Inhibition of SMYD2 Sensitized Cisplatin to Resistant Cells in NSCLC Through Activating p53 Pathway
In conclusion, the present study elucidated that the activity of SMYD2 in NSCLC may affect the cell sensitivity to chemotherapeutic agents, especially to CDDP. The elevated SMYD2 mediated CDDP resistance and malignant phenotype in NSCLC, indicating that SMYD2 may be a useful biomarker of CDDP resistance in NSCLC. Inhibition of SMYD2 contributes to the methylation-related activation of p53 and thus results in cell apoptosis. Furthermore, combination treatment with CDDP and an SMYD2 inhibitor had a synergistically antitumor effects in a xenograft model in vivo. Given that SMYD2 has reversible effects and is a targetable prot...

Endothelial Cell-Derived TGF- β Promotes Epithelial-Mesenchymal Transition via CD133 in HBx-Infected Hepatoma Cells
Conclusion: The study indicates that secretory factors like TGF-β from neighboring endothelial cells may enhance expression of CD133 and impart an aggressive EMT phenotype to HBx-infected hepatoma cells in HBV induced HCC. Introduction Hepatocellular Carcinoma (HCC) is one of the most common cancer worldwide, representing approximately 4% of all malignancies (1). It has been estimated that more than 50% of HCC cases in the world are associated with hepatitis B virus (HBV) (2). HBV is a partially double stranded DNA virus belonging to the Hepadnavirus family. The HBV genome is 3.2 kb in size and contains fou...

Non-canonical Notch Signaling Regulates Actin Remodeling in Cell Migration by Activating PI3K/AKT/Cdc42 Pathway
In conclusion, our research results indicate that DAPT activates PI3K/AKT/Cdc42 signaling by non-canonical Notch pathway, and the activated Cdc42 promotes the filopodia formation and inhibits lamellipodia assembly, resulting in reduced migration of breast cancer cells. The results imply that non-canonical Notch signaling may play a very important role in the rapid response of cells to the extracellular signals. Author Contributions LG, JD, and LL designed the study and wrote and revised the manuscript. LL and LZ performed most of the experiments and data analysis. SZ, X-YZ, P-XM, Y-DM, Y-YW, YC, S-JT, and Y-JZ assisted i...

Small interfering RNA-mediated suppression of serum response factor, E2-promotor binding factor and survivin in non-small cell lung cancer cell lines by non-viral transfection BASIC SCIENCE
CONCLUSIONS This study reports a reliable transfectability of NSCLC-cell lines by siRNA, initially in a non-viral manner, and a reproducible knockdown of the focussed targets, consequently leading to the death of the tumour cells. This constitutes a strong candidate for a new assessment strategy in the therapy of non-small cell lung cancer.

Therapeutic targeting of polo-like kinase 1 using RNA-interfering nanoparticles (iNOPs) for the treatment of non-small cell lung cancer.
Authors: McCarroll JA, Dwarte T, Baigude H, Dang J, Yang L, Erlich RB, Kimpton K, Teo J, Sagnella SM, Akerfeldt MC, Liu J, Phillips PA, Rana TM, Kavallaris M Abstract Non-small cell lung cancer (NSCLC) remains the most common cause of cancer death worldwide due its resistance to chemotherapy and aggressive tumor growth. Polo-like kinase 1 (PLK1) is a serine-threonine protein kinase which is overexpressed in cancer cells, and plays a major role in regulating tumor growth. A number of PLK1 inhibitors are in clinical trial; however, poor tumor bioavailability and off-target effects limit their efficacy. Short-interfer...

Nedaplatin reduces multidrug resistance of non-small cell lung cancer by downregulating the expression of long non-coding RNA MVIH
In conclusion, LncRNA MVIH is upregulated in drug resistant NSCLC cells. Nedaplatin can reduce the expression of MVIH and reverse EMT process, thus reversing the drug resistance of cisplatin in non-small cell lung cancer cells.

Late-breaking abstract: EGFR specific single chain antibody deliver siRNAs restore gefitinib sensitivity in resistant NSCLC cells
To overcome TKIs resistance, we developed scFv and s-9R, two human single chain antibodies against EGFR(fig.1A). Here, we showed s-9R could deliver FAM-siRNA into EGFR positve NSCLC cells(fig.1B). A549, H1993 and H1975 were either transfected with KRAS, MET or EGFR siRNA or co-incubated with scFv/s-9R/ indicated siRNA mixtures, following treated with gefitinib. Compared with the control groups, the target genes' expression level were down-regulated in the s-9R/siRNA mixture groups detected by RT-qPCR and western blot(fig.1C and D). In vivo, s-9R/siRNA mixtures restored gefitinib sensitivity in TKIs resistance cells measure...

Abstract 2622: Fluorocyclopentenylcytosine (RX-3117) is activated by uridine-cytidine kinase 2, a potential biomarker
Fluorocyclopentenylcytosine (RX-3117) is an orally bioavailable novel cytidine analog, currently being tested in a Phase I clinical trial. RX-3117 shows promising antitumor activity in various human tumor xenografts including patient derived xenografts resistant to gemcitabine. Initial characterization of RX-3117 indicates that this compound is incorporated into both RNA and DNA, and downregulates DNA methyltransferase I (DNMT1). RX-3117 is not deaminated by cytidine deaminase, an enzyme that limits the efficacy of most cytidine analogs due to extensive deamination. Our studies also demonstrate that RX-3117 is taken up by ...

Mechanism of Wnt/β-catenin signaling pathway in enhanced malignant phenotype of non-small cell lung cancer induced by anti-angiogenesis therapy
Conclusions siRNA can significantly inhibit the expression of VEGF. For the anti-angiogenesis therapy, the inhibited expression of VEGF can activate the Wnt/β-catenin signaling pathway to cause the epithelial mesenchymal transition and then the enhanced malignant phenotype of non-small cell lung cancer.

Sanguinarine Induces Apoptosis Pathway in Multiple Myeloma Cell Lines via Inhibition of the JaK2/STAT3 Signaling
In this study, we aimed to investigate the potential anti-proliferative and pro-apoptotic activities of SNG in a panel of MM cell lines (U266, IM9, MM1S, and RPMI-8226). SNG treatment of MM cells resulted in a dose-dependent decrease in cell viability through mitochondrial membrane potential loss and activation of caspase 3, 9, and cleavage of PARP. Pre-treatment of MM cells with a universal caspase inhibitor, Z-VAD-FMK, prevented SNG mediated loss of cell viability, apoptosis, and caspase activation, confirming that SNG-mediated apoptosis is caspase-dependent. The SNG-mediated apoptosis appears to be resulted from suppres...

Impact of PLK-1 Silencing on Endothelial Cells and Cancer Cells of Diverse Histological Origin.
Abstract The main goal of this work was to assess in vitro the potential of Polo-like kinase gene (PLK-1) as a molecular target within the tumor microenvironment, namely in both cancer cells of tumors of different histological origin and endothelial cells from angiogenic blood vessels, upon silencing with anti-PLK-1 siRNA. In addition, the effect of Plk-1 downregulation on the cancer cells chemosensitization to paclitaxel was further assessed. Downregulation of Plk-1 reduced cancer cells viability from 40 to 85% and up to 59% in endothelial cells. Regarding the latter, it compromised their ability to form new tube...

Knockdown of TWIST1 enhances arsenic trioxide- and ionizing radiation-induced cell death in lung cancer cells by promoting mitochondrial dysfunction.
Abstract TWIST1 is implicated in the process of epithelial mesenchymal transition, metastasis, stemness, and drug resistance in cancer cells, and therefore is a potential target for cancer therapy. In the present study, we found that knockdown of TWIST1 by small interfering RNA (siRNA) enhanced arsenic trioxide (ATO)- and ionizing radiation (IR)-induced cell death in non-small-cell lung cancer cells. Interestingly, intracellular reactive oxygen species levels were increased in cells treated with TWIST1 siRNA and further increased by co-treatment with ATO or IR. Pretreatment of lung cancer cells with the antioxidan...

TRIM28 knockdown increases sensitivity to etoposide by upregulating E2F1 in non-small cell lung cancer.
Authors: Liu L, Xiao L, Liang X, Chen L, Cheng L, Zhang L, Wu X, Xu Q, Ma C Abstract Tripartite motif containing 28 (TRIM28) is a universal corepressor for Kruppel‑associated box zinc finger proteins. In our previous study, it was shown that expression of TRIM28 is upregulated in non‑small cell lung cancer (NSCLC) cell lines and tissues. Here, we demonstrated that the stable silencing of TRIM28 expression by a specific siRNA lentivirus vector increased the sensitivity of NSCLC cells to chemotherapeutic agent etoposide. Combination of TRIM28 siRNA and etoposide significantly inhibited the growth and proliferatio...
