Interaction of RNA with transformed glucocorticoid receptor. II. Identification of the RNA as transfer RNA.

Enhancement of RNA Interference Effect in P19 EC Cells by an RNA-dependent RNA Polymerase

Background: RNA interference (RNAi) is a phenomenon uses double-stranded RNA (dsRNA) to specifically inhibit gene expression. The non-specific silencing caused by interferon response to dsRNA in mammalian cells limits the potential of utilizing RNAi to study gene function. Duplexes of 21-nucleotide short interfering dsRNA (siRNA) inhibit gene expression by RNAi. In some organisms, siRNA can als...

Study of Long Noncoding RNA FER1L4 and RB1, as Its Competing Endogenous RNA Network Target Gene, in Breast Cancer

Introduction: Breast cancer is the second most common cause of cancer-related death among females, which requires an exploration for markers to propose a more specific categorization of this cancer. Long noncoding RNAs (lncRNAs), the main subset of noncoding transcripts, are involved in tumorigenic processes. In this study, we investigated the expression of the fer-­1–­like family member 4 (FER...

The human glucocorticoid receptor as an RNA-binding protein: global analysis of glucocorticoid receptor-associated transcripts and identification of a target RNA motif.

Posttranscriptional regulation is emerging as a key factor in glucocorticoid (GC)-mediated gene regulation. We investigated the role of the human GC receptor (GR) as an RNA-binding protein and its effect on mRNA turnover in human airway epithelial cells. Cell treatment with the potent GC budesonide accelerated the decay of CCL2 mRNA (t(1/2) = 8 ± 1 min versus 62 ± 17 min in DMSO-treated cells) ...

RNA nanotechnology breakthrough for targeted release of RNA-based drugs using cell-based aptamers

Nucleic acids play different roles besides storing information and proteins coding. For example, single-stranded nucleic acids can fold into complicated structures with capability of molecular detection, catalyzing bioreactions and therapy. The development of RNA-based therapies has been rapidly progressed in the recent years. RNA aptamers are biomolecules with a size of 10 to 50 nm that can be...
