DNA mutations of various types often affect the cellular localization and function of gene products. The role of mutant transcripts in the pathogenesis of human disease is increasingly recognized. Among the pathogenic RNA variants are transcripts with single nucleotide substitutions, small insertions or deletions, aberrantly or alternatively spliced transcripts and RNAs derived from fused genes. To...
The first methods for visualizing RNAs within cells were designed for simple imaging of specific transcripts in cells or tissues and since then significant technical advances have been made in this field. Today, high-resolution images can be obtained, enabling visualization of single transcript molecules, quantitative analyses of images, and precise localization of RNAs within cells as well as co-localization...
RNA fluorescence in situ hybridization (FISH) is a widely used technique for detecting transcripts in fixed cells and tissues. Many variants of RNA FISH have been proposed to increase signal strength, resolution and target specificity. The current variants of this technique facilitate the detection of the subcellular localization of transcripts at a single molecule level. Among the applications of...
