Abstract
The study aimed to investigate antioxidant activities of two different thermally treated sesame (Sesamum indicum L.) leaf ethanol extract, steamed sesame leaf extract (SSLE) and roasted sesame leaf extract (RSLE), and their inhibitory effects on uncontrolled growth and increased metastatic properties in human colon cancer cell lines. Both SSLE and RSLE contained pedaliin as the major polyphenol and its aglycon, pedalitin, as a minor component and exhibited radical scavenging activities and ferric reducing antioxidant power. SSLE and RSLE decreased growth of HT29 and HCT116 colon cancer cells, which was attributed to the induction of apoptosis and cell cycle arrest at either G2/M (by SSLE in HCT116) or S phase (by RSLE in HCT116). Furthermore, SSLE and RSLE inhibited migration and adhesion in both cell lines. These results indicate that thermally treated sesame leaves retained pedaliin content and exhibited antioxidant activities and inhibitory activities against the growth and metastatic properties of colon cancer cells.

Abstract
OBJECTIVE Lipopolysaccharide (LPS) is a major cell wall component of gram-negative bacteria. Colon bacteria contribute to LPS which promotes colon cancer metastasis. The objective of this study was to survey the effect of LPS on cell viability and gene expression of 55 molecular targets in human colon cancer cells. RESULTS LPS did not affect the viability of COLO 225 cells under the culture conditions but affected the expression of a number of genes important in inflammatory responses and cancer development. LPS increased TTP family, GLUT family and DGAT1 mRNA levels but decreased DGAT2a and DGAT2b expression in the human colon cancer cells. LPS also increased COX2, CXCL1, ELK1, ICAM1, TNFSF10 and ZFAND5 but decreased BCL2L1, CYP19A1 and E2F1 mRNA levels in the colon cancer cells. These data suggest that LPS has profound effects on gene expression in human colon cancer cells.

Abstract
A lectin (designated as ARL) was purified first time from the Asparagus racemosus root with the molecular weight of 14.0 kDa containing about 4.8% carbohydrate. ARL showed hemagglutination activity in both mice and human erythrocytes that were inhibited by three complex sugars among the 26 sugars tested. ARL was thermostable that mostly preserved activity at its optimum pH 8.0. Around 48% and 52.5% human colorectal cancer (HCT-116) cells growth was inhibited by 160 μg/ml of ARL and 256 μg/ml of previously purified Geodorum densiflorum rhizome lectin (GDL). Induction of apoptosis in HCT-116 cells was confirmed by Hoechst 33342 staining, caspase inhibitors, but ROS generation was only observed for ARL. The expression level of BAX and p53 genes increased with a decrease of PARP gene expression for both lectins. The expression of FAS and FADD were increased with the decrease of WNT after treatment with GDL. ARL inhibited 68% and 26% of Ehrlich ascites carcinoma cell growth in vivo in mice after treating with 3.0 and 1.5 mg/kg/day doses for five consecutive days. ARL increased the expression level of NFκB and arrested S cell cycle phase in EAC cells, in contrast, G2/M phase was arrested by ARL and GDL in HCT-116.

Abstract
Glucose, a major energy source in cellular metabolism, has a significant role in cell growth. The increase in glucose uptake is a distinguishing hallmark in cancer cells. A key step in glucose utilization is the transport of glucose to the cancer cells for supplying their additional energy. The glucose transporter (or GLUT) family is a membrane protein which facilitates the uptake of glucose in most cancer cell types. Given the increased glucose level in cancer cells and the regulatory role of GLUTs in glucose uptake, it is required to combine both experimental and theoretical studies to develop new methods to monitor cell proliferation. Herein, for the first time, a new strategy was proposed to evaluate the cell proliferation of HT-29 based on glucose consumption in the presence of resveratrol (RSV) as an anticancer agent. A hybrid nanocomposite of carbon nanofibers and nitrogen-doped graphene quantum dots was used to design an enzymatic sensor for the selective and sensitive determination of glucose in cancer cells. The results obtained from the voltammetric technique were compared with the conventional colorimetric assay. A good correlation was observed between the proliferation rate and glucose utilization by cancer cells. As it was observed, RSV induces a decrease in glucose consumption, indicating lower glucose uptake efficiency for HT-29 cells. Molecular docking studies reveal that RSV can block the interaction of glucose with the GLUT family. This is one of the possible mechanisms for the decrease of glucose level followed by the reduction of cell proliferation in the presence of RSV. Compared with traditional methods, in vitro electrochemical techniques benefit from simple, nontoxic, sensitive and low-cost detection assays and hence serve as a novel tool to pursue the growth inhibition of cancer cell in response to anti-cancer agents.

Abstract
BACKGROUND Colorectal cancer (CRC) is a major clinical challenge, and the gut microbiome plays important roles in the occurrence and metastasis of CRC. Lactobacillus and their metabolites are thought to be able to suppress the growth of CRC cells. However, the antimetastatic mechanism of Lactobacillus or their metabolites toward CRC cells is not clear. Therefore, the aim of this study was to assess the inhibitory mechanism of cell-free supernatants (CFSs) of L. rhamnosus GG, L. casei M3, and L. plantarum YYC-3 on metastasis of CRC cells. RESULTS YYC-3 CFS showed the highest inhibitory effect on CRC cell growth, invasion and migration, and inhibited MMP2, MMP9, and VEGFA gene and protein expression, and protein secretion. Furthermore, it suppressed the activities of MMPs by gelatin zymography. Moreover, the effective compounds in these CFSs were analyzed by Q Exactive Focus liquid chromatography-mass spectrometry. CONCLUSIONS Our results showed that metabolite secretions of YYC-3 may inhibited cell metastasis by downregulating the VEGF/MMPs signaling pathway. These data suggest that treatment of CRC cells with metabolites from L. plantarum YYC-3 may reduce colon cancer metastasis.

Abstract
BACKGROUND The integrin β6 gene, which is expressed in epithelial cancer, plays a pivotal role in various aspects of cancer progression. The present research for integrin β6 regulation mainly focuses on the post-transcription and translation related regulation mechanism and its role in tumorigenesis. The mechanisms of how the integrin β6 gene is regulated transcriptionally, and the promoter and transcription factors responsible for basic transcription of integrin β6 gene remain unknown.
AIM To clone and characterize the integrin β6 promoter.
METHODS Software analysis was used to predict the region of integrin β6 promoter. Luciferase reporter plasmids, which contained the integrin β6 promoter, were constructed. Element deletion analysis was performed to identify the location of core promoter and binding sites for transcription factors.
RESULTS The regulatory elements for the transcription of the integrin β6 gene were located between -286 and -85 and contained binding sites for transcription factors such as STAT3 and Ets-1.
CONCLUSION For the first time, we found the region of β6 core promoter and demonstrated the binding sites for transcription factors such as Ets-1 and STAT3, which are important for integrin β6 promoter transcription activity. These findings are important for investigating the mechanism of integrin β6 activation in cancer progression.

Abstract
Cordyceps sinensis is thought to have anti-cancer effects, but its mechanisms remain elusive. In this study, we aimed to investigate the anti-cancer effect of Cordyceps sinensis polysaccharide (CSP) on human colon cancer cell line (HCT116) and its mechanism. Results indicated that CSP significantly inhibited the proliferation of HCT116 cells, increased autophagy and apoptosis, while blocked autophagy flux and lysosome formation. Further experiments showed that CSP decreased the expression of PI3K and phosphorylation level of AKT and mTOR, increased the expression of AMPKa and phosphorylation level of ULK1. In addition, repression of CSP-induced autophagy by bafilomycin (autophagy inhibitor) enhanced apoptosis and cell death of HCT116 cells. Hence, our findings suggested that CSP inhibited the proliferation of HCT116 cells by inducing apoptosis and autophagy flux blockage, which might be achieved through PI3K-AKT-mTOR and AMPK-mTOR-ULK1 signaling. CSP may be a potential therapeutic agent for colon cancer.

Abstract
In the study, folic acid doped Prussian blue nanoparticles (FA-PB NPs) for theranostic applications were synthesized for the first time. Folic acid was chosen for maintaining nanoparticle stability and also to increase its binding affinity especially for cancer cells. Multifunctional PB NPs were fabricated by one route co-precipitation method to synthesize biocompatible NPs without any further process. Then, FA was doped on the surface of PB NPs. The characterization studies demonstrated that the FA-PB NPs modified sensor surface had large surface area with biocompatible and hydrophilic properties where cancer cells can easily bind. The FA-PB NPs were used for the modification of pencil graphite electrode (PGE) for electrochemical detection of colon cancer cells (DLD-1). Electrochemical impedimetric diagnosis was based on the specific interaction between FA groups on the nanoparticles and FA receptors overexpressed on cancer cells. The voltammetric and impedimetric results showed that the FA-PB NPs based electrode had good sensing performance for the immobilized DLD-1 cells.

Abstract
Metformin, an oral medicine broadly used for the treatment of type 2 diabetes, has been found to significantly improve tumor incidence and survival in large-scale clinical analysis. In recent years, the antitumor effect and mechanism of metformin have received much attention. Myeloid-derived suppressor cells (MDSCs), a major immunosuppressive cell type that accumulates in tumor-bearing hosts, can inhibit T cells and promote tumor immune escape. The mechanism by which metformin exerts its anti-tumor effect by regulating MDSCs remains unclear. Here, we found that metformin could inhibit the accumulation and suppressive capacity of G-MDSCs, delay tumor progression and elicit Th1 and CTL responses in murine colon cancer CT-26 cell-transplanted mice. In additionally, metformin could enhance the phosphorylation of AMPK, reduce STAT3 phosphorylation levels, and down-regulate the inhibitory function of G-MDSCs in vitro. These results suggest that metformin may be a potential clinical benefit for antitumor immunotherapy in tumor-bearing mice.

Abstract
Fluorescence of DNA-templated copper nanoparticles (DNA-CuNPs) is not stable over time which limits applications in cellular imaging. This is due to the presence of oxygen during synthesis which oxidizes Cu(0) to Cu(II) and also produces the free hydroxyl radical. The authors have prepared DNA-CuNPs with enhanced temporal stability of fluorescence by optimizing the reaction conditions so as to minimize the deleterious effects of oxygen. The operational lifetime of DNA-CuNPs was increased from 25 min to 200 min. Fluorescence spectra of DNA-CuNPs in optimized condition show an emission peak at 650 nm when excited at 340 nm. DNA-CuNPs synthesized in this manner were used for cell imaging. As a proof of concept, the nucleus of a human colon cell line (HCT116) was stained. The method does not involve any chemicals other that copper sulfate and ascorbate. This new approach for generating DNA-CuNPs improves imaging of biological processes and provides a basis for developing other types of DNA-templated nanomaterials. Graphical abstract Schematic presentation of the formation of fluorescent DNA-templated copper nanoparticles (DNA-CuNPs). A large amount of ascorbate provides long operational lifetime for cellular imaging under the condition exposed to oxygen. *Asc- and **DHA stand for ascorbate and dehydroascorbic acid.

Abstract
Previous researches have reported that microcystin-LR (MC-LR) contributes to the progression of multiple types of carcinomas including colon cancer; however, the underlying molecular mechanisms remain unclear and require in-depth investigation. Here, the colon cell line DLD-1 was arranged for the analysis by the microRNA microarray which was associated with the cancer metastasis after MC-LR exposure. 31 human microRNAs were differentially expressed, including miR-221, which targeted 3'-UTR of PTEN mRNA and PTEN level was down-regulated by MC-LR treatment. Besides, MC-LR also induced the phosphorylation of STAT3, which can be reversed by adding miR-221 inhibitor and PTEN expression plasmid. Furthermore, miR-221 inhibitor, STAT3 siRNA and PTEN expression plasmid could reverse the effects of MC-LR induced migration with the accumulation of β-catenin in nuclei. In conclusion, our study suggested that MC-LR promoted the progression of colon carcinoma, at least in part, by regulating the expression miR-221, PTEN and STAT3 phosphorylation, which offers a novel perspective to understand the connection between MC-LR and colon cancer.

Abstract
BACKGROUND Royal jelly (RJ), the exclusive food for the larva of queen honeybee, is regarded as the novel supplement to promote human health. The function of RJ may be attributed to its major and unique fatty acid, 10-hydroxy-2-decenoic acid (10-HDA). The current study investigated the anti-inflammory function of 10-HDA on human colon cancer cells, WiDr, as well as its effect on the growth of pathogenic bacterium. METHODS The pro-inflammatory cytokines, receptor antagonist cytokine (IL-1ra) and nuclear factor-kappa B (NF-κB) in WiDr cells was analyzed by Enzyme-linked immunosorbent assay (ELISA) or western blot. The growth inhibition of 10-HDA on bacterium was evaluated by determination of minimal inhibitory concentrations (MIC) and minimal bactericide concentrations (MBC). RESULTS The production of pro-inflammatory cytokines, Interleukin (IL)-8, IL-1β and tumor necrosis factor-alpha (TNF-α) in WiDr cells was modulated by 10-HDA. IL-8 were dramatically declined by 10-HDA at 3 mM, while IL-1β and TNF-α were significantly decreased. 10-HDA increased IL-1ra in a dose manner. NF-κB pathway is primarily in response to prototypical pro-inflammatory cytokines, and NF-κB was reduced after 10-HDA treatment. 10-HDA acted as potent bactericide against animal- or human-specific pathogens, including Staphylococcus aureus, Streptococcus alactolyticus, Staphylococcus intermedius B, Staphylococcus xylosus, Salmonella cholearasuis, Vibro parahaemolyticus and Escherichia coli (hemolytic). CONCLUSIONS The current study showed that in vitro 10-HDA from RJ exhibited anti-inflammatory activity in WiDr cells, as well as anti-bacterial activity against animal pathogens. 10-HDA showed its potential as anti-imflammtory agent and bactericide to benefit human gastrointestinal tract.

Abstract
Background Genistein has been known to inhibit proliferation and induce apoptosis in several kinds of cancer cells. While knowledge of genistein in regulating epithelial mesenchymal transition (EMT) of colon cancer cells is unknown. Methods To investigate the effects and mechanisms of genistein on EMT of colon cancer cells, HT-29 cells were used and treated by genistein and TNF-α in this paper. EMT was determined by cell invasion assays using a transwell chamber and the expression changes of EMT-related markers were confirmed by RT–PCR, Western blotting, and immunofluorescence staining. Results Genistein inhibited cell migration at 200 μmol/L. Genistein reversed the EMT of colon cancer cells by upregulation of E-cadherin and downregulation of N-cadherin, accompanied by the suppression of EMT related makers, such as Snail2/slug, ZEB1, ZEB2, FOXC1, FOXC2 and TWIST1. Moreover, genistein can inhibit the expression of notch-1, p-NF-κB and NF-κB, while promote the expression of Bax/Bcl-2 and caspase-3 in HT-29 cells. Conclusion The present study demonstrated that genistein suppressed the migration of colon cancer cells by reversal the EMT via suppressing the Notch1/NF-κB/slug/E-cadherin pathway. Genistein may be developed as a potential antimetastasis agent to colon cancer.

Abstract
Evidence demonstrate that p53 mutations and microRNAs (miRs) are important components of 5-FU resistance in colorectal cancer (CRC). miR-338-3p has been reported associated with cancer prognosis. However whether or not it influences chemotherapy sensitivity and the underlying mechanisms have not been elucidated. Here, three types of human colon cancer cell lines, HT29 (mutant p53), HCT116 (wild-type p53), and HCT116 p53-/- (deficient p53), were treated with 5-FU. We showed that expression of miR-338-3p was correlated with apoptosis and 5-FU resistance in colon cancer cells. Ectopic expression of miR-338-3p conferred resistance to 5-FU in HCT116 cells. Further experiments indicated that miR-338-3p mediated 5-FU resistance through down-regulation of mTOR expression. Moreover, inhibition of miR-338-3p in HT29 and HCT116 p53-/- cells increased their sensitivity to 5-FU treatment. Furthermore, we detected autophagy changes in our experiment because mTOR was known prominently regulating autophagy and the competition between autophagy and apoptosis in response to 5-FU was a mechanism influencing 5-FU sensitivity. Our results reveal a critical and novel role of miR-338-3p in the correlation of 5-FU resistance with p53 status. Moreover, the miR-338-3p inhibitor has the potential to overcome 5-FU resistance in p53 mutant colon cancer cells.

Abstract
In present investigation, initially curcumin was complexed with 2-HP-β-CD (curcumin-2-HP-β-CD-complex) in 1:1 ratio and later amalgamated with chitosan microspheres (curcumin-2-HP-β-CD-CMs) for selective delivery in colon only through oral route of administration. Various analytical, spectral and in-silico docking techniques revealed that the curcumin was deeply inserted in the 2-HP-β-CD cavity with apparent stability constant of 3.35×10-3M. Furthermore, the mean particle size of 6.8±2.6μm and +39.2±4.1mV surface charge of curcumin-2-HP-β-CD-complex-CMs in addition to encapsulation efficiency of about 79.8±6.3% exhibited that the tailored microspheres were optimum for colon delivery of curcumin. This was also demonstrated in dissolution testing and standard cell proliferation assay in which curcumin-2-HP-β-CD-complex-CMs exhibited maximum release in simulated colonic fluid (SCF, pH ∼7.0-8.0, almond emulsion-β-glucosidase) with improved therapeutic index in HT-29 cells. Consistently, curcumin-2-HP-β-CD-complex-CMs successively enhanced the colonic bio-distribution of curcumin by ∼8.36 folds as compared to curcumin suspension in preclinical pharmacokinetic studies. In conclusion, curcumin-2-HP-β-CD-complex-CMs warrant further in vivo tumor regression study to establish its therapeutic efficacy in experimental colon cancer.

Abstract
AIM: To investigate the effect of sodium orthovanadate (SoV), an inhibitor of phosphatase of regeneration liver-3 (PRL-3), on the migration of Colo-320 colon cancer cells.
METHODS: The expression levels of PRL-3 protein in seven colorectal cancer cell lines were examined by Western blot to screen the line with the highest expression of PRL-3 protein. The screened cell line was employed in subsequent drug intervention experiments. A scratch wound assay was performed to examine the effect of SoV (at a dose of 0.5 μmol/L) on the migration of Colo-320 cells. The migration distance of cells was determined under an inverted microscope. The expression of PRL-3 mRNA in cells treated with SoV was detected by in situ hybridization.
RESULTS: Western blot analysis indicated that the colon cancer cell line Colo-320 had the highest expression level of PRL-3. The scratch wound assay showed that the migration distance of Colo-320 cells treated with SoV for 48 hours was significantly lower than that of control cells. The migration rate of SoV-treated cells was also significantly lower than that of control cells (2.84 ± 6.78 μm/h vs 39.12 ± 10.11 μm/h, P < 0.00001). In situ hybridization analysis showed that PRL-3 mRNA was highly expressed in control cells but not in SoV-treated cells.
CONCLUSION: SoV can effectively inhibit the migration of Colo-320 cells perhaps through downregulation of PRL-3 mRNA expression and suppression of PRL-3 catalytic activity.
