Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.

Gene-activated matrix technology is a non-viral gene therapy strategy. Though with less impressive gene transfer efficiency than viral gene therapy, it has been used to deliver osteogenic factors locally and promote bone regeneration in long bones. The minimal safety concerns of GAM support its use in non-life-threatening conditions such as craniofacial osseous defects. However, the uses of GAM technology in intramembranous bone are largely unexplored.

Majority of acute leukemias in infant, either acute lymphoblastic leukemia or acute myeloblastic leukemia, posses a chromosomal translocation affecting the 11q23 chromosome region which specifically inoles the mixed-lineage leukemia gene.1-3 Most pediatric leukemias with MLL rearrangement clearly hae a remarkably short latency.1,4 MLL gene rearrangement is also associated with secondary leukemias of patients preiously treated with the topoisomerase II inhibitors.4 The latency of these secondary leukemias is similarly ery short.4 Of note, the concordance rate of leukemia with MLL rearrangement in infant monozygotic twins approximates to 100%,1,4 and identical breakpoint in the MLL gene was shared in these pairs of identical twin infants with concordant ALL.1,4 Moreoer, the unique and clonotypic MLL fusion gene was detectable in neonatal blood spots for Guthrie cards from non-twined indiiduals who subsequently deeloped ALL.1,4 These obserations indicate not only that MLL fusion is generated in utero but also that MLL fusion proteins could be capable of inducing leukemic transformation with few, if any, secondary mutations.2,3,4 Greaes et al speculate that an MLL fusion protein somehow promotes rapid transition to full-blown disease in patients ia ery rapid clonal expansion, genetic instability, or inhibition of DNA damage repair.4 In general, for clonal expansion of malignancies, tumor cells often hae acquired strategies that escape immune sureillance of the hosts.5,6 Immune escape mechanisms also contribute to the failure of graft-ersus-leukemia effect after allogeneic hematopoietic stem cell transplantation.7 Therefore, leukemia cells could acquire some immune escape mechanisms during leukemogenesis.
