Progress in targeting therapy of cancer metastasis by CCL21/CCR7 axis / 生物工程学报

Metastasis is the leading cause of mortality for cancer patients, and lymphatic metastasis is one of the main ways of tumor metastasis. The role of CCL21 and its receptor CCR7 in lymphatic metastasis has been increasingly concerned in recent years. CCR7 is mainly expressed by both dendritic cells and T cells for immune responses. CCL21, the chemokine ligand for CCR7, secreted from lymphatic endothelial cells binds CCR7 and recruits immune cells toward lymphatic vessels and lymphatic nodes. CCR7 expressed tumor cells can also metastasize to lymphatic system by the similar way as immune cells. Targeting CCL21/CCR7 axis to inhibit lymphatic metastasis but remain potent anti-tumor immune response has increasingly become a spot light of tumor immunotherapy. In this review, we summarize the role of CCL21/CCR7 axis in lymphatic metastasis, as well as preclinical trials and clinical trials in targeting CCL21/CCR7 axis for tumor metastasis therapy, hoping to accelerate the progress on tumor metastasis therapy by targeting CCL21/CCR7 axis.

Protective effects of CMP on 5-Fu-induced intestinal mucositis of mice / 中国药理学通报

Aim To evaluate the mucosal-protective effects of carboxymethylpachyman( CMP) on Fluorou-racil(5-Fu)-induced mice intestinal mucositis and ex-plore its mechanisms. Methods ICR mice were as-signed randomly to four groups:normal group( n=8;re-ceiving pure water orally for 14 d) ,CMP group( n=8;200 mg·kg-1 CMP for 14 d orally),5-Fu group(n=8;25 mg·kg-1 5-Fu for 7 d,intraperitoneally( i. p. ) , and CMP+5-Fu group( n=8;200 mg·kg-1 CMP for 14 d orally and 25 mg·kg-1 5-Fu for 7 d,i. p. ). At day 14the mice were sacrificed. The intestinal propel-ling rate and the colon length were measured. ROS, GSH and IL-1βcontents,and CAT,GSH-Px activities in homogenate supernatant of PPs were measured by kits for observing the effects of CMP on mice lipid peroxida-tion and intestinal mucosal inflammatory induced by 5-Fu. Colon tissues were used for hematoxylin and eosin ( HE ) staining for the determination of the effect of CMP on mice colon histopathology, immunohistochem-istry for the protein levels of NF-κB and p-p38 . Results CMP significantly extended colon lengths,accelerate the intestinal propelling rates, reduced colonic mucosa epithelium goblet cell loss, inflammatory cells infiltra-tion,and crypt depth shallow induced by 5-Fu. CMP obviously reduced ROS and IL-1β contents, and pre-vented reductions in homogenate supernatant of PPs GSH content, CATand GSH-Px activities by 5-Fu ad-ministration,and also reduced the expression of NF-κB and p-p38 in colon tissues. However, CMP alone had no effect on the colon of normal mice. Conclusion The current study demonstrates that CMP may have sig-nificant protective effects against 5-Fu-induced intesti-nal mucositis. Its mechanism may be related to enhan-cing the antioxidant activity,anti-inflammatory and an-ti-apoptotic effects.

Expression of serum miR-31 in colorectal cancer patients and its effect on cell proliferation and ;apoptosis / 中国癌症杂志

Background and purpose:miRNA plays important roles in tumorigenesis. It has been reported that many kinds of serum miRNA serve as markers for tumor diagnosis and screening. This study aimed to detect the expression of serum miRNA-31 (miR-31) in colorectal cancer patients and to explore the effect of miR-31 on cell proliferation, apoptosis and cell cycle distribution. Methods: The expressions of miR-31 in 40 cases of colorectal cancer serum and 35 cases of the healthy control were examined by real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR). The correlation between miR-31 expression and clinicopathological features of colorectal cancer (including age, gender, depth of inifltration, lymph node metastasis, clinical stage) were further analyzed. The miR-31 mimics, inhibitor and miR-control (negative control) were transfected into HCT116 cells. The effect of miR-31 on cell proliferation was evaluated by CCK-8 method. Flow cytometry was used to examine the change of cell apoptosis and cell cycle. Results:Relative expression of serum miR-31 was signiifcantly increased in cancer patients compared with healthy controls (P<0.01). Expression of serum miR-31 was higher in poorly differentiated carcinoma than that in well or moderately differentiated carcinoma (P<0.05). No correlation was found between serum miR-31 expression and other clinicopathological variables. CCK-8 assay showed that after transfection with miR-31 mimics, the cell proliferation was increased, compared with miR-31 inhibitor and negative control group. Meantime, the apoptotic cell number was signiifcantly decreased, particularly in late apoptosis. The cell number of G1 stage was remarkably increased in miR-31 inhibitor group, compared with miR-31mimics and negative control group. Conclusion:The expression of serum miR-31 is higher in colorectal cancer. miR-31 can promote cell proliferation and inhibit the apoptosis of HCT116 cells. It might be a potential biomarker for colorectal cancer.

Expressions of miR-139-5p and TGIF1 in colorectal cancer and their intercorrelation / 肿瘤

Objective: To investigate the expression levels of microRNA-139-5p (miR-139-5p) and transforming growth factor β-induced factor 1 (TGIF1) mRNAs in human colorectal cancer (CRC) tissues, and explore their intercorrelation and the role in progression and prognosis of CRC. Methods: The expression levels of miR-139-5p and TGIF1 mRNA in 44 CRC tissue specimens and the corresponding para-cancerous tissues were detected by real-time fluorescent quantitative-PCR. The target gene of miR-139-5p was predicted by Target Scan software. The colonic cancer HCT116 cells were transfected with pre-miR-139-5p, then the intercorrelation between miR-139-5p and TGIF1 was confirmed by real-time fluorescent quantitative-PCR and Dual-Luciferase Reporter Assay. The relationships of TGIF1 mRNA expression with clinicopathological features and prognosis of patients with CRC were analyzed. Results: The expression level of miR-139-5p in CRC tissues was significantly lower than that in the corresponding para-cancerous tissues (P < 0.001), while the expression level of TGIF1 mRNA in CRC tissues was significantly higher than that in the corresponding para-cancerous tissues (P < 0.001). There was a negative correlation between the expression levels of miR-139-5p and TGIF1 mRNA (r = -0.708, P < 0.001). The expression level of miR-139-5p in HCT116 cells after transfection with pre-miR-139-5p was significantly up-regulated (P < 0.001), while the expression level of TGIF1 mRNA was down-regulated (P = 0.09). There was an interaction between miR-139-5p and its target gene TGIF1. The expression of TGIF1 mRNA was correlated with the depth of tumor invasion, but not correlated with the survival. Conclusion: miR-139-5p is down-regulated in human CRC tissues, while TGIF1 mRNA is obviously overexpressed. miR-139-5p may be involved in the development of colorectal cancer through down-regulating the expression of TGIF1.

The anti-tumor activity and molecular mechanisms of an Aurora kinase inhibitor ZLJ213 in suppressing colon cancer growth / 药学学报

The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.

Effects of Nuciferine on Mice with Hyperlipidemia and Its Mechanisms / 医药导报

Objective To investigate the effects of nuciferine on hyperlipidemia in mice and to clarify the molecular mechanism. Methods Mice were divided into three groups according to the diet: normal control group ( n=10 ) , model control group (n=10), and the intervention group (n=10). The normal control group was treated with common diet (ANI-76A feed:12. 4% fat, 68. 8% carbohydrate, 18. 8% protein). The model control group was induced with high fat diet (37. 1% fat, 42. 4% carbohydrate, 20. 5% protein). The intervention group was supplemented with 0. 5% nuciferine based on high fat diet. The mice were allowed free access to food and water for a total of 10 weeks. Several indices were analyzed in the 3 groups, including the body weight, serum lipid, lipid metabolism key enzyme, oxidative stress and metabolic pathway. Results Our results suggested that the high-fat diet-induced animal models developed obesity and dyslipidemia (P0.05).Theactivityofhepaticlipidmetabolismkeyenzymes[(4.15±1.26) U·mL-1vs.(9.01±1.34) U·mL-1] andthe activity of hepatic lipase and lipoprotein lipase[(8.12±3.07) U·mL-1 vs.(13.48±3.75) U·mL-1] were elevated.Oxidative stress was also affected by nuciferine (P<0. 05). Mechanism study suggested that lipid synthesis genes (like SREBP-1c, FAS, SCD-1 and PPAR gamma mRNA) were up-regulated by high fat diet (P<0. 05), and the lipid oxidation metabolism genes, PPARαand CPT-1a mRNA, were down-regulated (P<0. 05), while the intervention group treatment reversed these changes (P<0. 05). Conclusion Nuciferine can improve hyperlipidemia, which might be related to the regulation of enzyme activity, oxidative stress and the changes of lipid synthesis and oxidative metabolism.
