Description

Application of gorse extract
Technical Field
The invention belongs to the field of plant extraction and daily chemicals, and particularly relates to an application of a gorse extract.
Background
The skin covers the whole human body surface and is in direct contact with the external environment, so that the mirror not only protects the body from being damaged by various external factors, but also reflects the health state of the body. The skin is composed of epidermis, dermis, and subcutaneous tissue, and contains skin appendages, abundant nerves, blood vessels, lymphatic vessels, and muscles. The connecting area of the dermis and the epidermis is called as a basement membrane zone, the basement membrane is a supporting pad of epithelial cells, has supporting and connecting effects between epithelial cell tissues and connective tissues, and is also a semipermeable membrane with material permeability, so that the material exchange is facilitated. The basement membrane not only serves as a layer of structural model for supporting epidermal cells, but also serves as a selective passing barrier of cells, prevents connective tissue cells from contacting epithelial cells on the basement membrane, and allows lymphocytes, macrophages and neuronal synapses to pass through; many vital phenomena such as cell morphology, cell polarity, cell metabolism, plasma membrane protein distribution, cell survival, cell proliferation and differentiation, and cell migration are closely related to the basement membrane.
The dermis is composed of cells and extracellular matrix, fibroblasts are main cells of the dermis, and the normal proliferation and differentiation of the fibroblasts maintain the structure of the dermis of the skin to form a normal structure and physiological function; extracellular matrix is a kind of macromolecular substance synthesized and secreted by cells and interacting around the cells, and many life phenomena such as proliferation and differentiation of cells, cell migration and the like are closely related to the extracellular matrix. The extracellular matrix is composed of four major classes of molecules: collagen, elastin, glycoprotein and proteoglycan. The extracellular matrix is finely and skillfully entangled and interwoven through different molecules to form various exquisite three-dimensional structures, so that the skin is endowed with elasticity and tensile strength, and looks plump and full of vitality.
The longevity gene is a gene capable of keeping active for a long time, and can greatly improve the health of organisms and prolong the life of the organisms. When a person encounters severe cold, heat or water and food deficient environments, these genes can activate the self-defense system in the human body, making the cell repair capacity powerful.
SIRT1 (sirtuin 1): one of the famous longevity genes. SIRT1 is a highly conserved protein deacetylase, is involved in regulating longevity caused by energy restriction, is called a longevity gene, has complex physiological actions, and is involved in regulating glycolipid metabolism, inflammation, oxidative stress, cell senescence, apoptosis and the like.
The HBEGF (heparin binding EGF like growth factor) gene encodes a synthetic heparin binding epidermal growth factor, which is an EGF family member that binds to and activates EGF receptors. hbegf plays a key role in pathological and physiological processes, including cancer. After the skin part of the human body is damaged, the epidermal growth factor is produced, the proliferation and the homing of cells (comprising keratinocytes, dermal cells and basement membrane cells) are promoted, and the healing of skin wounds is promoted. The up-regulation of the gene expression is helpful for promoting the repair of skin and delaying skin aging.
The col4 alpha 1 (collagen type IV alpha 1 chain) gene codes and synthesizes type IV collagen alpha 1 chain, the type IV collagen is the main component forming basement membrane, the up-regulation of the gene expression can promote the integrity of the basement membrane (also called as dermoepidermal junction, DEJ) and delay skin aging.
The IGF1 (insulin like growth factor 1) gene encodes a synthetic insulin-like growth factor 1, a protein similar in function and structure to insulin, a member of a family of proteins involved in the regulation of growth and development. Insulin-like growth factor 1 promotes keratinocyte migration and re-epithelialization of the wound surface.
The ELN (elastin) gene encodes synthetic elastin, which is the main component of elastic fibers (elastic fibers), and is rich in hydrophobic amino acids such as glycine and proline, and elastin molecules are cross-linked with each other through covalent bonds between lysine residues, and the formed cross-linked network can generate elasticity through configuration change. Elastin is an important extracellular matrix in skin and is closely related to dermal aging, which is a ring of importance in causing skin aging. Elastin acts as a rubber band in the skin, allowing the skin to stretch and fold, and functions like a spring in a mattress to maintain and support the elasticity of the skin. Therefore, elastin plays an important role in maintaining skin elasticity.
Therefore, the research on how to improve the expression of genes related to key parts and functions of the skin has important significance on improving the skin repair capacity, keeping the structural stability and delaying the skin aging.
