Abstract
The present invention provides a target sequence of an RNA virus. The target sequence is a nucleic acid sequence fragment in the gene sequence in the RNA virus containing 20-40 bases and having not less than 95% similarity to genome sequence of human or related species such as livestock and poultry. The above-mentioned target sequence of the RNA virus is selected from SEQ ID NO. 1-SEQ ID NO. 615. The present invention also relates to a primer composition for constructing the above-mentioned target sequence, biomaterials such as antisense RNA related to the above-mentioned target sequence, and related uses such as design of a vaccine lacking the target sequence. The virus fragment with the above-mentioned sequence constructed in the present invention has the function of interacting with human genomic DNA and is similar to viral miRNA. Moreover, the effect of overexpression of the target sequence of the RNA virus on the expression level of surrounding genes is verified, and a new concept that the above-mentioned target fragment is an important pathogenic substance of the RNA virus is proposed. The above-mentioned target sequence has important application value for the detection and d…
