NS2 and NS3 are two post-transcriptional gene silencing suppressors that are encoded by Rice stripe virus. Gene silencing suppressors are always related to the pathogenicity of viruses. In this study, the cDNA of NS2 and NS3 were recombined by overlapping PCR assays, ligated to the RNAi vector, and inserted into the PXQ expression vector using Pst I; the expressed vector was transferred into calluses induced from seeds of the japonica rice cultivar, 'Nipponbare', using an Agrobacterium-mediated method. Thirty-one T0 transgenic plants were selected by G418 screening. PCR and southern blot analyses confirmed that the target gene was transformed into transgenic rice successfully, and different transgenic plants contained various copies of the gene. The disease resistance assay revealed that T0 transgenic rice had a delayed onset of RSV for approximately 10-20 d, and the accumulation of virus in the transgenic plants was reduced by 30%-50%. This was related to the delayed onset of disease.

The P53 gene has the important functions including induction of apoptosis, regulation of cell cycle, repair of DNA damage. The mutation of the P53 gene exists in more than 50% of human tumors and 13% of hematological malignancies. The P53 gene abnormality is closely related with the clinical course and prognosis of leukemia. The P73 or P63 gene, the member of the P53 family not only possesses similar to P53 activity of inducing apoptosis, activating transcription, but also plays different biological effects according to protein structural diversity, and even antagonises the function of the P53 gene. Researchers found that P73 or P63 gene also has the dual characteristics of the tumor suppressor and oncogene, and shows different expression and function in different types, different stages of leukemia. In this article, P53 family (P53, P73, P63) gene structure, biological function and the relationship of the three genes with the course, prognostic outcome, treatment and other clinical features of the leukemia are reviewed.

To observe the proliferation of T lymphocytes stimulated by CML and AML cells which were induced by rhGM-CSF and rhIL-4, and the secretion of IFN-gamma from proliferated T lymphocytes, the expression of CD80, CD86 and HLA-DR on CML and AML cells induced by GM-CSF and IL-4 was assayed by flow cytometry in vitro. Then one-way mixed lymphocyte reaction was carried out, with induced leukemia cells as stimulating cells and auto-T lymphocytes as reactive cells. The secretion of IFN-gamma from T lymphocytes was determined by double antibody sandwich ELISA. The results showed that GM-CSF and IL-4 significantly upregulated the expression of CD80, CD86 and HLA-DR on CML cells and CD80 and CD86 on AML cells, which could stimulate the T lymphocyte proliferation and high secretion of IFN-gamma (in CML group) of autologous T lymphocytes. It is concluded that the CML and AML cells induced by GM-CSF and IL-4 have the ability to present tumor specific antigen to auto-T lymphocyte.
