[Abstract] Long noncoding RNAs (lncRNAs) play essential roles in normal physiology and in disease but their mechanisms of action can be challenging to identify. For mechanistic studies, it is often useful to know a lncRNA’s intracellular abundance, i.e., approximately how many molecules of the lncRNA are present in a typical cell of a cell-type of interest. At least two approaches have been used to approximate lncRNA intracellular abundance: single-molecule sensitivity RNA fluorescence in situ hybridization (smFISH) and single-gene, calibrated reverse-transcription followed by quantitative PCR (RT-qPCR). However, like all experimental approaches, these methods have their limitations. smFISH, when analyzed using diffraction-limited microscopy, can underestimate intracellular ...
[摘要] [摘要]长非编码RNA（lncRNA）在正常生理和疾病中起着至关重要的作用，但其作用机理可能难以鉴定。对于机理研究，了解lncRNA的胞内丰度（即在目标细胞类型的典型细胞中大约存在多少个lncRNA分子）通常很有用。至少两种方法已用于估算lncRNA细胞内丰度：单分子敏感性RNA荧光原位杂交（smFISH ...
