It’s well recognized that X-linked inhibitor of apoptosis (XIAP) was the most potent caspase inhibitor (CASPs inhibitor) and second mitochondria-derived activator of caspase (DIABLO or Smac; HGNC21528) was the antagonist of XIAP.
X-linked inhibitor of apoptosis positive nuclear labeling is an independent prognostic biomarker of breast invasive ductal carcinoma.
- Experiments in vitro identified that down regulation of XIAP expression or applying DIABLO mimics could sensitize breast cancer cells to chemotherapeutics and promote apoptosis.
- However, expression status and biologic or prognostic significance of XIAP/Smac in breast invasive ductal carcinoma (IDC) were not clear.
- Disturbed balance of expression between XIAP and Smac probably contributed to carcinogenesis and XIAP positive nuclear labeling was a new independent prognostic biomarker of breast IDC.
