- Abstract
Krűppel-like factors (KLFs), highly conserved zinc-finger proteins, play either anti- or pro-proliferation roles in different human cancers through regulating a wide range of genes' expression. Here, we investigated the expression of KLF5 in gastric cancers and its correlation with clinicopathological parameters and overall survival rates. In this study, KLF5 expression was measured by an immunohistochemical microarray assay of tissue taken from 76 surgical specimens. Higher KLF5 expression was significantly associated with lower tumor grade (P < 0.001). Nuclear staining of the KLF5 expression was significantly associated with a higher tumor grade (P = 0.000), higher clinical stage (P = 0.019), lymph node status (P = 0.016), and 2-year survival (P = 0.017). Patients with nuclear staining of KLF5 had a significantly lower disease-free survival rate compared to patients with negative nuclear staining, as defined by a log-rank test (P = 0.041). Our results revealed that KLF5 may play an oncogenetic role in gastric carcinogenesis.
