To study the link between BRAFV600E status and the expression of BIM gene in papillary thyroid carcinoma( PTC) tissues and to analyze the association of these factors with clinicopathological characteristics. BRAFV600E status was determined by MASA-PCR, and qPCR was applied to detect the expression of BIM gene. Finally, the associations of these factors with clinicopathological characteristics were analysed. The rate of mutant BRAFV600E in PTC was 54. 1% , and the expression of BIM gene was lowered in BRAFV600E positive PTC tissues. Additionally, there was significant association( P < 0. 05) between BRAFV600E positiveness and raised TNM Staging (Ⅲ/ Ⅳ), and lowered BIM expression was significantly associated (P<0. 05) with the tumor size and raised TNM Staging(Ⅲ/ Ⅳ). These findings may help us to know more about the mechanism of PTC and to develop new diagnostic biomarkers or prognostic indicators of PTC.
