Abstract

Survivin, a member of the inhibitor of apoptosis protein family, is a potential prognostic marker and molecular target for anticancer therapies. Chromosomal regional maintenance protein‑1 (CRM‑1) mediates the nuclear export of proteins such as survivin. The aims of the present study were to compare the expression and subcellular localization of CRM‑1 in human gastric and colorectal carcinomas and to assess the association between CRM‑1 and survivin expression in these tumor types. The nuclear and cytoplasmic CRM‑1 expression rates in gastric carcinoma were 61% (42/69) and 29% (20/69), respectively, while the nuclear and cytoplasmic CRM‑1 expression rates in colorectal carcinoma were 55% (43/78) and 37% (29/78), respectively. Nuclear and cytoplasmic CRM‑1 expression was found to be significantly correlated with nuclear and cytoplasmic survivin expression in colorectal carcinoma, but not gastric carcinoma. These results indicate that CRM‑1 expression patterns differ between gastric and colorectal carcinomas and thus, we hypothesize that CRM‑1‑mediated nuclear export of survivin may be deregulated in gastric carcinoma. Therefore, CRM‑1 may exhibit different functions in gastric and colorectal carcinoma.
