ZHANG Yi, et al. Expressions of PLGF and VEGFR-1 in invasive pituitary adenoma[J]. Journal of Chongqing Medical University, 2010,35(12):1825-1827. DOI: 10.13406/j.cnki.cyxb.2010.12.027.
Objective:To explore the expressions of PLGF(Placenta growth factor) and VEGFR-1(Vascular endothelial growth factor receptor-1) in pituitary adenoma and their relationship with the invasiveness of the adenoma.Methods:57 specimens of pituitary adenoma were classified into invasive and non-invasive group according to the comprehensive evaluation of invasive pituitary adenoma.The protein expressions of PLGF and VEGFR-1 were detected by immunohistochemical analysis and their mRNA expressions were detected by reverse transcription polymerase chain reaction(RT-PCR) in the invasive and non-invasive pituitary adenomas.Results:30 specimens of pituitary adenoma were invasive and 27 were non-invasive.The protein expressions of PLGF and VEGFR-1 were significantly higher in invasive pituitary adenomas than in non-invasive ones.Their mRNA expressions were higher in invasive pituitary adenomas too.Conclusion:The expressions of PLGF and VEGFR-1 are higher in invasive pituitary adenomas
