This study aimed to investigate the inhibition of vascular endothelial growth factor (VEGF) by small hairpin RNA (shRNA) interference combined with radiotherapy on the growth of cervical cancer SiHa cell xenografts in nude mice. The effective pVEGF-shRNA plasmid was screened by reverse transcription-polymerase chain reaction (RT-PCR), and the cell apoptosis rate was estimated by flow cytometry....
RNA interference (RNAi) is a widely used molecular biology technique to investigate the importance of specific genes in molecular pathways. Since mammalian cells are equipped with endogenous RNAi processing machinery, it has become common practice to transfect constructs that encode for short hairpin RNAs that are then cleaved to form the active RNAi sequences that bind to target mRNAs. Given t...
Nucleophosmin (NPM1) is an abundant and ubiquitously expressed phosphoprotein that is known to influence solid tumors progression. However, little is known about the role of NPM1 in leukemia. Here, we knocked down the NPM1 expression by RNA interference to investigate the role of NPM1 in leukemic cells proliferation and apoptosis. The interference vector pNPM1-shRNA was constructed and transfec...
Five recent publications have documented the successful development and use of gene transfer vectors based on adeno-associated virus (AAV) for expressing short hairpin RNA (shRNA). In cultured mammalian cells and in whole animals, infection with these vectors was shown to result in specific, efficient, and stable knockdown of various targeted endo- or exogenous genes. Here we review this exciti...
Abstract Background Cholangiocarcinoma represents the second most common primary liver malignancy. The incidence rate has constantly increased over last decades. silent nature limits early diagnosis and prevents efficient treatment. Methods Immunoblotting immunohistochemistry were used to assess expression profiling of USP9X EGLN3 in cholangiocarcinoma patients. ShRNA was silence gene expressio...
INTRODUCTION Over-expression of penile neuronal nitric oxide synthase (PnNOS) from a plasmid ameliorates aging-related erectile dysfunction (ED), whereas over-expression of the protein inhibitor of NOS (PIN), that binds to nNOS, increases ED. AIM To improve this form of gene therapy for ED by comparing the electrical field response of short hairpin RNA (shRNA) for PIN with that of antisense P...
BACKGROUND/AIMS The present study aimed to analyze the mechanisms by which periodic mechanical stress is translated into biochemical signals, and to verify the important role of signaling molecules including phosphatidylinositol-3-kinase (PI3K)-Akt, protein kinase C (PKC), and epidermal growth factor receptor (EGFR) in chondrocyte proliferation. The effects of periodic mechanical stress on the ...
The oncogenic isoform of the p63 protein, delta Np63 (delta Np63), plays an important role in the pathogenesis of many epithelial carcinomas, and emerging evidences suggest that delta Np63 is a promising drug target. However, the functions of delta Np63 in transitional cell carcinoma of bladder (TCCB) are poorly defined. In this study, a delta Np63 shRNA expression vector was transfected into T...
RNA interference (RNAi) mediated by short hairpin-RNA (shRNA) expressing plasmids can induce specific and long-term knockdown of specific mRNAs in eukaryotic cells. To develop a vector-based RNAi model for Schistosoma mansoni, the schistosome U6 gene promoter was employed to drive expression of shRNA targeting reporter firefly luciferase. An upstream region of a U6 gene predicted to contain the...
shRNA overexpression from viral gene therapy vectors can trigger cytotoxicity leading to organ failure and lethality in mice and rats. This process likely involves saturation of endogenous cellular RNAi factors including exportin-5 (Xpo-5). Here, we have shown that Xpo-5 overexpression enhanced shRNA efficiency in the liver of adult mice but increased hepatotoxicity. We identified the 4 members...
