Expression and significance of NF-κB and VEGF in gastric carcinoma

AIM: To investigate the expression and clinical significance of nuclear factor-kappa B (NF-κB) and vascular endothelial growth factor (VEGF) in gastric carcinoma.

METHODS: Sixty-eight patients with gastric carcinoma were selected as experimental group, and their corresponding noncarcinoma tissues were selected as control group, and 20 normal healthy gastric tissue samples were taken as normal control group. Immunohistochemical method (SABC) was used to test the NF-κB and VEGF protein. And the clinical pathological data were statistically analyzed.

RESULTS: NF-κB and VEGF were not expressed in normal gastric tissues, but were positively expressed in control group and in study group with a significant difference detected (63.2% vs 2.9%, 76.5% vs 14.7%, both P = 0.000). Expression of NF-κB and VEGF were not correlated with the gender, age and histological type in gastric carcinoma. While the expression of NF-κB and VEGF in gastric carcinoma with TNM stage (Ⅲ + Ⅳ), lymph node metastasis, serous membrane involved, and distant metastasis were significantly higher than those of TNM stage (Ⅰ + Ⅱ), without lymph node metastasis, or without serous membrane involved, or without distant metastasis (P < 0.05), respectively. There was significantly positive correlation between NF-κB and VEGF in gastric carcinoma (r = 0.512, P = 0.000).

CONCLUSION: NF-κB and VEGF are both significantly expressed in gastric carcinoma and there is a positive correlation between them. And the possible mechanism is that NF-κB up-regulates VEGF, hence promotes the development of gastric carcinoma.

Chinese herb related molecules of cancer-cell-apoptosis: a minireview of progress between Kanglaite injection and related genes

Many kinds of Chinese herb had been confirmed to have the character of anti-tumor, clinical reports about anti-tumor effects of Chinese herb had also been found in recent years, but most of the reports were focused on the clinical treatment of effectiveness for Chinese herb, on the other hand, review about Chinese herbal related with molecules on cancer-cell-apoptosis was seldom, many scientists could not believe such kinds of clinical describes about anti-tumor effects for Chinese herb, because these describes were lack of molecular biology evidence. Kanglaite(KLT) injection is an anti-tumor new drug which extracts from Chinese medicine-coix seed with modern advanced pharmaceutical technology, it is also a new biphase extended-spectrum anticancer medicine, the food and drug administration(FDA) of United States also approved a phase II trial of KLT to test its efficacy in treating non-small-cell lung cancer. Some studies show it could inhibit some anti-apoptotic gene and activate some pro-apoptotic gene, its injection solution is one of the new anticancer medicine that can significantly inhibit a various kinds of tumor cells, so it has become the core of research that how to further explore KLT injection to promote tumor cell apoptosis by impacting on related genes. In this review, the relationship between KLT and some tumor cell apoptosis molecules had been discussed and reviewed generally.
