1转基因大麦中gfp基因的染色体位置及其表达(英文)显示文摘通过对大麦小孢子进行基因枪轰击获得 4株转绿色荧光蛋白基因 (gfp)的植株 (A、C、D、E) ,以gfp基因为探针进行荧光原位杂交 (FISH)研究转化植株中转基因插入位置和基因表达。 4个株系在染色体 7L(5HL)的不同位置都有一个插入点 ,而E株系在染色体 5S(7HS)还有第 2个插入点。所有的转基因T0 代植株都是半合子并在T1、T2代发生分离。D株系GFP未表达 ,但FISH和PCR分析表明gfp基因已成功插入其染色体。各株系在根尖和花粉中的GFP表达水平不同 :C株系在花粉表达强而在根尖表达中等 ;A株系在花粉中等表达而在根尖表达较淡 ;E株系则在根尖高表达 ,花粉中等表达。A和C株系在根尖和花粉的GFP分离都表现单位点特性 ,而E株系的根尖分离表现重叠作用 (15∶1)特征 ,但在花粉中表达GFP的频率低。PCR结果和 3个分离株系的根尖表达结果一致。D和E株系的GFP表达不正常可能和gfp基因插入位置或基因的结构有关。陈建民 Carlson A R 万建民 Kasha K J 2003Acta Genetica Sinica2003,30,8:6
2Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed.Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee 2014World Journal of Clinical Oncology2014,5,2:5
