They are characterized by excessive dermal deposition of thick, hyalinized collagen bundles
resulting from an imbalance between the production and degradation of extracellular matrix
(ECM) components. Matrix metalloproteinases (MMPs) and tissue inhibitors of
metalloproteinases (TIMPs) are two important regulators of ECM degradation and
remodeling. To evaluate the role played by knockdown of TIMPs in keloid formation, we …
