In situ hybridization (ISH) is a technique to determine potential correlations between viruses and lesions. The aim of the study was to compare ISH techniques for the detection of various viruses in different tissues. Tested RNA viruses include atypical porcine pestivirus (APPV) in the cerebellum of pigs, equine and bovine hepacivirus (EqHV, BovHepV) in the liver of horses and cattle, respectively, and Schmallenberg virus (SBV) in the cerebrum of goats. Examined DNA viruses comprise canine bocavirus 2 (CBoV-2) in the intestine of dogs, porcine bocavirus (PBoV) in the spinal cord of pigs and porcine circovirus 2 (PCV-2) in cerebrum, lymph node, and lung of pigs. ISH with self-designed digoxigenin-labelled RNA probes revealed a positive signal for SBV, CBoV-2, and PCV-2, whereas it was lacking for APPV, BovHepV, EqHV, and PBoV. Commercially produced digoxigenin-labelled DNA probes detected CBoV-2 and PCV-2, but failed to detect PBoV. ISH with a commercially available fluorescent ISH (FISH)-RNA probe mix identified nucleic acids of all tested viruses. The detection rate and the cell-associated positive area using the FISH-RNA probe mix was highest compared to the results using other probes and protocols, representing a major benefit of this method. Nevertheless, there are differences in costs and procedure time.

We developed a simple and rapid technique to synthesize single-stranded DNA (ssDNA) probes for fluorescent in situ hybridization (ISH) to human immunodeficiency virus 1 (HIV-1) RNA. The target HIV-1 regions were amplified by the polymerase chain reaction (PCR) and were simultaneously labeled with dUTP. This product served as template for an optimized asymmetric PCR (one-primer PCR) that incorporated digoxigenin (dig)-labeled dUTP. The input DNA was subsequently digested by uracil DNA glycosylase, leaving intact, single-stranded, digoxigenin-labeled DNA probe. A cocktail of ssDNA probes representing 55% of the HIV-1 genome was hybridized to HIV-1-infected 8E5 T-cells and uninfected H9 T-cells. For comparison, parallel hybridizations were done with a plasmid-derived RNA probe mix covering 85% of the genome and a PCR-derived RNA probe mix covering 63% of the genome. All three probe types produced bright signals, but the best signal-to-noise ratios and the highest sensitivities were obtained with the ssDNA probe. In addition, the ssDNA probe syntheses generated large amounts of probe (0.5 to 1 μg ssDNA probe per synthesis) and were easier to perform than the RNA probe syntheses. These results suggest that ssDNA probes may be preferable to RNA probes for fluorescent ISH.

During limb development, type I collagen disappears from the region where cartilage develops and synthesis of type II collagen, which is characteristic of cartilage, begins. In situ hybridization using antisense RNA probes was used to investigate the spatial localization of type I and type II collagen mRNAs. The distribution of the mRNA for type II collagen corresponded well with the pattern of type II collagen synthesis, suggesting control at the level of transcription and mRNA accumulation. In contrast, the pattern of mRNA for type I collagen remained more or less uniform and did not correspond with the synthesis of the protein, suggesting control primarily at the level of translation or of RNA processing.

Abstract In situ hybridization using antisense RNA probes was used to localize cells that produce erythropoietin (EPO) in the livers of anemic transgenic mice expressing the human EPO gene and in livers of anemic nontransgenic mice. In transgenic mice bled from a hematocrit of 55% to one of 10%, hepatocytes surrounding central veins synthesized large amounts of human EPO mRNA. EPO-producing cells were very rare in the area of portal triads. In transgenic mice bled to a hematocrit of 20%, a similar number and distribution of cells contained human EPO mRNA as was found with a 10% hematocrit, but the cells were less heavily labeled, indicating increased EPO production per cell at 10% hematocrit as compared with 20% hematocrit. No human EPO mRNA was detected in the kidneys of anemic transgenic mice, although endogenous murine EPO mRNA was strongly expressed in cortical interstitial cells. In sections of livers from nontransgenic mice bled from a hematocrit of 45% to one of 10%, only isolated cells produced EPO. When the types of cells could clearly be identified, approximately 80% of these cells were hepatocytes, while 20% had a nonepithelial morphology and were located in or adjacent to the sinusoidal spaces. When the sense strand was used as the RNA probe for in situ hybridization, no labeled cells were seen in normal or anemic livers. These results demonstrate that hepatocytes are responsible for production of EPO in both transgenic and nontransgenic mice and that a second cell type that is similar in morphology to EPO-producing interstitial cells in the kidney also produces EPO in the livers of nontransgenic mice.

In situ hybridization using nonradioactively-labeled RNA probes is a technique that combines understanding of basic molecular biology and histopathologic interpretation. Recombinant or PCR technology can be used to produce probes that hybridize with a wide variety of cellular genes and infectious agents. Hybridization conditions can be optimized for each probe/target combination.
