Hypothesis

The study investigates the presence and activity of matrix metalloproteinases (MMPs) and their inhibitors in basal cell carcinoma compared to normal skin.

Conclusion

The same profile of MMPs and their inhibitors associated with stromal invasion in organ culture is also expressed in basal cell carcinomas of the skin.

Supporting Evidence

  • MMP-1 was responsible for most of the functional collagenolytic activity.
  • Gelatinolytic activity was reflected by both MMP-2 and MMP-9.
  • MMP inhibitor activity was present and reflected TIMP-1 but not TIMP-2.
  • Normal skin showed low to undetectable levels of collagenolytic and gelatinolytic activities.

Takeaway

The study looked at skin cancer samples and found that certain enzymes are more active in cancer than in normal skin.

Methodology

Tissue from 54 basal cell carcinomas was analyzed for matrix metalloproteinases and their inhibitors using functional and immunochemical procedures.
