| Research Abstract |
In situ reverse transcriptase-polymerase chain reaction (in situ RT-PCR) is a newly developed technique that allows in situ amplification of reverse-transcribed complementary DNA (cDNA) originating from mRNA. The technique is considered to be more suitable for in situ detection of target mRNA in routinely processed formalin-fixed paraffin-embedded tissue sections than in situ hybridization. We developed convenient in situ RT-PCR techniques for osteopontin and vascular endothelial growth factor mRNAs. Furthermore, synovial sarcoma, which is characteristic of chimeric SYT-SSX gene, is proved to express the chimeric transcript in all tumor cells by in situ RT-PCR. A significant inverse correlation between p27 expression and apoptosis was demonstrated in synovial sarcoma. A combination of p27 expression and apoptosis allowed more accurate estimation of prognosis of patients with synovial sarcoma than each parameter alone
