AIM: To investigate the synergistic induction of apoptosis in rhabdomyosarcoma cells by the combination of TRAIL or TRAIL gene with cisplatin. METHODS: Rhabdomyosarcoma cells were treated with TRAIL, Ad/GT-TRAIL, cisplatin, respectively or the combination for 3 days. The cytotoxicity was observed by MTT assay. The apoptotic rates and the expression rates of Fas protein were measured by flow cytometry (FCM). The expression of cFLIP mRNA was determined by RT-PCR. RESULTS: Rhabdomyosarcoma cells were treated with Ad/ GT-TRAIL and TRAIL (100.0 μg/L), the cytotoxicity index were 52.5% and 43.5%, the percentage of apoptotic cells were 12.95% and 10.26%, respectively. Combined with cisplatin, the cytotoxicity index and the percentage of apoptotic cells were increased significantly (P<0.05). The expression of Fas protein in rhabdomyosarcoma cells was up-regulated and the expression of cFLIP was down-regulated with cisplatin, which were paralleled by the apoptotic rates. CONCLUSION: Combinatiion of Ad/GT-TRAIL or TRAIL and cisplatin has synergistic apoptosis-inducing effects on rhabdomyosacoma cells. 相似文献

在室温条件下,用不同浓度(0,0.005%,0.2%,0.4%,0.8%)秋水仙素溶液分别处理露地黄瓜品种CU901干种子和萌动种子,观察秋水仙素对其生长发育的影响及其诱变效应。试验结果表明,以0.8%的秋水仙素液浸泡CU901萌动种子4h的诱变效果最好,染色体加倍率可达到7.27%。与原二倍体相比,同源四倍体的萌芽率降低,侧枝数减少,节间变短、变细,叶柄变短、变细,叶片变厚且颜色明显加深,叶面积增大,花器变大,果形指数减小,且秋水仙素浓度越高,效果越明显。四倍体花粉粒的大小不一,多数畸形,可染率显著降低。 相似文献

灵芝品种子实体多糖和三萜含量分析与评价 总被引:2,自引:0,他引:2
为了选育加工专用型灵芝品种,以灵芝多糖和三萜含量为评价指标,对12个灵芝品种的子实体多糖和三萜含量进行了分析评价.结果表明,不同灵芝菌株的子实体在多糖和三萜含量上存在着一定的差异,其中多糖以薄树灵芝、日本红芝、仙芝、京大、树舌灵芝含量高,三萜含量却以京大、赤芝05、惠州、信州、树舌灵芝、松杉灵芝、日本红芝含量高,并且二者的含量不存在显著的相关性,这为选育灵芝多糖、灵芝三萜含量均高,并适合精深加工专用的灵芝品种提供了理论依据. 相似文献

The effects of combinations of salinity (no salt, 2000 p.p.m. or 4000 p.p.m. of CaCl2 and NaCl, 1:1) and water table (30 cm, 60 cm or 90 cm from the soil surface), on the vegetative growth and tolerance of ‘Golden Japanese’ plum and ‘Mit Ghamre’ and ‘Balady’ peaches were studied. The plants were grown in lysimeters. The growth of the trunk, total shoot length, the increase in shoot length per cm and the fresh weight of top, root and total plant were reduced with increasing salinity of the irrigation water. The effect was accentuated when the plants were maintained at high water table level. The salinity treatments resulted in the death of 43%, 73% and 76% of the plants in the plum, and the ‘Mit Ghamre’ and ‘Balady’ peaches, respectively, indicating that the plum is more tolerant to salinity than the peach. The plants of the salinity treatments showed various symptoms of salt injury, such as leaf burn, defoliation, shoot die-back and finally death. In the peaches, salt injury started to occur in the first growing-season, whereas the salt injury appeared in the plum in the second growing-season. The symptoms were more pronounced in the 4000 p.p.m. treatment than in the 2000 p.p.m. treatment and were more pronounced at the high water table level. The salinity level was the predominant factor and the effect of the water table on the vegetative growth diminished with increase in the salinity level of the irrigation water. 相似文献

西瓜化感作用及其化感物质成分分析 总被引:1,自引:0,他引:1
以早佳84-24为试材,研究了西瓜根、茎叶以及根系分泌物的化感效应,并对西瓜根、茎叶和根系分泌物中的化感物质进行了GC-MS检测。结果表明:西瓜根、茎叶水浸提液浓度为2.5 g?L-1时,促进西瓜种子发芽和幼苗生长|在浓度大于5.0 g?L-1时,表现为抑制作用,且随着浓度的增加,抑制作用增强|同一浓度时,西瓜茎叶水浸提液对西瓜种子发芽和幼苗生长的抑制作用大于根系水浸提液。西瓜根系分泌物浓度在2.5 μL?L-1时,促进西瓜种子发芽和幼苗生长|浓度为5.0 μL?L-1时,也开始表现为抑制作用。表明西瓜根、茎叶和根系分泌物对西瓜种子发芽和幼苗生长均呈现出低促高抑的规律。在西瓜根、茎叶和根系分泌物中共检测出32种化学物质,其中酯类化学物质最多,有14种|在西瓜根中检测到14种化学物质,茎叶中检测到19种,根系分泌物中检测到22种,其中一些曾被报道为化感物质,说明西瓜不同组织中化感物质的种类与含量不同,化感作用强度也不同。 相似文献
