Abstract:
Objective To detect the expressions of BMPR Ⅰa of BMPs/BMPR/Smads signaling transduction pathway in human brain glioma ,to research the role of its in tumorigenesis and progression of brain glioma and its correlation to clinical pathology . Methods The mRNA and protein expressions of BMPR Ⅰa was detected in 20 normal brain tissues and 40 samples with human glioma by RT-PCR and SABC immunohistochemical methods ,repectively ,and analyzed the correlation with the patient′s age ,gender and pathological grade .Results Compared with normal brain tissues ,BMPR Ⅰa mRNA and protein expressions in human glioma were reduced significantly ,especially in Ⅲ and Ⅳ stage tumor tissues .The difference was not related with the patient′s age and gender .Conclusion In progression of glioma ,BMPR Ⅰa may play a role in restraining ,and has nothing to do with age and sex .
