; abnormal glucose metabolism, excessive accumulation of fatty acids and other metabolic disorders occur in metastatic tumors. Previous studies have confirmed that the regulation of tumor cell metabolism can affect tumor metastasis and some findings have resulted in novel clinical applications. The present review aimed to provide a basis for treatments targeting the tumor EMT process and metabolic reprogramming.
