Given the reported side effects associated with chemotherapy and surgical resection, dietary intervention with omega-3 polyunsaturated fatty acids (PUFAs) has been postulated to be an alterative way to prevent liver cancer progression and metastasis. We studied the effects of an omega-3 PUFA, docahexaenoic acid (DHA) on COX-2 expression and the cell cycle control machinery that co-ordinately regulate the HCC cells growth. Our data showed that DHA (0-200 microM) retarded proliferation of the human metastatic HCC cell line MHCC97L dose-dependently. In addition, inhibition of cyclin A/Cdk2 interfered with S-phase progression further in agreement with the result of bivariate flow cytometric analysis which indicated that DNA synthesis time (Ts) was significantly prolonged by DHA in MHCC97L. The N-myc oncogene, the heat shock proteins Hsp27 and glucose-related protein 78 (GRP78) as well as the antioxidant enzymes superoxide dismutase may play significant roles in the cell cycle control and reduced-proliferation of MHCC97L by DHA. Our data indicated that it is imperative to develop therapeutic strategy with omega-3 PUFA that simultaneously targets COX-2 and other cell cycle regulators in hepatocarcinogenesis. This study provides novel mechanistic insights into the modulation of DHA on human hepatocarcinoma.

N-myc downstream-regulated gene 1 (NDRG1) has been reported to be a multifunctional protein associated with carcinogenesis, however, the cellular function of NDRG1 remains elusive in human cancers. Here, our proteomics profile analysis of HCC tissues with different metastatic capabilities revealed that NDRG1 was correlated with metastasis and recurrence in HCC patients after liver transplantation (LT). Immunohistochemical staining of 143 HCC patients after LT showed that NDRG1-positive expression had poor prognosis, either for shorter disease-free survival or overall survival (P < 0.001), compared with NDRG1-negative expression. Multivariate analysis confirmed NDRG1 as an independent prognostic value (P < 0.001). In addition, in vitro experiments HCC cells with small interfering RNA against NDRG1 significantly suppressed its proliferation, colony formation, invasion and migration ability. Microarray analysis revealed that NDRG1 modulated the expression of genes associated with transmembrane transporter activity, chemoattractant activity, immune response, cell adhesion and cell proliferation process. Taken together, these results suggested that NDRG1 was an important molecule in controlling HCC metastasis and thus suggested as a novel biomarker for predicting HCC recurrence after LT.
