　　Microsatellites or simple sequence repeats (SSRs) constitute a significant portion of genomes and play an important role in gene function and genome organization.The availability of a complete genome sequence for yak (Bos grunniens) has made it possible to carry out genome-wide analysis of microsatellites in this species.We analyzed the abundance and density of perfect SSRs in the yak genome.We found a total of 723,172 SSRs with 1-6 bp nucleotide motifs, indicating that about 0.47 % of the yak whole genome sequence (2.657 Gb) comprises perfect SSRs, the average length of which was 17.34 bp/Mb.

长链非编码RNA与肾细胞癌发生

长链非编码RNA(Long noncoding RNAs,lncRNAs)是一类长于200个核苷酸但不编码蛋白质的RNA,可在转录、转录后和翻译等多个层面参与基因表达调节,调节了细胞分化、凋亡和胚胎发育等多个过程,功能异常与疾病发生密切相关.已鉴定出多种癌症发生相关lncRNA,包括ANRIL、XIST、HOTAIR和KCNQ1OT1等[1],我们在肾细胞癌中检测出HOTAIR和lincRNA-p

自然选择作用引起中国南迁蒙古群体的HLA-DRB1等位基因频率适应性的变化

病原驱动的平衡选择塑造了丰富的HLA等位基因。当病原谱发生改变时，群体的HLA可能也会发生相应的改变。约700年前一支蒙古族群体从中国北方迁入中国南方的云南地区。中国南北方有着不同的病原谱，因此本文拟研究迁入云南的蒙古群体其HLA发生了什么改变，并讨论这些改变发生的原因。用基于测序的分型方法(sequence-based typing method (SBT))，对中国南北方的两个蒙古群体及其它5
