摘要： Aminopeptidase N(APN/CD13), a Zn2+-dependent ectopeptidase localized on the cell surface, is widely considered to influence the invasion of tumor cells. We found that boroleucine and dino-leucine borate exhibited a strong inhibitory effect on the enzyme activity of aminopeptidase N. The tested assay indicated that both compounds had an anti-proliferative effect on triple-negative breast cancer cells. Wound healing assay, migration test and matrigel-coated transwell assay showed that both boroleucine and dino-leucine borate inhibited the migration and invasion of breast cancer cells. Immunoblot analysis showed that both compounds down-regulated the expression of matrix metalloproteinase-2/9. In the capillary tube formation assay of human umbilical vein endothelial cells (HUVECs), dino-leucine borate showed better antiangiogenic activity than ubenimex even at a low concentration (10 μM). Moreover, compared with ubenimex, the anti-metastatic activity of dino-leucine borate in vivo was similar to or even better than that of ubenimex in the H22 pulmonary metastasis mouse model. In this paper, we found the novel APN inhibitors to markedly suppress the enzyme activity of APN and inhibit the migration and invasion of tumor cells in vitro and in vivo.

摘要： BACKGROUND With the rapid development of haploidentical hematopoietic stem cell transplantation(haplo-HSCT),primary poor graft function(PGF)has become a lifethreatening complication.Effective therapies for PGF are inconclusive.New Chinese patent medicine Pai-Neng-Da(PND)Capsule exerts dual effect in promoting hematopoiesis recovery and regulating immunity.Still,the application of PND capsule in hematopoietic stem cell transplantation,especially in the haplo-HSCT setting,has not yet been reported.AIM To evaluate the role of PND capsule in acute leukemia patients with haplo-HSCT.METHODS We retrospectively collected data of acute leukemia patients who underwent haplo-HSCT at the Affiliated People’s Hospital of Ningbo University between April 1,2015 and June 30,2020.Twenty-nine consecutive patients received oral PND capsule from the sixth day to the first month after haplo-HSCT were included in the PND group.In addition,31 patients who did not receive PND capsule during haplo-HSCT were included in the non-PND group.Subsequently,we compared the therapeutic efficacy according to the western medical evaluation indexes and Chinese medical symptom scores,and the survival between the PND group and the non-PND group,using the chi-square test,Fisher’s exact test,and the Kaplan-Meier method.RESULTS The duration of platelet engraftment was shorter in the PND group than in the non-PND group(P=0.039).The PND group received a lower frequency of red blood cells and platelet transfusions than the non-PND group(P=0.033 and P=0.035,respectively).In addition,PND capsule marginally reduced the rate of PGF(P=0.027)and relapse(P=0.043).After 33(range,4-106)months of follow-up,the 3-year relapse-free survival(P=0.046)and progression-free survival(P=0.049)were improved in the PND group than in the non-PND group.Also,the therapeutic efficacy of the PND group according to Chinese medical symptom scores was significantly better than that of the non-PND group(P=0.022).Moreover,the adverse events caused by PND capsule were mild.Nevertheless,there were no significant differences in the duration of neutrophil engraftment,the risk of infection within 100 days after haplo-HSCT,the acute graft-versus-host disease,or the 3-year overall survival between the two groups.CONCLUSION PND capsule could promote hematopoiesis reconstitution,improve the therapeutic efficacy of Chinese medical symptom scores,present anti-tumor effectiveness,and prolong the survival of acute leukemia patients with haplo-HSCT.

摘要： Computer analysis of N-(β-D-galactopyranosyl)-thiosemicarbazide compounds by in silico method revealed high probability of antibacterial (antimycobacterial), anti-tuberculosis (antituberculosic), antiviral (Influenza), antitumor (antineoplastic) 9 > Pa > 0.5 and with a low probability of cytotoxic/cytostatic (cytostatic/cytotoxic) activities. An experimental study by in vitro and in vivo methods allowed us to conclude that studied new synthetic compound N-(β-D-galactopyranosyl)-thiosemicarbazide in the studied concentrations has a pronounced bactericidal and bacteriostatic effects.

摘要： Metformin is a first-line drug in the fight against type 2 diabetes.In recent years,studies have shown that metformin has some preventive and therapeutic effects on liver cancer,but the effects of metformin on the gene expression of liver cancer cells are not fully known.This study focused on the differences in the gene expression profiles in liver cancer cells treated with or without metformin.A total of 153 differentially expressed genes(DEGs)(FC>2 and q-values<0.001)were found,including 77 upregulated genes and 76 downregulated genes.These DEGs are involved in mitogen-activated protein kinase(MAPK),nuclear factor-kappa B(NF-κB),cell adhesion molecules(CAMs),and leukocyte transendothelial migration signaling pathways.These findings reveal the effects of metformin treatment on gene expression profiles in liver cancer cells and provide new clues for unveiling the mechanism of the antitumor effects of metformin.

摘要： Evodiamine(EVO),one of the bioactive components of traditional Chinese medicine,has been widely concerned for its anti-tumor properties in recent years.In this review,the anti-tumor mechanism of EVO was reviewed from the aspects of inducing tumor cell apoptosis(internal pathway,external pathway and other pathways),inducing autophagy,inhibiting tumor stem cells,inhibiting cell proliferation and migration,inhibiting peripheral vascular proliferation,and recent research progress of EVO anti-tumor drugs.

摘要： A statin is a cholesterol-lowering agent,which inhibits HMG-CoA(3-hydroxy-3-methylglutaryl-coenzyme A)reductase and subsequently reduces the cholesterol precursor,and was first used commercially in 1987.The concept of cholesterol restriction leading to cancer cell dysfunction was proposed in 1992.The interruption of different signaling pathways has been proved in preclinical experiments to elucidate the anti-tumor mechanism of statins in pancreatic adenocarcinoma.Observational studies have shown that the clinical use of statins is beneficial in patients with pancreatic adenocarcinoma,including a chemoprevention effect,post-surgical resection follow-up and therapeutic prognosis of advanced cancer stage.Arrest of the cancer cell cycle by the combined use of gemcitabine and statin was observed in a cell line study.The effect of microbiota on the tumor microenvironment of pancreatic adenocarcinoma is a new therapeutic approach as statins can modulate the gut microbiota.Hence,further randomized trials of statins in pancreatic adenocarcinoma treatment will be warranted with application of precision medicine from microbiota-derived,cell cycle-based and signaling pathway-targeted research.

摘要： Cancer is a serious threat to human health.Fungal polysaccharide is a polar biological macromolecule with low toxicity.It has a wide range of biological activities,including immune regulation,antitumor activity,and antiviral activity.In recent years,the research results have shown that polysaccharides from fungus in traditional Chinese medicine have excellent antitumor effect in liver cancer,gastric cancer,breast cancer,colon cancer,esophageal cancer,and lung cancer.Therefore,the research and development of fungal polysaccharides are of great significance for the development of antitumor drugs in the future.
