In order to reveal clearly the genetic character of the dwarfing polish wheat, artificial crossing, cytological and morphological studies were carried out in present study. In addition, the chromosomal location of dwarfing and long glume character of dwarfing polish wheat was studied by means of Langdon monosomic analysis.

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.

绪论 绝大多数的婴儿白血病,不管是急性淋巴性白血病或是急性骨髓性白血病,在染色体11q23部位有染色体易位的情况;这个部位的染色体易位牵连了混合谱系白血病基因。大多数具有MLL基因重排的儿童白血病潜伏期明显短很多。MLL基因重排也和经拓扑异构酶II抑制剂治疗后的继发性白血病有关。这些继发性白血病的潜伏期类似地都非常的短。很重要的是,单卵双胞胎婴儿同时患有或同时免于MLL基因重排阳性的白血病的一致性接近100%;并且同样患有ALL的同卵双胞胎的MLL基因的断裂点是一致的。而且,这种独特的克隆特异性的MLL融合基因能够从那些得ALL的非双生个体出生时的血斑标本中检测到。这些发现表明MLL融合基因产生在胎儿还在子宫的是后,而且MLL融合蛋白能过和其他的基因突变一起诱导白血病的产生。Greaes 等推测MLL融合蛋白在某种情况下同过快速克隆增殖,遗传的不稳定性或是DNA损伤修复的抑制促使疾病迅速地全面爆发。恶性肿瘤细胞的克隆增殖通常已经获得了逃避机体免疫监视的能力。免疫逃避机制也归因于异体外周血干细胞移植后移植物抗白血病作用的失效。所以,白血病细胞在白血病的产生过程中可能获得了某些免疫逃脱机制。

Formation of mating pairs, nicking of the F oriT sequence, and transfer of the 5' end of a single strand of F DNA proceed as in transfer of the F plasmid. Therefore, Part of the plasmid is transferred first, Chromosomal genes are transferred next, and the rest of the plasmid is transferred last.

雌雄菌的交配、F质粒oriT处缺口的形成、以及由单链F DNA5'末端开始转移的过程都与F质粒的转移相同,因此,首先转移的是部分质粒片段,其次是染色体基因,剩余的质粒片段最后被转移。

There were some characteristic sequences flanking the genomic breakpoints of SYT, SSX1 and SSX2. These sequences included Alu sequences, Translin recognition sequences, topoisomerase Ⅱ recognition sites and palindromic sequences. These sequences are speculative to be associated with chromosomal translocation of synovial sarcoma.
