Outline of Final Research Achievements

We previously reported that patients with lung adenocarcinomas with KRAS gene mutations and strong proliferating activity had poorer outcomes and some S100 molecules were up-regulated by the oncogenic KRAS. The present study examined surgically resected primary lung adenocarcinomas for the expression of some S100 proteins, and analyzed the potential relationships between their levels and clinicopathologic factors. The results demonstrated that S100A11 expression levels were significantly higher in adenocarcinomas with KRAS mutations and strong proliferating activity. The results suggest that S100A11 plays a role in tumor progression, particularly in lung adenocarcinomas with KRAS mutations and strong proliferating activity.
