- Overexpression of B7-H1 correlates with malignant cell proliferation in pancreatic cancer.
- Song X1, Liu J1, Lu Y1, Jin H2, Huang D1.Author information 1Department of General Surgery, Zhejiang Provincial People's Hospital, Hangzhou, Zhejiang 310016, P.R. China.2Biomedical Research Center, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, Hangzhou, Zhejiang 310016, P.R. China.AbstractB7-H1, a member of the B7 family of proteins, is hypothesised to play an important role in the immune escape of tumours through its binding to the PD-1 receptor on activated T and B cells. By inducing T lymphocyte apoptosis, tumour cells can suppress an effective antitumour immune response. Although the immunosuppressive effect of B7-H1 has been studied in many tumours, its other biological functions remain unclear. We previously demonstrated a high expression level of this molecule in pancreatic cancer patient samples and its antiapoptotic effect in pancreatic ductal adenocarcinoma (PDA) cells. The aim of the present study was to investigate the possible role of B7-H1 in the proliferation of PDA cells. Functional studies were performed using pancreatic cell lines that were genetically engineered to express high or low levels of B7-H1, and we found that the overexpression of B7-H1 through plasmid transfection in PDA cells promoted cell proliferation. Conversely, the short-hairpin RNA (shRNA) knockdown of B7-H1 inhibited PDA cell proliferation. Further analyses of the cell cycle and cell cycle-related molecules confirmed this result. Taken together, our results indicate that the upregulation of B7-H1 in pancreatic cancer cells promotes proliferation and accelerates carcinogenesis; these data, therefore, provide insights into the effects of B7-H1 overexpression on pancreatic tumour cells.

- Enhanced resistance to blast fungus in rice (Oryza sativa L.) by expressing the ribosome-inactivating protein alpha-momorcharin.
- Qian Q1, Huang L1, Yi R1, Wang S1, Ding Y2.Author information 1State Key Laboratory of Hybrid Rice, Department of Genetics, College of Life Sciences, Wuhan University, Wuhan 430072, Hubei Province, People's Republic of China.2State Key Laboratory of Hybrid Rice, Department of Genetics, College of Life Sciences, Wuhan University, Wuhan 430072, Hubei Province, People's Republic of China. Electronic address: yiding@whu.edu.cn.AbstractRice blast caused by Magnaporthe grisea is one of the three major diseases that seriously affect the rice production. Alpha-momorcharin (α-MC), a ribosome-inactivating protein (RIP) isolated from Momordica charantia seeds, has antifungal effects in vitro. In this study, the α-MC gene was constitutively expressed under the control of the 2×35S promoter in transgenic rice (Oryza sativa L.) using an Agrobacterium tumefaciens-mediated method. The nine transgenic plants were obtained and confirmed by PCR and RT-PCR, and the four (B2, B4, B7 and B9) of them whose copy numbers were 1, 2, 3 and 3, respectively, were shown to express the α-MC protein by Western blot. The molecular weight of α-MC in transgenic plants was approximately 38kDa larger than the purified α-MC protein (28kDa) in vitro. When the confirmed T1 generations were inoculated with a suspension of M. grisea spores for ten days, the lesions on leaves of transgenic plants were much lesser than those found on wild type (WT). According to the criteria of International Rice Research Institute standard, the mean values for morbidity and disease index numbers were 29.8% and 14.9%, respectively, which were lower than for WT. It is unclear whether RIPs could impact plant fitness and however our results suggest that the α-MC protein is an effective antifungal protein preventing rice blast in transgenic rice.

- 親和性の低いIL-2受容体はβ鎖とγ鎖からなりT細胞表面に発現している。MHC class IIと抗原複合体のTCRを介した主シグナルとB7のCD28を介した副シグナルを受けるとT細胞が活性化する。するとT細胞はCD25(α鎖)を発現し、親和性の強いIL-2受容体を形成する。IL-2はT細胞を刺激して増殖や分化を促す。 (IMM.345)
