Summary
Matrix metalloproteinases (MMPs) accelerate skin aging by degrading extracellular matrix after UV exposure. Inhibiting MMPs, especially with natural compounds, is key to mitigating skin aging and wrinkles.
Area of Science:
- Dermatology and Molecular Biology
- Biochemistry of Extracellular Matrix
- Skin Aging Research
Background:
- Skin aging involves an imbalance in extracellular matrix (ECM) molecule turnover.
- Matrix metalloproteinases (MMPs) are key enzymes driving ECM degradation.
- Limited literature summarizes skin MMPs and their inhibitors.
Purpose of the Study:
- To investigate MMP upregulation in skin cells after UV radiation exposure.
- To explore clinical applications of MMP inhibitors for skin aging.
- To compile a comprehensive list of MMP inhibitors.
Main Methods:
- Extensive literature search across academic databases (e.g., Web of Science, PubMed).
- Review and synthesis of existing research on MMPs and skin aging.
- Identification and categorization of MMP inhibitors from various sources.
Main Results:
- UV irradiation upregulates MMPs, contributing to skin aging.
- MMPs exhibit specific substrate preferences and roles in UV-induced skin damage.
- A comprehensive list of natural and synthetic MMP inhibitors was compiled.
Conclusions:
- MMPs play a significant role in UV-induced skin aging and the formation of Advanced Glycosylation End Products (AGEs).
- Inhibiting MMPs is crucial for maintaining skin youthfulness and function.
- Natural compounds from plant and animal extracts offer a promising, safer avenue for MMP inhibition and potential dietary supplements.

01:23Role of Matrix Metalloproteases in Degradation of ECM
2.3K
Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult...

Overview
In order to maintain tissue organization, many animal cells are surrounded by structural molecules that make up the extracellular matrix (ECM). Together, the molecules in the ECM maintain the structural integrity of tissue as well as the remarkable specific properties of certain tissues.
Composition of the Extracellular Matrix
The extracellular matrix (ECM) is commonly composed of ground substance, a gel-like fluid, fibrous components, and many structurally and functionally diverse...

2.8K
Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. This extracellular matrix (ECM) is composed of fibrous proteins like collagen, elastin, and fibronectin in a ground substance consisting of interstitial fluid, cell adhesion proteins, and proteoglycans. The proteoglycans form a gel-like material in the spaces between cells and provide hydration, buffering, binding, and force...

01:19The Effect of Aging on Tissues
2.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:28Phases of Wound Repair
5.9K
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...
