Finally, We searched for paralogous genes appeared in the contrary differentially pathways of normal and disease status, respectively. It is very likely to find an intersectional gene between different pathways, because this intersectional gene has higher probability to associate with both these paralogous genes in different situation.

Strains M110 and M113 isolated from Aedes albopictus and Armigeres durhami, respectively, which were fatal to suckling mice at 4 days after intracerebrally inoculation and had cytopathologic effects on BHK21 cells, showed a positive reaction to dengue antibody and could be amplified Ly using flavivirus primers and dengue type-4 NS1 gene primers and dengue type-4 NS2a gene primers.

结果 从白纹伊蚊和达勒姆阿蚊中各分离到一株病毒，分别命名为M110和M113，这两株病毒对BHK21细胞能产生明显的细胞病变，脑内接种乳鼠4d左右导致乳鼠死亡。该病毒经血凝、血凝抑制和间接免疫荧光试验提示为黄病毒。分别用黄病毒属特异引物、登革4型病毒NS1和NS2a基因片段特异引物进行RT-PCR扩增、序列测定，证实为登革4型病毒。

These variations may have some effect on gene structures and gene expression, and then contribute to intraspecific phenotypic diversities.
