ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of Feiyanning Recipe's (FR) components on the microvessel density (MVD), the mRNA and protein expressions of matrix metalloproteinase-2 (MMP-2) and MMP-9 in Lewis tumors loaded in C57BL/6 mice.</p><p><b>METHODS</b>C57BL/6 Lewis lung cancer mouse model was established. Mice were randomly divided into five groups, i.e., the model group, the FR group, the qi benefiting group, the Shen-tonifying group, and the anti-cancer group. The mice were killed on the 22nd day after 21-day gastrogavage. Tumors were extracted. The MVD of Lewis tumor was detected by immunohistochemical SP method. The mRNA and protein expressions of MMP-2 and MMP-9 were measured using reverse transcription-polymerase chain reaction (RT-PCR) and SP method.</p><p><b>RESULTS</b>Compared with the model group and the qi benefiting group, the MVD was significantly reduced in the FR group, the Shen-tonifying group, and the anti-cancer group (P<0.01, P<0.05). But there was no significant difference between the qi benefiting group and the model group (P>0.05). The mRNA and protein expressions of MMP-2 in the FR group, the Shen-tonifying group, and the anti-cancer group were also significantly less than those in the model group (P<0.05, P<0.01). At the same time the expression of MMP-2 mRNA in the Shen-tonifying group and the anti-cancer group was also less than that in the qi benefiting group (P<0.05). The mRNA and protein expressions of MMP-9 in the FR group, the Shen-tonifying group, and the anti-cancer group were significantly lower than those in the model group and the qi benefiting group (P<0.05, P<0.01).</p><p><b>CONCLUSION</b>The target for Shen-tonifying and anti-cancer Chinese herbs to inhibit tumor angiogenesis might be correlated with restraining expressions of MMP-2 and MMP-9, and protecting tumor microenvironment.</p>
