dc.description.abstractMitochondrial transcription factor A (mtTFA) plays a crucial role in both the transcription and maintenance of mitochondrial DNA. A high expression of mtTFA has been demonstrated in several solid tumors, and is closely associated with cancer cell survival/apoptosis and growth. However, its expression pattern in pancreatic ductal adenocarcinoma (PAC) remains to be elucidated. Additionally, our groups have recently revealed that a subset of apoptosis-related genes is strongly regulated by mtTFA, and that two putative mtTFA binding sites are present in the promoter region of the survivin gene, which is a member of the inhibitorof-apoptosis protein family. We therefore investigated the correlation of the immunohistochemical mtTFA expression and the survivin index with various clinicopathological variables and the prognosis, using 70 paraffin-embedded tumor samples from patients with surgically-resected PAC. The mtTFA expression or survivin index was considered to be strong or high when ≥30% or 10% of the PAC cells showed positive staining, respectively. Strong mtTFA expression and/or a high survivin index was revealed to have a significant relationship to a pathologically high tumor grading and advanced tumor stage. Moreover, mtTFA showed significantly high co-expression with survivin. Univariate and multivariate analyses demonstrated that both the strong mtTFA expression and high survivin index groups had significantly shorter survival rates, especially within the first two years postoperatively. The combination of strong mtTFA expression and a high survivin index may predict a poor prognosis in patients with PAC, and these new biomarkers might offer useful information for the early clinical management.es
