Matrix Metalloproteinases (MMPs) are a family of zinc-dependent endopeptidases that are responsible for the breakdown and remodeling of the extracellular matrix (ECM) and basal lamina. While essential for normal physiological processes like tissue morphogenesis, wound healing, and angiogenesis, their dysregulated activity is implicated in various pathologies, including chronic inflammation, cancer metastasis, and age-related tissue degradation. They are key players in the turnover of structural proteins.
Origin
The study of these enzymes emerged from research into connective tissue biology and cancer invasion, where their role in degrading the tissue scaffold was first identified. Their nomenclature reflects their function: degrading the matrix and requiring a metal (zinc) for activity.
Mechanism
MMPs are secreted as inactive pro-enzymes and require activation, often by other proteinases, to become functionally capable of cleaving ECM components such as collagen, elastin, and fibronectin. Hormones and inflammatory cytokines act as potent regulators, either inducing the expression of specific MMPs or modulating the activity of their natural inhibitors, known as Tissue Inhibitors of Metalloproteinases (TIMPs). An imbalance favoring MMP activity leads to pathological breakdown of healthy tissue, notably in skin aging and joint disease.
Initiating hormone therapy in early menopause supports cardiovascular health by preserving arterial function, a window of opportunity that narrows with time.
Lifestyle choices provide the fundamental resources and metabolic efficiency required for optimized hormones to successfully orchestrate dermal regeneration.
Lifestyle factors like diet and exercise amplify HRT's effects by providing the building blocks and metabolic support for hormonally-driven skin repair.
