SCREENING BRAIN DNA FOR HTLV-1 PROVIRAL SEQUENCES USING PCR AMPLIFICATION

聚合酶链反应（PCR）扩增已用于鉴定 逆转录病毒样序列在多发性硬化患者和 非神经系统控制患者。 利用PCR技术鉴定新的 内源性逆转录病毒样序列在人脑DNA，我们现在 定义其组织分布和转录活性。基因组 从12例尸检的脑组织中提取DNA， 硬化和8个没有MS。PCR扩增的DNA， 进行，并使用克隆序列的放射性标记片段， 探针DNA与来自不同人体器官的RNA互补。，以及 从各种动物。 PCR扩增与MS无相关性 从PCR扩增产物中克隆到了DNA插入片段 与先前描述的序列不同，并且最有可能代表 内源性DNA序列。

Polymerase chain reaction (PCR) amplification has been used to identify retrovirus-like sequences in both multiple sclerosis patients and non-neurologic control patients. Having used PCR to identify novel endogenous retrovirus-like sequence in human brain DNA, we are now defining its tissue distribution and transcriptional activity. Genomic DNA was extracted from 12 autopsied brains patients with multiple sclerosis and from 8 without MS. PCR amplification of the DNA was performed, and radiolabeled fragments of cloned sequences were used to probe DNA complementary to RNA from different human organs., as well as from various animals. No correlation between PCR amplification and MS was found. The DNA insert cloned from PCR amplification products differed from a previously described sequence, and most likely represents an endogenous DNA sequence.
