The ability to measure mRNA encoding protein is attractive, since, provided certain criteria are met, the investigator can be confident of highly selective detection. In addition, changes in mRNA expression as well as their precise cellular localization, provides the scientist with important information that may not be evident by the detection of the translated protein. Hence, the combined approach of assessing mRNA and protein expression will often allow a more precise hypothesis to be formulated. In the present chapter, we describe methods we have optimized for the detection of mRNA following extraction from tissue or cells (Northern hybridization) and the detection of specific mRNA transcripts within their synthesising cells (in situ hybridization).

Elephant endotheliotropic herpesvirus (EEHV) causes lethal hemorrhagic disease (HD) in Asian and African elephants in human care and the wild. It is the leading cause of death for young Asian elephants in North American and European zoos despite sensitive diagnostic tests and improved treatments. Thus, there is a critical need to develop an effective vaccine to prevent severe illness and reduce mortality from EEHV-HD.

Insertions of the transposable element IS5 into its target sites in response to stressful environmental conditions, DNA structures, and DNA-binding proteins are well studied, but how the genomic contexts near IS5's native loci impact its transpositions is largely unknown. Here, by examining the roles of all 11 copies of IS5 within the genome of strain BW25113 in transposition, we reveal that the most significant copy of IS5 is one nested within and oriented in the same direction as the gene, while two other copies of IS5 harboring point mutations are hardly transposed. Transposition activity is heavily reliant on the upstream promoter that drives IS5 transposase gene , with more transpositions resulting from greater promoter activity.

EsxB (CFP-10) and EsxA (ESAT-6) are secreted effectors required for the function of ESX-1 systems. While some transcription factors regulating the expression of and have been identified, little work has addressed their promoter structures or other determinants of their expression.

DNA polymerases frequently misincorporate ribonucleoside 5'-triphosphates into nascent DNA strands. This study examined the effects of an incorporated ribonucleoside on untargeted mutations in human cells. Riboguanosine (rG) was introduced into the downstream region of the gene to preferentially detect the untargeted mutations.

Head and neck squamous cell carcinoma (HNSCC) with discordant diagnostic patterns of HPV/p16 or HPV/p16 correlate with worse prognosis. This study aims to identify truly HPV-driven HNSCCs using a QuantiGene-Molecular-Profiling-Histology (QG-MPH) assay for identifying transcriptionally active HPV. Of 97 FFPE samples analyzed, 68 were valid for HPV DNA detection by PCR and quantification of HPV E7 and p16 mRNA by QG-MPH.
