Malignant tumor metastasis is the key factor leading to poor prognosis of patients， and it is a difficult problem to be overcome in the field of tumor therapy. Metabolic reprogramming， as a key link in the regulation of tumor metastasis activity， affects the growth， invasion， and metastasis of tumor cells by changing the metabolic pathways of intracellular substances （such as glucose， amino acids， lipids， and nucleotides）. In particular， metabolic reprogramming plays a key role in the multistage linked steps related to tumor metastasis and can play a crucial role in several key stages of tumor tissue dissociation in situ， hematogenous metastasis， and remote colonization. Malignant tumor cells can selectively adjust their own metabolic state to adapt to the growth conditions of different metastatic microenvironments and colonization sites and then choose the most favorable growth and metabolism strategy. According to the holistic concept of traditional Chinese medicine （TCM）， the metastasis of malignant tumors is generally closely related to the metabolic state of the whole body. One of the advantages of TCM in the treatment of malignant tumors is systemic regulation. With its multi-pathway， multi-target， and multi-component therapeutic characteristics， TCM can effectively control the metastasis of malignant tumors by regulating the degradation of tumor epithelial mesenchymal transformation （EMT） and extracellular matrix （ECM）， anchoring the independent growth of tumor cells and the tumor microenvironment. In this paper， the potential regulatory effects of metabolic reprogramming on the metastasis of malignant tumors were discussed， and the latest research progress of the regulation of metabolic reprogramming by TCM on tumor metastasis was reviewed. At the same time， the key targets of TCM and its bioactive components in the process of tumor metastasis intervention were reviewed. This study aims to provide a more valuable basis and clearer idea for the treatment of malignant tumor metastasis by regulating metabolic reprogramming with TCM.

Ghrelin is a hormone produced by the stomach that regulates energy metabolism after acting on the central nervous system.Cocaine amphetamine-regulated transcriptional peptide(CART)neurons participate in the regulation of feeding behavior and energy balance.It is known that CART neurons are influenced by hormones to regulate energy homeostasis,but whether ghre-lin exerts its pro-appetite function by influencing CART neurons is unknown.Therefore,this study focuses on the role of VMHCART neurons in the regulation of feeding and relative body weight by ghrelin.Firstly,the whole brain expression of CART was determined by immunofluorescence.Then the effect of intraperitoneal injection of ghrelin on the expression of DMHCART neurons was evalua-ted.Finally,the ghrelin was delivered to DMH and the changes of food intake and relative body weight of mice were measured.CART immunoreactive neurons were detected in medial preoptic nucleus(MPA),arcuate nucleus(ARC),dorsomedial hypothalamic nucleus(DMH),thalamic pa-raventricular nucleus(PVT)and raphe nucleus(ROb).Compared with the control group,periph-eral injection of ghrelin significantly increased the expression of DMHC ART immunoreactive neurons(P=0.037 3).DMH long-term injection of ghrelin resulted in an increase in body weight(P=0.004 0)and feed intake(P=0.023 1).The results provide anatomical evidence for the whole brain distribution of CART,which proves that ghrelin affects feed intake and body weight of mice through CART neurons in DMH,suggesting that specific neuron types and regional specificity are involved in ghrelin regulation of feed intake and energy homeostasis.

Background: Insulin resistance (IR) is the key pathological basis of many metabolic disorders. Lack of asialoglycoprotein receptor 1 (ASGR1) decreased the serum lipid levels and reduced the risk of coronary artery disease. However, whether ASGR1 also participates in the regulatory network of insulin sensitivity and glucose metabolism remains unknown. Methods: The constructed ASGR1 knockout mice and ASGR1-/- HepG2 cell lines were used to establish the animal model of metabolic syndrome and the IR cell model by high-fat diet (HFD) or drug induction, respectively. Then we evaluated the glucose metabolism and insulin signaling in vivo and in vitro. Results: ASGR1 deficiency ameliorated systemic IR in mice fed with HFD, evidenced by improved insulin intolerance, serum insulin, and homeostasis model assessment of IR index, mainly contributed from increased insulin signaling in the liver, but not in muscle or adipose tissues. Meanwhile, the insulin signal transduction was significantly enhanced in ASGR1-/- HepG2 cells. By transcriptome analyses and comparison, those differentially expressed genes between ASGR1 null and wild type were enriched in the insulin signal pathway, particularly in phosphoinositide 3-kinase-AKT signaling. Notably, ASGR1 deficiency significantly reduced hepatic gluconeogenesis and glycogenolysis. Conclusion The ASGR1 deficiency was consequentially linked with improved hepatic insulin sensitivity under metabolic stress, hepatic IR was the core factor of systemic IR, and overcoming hepatic IR significantly relieved the systemic IR. It suggests that ASGR1 is a potential intervention target for improving systemic IR in metabolic disorders.
