Advances in research on mechanism of lactate dehydrogenase B in tumors / 中国药科大学学报

ABSTRACT

@#Increased glycolysis is a major feature of metabolic reprogramming in cancer.Glycolysis provides not only energy for cancer cells but also necessary precursors for biosynthesis, which is important for promoting tumor growth.Cancer cells meet their own needs by regulating glycolytic enzymes, which play an active role in promoting cancer survival, metastasis, and invasion.Lactate dehydrogenase (LDH), as a key enzyme in glycolysis, consists of two subunits lactate dehydrogenase A (LDHA) and lactate dehydrogenase B (LDHB).LDHA is known to play a key role in aerobic glycolysis and has been extensively studied, whereas less has been done on LDHB.However, at present, more and more reports have revealed the important effects of LDHB on the progression of various cancers.A large number of studies have shown that LDHB is abnormally expressed in a variety of cancers, which is related to the malignant progression of tumors.The article reviews the research progress of LDHB in recent ten years, including its regulatory mechanism in tumor, its relationship with cancer development and its role as a biomarker in clinical diagnosis of cancer, which provides some insight for further investigation of the mechanism of LDHB in cancer research.
