چکیده

More antibody validation protocols would identify non-specific reagents - a major source of irreproducible research - with the inclusion of negative controls. This article presents an overview of one such method: siRNA knockdown. The authors outline a general protocol, the knockdown mechanism, and tips for evaluating knockdown experiments.

Study of the role of siRNA mediated promoter methylation in DNMT3B knockdown and alteration of promoter methylation of CDH1, GSTP1 genes in MDA-MB -453 cell line

Promoter methylation is one of the main epigenetic mechanisms that lead to the inactivation of tumor suppressor genes during carcinogenesis. Due to the reversible nature of DNA methylation, many studies have been performed to correct theses epigenetic defects by inhibiting DNA methyltransferases (DNMTs). In this case novel therapeutics especially siRNA oligonucleotides have been used to specifi...

Decreasing Eukaryotic Initiation Factor 3C (EIF3C) Suppresses Proliferation and Stimulates Apoptosis in Breast Cancer Cell Lines Through Mammalian Target of Rapamycin (mTOR) Pathway

BACKGROUND Translation initiation is the rate limiting step of protein synthesis and is highly regulated. Eukaryotic initiation factor 3C (EIF3C), an oncogene overexpressed in several human cancers, plays an important role in tumorigenesis and cell proliferation. MATERIAL AND METHODS Immunohistochemistry was used to determine the expression of EIF3C in breast cancer tissues from 42 patients. We...

Specificity of short interfering RNA determined through gene expression signatures.

Short interfering RNA (siRNA) is widely used for studying gene function and holds great promise as a tool for validating drug targets and treating disease. A critical assumption in these applications is that the effect of siRNA on cells is specific, i.e., limited to the specific knockdown of the target gene. In this article, we characterize the specificity of siRNA by applying gene expression p...

Validating Antibodies to the Cannabinoid CB2 Receptor

The problem of antibody reliability in research has now reached the point where many journals reject any work that lacks adequate controls for antibody validation. Despite this, it is still common for researchers to rely on positive controls and only minimal negative controls (such as blocking peptide controls). Using careful cross-comparisons between antibody labeling and other labeling techni...
