- the present invention relates to anti-aging agents, cosmetics, wet towels and sanitary products.
- Glycation reaction, oxidation reaction, and chronic inflammatory reaction have been pointed out as the three major aging reactions of the living body. Accumulation of reactive oxygen species (ROS) resulting from these reactions is known to be the causative agent of various aging effects. . The same is true for skin cells, and it is believed that suppression of oxidation and glycation is effective in suppressing the occurrence of wrinkles, spots, dullness, and sagging.
- ROS reactive oxygen species
- Glycation is a non-enzymatic chemical reaction of amino acid residues in various proteins to produce advanced glycation end products (AGEs).
- AGEs play an important role in aging throughout the organism and are involved in a wide variety of diseases. For example, AGE concentrations in skin collagen increase with age and are higher in diabetic patients than in age-matched healthy individuals. Furthermore, intracellular AGE formation and accumulation are known to be involved in skin aging, Alzheimer's disease, hypertension, arteriosclerosis and osteoporosis.

- Fibroblasts are known to play a role in moisturizing the epidermis, and the presence of aquaporins, receptors involved in the influx of water molecules into the cells, has attracted attention.
- fibroblasts express AQP-1 and AQP-3.
- hyaluronic acid secreted from cells is effective in moisturizing the skin.
- oxidative stress actually decreased both the mRNA expression of AQP-1 and AQP-3 and the secretion of hyaluronic acid.
- Addition of VB2 or VB3 improved both AQP-1 and AQP-3 mRNA levels and hyaluronic acid secretion. The ameliorative effect was stronger when VB2 or VB3 existed before oxidative stress was applied.
- hyaluronic acid In humans, half of hyaluronic acid exists in the skin. While hyaluronic acid is reduced from the epidermis due to aging, hyaluronic acid still remains in the dermis, which leads to age-related loss of moisture, loss of elasticity, and atrophy of the skin. Using VB2 or VB3 has been shown to restore lost hyaluronic acid.
- VB2 and VB3 which are polyacid compounds that have been reported to have antibacterial and antiviral activities, are pleiotropic, and almost It also exhibited anti-glycation and antioxidant effects. Addition of VB2 or VB3 alone to cells did not alter various parameters. This indicated that both VB2 and VB3 are useful as skin anti-aging agents.

0.2mMの過酸化水素を添加した培養液で、ヒト皮膚線維芽細胞を2時間インキュベーションしたのち、PBSで洗浄除去し、通常の培地に入れ替えて培養を継続した。VB2およびVB3は、それぞれ過酸化水素を添加する前後のいずれかのタイミングで添加し、4時間共培養した。そののち、細胞または培養液を回収した。
ここで、VB2およびVB3は、1μg/mL、10μg/mL、100μg/mLおよび300μg/mLの濃度のものをそれぞれ添加した。
上記「細胞生存率の測定」に記載した手順により、ヒト皮膚線維芽細胞の処理、培養(共培養)を行い、細胞または培養液を回収した。用いたVB2、VB3の濃度、および、結果を示すグラフである図6および図7におけるサンプルの表記も上記「細胞生存率の測定」と同様である。
上記「細胞生存率の測定」に記載した手順により、ヒト皮膚線維芽細胞の処理、培養(共培養)を行い、細胞または培養液を回収した。結果を示すグラフである図8および図9におけるサンプルの表記も上記「細胞生存率の測定」と同様である。
上記「細胞生存率の測定」に記載した手順により、ヒト皮膚線維芽細胞の処理、培養(共培養)を行い、細胞または培養液を回収した。用いたVB2、VB3の濃度、および、結果を示すグラフである図10および図11におけるサンプルの表記も上記「細胞生存率の測定」と同様である。
上記のAGE受容体、ヒートショックプロテイン、アクアポリン、ヒアルロン酸およびElastinの測定に用いるqRT-PCR法について、説明する。qRT-PCR法は、得られたTotal RNA 500 ngをPCRのテンプレートとし、逆転写反応(Reverse Transcriptase;RT反応)によるcDNA合成と、定量PCRを1つの試験管内で行うことができるOne step RT-PCRをLuna Universal One-Step qRT-PCR Kitを用いて行った。
ヒト皮膚線維芽細胞は皮膚真皮に存在しながら表皮の角化細胞と並んで表皮の状態を左右する重要な細胞である。
Hsp104は凝集したタンパク質を元に戻す機能が示され、gp96は細胞内抗原提示に関与し、Hsp90は厳選されたタンパク質だけを対象に成熟を助け、Hsp70はタンパク質のフォールディングや輸送や分解を制御することで品質を管理する。また、Hsp60はミトコンドリアにおけるタンパク質をフォールディング維持、ミトコンドリア等へのタンパク質の膜透過に関与し、Hsp32はヘム分解に関与しヘム分解生成物は抗酸化作用を有する。VB2、VB3は共にAGEストレスを受けた細胞において、細胞内タンパク質の品質を保持するようなHspを誘導することが示された。
