最近的一项研究表明,食蟹猴(Macaca fascicularis)中抗逆转录病毒因子TRIM5基因衍生的同种型TRIMCyp的频率根据所检查的特定栖息地而变化很大。然而,这些发现是否真正反映了野生食蟹猴中TRIMCyp的流行率仍然不确定,因为以前的数据是从繁殖和饲养设施中的圈养猴中获得的。在这里,我们描述了野生食蟹猴中TRIM5基因的特征,发现TRIMCyp等位基因的频率与圈养猴中的频率相当。这表明,以前的结果与圈养猴子确实反映了自然的等位基因频率,繁殖和饲养设施可能不会影响TRIM5等位基因的频率。有趣的是,从菲律宾的野生猕猴的TRIMCyp的一个小的单倍型的患病率显着低于圈养的,这表明它是有利的野生猴拥有的主要单倍型的TRIMCyp。总的来说,我们的研究结果增加了我们对食蟹猴TRIMCyp的地理和遗传患病率的理解。
A recent study showed that the frequency of an antiretroviral factor TRIM5 gene-derived isoform, TRIMCyp, in cynomolgus macaques (Macaca fascicularis) varies widely according to the particular habitat examined. However, whether the findings actually reflect the prevalence of TRIMCyp in wild cynomolgus macaques is still uncertain because the previous data were obtained with captive monkeys in breeding and rearing facilities. Here, we characterized the TRIM5 gene in cynomolgus macaques captured in the wild, and found that the frequency of the TRIMCyp allele was comparable to those in captive monkeys. This suggests that the previous results with captive monkeys do indeed reflect the natural allele frequency and that breeding and rearing facilities may not affect the frequency of TRIM5 alleles. Interestingly, the prevalence of a minor haplotype of TRIMCyp in wild macaques from the Philippines was significantly lower than in captive ones, suggesting that it is advantageous for wild monkeys to possess the major haplotype of TRIMCyp. Overall, our results add to our understanding of the geographic and genetic prevalence of cynomolgus macaque TRIMCyp.
