Caveolin-1 (CAV-1) has been reported to play an important role in the development of a variety of human cancers. CAV-1 expression is revealed to be reduced or absent in the malignant tumor cells of small cell lung cancers (SCLC). This study was performed to investigate the influences of the stable expression of CAV-1 on the metastasis and proliferation of SCLC in vitro. The wild-type CAV-1 gene was successfully transfected into the NCI-H446 cells and was stably expressed in the NCI-H446 cells. The effects of CAV-1 on the morphology, proliferation, and metastasis potential for NCI-H446 cell were evaluated by crystal violet staining, MTT analysis, transwell assay, and scratch wound assay, respectively. Western blot and gelatin zymography were used to examine the expression changes of the metastasis-related MMP-3 and E-cadherin. Stable expression of CVA-1 was observed in the H446-CAV-1 cells, which enlarged the cell shape with filopodia. The proliferation of H446-CAV-1 was inhibited, while its migration and invasion abilities were promoted in vitro. The re-expression of CAV-1 reduced the expression of E-cadherin, while it increased the protein expression and enzyme activity of MMP-3. Taken together, the cellular proliferation of the NCI-H446 could be inhibited by the re-expression of CAV-1. CAV-1 might increase the cell metastasis potential through the interaction with E-cadherin and MMP-3 genes. These in vitro findings confirm the involvement of CAV-1 in the proliferation and metastasis of SCLC.

Periodontitis is commonly observed in dogs. In human medicine, it is well documented that matrix metalloproteinases (MMPs) are involved in the destruction of the periodontium. Therefore, the aim of this prospective study was to investigate the impact of MMPs and their inhibitors, the TIMPs (tissue inhibitors of metalloproteinases), on canine periodontitis. The oral cavities of 57 dogs were examined clinically and radiologically. Gingival biopsies were obtained from the examined dogs and histologically analysed via haematoxylin and eosin stained sections. Immunohistological detection of MMP-2, MMP-3, MMP-8 and MMP-9 as well as TIMP-1 and TIMP-2 was performed by the avidin-biotin peroxidase complex technique. All sections were evaluated by light microscopy. Statistically significant positive correlations were detected between the histologically verified degree of inflammation and the expression of MMP-2, MMP-3, MMP-8 and MMP-9 as well as between changes in collagen fibre content and the occurrence of MMP-2, MMP-8 and MMP-9. Concerning TIMP-1 and TIMP-2, non-significant, generally negative correlations were observed. In summary, in canine periodontitis, an increased expression of the above mentioned MMPs and a tendentially decreased expression of TIMPs are present. In conclusion, in canine periodontitis, a MMP-TIMP imbalance is suggestive of contributing to the destruction of the periodontium.
