Altered expression profile of apoptosis-related molecules correlated with clinicopathological factors in non-small-cell lung cancer.

This study was aimed to observe the expression patterns of apoptosis-related molecules in lung cancer and paired non-cancerous tissues, and to observe if there is a correlation between the expression of these apoptotic molecules and clinicopathologic parameters. Immunohistochemistry (IHC) was performed to analyze the expression level of CASP3, CASP8, CASP9, PARP1, Cleaved CASP3 (C-CASP3), Cleaved PARP1 (C-PARP1), XIAP, BIRC5 (Survivin) and BCL2 in lung cancer and paired non-cancerous tissues. We found that apoptosis-related molecules CASP3, CASP9, BCL2, BIRC5 and PARP1 are abnormally expressed in lung cancer cells and their expression were correlated with histology. BCL2, BIRC5 and PARP1 are expressed at higher levels in SCC than in non-SCC. C-PARP1 expression might be an independent prognostic factor for NSCLC. PMID: 26647102 [PubMed - in process]
