Abstract
AIM: To analyze the expression of protein kinase Cα (PKCα) and nuclear factor-kappa B (NF-κB) p50/p65 proteins in esophageal squamous cell carcinoma (ESCC) in Kazakh patients and to analyze their clinical significance.
METHODS: Immunohistochemistry was used to detect the expression of PKCα and NF-κB p50/p65 in 50 ESCC specimens and matched tumor-adjacent normal tissues.
RESULTS: The positive rates of PKCα and NF-κB p50/p65 proteins in ESCC were significantly higher than those in adjacent normal tissues (PKCα: 46.0% vs 8.0%; p50: 82.0% vs 48.0%; p65: 56.0% vs 36.0%, P = 1.9 × 10-5, 3.7 × 10-4 and 0.045, respectively). The expression of PKCα protein was closely correlated with ESCC differentiation (P = 0.030), p50 expression was correlated with metastasis (P = 0.042), and p65 expression was significantly correlated with differentiation and invasion (P = 0.015 and 0.042, respectively). PKCα expression had a positive correlation with p50 and p65 expression in ESCC (p50: r = 0.435, P = 4.5 × 10-6; p65: r = 0.626, P = 1 × 10-6).
CONCLUSION: The interaction of PKCα with NF-κB signal pathway may be involved in the invasion and metastasis of ESCC in Kazakh patients.
