High Throughput Sequencing of Extracellular RNA from Human Plasma

The presence and relative stability of extracellular RNAs (exRNAs) in biofluids has led to an emerging recognition of their promise as 'liquid biopsies' for diseases. Most prior studies on discovery of exRNAs as disease-specific biomarkers have focused on microRNAs (miRNAs) using technologies such as qRT-PCR and microarrays. The recent application of next-generation sequencing to discovery of e...

Optimal Electroporation Condition for Small Interfering RNA Transfection into MDA-MB-468 Cell Line

Background: Electroporation is a valuable tool for small interfering RNA (siRNA) delivery into cells because it efficiently transforms a wide variety of cell types. Since electroporation condition for each cell type must be determined experimentally, this study presents an optimal electroporation strategy to reproducibly and efficiently transfect MDA-MB 468 human breast cancer cell with siRNA. ...

RNA sequencing identifies specific PIWI-interacting small non-coding RNA expression patterns in breast cancer

PIWI-interacting small non-coding RNAs (piRNAs) are genetic and epigenetic regulatory factors in germline cells, where they maintain genome stability, are involved in RNA silencing and regulate gene expression. We found that the piRNA biogenesis and effector pathway are present in human breast cancer (BC) cells and, analyzing smallRNA-Seq data generated from BC cell lines and tumor biopsies, we...

Single-cell RNA sequencing identifies diverse roles of epithelial cells in idiopathic pulmonary fibrosis.

Idiopathic pulmonary fibrosis (IPF) is a lethal interstitial lung disease characterized by airway remodeling, inflammation, alveolar destruction, and fibrosis. We utilized single-cell RNA sequencing (scRNA-seq) to identify epithelial cell types and associated biological processes involved in the pathogenesis of IPF. Transcriptomic analysis of normal human lung epithelial cells defined gene expr...
