Abstract Background: This study was aimed to investigate the effect of Scutellarin on apoptosis of human colorectal cancer SW480 cells and azoxymethane (AOM)/dextran sulfate sodium (DSS) mouse, and clarify its mechanism. Methods: 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di- phenytetrazoliumromide (MTT) and cell migration assay were performed to detect the viability and proliferation of SW480 cells that treated with different concentrations of Scutellarin. Hoechst33342 Staining to determine apoptosis, detecting Caspase-3 and Caspase-9 activities after administration of different concentrations of Scutellarin. AOM/DSS mouse were administrated with Scutellarin; immunohistochemistry and western blot was employed to detect the effect on the expression of BCL2-Associated X (Bax) and B-cell lymphoma-2 (Bcl-2) proteins, and the message Ribonucleic Acid (mRNA) levels of Bax, Bcl-2, Caspase-3and Caspase-9 were assessed with quantitative reverse transcription polymerase chain reaction (qRT-PCR). The data was analyzed by one-way analysis of variance (ANOVA) with SPSS19.0 software, expressed as mean ± standard deviation (x ± s). Results: Scutellarin could inhibit the proliferation of SW480 cells after treatment with different concentrations of Scutellarin, while the chromatin condensation and nucleus showed more intense blue fluorescence. Moreover, Scutellarin could significantly increase the activities of Caspase-3 and Caspase-9 as well as different concentrations of Scutellarin could significantly down-regulate the expression of apoptosis related protein Bcl-2 and up-regulate the expression of Bax protein. When compared with the solvent control group, the relative expression levels of the related gene Bcl-2 were down-regulated by different concentrations of Scutellarin, while the Bax, Caspase-3 and Caspase-9 genes were up-regulated. Conclusion: Scutellarin can inhibit the in vitro activity of colon cancer SW480 cells, promote Bax expression, inhibit Bcl-2 expression, and up-regulate the activities of apoptotic enzymes Caspase-3 and Caspase-9 to induce apoptosis in vivo and in vitro, suggesting that it has a certain therapeutic effect on colon cancer.

Selenium compounds have been implicated as anticancer agents; however, the mechanism of their inhibitory action against cancer development has not been extensively investigated. The constitutive activation of the Wnt/β-catenin pathway is a central event in colorectal carcinogenesis. In this pathway, the excessive cell proliferation is initiated by the generation of β-catenin followed by overexpression of proto-oncogenes such as c-Myc. It is believed that under physiological conditions the level of c-Myc is efficiently controlled by accessibility of β-catenin protein through the process of phosphorylation by glycogen synthase kinase 3β (GSK-3β). Here, we determined whether selenomethionine (SeMet) can inhibit cell growth and affect the Wnt/β-catenin pathway in HT-29 human colorectal cancer cells in vitro. The effective cytotoxic doses of SeMet have been selected after 48 h of incubation of this compound with colorectal cancer HT-29 cell line. The MTT assay was used to assess cell viability and the protein and mRNA levels of β-catenin and c-Myc were determined by Western blotting and qPCR, respectively. The SeMet potently inhibited growth of HT-29 cells, significantly decreased the β-catenin protein and mRNA concentration, down-regulated the c-Myc gene expression and up-regulated pro-apoptotic Bax protein expression. Moreover, SeMet increased the level of GSK-3β phosphorylated at serine 9 (S9) and significantly increased the level of β-catenin phosphorylated at S33 and S37. We conclude that SeMet suppresses the growth of HT-29 colorectal cancer cells by the mechanism linked to the Wnt/β-catenin pathway, however, the degradation of β-catenin may occur independently of GSK-3β catalytic activity and its phosphorylation status.

This study was established to investigate the effects of cisplatin nano-liposomes on the apoptosis of the human retinoblastoma (RB) cell line Y79 in vitro and in vivo. Y79 cells were cultured and then exposed to Annexin V/PI to test their apoptosis, tested with the Caspase-3 activity detection kit to examine the change in activity of Caspase-3, and subjected to western blotting to test Bcl-2 and Bax protein expression. Y79-cell-transplanted tumor model in nude mice was also established and divided into three groups, with five nude mice in each. Cisplatin nano-liposomes were applied to the experimental group, cisplatin was injected into the control group, while saline was administered to the blank group, after which the nude mice were killed and the tumor was removed. Tumor volumes and weights in the three groups were compared. Nucleic acid extraction from magnetic beads was adopted to extract DNA, RT-PCR was employed to test Bcl-2 and Bax mRNA levels in tumor tissues, and in situ cell death assay kit was applied to test apoptotic cells. In comparison to the cisplatin solution and DMSO groups, the cisplatin liposome group showed higher Y79 apoptotic rate, Caspase-3 activity, and Bax protein expression, and lower Bcl-2 protein expression (all P < 0 05). In comparison with the control and blank groups, the experimental group showed lower tumor volume, weight, and Bcl-2 mRNA level of nude mice. In addition, in comparison with the control group, the experimental group showed higher cellular apoptotic rate and Bax mRNA level. In terms of the clinical effects of cisplatin nano-liposomes on a tumor transplant in nude mice with cervical cancer, they were shown to promote tumor apoptosis.

432 Background: KRN330 is a novel recombinant human IgG1 monoclonal antibody (mAb) targeting A33 surface differentiation antigen that is uniformly expressed on the surface of 95% of colorectal cancer (CRC) cells. In this study, we characterized the activity of KRN330 for its in vitro properties, as well as for its in vivo antitumor activity. Methods: A kinetic analysis of the interaction between KRN330 and recombinant human A33 was conducted using a Biacore 3000. Western blot analysis was conducted using A33 expressing COLO205 lysates under reducing and non-reducing conditions. Binding of KRN330 to human colorectal cancer tissues were investigated using FITC-labeled KRN330. We also developed more conventional staining methods of A33 and investigated A33 expression using human colon cancer tissue microarray (TMA). ADCC and CDC activities of KRN330 were assessed using a standard 51Cr release assay. A33 expression levels of 14 CRC cell lines were analyzed using flow cytometer. In vivo antitumor activities of KRN330 alone or in combination with chemotherapeutic agents against subcutaneous or intraperiotoneal human CRC (COLO205 and LS174T) models were investigated using mice and rats xenograft model. Results: A kinetic analysis revealed that KRN330 showed a high binding affinity to A33. Western blot analysis also showed that antibody recognized not any protein under reducing condition, but non-reducing condition. A33 staining of TMA with 204 different samples revealed the majority of tumor expressed A33. KRN330 exhibited ADCC activity against A33 expressing human colorectal cancer cell lines which include both K-ras wild and mutated types. KRN330 showed dose-dependent antitumor activities in vivo. KRN330 also significantly prolonged survival of human colon tumor bearing mice. In addition, combination treatment of KRN330 with irinotecan showed increased antitumor activitiy and prolongation of survival, compared to either irinotecan or KRN330 alone. Conclusions: These results suggest that KRN330 is a promising candidate of novel therapy for CRC. The phase I/II study of KRN330 plus irinotecan in patients with second line metastatic CRC is ongoing. [Table: see text]

Purpose: To explore the antitumor activity of wogonoside on bladder cancer, and its underlying mechanism of action. Methods: Methyl thiazolyl tetrazolium (MTT) assay was applied to determine the anti-proliferative activity of wogonoside (2 - 128 μM) on bladder cancer 5637 cell line at various times, and the halfmaximal inhibitory concentration (IC50) was measured. The antitumor activity of wogonoside (30 mg/kg, ip) against bladder cancer 5637 cell line was evaluated in nude mice bearing human bladder cancer 5637 cells. Additionally, western blotting and enzyme-linked immunosorbent assay (ELISA) were carried out to investigate the levels of the caspase-3, caspase-9, B cell lymphoma/leukemia-2 (Bcl-2), Bcl-2 associated X-protein (Bax), phosphorylated (p)-glycogen synthase kinase (GSK)-3β, p-extracellular signal-regulated kinases (p-ERK), and p-(protein kinase B) AKT. Results: The in vitro results revealed that wogonoside exerted anti-proliferative activity against bladder cancer 5637 cells with an IC50 of 20.59 μM (p < 0.01), in a concentration- and time-dependent manner. Furthermore, wogonoside treatment also significantly suppressed tumor volume in mice (p < 0.01). The potential mechanisms were mainly associated with apoptosis mediated by mitochondria via upregulation of caspase-3, caspase-9, and Bax levels and down-regulation of Bcl-2, p-GSK-3β, p-ERK, and p-AKT. Conclusion: The results reveal that wogonoside has remarkable anti-tumor potentials against bladder cancer. Further translational studies are warranted to test the clinical application of this medicinal agent in bladder cancer.

AbstractDeficiency of p53 in cancer cells activates the transformation of normal tissue fibroblasts into carcinoma-associated fibroblasts; this promotes tumor progression through a variety of mechanisms in the tumor microenvironment. The role of autophagy in carcinoma-associated fibroblasts in tumor progression has not been elucidated. We aimed to clarify the significance of autophagy in fibroblasts, focusing on the TP53 status in co-cultured human colorectal cancer cell lines (TP53-wild-type colon cancer, HCT116; TP53-mutant colon cancer, HT29; fibroblast, CCD-18Co) in vitro. Autophagy in fibroblasts was significantly suppressed in association with ACTA2, CXCL12, TGFβ1, VEGFA, FGF2, and PDGFRA mRNA levels, when co-cultured with p53-deficient HCT116sh p53 cells. Exosomes isolated from the culture media of HCT116sh p53 cells significantly suppressed autophagy in fibroblasts via inhibition of ATG2B. Exosomes derived from TP53-mutant HT29 cells also suppressed autophagy in fibroblasts. miR-4534, extracted from the exosomes of HCT116sh p53 cells, suppressed ATG2B in fibroblasts. In conclusion, a loss of p53 function in colon cancer cells promotes the activation of surrounding fibroblasts through the suppression of autophagy. Exosomal miRNAs derived from cancer cells may play a pivotal role in the suppression of autophagy.

Metastasis associated lung adenocarcinoma transcript 1 (MALAT1) is a highly conserved long noncoding RNA, which has been related to various pathological processes, including cancer. The role and mechanism of MALAT1 in colon cancer are not clear. We investigated MALAT1 expression in colon cancer tissues, the effect of MALAT1 on proliferation and apoptosis of SW480 cells, and the signaling pathway involved in the MALAT1 effects. MALAT1 expression was determined in 60 colon cancer and para-carcinoma tissues using reverse transcription polymerase chain reaction (RT-PCR). Knockdown of MALAT1 in SW480 cells was induced by small interfering RNA (siRNA), and the cells were divided into three groups: untreated control, nonsense siRNA-treated control, and MALAT1 siRNA-treated group. SW480 cell apoptosis was assessed using TUNEL assay and flow cytometry. Apoptosis-related and Wnt/β-catenin signaling pathway-related proteins were detected by Western blotting in SW480 cells. SW480 cell proliferation was assessed by CCK-8 assay. MALAT1 expression was significantly higher in colon cancer vs. para-carcinoma tissues. Knockdown of MALAT1 by siRNA increased the number of apoptotic cells and the apoptosis rate at 24 h post-transfection in SW480 cells. Bcl2 associated X protein (Bax) expression was increased, B-cell lymphoma 2 (Bcl-2) expression was decreased, and the ratio of cleaved caspase-3 to truncated caspase-3 was increased in MALAT1 siRNA-transfected SW480 cells. MALAT1 knockdown decreased the proliferation of SW480 cells at 24 h, 48 h, and 72 h post-transfection. Wnt and β-catenin expression was inhibited in MALAT1 siRNA-transfected SW480 cells. Inhibition of MALAT1 expression in colon cancer may promote apoptosis and hinder cell proliferation by suppressing the activation of Wnt/β-catenin signaling pathway.

The aim of this study is to explore the inhibitory effects of RNA interference (RNAi) targeting NET-1 or combined with sorafenib on HCCin vitroandin vivoand the possible underlying mechanisms. The expressions of NET-1 mRNA and protein were detected by RT-QPCR and western blot. The ability of proliferation was determined by CCK-8 assay. Apoptosis was examined by flow cytometry (FCM). Abilities of migration and invasion were measured by scratch-wound assay and transwell assay. MHCC97H cells with stable transfection of NET-1shRNA were injected subcutaneously to prepare nude mice model of HCC and Caspase-3, Caspase-8, and Caspase-9 mRNAs of tumor tissues in different groups were examined. NET-1 mRNA and protein were reduced sharply in MHCC97H cells transfected with NET-1shRNA. The abilities of proliferation and migration were inhibited and apoptosis was promoted in either NET-1shRNA or sorafenib as compared with untreated cellsin vitroandin vivo(P<0.05). The mRNA levels of caspase-3, caspase-8, and caspase-9 of tumor tissues were reduced in different treatment groups compared with untreated group, particularly in combination group. (P<0.05). The combination NET-1shRNA with sorafenib dramatically enhanced the effects of sorafenib antitumor ,which may involve in blocking ras signaling pathway and stimulating apoptotic pathways simultaneously.

<P>Background: Despite new agent development and short-term benefits in patients with Colorectal Cancer (CRC), metastatic CRC cure rates have not improved due to high rates of oxaliplatin resistance and toxicity. There is an urgent need for effective tools to prevent and treat CRC and reduce morbidity and mortality of CRC patients. Exploring the effects of bioactive peptides on the antitumor to CRC was of vital importance to the clinical application. </P><P> Objective: This study aimed to investigate the therapeutic impact of Anticancer Bioactive Peptides (ACBP) on anticancer effect of oxaliplatin (LOHP) in human colorectal cancer xenografts models in nude mice. </P><P> Methods: HCT-116 cells were cultured in vitro via CCK-8 assays and the absorbance was measured at 450 nm. Apoptosis and cell cycle were assessed by Flow Cytometry (FCM) in vitro. HCT-116 human colorectal cancer cells inoculated subcutaneously in nude mice of treatment with PBS (GG), ACBP, LOHP, ACBP+LOHP (A+L) in vivo. The quality of life was assessed by dietary amount of nude mice, the weight of nude mice, inhibition rates, tumor weight and tumor volume. Immunohistochemistry and RT-qPCR method was conducted to determine the levels of apoptosisregulating proteins/genes in transplanted tumors. </P><P> Results: ACBP induced substantial reductions in viable cell numbers and apoptosis of HCT116 cells in combined with LOHP in vitro. Compared with the control GG group, ACBP combined low dose oxaliplatin (U) group demonstrated significantly different tumor volume, the rate of apoptosis, the expression levels of Cyt-C, caspase-3,8,9 proteins and corresponding RNAs (P<0.05).

Objective: To overcome the disadvantages of cisplatin, numerous platinum (Pt) complexes have been prepared. However, the anticancer activity and mechanism of Pt(II) complexed with 2-benzoylpyridine [Pt(II)- Bpy]: [PtCl2(DMSO)L] (DMSO = dimethyl sulfoxide, L = 2-benzoylpyridine) in cancer cells remain unknown. Methods: Pt(II)-Bpy was synthesized and characterized by spectrum analysis. Its anticancer activity and underlying mechanisms were demonstrated at the cellular, molecular, and in vivo levels. Results: Pt(II)-Bpy inhibited tumor cell growth, especially HepG2 human liver cancer cells, with a halfmaximal inhibitory concentration of 9.8±0.5μM, but with low toxicity in HL-7702 normal liver cells. Pt(II)- Bpy induced DNA damage, which was demonstrated through a marked increase in the expression of cleavedpoly (ADP ribose) polymerase (PARP) and gamma-H2A histone family member X and a decrease in PARP expression. The interaction of Pt(II)-Bpy with DNA at the molecular level was most likely through an intercalation mechanism, which might be evidence of DNA damage. Pt(II)-Bpy initiated cell cycle arrest at the S phase in HepG2 cells. It also caused severe loss of the mitochondrial membrane potential; a decrease in the expression of caspase-9 and caspase-3; an increase in reactive oxygen species levels; the release of cytochrome c and apoptotic protease activation factor; and the activation of caspase-9 and caspase-3 in HepG2 cells, which in turn resulted in apoptosis. Meanwhile, changes in p53 and related proteins were observed including the upregulation of p53, the phosphorylation of p53, p21, B-cell lymphoma-2-associated X protein, and NOXA; and the downregulation of B-cell lymphoma 2. Moreover, Pt(II)-Bpy displayed marked inhibitory effects on tumor growth in the HepG2 nude mouse model. Conclusion: Pt(II)-Bpy is a potential candidate for cancer chemotherapy.
