Abstract:
Cofilin1 (CFL1) is an actin-modulating protein, which belongs to the ADF/Cofilin family. Neural Wiskott-Aldrich syndrome protein (N-WASP) is the key regulator of the actin cytoskeleton, a member of Wiskott-Aldrich syndrome protein family. They have been suggested to be involved in cancer cell invasion and metastasis. In this study, the expression patterns of CFL1 and N-WASP in normal esophageal mucosa and esophageal squamous cell carcinoma (ESCC) and their correlation with clinical characteristics were investigated. Immunohistochemical staining showed that CFL1 was expressed in nuclear and cytoplasm of cancer cells. However, N-WASP was mainly found in the cytoplasm of the cancer cells. There were significant evidences that proved that CFL1 is correlated with clinicopathological factors in ESCC, such as infiltration depth, lymph node metastasis and pathological staging (P < 0.05). It is also proved that N-WASP is related to lymph node metastasis and pathological staging in ESCC (P < 0.05). Kaplan-Meier analysis showed that there was no correlation between CFL1 and N-WASP protein expression and survival (P > 0.05). Moreover, the mRNA expression of CFL1 and N-WASP was detected by quantitative real time PCR in 70 tissue specimens. The results showed that CFL1 mRNA level was over-expressed in ESCC tissue (P < 0.05), while N-WASP mRNA expression level was not different between cancerous tissues and adjacent normal esophageal mucosa (P > 0.05). Also, CFL1 mRNA expression was significantly associated with regional lymph node metastasis and pathological staging (P < 0.05). Kaplan-Meier analysis showed that there was no correlation between CFL1 and N-WASP mRNA expression and survival (P > 0.05). Our findings suggested that CFL1 and N-WASP may play an important role in the tumorigenesis of ESCC, and to be the candidate novel biomarkers for the diagnosis and prognosis of ESCC. These findings may have implications for targeted therapies in patients with ESCC.
