Ozaki H, Yu AY, Della N,Ozaki K,Luna JD,Yamada H,Hackett SF,Okamoto N,Zack DJ,Semenza GL,Campochiaro PA. Hypoxia inducible factor-1alpha is increased in ischemic retina: temporal and spatial correlation with VEGF expression.

在本实验中，正常组视网膜未见明显HIF-1α蛋白阳性表达，说明在常氧条件下， HIF-1α由结构中的氧依赖降解结构域控制，并通过泛素-蛋白酶体途径迅速降解[11]。

SW480 and SW620 cells were also used to study the gene regulation with high carbohydrate intake, where it was shown that during glycolysis eight genes, HK1 (nuclear gene encoding mitochondrial protein, transcript variant 1), GPI, GAPD (glyceraldehyde-3-phosphate dehydrogenase), PGK1 (phosphoglycerate kinase 1), PGK2 (phosphoglycerate kinase 2), ENO2 (enolase 2), PKM2 (pyruvate kinase, muscle, transcript variant 2) and GLUT1 (facilitated glucose transporter, member 1) are over-expressed. In our study, we also found that during hypoxia of cancer tissues the resulting up-regulation of HIF-2α(hypoxia-inducible factor 2, alpha subunit) would in turn up-regulate the GLU1 gene, further activating glycolysis.

另一方面，在高碳水化合物的调控研究上，吾人也利用SW480和SW620细胞株分析证实醣解水解活化过程中，其六碳醣激酶-1(HK1)、葡萄糖磷酸异构酶、3-磷酸甘油醛脱氢酶、磷酸甘油酸激酶-1(PGK1)、磷酸甘油酸激酶-2(PGK2)、烯醇酶-2(ENO2)、丙酮酸激酶-2(PKM2)以及葡萄糖输送蛋白-1(GLUT1)等共有8个基因是连续上升的过度表现；此外，吾人也发现当癌细胞在缺氧的组织中，其缺氧转录子-2α基因(HIF-2α)表现上升后，会活化GLU1基因上升，进一步活化醣解代谢的进行。

The differences in photooxidation sensitivity between the inducible CAM expressing plant and the constitutive CAM plant were discussed.

讨论了出现这种光氧化敏感性差别的可能原因。

Pokeweed antiviral protein belongs to Ribosome-inactive Proteins. PAP has potent antiviral activity against many plant virus. pT1 was used as the template to amplify the deleted mutant PAP gene (N-deleted and N-,C-deIeted) by PCR and then the two genes were cloned into expression vector. Different IPTG-inducible expression vector containing different deleted mutant PAP gene was constructed and transferred into E.coli strain BL21 (DE3)-plysS.

美洲商陆抗病毒蛋白是一类能很好的抑制植物病毒的蛋白，很早就有报道低剂量的商陆叶片粗粉末就能明显的抑制TMV在菜豆叶片上局部枯斑的形成，PAP缓释剂也已用于病毒病的防治工作，但美洲商陆抗病毒蛋白属于核糖体失活蛋白，它对生长的细胞会有一定的毒性。
