The siRNA cocktail targeting VEGF and HER2 inhibition on the proliferation and induced apoptosis of gastric cancer cell.
Abstract The aim of this study was to investigate the inhibitory effect of a siRNA cocktail targeting Vascular endothelial growth factor (VEGF) and Human epidermal growth factor receptor 2 (HER2) on cell proliferation, induced apoptosis and the expression of VEGF and HER2 in human gastric carcinoma cell. The silencing rate of pre-designed siRNAs that targeted VEGF and HER2 was detected by Real-time Quantitative PCR (RT-QPCR) analysis. Furthermore, the best silencing siRNA that targeted VEGF and HER2 was prepared as a cocktail to co-knockdown VEGF and HER2 expression at both mRNA and protein levels which were detec...

The inhibitory effect of a new scFv/tP protein as siRNA delivery system to target hWAPL in cervical carcinoma.
Abstract Targeted immunotherapy has become a popular research topic in cancer. The development and metastasis of cervical carcinoma are closely related to epidermal growth factor (EGF) and EGF-1 receptor (EGFR). We successfully constructed a single-chain human anti-EGFR antibody (scFv) and truncated protamine (tP) fusion protein (scFV/tP) expression vector using overlap extension PCR. Enzyme-linked immunosorbent assay and gel shift assay showed that the fusion protein retained the DNA and antigen-binding activity of the original antibody. Using the non-viral scFv/tP vector as a delivery tool, small interfering RNA...

Expression of HAb18G in non-small lung cancer and characterization of activation, migration, proliferation, and apoptosis in A549 cells following siRNA-induced downregulation of HAb18G.
Abstract HAb18G, a novel cancer biomarker, has been shown to be involved in the progression of malignancy by regulating expression of vascular endothelial growth factor (VEGF) and matrixmetalloproteinases (MMPs). The goal of this study was to evaluate the role of HAb18G in the biology of NSCLC and to determine its potential as a therapeutic target. HAb18G protein expression was detected by immunohistochemistry in 150 NSCLC tissues. The results showed that HAb18G protein expression was associated with tumor diameter, lymph node status, tumor stage, and poor prognosis (P < 0.05). Multivariate analysis showed th...

New perspectives in triple-negative breast cancer therapy based on treatments with TGF β1 siRNA and doxorubicin.
In this study, a combined doxorubicin (DOX) and small interfering RNA (siRNA) therapy is proposed as therapeutic strategy for targeting TGFβ1 gene. Hs578T cell line is used as in vitro model for TNBC, wherein TGFβ1siRNA therapy is employed to enhance therapeutic effects. Cell proliferation rate is measured using an MTT test, and morphological alterations are assed using microscopically approached, while gene expression is determined by qRT-PCR analysis. The combined treatment of TGFβ1siRNA and DOX reduced levels of cell proliferation and mitochondrial activity and promoted the alteration of cell morphology (dark-field m...

EZH2 promotes cell proliferation by regulating the expression of RUNX3 in laryngeal carcinoma.
Abstract Enhancer of zeste homolog 2 (EZH2) is a highly conserved histone methyltransferase, which is overexpressed in different types of cancers such as breast and prostate cancer. It is reported that EZH2 can directly down-regulate RUNX3 by increasing histone H3 methylation. However, the role of EZH2 in the development and progression of laryngeal carcinoma has not yet been investigated, and the relationship between EZH2 and RUNX3 in laryngeal carcinoma is rarely reported. The current study aims to determine the role of EZH2 in the progression of laryngeal carcinoma, and investigate the interaction between EZH2 ...

miR-21 modulates chemosensitivity of tongue squamous cell carcinoma cells to cisplatin by targeting PDCD4.
In this study, we investigated the effects and molecular mechanisms of miR-21 in chemosensitivity of tongue squamous cell carcinoma cells (TSCC) to cisplatin. miR-21 expression was detected in tongue cancer tissue using RT-PCR and PDCD4 protein expression was measured using immunohistochemistry. miR-21 and(or) PDCD4 depleted cell lines were generated using miR-21 inhibitor and(or) siRNA. The viabilities of treated cells were analyzed using MTT assay. RT-PCR was used to detect miR-21 expression and immunoblotting was used to detect protein levels. Cell cycle and apoptosis were analyzed using propidium iodide (PI) staining a...

Pin1 modulates chemo-resistance by up-regulating FoxM1 and the involvements of Wnt/β-catenin signaling pathway in cervical cancer.
Abstract The prolyl isomerase Pin1, which is frequently highly expressed in many different cancers, can directly regulate cell proliferation and the cell cycle. However, the role of Pin1 in chemo-resistance remains to be elucidated in cervical cancer. The purpose of the present study was to investigate the role of Pin1 in the chemo-resistance of cervical cancer. The cisplatin resistance was assessed using the MTT assay. Pin1, FoxM1, β-catenin, Cyclin D1, and c-myc expression levels were detected by RT-qPCR or Western blot. The results showed that Pin1 expression displayed a similar expression pattern with the res...

Knockdown BMI1 expression inhibits proliferation and invasion in human bladder cancer T24 cells.
Abstract B cell-specific moloney murine leukemia virus integration site 1 (BMI1) is a transcriptional repressor of polycomb repressive complex 1, which is involved in the proliferation, senescence, migration, and tumorigenesis of cancer. Experimental researchers have convincingly linked BMI1 to tumorigenesis. However, there is no study about the issue on the role of BMI1 in the proliferation, apoptosis, and migration of bladder cancer. To address this question, we examined the expression of BMI1 in bladder cancer tissues and used siRNA to knockdown BMI1 expression in bladder cancer T24 cells. Then we tested the ce...

p53siRNA therapy reduces cell proliferation, migration and induces apoptosis in triple negative breast cancer cells.
This study is intended to investigate, the potential applications of RNA interference (RNAi) to block p53 expression, as well as its subsequent effect on cell growth, apoptosis and migration on a triple negative human breast cancer cell line (Hs578T). p53siRNA significantly reduced cell index (CI) compared to the control and we observed an inhibition of cellular migration in the interval of time between 0 and 30 h, as shown in the data obtained by dynamic evaluation using the xCELLigence System. Also, by using PCR-array technology, a panel of 84 key genes involved in apoptosis was investigated. Our studies indicate that t...
