Abstract

To investigate the expression of Survivin and its relationship with the expression of Bcl-2 in sinonasal inverted papilloma (SNIP). Immunohistochemical method was used to determine the expression of Survivin and Bcl-2 in 30 cases of SNIP, 10 cases of sinonasal squamous cell carcinoma (SCC) and 10 cases of normal inferior concha tissues. Survivin was expressed in 22 of 30 (73.3%) cases of SNIP, 8 of 10 (80.0%) cases of SCC and not expressed in 10 (0%) cases of normal inferior concha tissues. Expression of Survivin was significantly higher in SNIP and SCC than in normal tissues. Bcl-2 was expressed in 9 of 10 (90.0%) cases of SCC and 2 of 10 (20.0%) cases of normal inferior concha tissues. Expression of Bcl-2 was significantly higher in SCC than in normal tissues. Bcl-2 was expressed in 14 of 30 (46.7%) cases of SNIP, higher than normal tissues. Expression of Bcl-2 was positively related to expression of Survivin. Survivin may play an important role in the pathway of progression of SNIP and SCC. It may be identified as a new therapeutic target. Bcl-2 may play a synergic role with Survivin in progression of SNIP.

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.
