Abstract
In-stent restenosis caused by tumor ingrowth is a major problem for patients undergoing stent placement because conventional stents often lack sustainable antitumor capabilities. The aim of this work is to develop a silk fibroin (SF)-based nanofibrous membrane that is loaded with combined-therapy drugs by using electrospinning technologies, which is further coated on a polydioxanone (PDO) stent and used for the treatment of colorectal cancer (CRC). In order to improve treatment effectiveness, a combination of therapeutic drugs, i.e., curcumin (CUR) and 5-fluorouracil (5-FU), is dissolved into SF solution and then eletrospun onto the surface of the PDO stent. The morphology, secondary structure, and in vitro drug release profiles of the membranes are characterized. The antitumor efficacy is assessed in vitro and in vivo using a human CRC cell line and normal cells, and tumor-bearing nude mice. In vitro and in vivo studies on the nanofibrous memembrane-coating demonstrate improved antitumor effects for the CUR/5-FU dual drug system which can be attributed to cell cycle arrest in the S phase in association with induced apoptosis in tumor cells by blocking signal transducer and activator of transcription3 (Stat3) and nuclear factor kappa beta (NF-kB) signaling pathways, suggesting potential in the treatment of CRC in the future.

Abstract
Objective TMEM119 is a member of transmembrane proteins family, which is abnormally expressed in human cancers and associated with tumorigenesis. In this study, we focused on the expression of TMEM119 and its role in cell invasion and migration in gastric cancer. Methods Real-time polymerase chain reaction, Western blotting, and immunohistochemistry were performed to examine the expression of TMEM119 in gastric cancer tissues and cell lines. After transfection with TMEM119 siRNA or recombined TMEM119-expressing vector, the invasion and migration ability of MKN45 and SGC-7901 cells was measured by transwell assay. The expression of TMEM119, p-STAT3, STAT3, VEGF, MMP2, and MMP9 proteins in SGC-7901 and MKN45 cells treated with TMEM119 siRNA, TMEM119-expressing vector, or AG490 was measured by Western blotting. Results We found that higher TMEM119 expression was found in gastric cancer tissues and cell lines and was associated with lower survival rate. TMEM119 knockdown inhibited SGC-7901 cell invasion and migration, along with the expression of p-STAT3, VEGF, MMP2, and MMP9. TMEM119 overexpression promoted MKN45 cell invasion and migration, along with the expression of p-STAT3, VEGF, MMP2, and MMP9. Additionally, AG490 treatment significantly corrected TMEM119-induced MKN45 cell migration and invasion and expression of p-STAT3, VEGF, MMP9, and MMP2 proteins. Conclusion The results indicated that TMEM119 promotes gastric cancer cell migration and invasion through activation of STAT3 signaling pathway, and TMEM119 may therefore act as a novel therapeutic target for gastric cancer.

Abstract
Background: Polypharmacology is emerging as the next paradigm in drug discovery. However, considerable challenges still exist for polypharmacology modeling. In this study, we developed a rational design to identify highly potential targets (HPTs) for polypharmacological drugs, such as berberine. Methods and Results: All the proven co-crystal structures locate berberine in the active cavities of a redundancy of aromatic, aliphatic, and acidic residues. The side chains from residues provide hydrophobic and electronic interactions to aid in neutralization for the positive charge of berberine. Accordingly, we generated multi-target binding motifs (MBM) for berberine, and established a new mathematical model to identify HPTs based on MBM. Remarkably, the berberine MBM was embodied in 13 HPTs, including beta-secretase 1 (BACE1) and amyloid-β1-42 (Aβ1-42). Further study indicated that berberine acted as a high-affinity BACE1 inhibitor and prevented Aβ1-42 aggregation to delay the pathological process of Alzheimer's disease. Conclusion: Here, we proposed a MBM-based drug-target space model to analyze the underlying mechanism of multi-target drugs against polypharmacological profiles, and demonstrated the role of berberine in Alzheimer's disease. This approach can be useful in derivation of rules, which will illuminate our understanding of drug action in diseases.

JOURNAL OF ETHNOPHARMACOLOGY 2017; 208:253-263.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pharbitis Nil (PN) is used as a main component of the existing drug, DA-9701, which was developed to treat functional dyspepsia (FD) in Korea. PN extracts isolated from its seeds have been reported to have anticancer effects. AIM OF THE STUDY The purpose of this study was to investigate the underlying mechanism of the chemotherapeutic effects of PN in lung cancer cells. MATERIALS AND METHODS We performed MTT assays, colony formation assays, flow cytometry assays, Western blot analysis, reverse transcription-polymerase chain reaction (RT-PCR), immunofluorescence analysis, and cell counting assays to study the molecular mechanism of chemotherapeutic effects of PN in lung cancer cells. RESULTS Our results indicate that PN induced autophagy as well as apoptosis. PN inhibited cell proliferation and survival by inducing apoptosis in several lung cancer cell lines. PN-treated cells also exhibited induction of autophagy, as evidenced by increased protein expression levels and punctuate patterns of LC3 II. Moreover, activation of extracellular signal-regulated kinases 1 and 2 (ERK1/2), which plays an important role in autophagy activation, was shown to be related with PN-induced autophagy. Interestingly, pharmacological blockade of autophagy activation with wortmannin and inhibition of ERK1/2 phosphorylation by U0126 markedly enhanced PN-induced apoptosis and reduced cell viability, suggesting that autophagy induced by PN may have a cytoprotective effect by suppressing apoptosis. PN- induced apoptosis was regulated by signal transducer and activator of transcription 3 (STAT3) deactivation. Moreover, decrease of STAT3 activation in PN-treated cells was associated with reduced survivin expression, further demonstrating that PN-induced apoptosis was regulated by STAT3 deactivation. CONCLUSION We believe that PN, which is already proven to treat human patients with FD, might be a potential anticancer drug for human lung cancer. In addition, our data suggest that the combination of PN treatment with an autophagy inhibitor or traditional anticancer agents may be an effective anticancer therapy.
