Objectives:
The aim of the study was estimating the expression of isoforms of mRNA vascular endothelial growth factor: VEGF121, VEGF145, VEGF165, VEGF183, VEGF189, VEGF206, in tissue samples of vulvar cancer, normal and inguinal lymph nodes metastases.
Materials And Methods:
The material for this investigation of expression of mRNA selected genes was 4 tissue specimens from women with vulvar cancer T1N2M0. The method used for quantitative determination of the numbers of mRNA copies of selected genes was the QRT-PCR and QPCR technique, with the use of an ABI PRISM 7700 (TaqMan) sequence detector. The nucleotide sequence for starters and probes for quantitative RT-PCR was designed with the use of the Primer Express Version 1.0 ABI PRISM software.
Results:
Expression of all mRNA isoforms VEGF was found in the samples. The number of mRNA copies obtained in 1 microgram total mRNA extract of the genes examined in tissue sections with various pathomorphology were clearly differentiated.
Conclusions:
Expression profile of aforementioned genes indicated a definitive relationship between vascular endothelial growth factor isoform and vulvar cancer. These findings provide evidence that the expression pattern of mRNA VEGF isoform should find broad applications in clinical and research settings.
