About This Topic

Fluorescence in situ hybridization (FISH) is an approach applied and applicable in many fields of biological research and diagnostics. Its unique feature is to provide information on localization and copy numbers of specific stretches of nucleic acids on the single cell level. Thus, FISH cannot be replaced by, like in medical field at present very popular ‘high throughput approaches’, which are mostly providing information on the genetic content of thousands to millions of cells at a time. FISH provides multiple possibilities and variants, according to the question to be answered. Fluorescence in situ hybridization can be applied as (i) single to multi-color FISH approaches, (ii) using DNA, RNA, cDNA, PNA, and other types of labeled nucleotides as probes; also (iii) samples for FISH can be various human, animal or plant derived tissue types, and even single cellular organisms.

In this special issue of OBM Genetics, we have selected topics that highlight the progress, the state-of–the-art and future potential of fluorescence in situ hybridization, ranging from practical and technological aspects to applications in research and diagnostics of fluorescence in situ hybridization in human, animal, plant, fungi, biofilms and bacteria. Overall this issue provides information where and how fluorescence in situ hybridization can be applied in practice, and shows its high potential in diagnostics and research.

Abstract:
Background: The method of cellular compartment analysis of temporal activity by fluorescent in situ hybridization (catFISH) is widely used in the cellular and behavioral neurobiology. It exploits stimulus-induced expression of immediate early genes (IEGs), mostly Arc or c-fos, and allows identification of two neuronal populations activated in the brain of the same animal in response to neural or behavioral events spaced by 25 to 30 min. The differential labeling of two populations is based on the visualization of nuclear and cytoplasmic mRNA which is accumulated in neurons at different intervals after their activation. However, the drawback of this method is that the two mRNA forms are labeled by the same color which complicates their discrimination during image analysis.
Methods: We describe a protocol for the two-color c-fos catFISH that allows visualization of the cytoplasmic (stimulus 1) and nuclear (stimulus 2) mRNA not only by their intracellular localization but also by the color-coded labeling of spliced and unspliced forms of c-fos mRNA using the combination of digoxigenin- and biotin-conjugated probes. We also demonstrate possibility of combining this protocol with immunofluorescent detection of c-Fos protein, which allows visualization of two neuronal populations activated in the same brain by stimuli spaced from 30 up to 60 min.
Results: We used the developed protocol for two-color c-fos catFISH to identify neuronal populations activated in the mouse brain by two distinct cognitive simuli. We identified two color signals that corresponded to cytoplasmic and nuclear c-fos mRNA in different brain regions after mice were exposed to two different contexts separated by an interval of 20 minutes. Two-color c-fos catFISH protocol was also combined with с-Fos immunohistochemistry, allowing colocalization of c-fos mRNA and с-Fos protein activated by two contextual stimuli spaced by 60 min.
Conclusions: The combination of the proposed approaches allows visualization of neuronal populations activated in the brain of the same animal during more than two cognitive episodes and in the time window up to 60 min.
