查询词典 y chromosome

Objective In order to improve the discrimination power and exclusion chance of polymorphic markers on chromosome Y, it is necessary to cast about for novel Y-STR loci and to develop a new method to genotype Y-SNP for forensic science.

目的 为了提高Y染色体遗传标记的个人识别能力和非父排除能力，寻找新的Y-STR和建立新一代遗传标记Y-SNP的检测方法十分必要。

Fig 1 The results of two color FISH A:Normal sperms(a sperm nucleus with a red fluorescence domain was X sperm, and with a green fluorescence domian was Y sperm);B:Numeric chromosome abnormal sperm two green fluorescence domains within the same sperm nucleus which may be classified in Y disomic sperm or diploidy sperm, in the case of hybridization with two probes, one euchromosome specific and the other sex chromosome specific, this sperm could be discriminated as disomic or diploidy sperm

图1 双色荧光原位杂交结果 A：正常精子(精子头部有1个红色荧光信号者为X精子，有1个绿色荧光信号者为Y精子)；B：染色体数目异常精子两个绿色荧光信号同在1个精子核内，可为Y双体精子或二倍体精子，若用1条常染色体探针和1条性染色体探针进行双色荧光原位杂交，可以区别该精子属Y双体精子或二倍体精子

The main aberrations of the euchromosomes was chromosome gain, including trisome, tetrasome, and polysome. The gain rates of the four euchromo-some were 84.9%, 77.5%, 63.7% and 83.2%, and the frequencies of polysome for each euchromosome were 24.6%, 34.9%, 23.4% and 31.7%, respectively. Loss of chromosome Y was observed in 61.2% of male patients. The combination of the four chromosome probes 3, 8, 10 and 20 detected 74.5% of ESCC and the combination of 3, 8, 20 and Y detected 85.0%.

发现所测常染色体在食管癌组织中均存在较高的数目畸变率，主要表现为染色体增益，包括三体、四体及多体。4条常染色体3、8、10和20号染色体增益率分别为84.9%、77.5%、63.7%和83.2%，其中多体率各为24.6%、34.9%、23.4%和31.7%。Y染色体在61.2%的男性患者表现缺失。3、8、10和20号探针联合检测食管癌的阳性率为74.5%， 3、8、20和Y染色体探针联合检测男性食管癌的阳性率为85.0%。
