ABSTRACT
An in vitro blood-brain barrier (BBB) model is critical for enabling rapid screening of the BBB permeability of the drugs targeting on the central nervous system. Though many models have been developed, their reproducibility and renewability remain a challenge. Furthermore, drug transport data from many of the models do not correlate well with the data for in vivo BBB drug transport. Induced-pluripotent stem cell (iPSC) technology provides reproducible cell resources for in vitro BBB modeling. Here, we generated a human in vitro BBB model by differentiating the human iPSC (hiPSC) line GM25256 into brain endothelial-type cells. The model displayed BBB characteristics including tight junction proteins (ZO-1, claudin-5, and occludin) and endothelial markers (von Willebrand factor and Ulex), as well as high trans-endothelial electrical resistance (TEER) (1560 Ω.cm ± 230 Ω.cm) and γ-GTPase activity. Co-culture with primary rat astrocytes significantly increased the TEER of the model (2970 Ω.cm to 4185 Ω.cm). RNAseq analysis confirmed the expression of key BBB-related genes in the hiPSC-derived endothelial cells in comparison with primary human brain microvascular endothelial cells, including P-glycoprotein (Pgp) and breast cancer resistant protein (BCRP). Drug transport assays for nine CNS compounds showed that the permeability of non-Pgp/BCRP and Pgp/BCRP substrates across the model was strongly correlated with rodent in situ brain perfusion data for these compounds (R = 0.982 and R = 0.9973, respectively), demonstrating the functionality of the drug transporters in the model. Thus, this model may be used to rapidly screen CNS compounds, to predict the in vivo BBB permeability of these compounds and to study the biology of the BBB.

ABSTRACT
Hypoxia is frequently observed in solid tumors and also one of the major obstacles for effective cancer therapies. Cancer cells take advantage of their ability to adapt hypoxia to initiate a special transcriptional program that renders them more aggressive biological behaviors. Hypoxia-inducible factors (HIFs) are the key factors that control hypoxia-inducible pathways by regulating the expression of a vast array of genes involved in cancer progression and treatment resistance. HIFs, mainly HIF-1 and -2, have become potential targets for developing novel cancer therapeutics. This article reviews the updated information in tumor HIF pathways, particularly recent advances in the development of HIF inhibitors. These inhibitors interfere with mRNA expression, protein synthesis, protein degradation and dimerization, DNA binding and transcriptional activity of HIF-1 and -2, or both. Despite efforts in the past two decades, no agents directly inhibiting HIFs have been approved for treating cancer patients. By analyzing results of the published reports, we put the perspectives at the end of the article. The therapeutic efficacy of HIF inhibitors may be improved if more efforts are devoted on developing agents that are able to simultaneously target HIF-1 and -2, increasing the penetrating capacity of HIF inhibitors, and selecting suitable patient subpopulations for clinical trials.

ABSTRACT
Nonspecific inflammatory response is the major cause for failure of islet grafts at the early phase of intraportal islet transplantation (IPIT). Bilirubin, a natural product of heme catabolism, has displayed anti-oxidative and anti-inflammatory activities. The present study has demonstrated that bilirubin protected islet grafts by inhibiting nonspecific inflammatory response in a syngeneic rat model of IPIT. The inflammation-induced cell injury was mimicked by exposing cultured rat insulinoma INS-1 cells to cytokines (IL-1beta, TNF-alpha and IFN-gamma) in in vitro assays. At appropriate lower concentrations, bilirubin significantly attenuated the reduced cell viability and enhanced cell apoptosis induced by cytokines, and protected the insulin secretory function of INS-1 cells. Diabetic inbred male Lewis rats induced by streptozotocin underwent IPIT at different islet equivalents (IEQs) (optimal dose of 1000, and suboptimal doses of 750 or 500), and bilirubin was administered to the recipients every 12 h, starting from one day before transplantation until 5 days after transplantation. Administration of bilirubin improved glucose control and enhanced glucose tolerance in diabetic recipients, and reduced the serum levels of inflammatory mediators including IL-1beta, TNF-alpha, soluble intercellular adhesion molecule 1, monocyte chemoattractant protein-1 and NO, and inhibited the infiltration of Kupffer cells into the islet grafts, and restored insulin-producing ability of transplanted islets.

objectlve To investigate the efficacy of continuous low-dose fluorouracil with cetuximab for antiangiogenic effect on colon carcinoma xenograft,and test its antitumor effect and toxicity.Methods Balb/c mice bearing CT-26 colon carcinoma xenograft were randomly divided into five groups,receiving low-dose metronomic(LDM)fluorouracil,maximum tolerated dose(MTD)fluorouracil,cetuximab,LDM fluorouracil with cetuximab therapy and saline respectively.Tumor growth,weight loss,peripheral white blood cell counts and survival of mice were monitoted.At the end of experiment,tumors were resected for tumor microvascular density(MVD)by immunofluorescence staining. Results Tumor growth inhibition was found in mice receiving LDM fluorouracil therapy and combined therapy,without significant body weight loss or leukopenia,and the survival of mice was remarkably prolonged,compared with mice receiving MTD fluorouracil or cetuximab therapy,and the antitumor effects of the combined therapy was stronger than that of the fluorouracil LDM therapy.LDM treatment and combine treatment led to statistically significant(P＜0.05)55%and 71%reduction in tumor growth,as well as 73%and 77% reduction in tumor microvessel density compared with the control respectively.Additonally,tunnel staining shows no significant difference between these treatment groups. Conclusion Continuous low-dose regimen of fluorouracil with cetuximab can significantly increase the therapeutic activity with decreased toxicity and prolonged animal survival bearing implanted colon cancer.
ABSTRACT
Vasostatin, a 180-amino acid fragment from the N-terminal domain of calreticulin, is a potent endogenous angiogenesis inhibitor, which can inhibit the growth of many kinds of experimental tumor. But a recent report that vasostatin can enhance the malignant behavior of neuroendocrine tumor reminds us to be cautious to develop it as an anti-tumor medicine. VAS cDNA was cloned into pAAV-2 expression vector; recombinant virus rAAV-VAS was generated by a three plasmids, helper free packaging method. MS1 mouse pancreatic endothelial cell and human colon tumor HCT-116 cell were infected with rAAV-VAS. Transgene expression was analyzed by Western blotting analysis; cell proliferation was determined by MTT assay. The therapeutic potential of rAAV-VAS was evaluated in subcutaneous HCT-116 xenograft mouse model. rAAV-VAS inhibited the proliferation of MS1 but not HCT-116 cell. HCT-116 cell infected with rAAV-VAS secreted VAS protein into the supernatant effectively. The intratumoral delivery of rAAV-VAS inhibited the xenograft growth and microvessel density in tumors significantly. Our results show the effectiveness of rAAV-VAS as an angiogenesis inhibitor in suppressing tumor growth, validating the application of rAAV-VAS gene therapy in treatment against colon cancer.
