Objective To investigate the effect of tumor necrosis factor alpha ( TNF-?) in combination with Go6976 on murine liver cancer cells (H22). Method H22 cells were divided into two groups. Each group was further divided into four subgroups. Group 1 was treated with TNF-? 0, 20, 40, 60ng/ml. Group 2 was treated with TNF-? 0, 20, 40, 60 ng/ml and Go6976 (4.6 nmol/ml). The apoptotic rate, protein kinase C alpha (PKC-?) expression and phosphorylation-PKC-? (p-PKC-?) were detected by flow cytometer and Western blotting respectively in 4 h, 8 h and 16 h. Result Treated with TNF-? (0, 20, 40, 60 ng/ml) for 4 h, the apoptotic rates of H22 cells were 2. 44% ? 0. 31 % , 1. 80% ? 0. 32% , 2. 73% ?0. 14% and 3. 05% ?0. 78% respectively, with no change on the expression of PKC-? and p-PKC-?; For 8 h, the expressions of PKC-? and p-PKC-? in H22 cells were up-regulated with increasing concentration of TNF-?; When PKC-? was inhibited with Go6976 at the same time, the apoptotic rates of cells increased significantly, being 2. 90% ?0.39%, 7.76% ?0.35%, 11.43% ?1.05% and 12.96% ?2.44% , respectively. Moreover, PKC-? and p-PKC-? were down-regulated accordingly. When H22 cells were treated with TNF-? only or combined with Go6976 for 16 h, the result was similar to that of 8 h; The apoptotic rate dropped in the group in which PKC-? was inhibited by Go6976 with TNF-? at 60 ng/ml, but the proportion of necrotic cells increased. Conclusion TNF-? up-regulates the expression of PKC-? and p-PKC-? in H22 cells. Inhibiting the activity of PKC-? significantly enhances the toxicity of TNF-? to H22 cells.

To screen and evaluate protein biomarkers for the detection of gliomas (Astrocytoma grade I-IV) from healthy individuals and gliomas from brain benign tumors by using surface enhanced laser desorption/ionization time of flight mass spectrometry (SELDI-TOF-MS) coupled with an artificial neural network (ANN) algorithm. SELDI-TOF-MS protein fingerprinting of serum from 105 brain tumor patients and healthy individuals, included 28 patients with glioma (Astrocytoma I-IV), 37 patients with brain benign tumor, and 40 age-matched healthy individuals. Two thirds of the total samples of every compared pair as training set were used to set up discriminating patterns, and one third of total samples of every compared pair as test set were used to cross-validate; simultaneously, discriminate-cluster analysis derived SPSS 10.0 software was used to compare Astrocytoma grade I-II with grade III-IV ones. An accuracy of 95.7%, sensitivity of 88.9%, specificity of 100%, positive predictive value of 90% and negative predictive value of 100% were obtained in a blinded test set comparing gliomas patients with healthy individuals; an accuracy of 86.4%, sensitivity of 88.9%, specificity of 84.6%, positive predictive value of 90% and negative predictive value of 85.7% were obtained when patient's gliomas was compared with benign brain tumor. Total accuracy of 85.7%, accuracy of grade I-II Astrocytoma was 86.7%, accuracy of III-IV Astrocytoma was 84.6% were obtained when grade I-II Astrocytoma was compared with grade III-IV ones (discriminant analysis). SELDI-TOF-MS combined with bioinformatics tools, could greatly facilitate the discovery of better biomarkers. The high sensitivity and specificity achieved by the use of selected biomarkers showed great potential application for the discrimination of gliomas patients from healthy individuals and gliomas from brain benign tumors.
