The researchers have already shown in their PNAS paper that it is possible to modify a human cell line to produce the gp120 HIV protein with the correct carbohydrates attached. 研究人员已经在PNAS上的文章上指出，改造人的细胞系能使其产生携带适当糖链的gp120HIV蛋白。

The PNAS study showed that several variants in the Factor H gene significantly increase the risk of developing AMD. PNAS的研究显示因子H基因的几个突变可以*增加AMD的危险性。

As described in the PNAS paper, about one-third ( 29 percent) of people with a Factor H risk variant had not been diagnosed with AMD. 正如PNAS的一篇文章所描述的那样，大约三分之一（29%）携带因子H突变的人没有患AMD。

However, unlike most of the DNA and RNA oligonucleotides, PNAs are poorly penetrated through the cell membrane, partially due to their uncharged property. 然而，与大多数DNA和RNA寡核苷酸不同，肽核酸的透膜能力很差，部分原因是由于它们具有不带电荷的性质。

Thus, it is possible to significantly suppress nonsense mutations within target genes using antisense PNAs. 由此可见，反义PNA有可能在靶基因区域显著性抑制无义突变。
