The case of addition is shown as a relative value (ΔΔCt method) with 1.00. 図2は、実験1において各濃度(0.10重量%、0.50重量%)の金銀花エキスを添加した場合の正常ヒト表皮角化細胞におけるTIPARP発現量を、陰性対照(エタノールのみ)を添加した場合を1.00とした相対値(ΔΔCt法)として示す。FIG. 2 shows the expression level of TIPARP in normal human epidermal keratinized cells when each concentration (0.10% by weight, 0.50% by weight) of gold and silver flower extract was added in Experiment 1, and the case where a negative control (ethanol only) was added. It is shown as a relative value (ΔΔCt method) set to 1.00.

本発明はアルテロモナス発酵エキス及び/又は金銀花エキスを有効成分として含有するTIPARP産生促進剤を提供する。TIPARP(TCDD(2,3,7,8-tetrachlorodibenzo-p-dioxin)-inducible poly-ADP-ribose polymerase)は、PARP7、ARTD14としても知られ、モノADPリボシルトランスフェラーゼ(mono-ADP-ribosyltransferases)およびアリール炭化水素受容体(AhR:Aryl hydrocarbon Receptor)の転写抑制因子である。TIPARPは、免疫、幹細胞の多能性、転写因子の調節等における重要な調節因子であり、TIPARPノックダウンにより肝臓脂肪が蓄積することや、乳癌においてTIPARPのメチル化が起こりその発現が減少することが知られている(非特許文献1、2)。本発明によりTIPARPの産生が促進できれば、免疫の改善、TIPARP減少に起因する各種疾患や状態を予防・改善することが期待される。 The present invention provides a TIPARP production promoter containing an Alteromonas fermented extract and / or a honeysuckle extract as an active ingredient. TIPARP (TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) -inducible poly-ADP-ribose polymerase), also known as PARP7, ARTD14, is mono-ADP-ribosyltransferases and aryl. It is a transcriptional repressor of the hydrocarbon receptor (AhR). TIPARP is an important regulator in immunity, pluripotency of stem cells, regulation of transcription factors, etc., and the accumulation of liver fat by TIPARP knockdown and the methylation of TIPARP in breast cancer, which reduces its expression. Is known (Non-Patent Documents 1 and 2). If the production of TIPARP can be promoted by the present invention, it is expected to improve immunity and prevent / ameliorate various diseases and conditions caused by a decrease in TIPARP.

本発明のTIPARP産生促進剤の一態様では、TIPARP産生を促進することによりAhRの活性化を抑制する。AhRは、薬物や環境中の危険因子による毒性作用等を媒介する転写因子である。AhRは、芳香族炭化水素類やダイオキシン類と結合し異物代謝を誘導すること、成長因子、抗酸化因子、炎症物質などを誘導すること等が報告されている(非特許文献3)。皮膚では、AhRの活性化により、活性酸素の発生、くすみ、メラニン産生といった悪影響を及ぼすことが知られており、これらの悪影響は紫外線の蓄積により悪化する。本発明のようなTIPARP産生促進を利用することにより、AhRの活性化を抑制し、AhRの活性化に起因する上述のような各種疾患や状態を予防・改善することが期待される。 In one aspect of the TIPARP production promoter of the present invention, the activation of AhR is suppressed by promoting TIPARP production. AhR is a transcription factor that mediates toxic effects by drugs and risk factors in the environment. It has been reported that AhR binds to aromatic hydrocarbons and dioxins to induce foreign body metabolism, induces growth factors, antioxidant factors, inflammatory substances, and the like (Non-Patent Document 3). In the skin, activation of AhR is known to have adverse effects such as generation of active oxygen, dullness, and melanin production, and these adverse effects are exacerbated by the accumulation of ultraviolet rays. By utilizing the promotion of TIPARP production as in the present invention, it is expected to suppress the activation of AhR and prevent / ameliorate various diseases and conditions as described above caused by the activation of AhR.

TIPARPの産生促進とは、例えばTIPARP遺伝子の発現はTIPARPタンパク質量を増加させること、例えば何も付与していない状態(コントロール)に比べて、TIPARP産生促進剤を付与した場合にTIPARP遺伝子の発現又はTIPARPタンパク質量が増加していることを意味し得る。本発明におけるTIPARPの産生促進とは、例えば何も付与していない状態(コントロール)に比べて、TIPARP産生促進剤を付与した場合に、TIPARP遺伝子の発現又はTIPARPタンパク質量が、例えば5%以上、10%以上、20%以上、30%以上、40%以上、50%以上、60%以、70%以上、80%以上、90%以上、100%以上、200%以上、300%以上、400%以上、又は500%以上亢進していることを意味し得る。TIPARP遺伝子の発現量は、任意の公知技術により求めることができる。 The promotion of TIPARP production means that, for example, the expression of the TIPARP gene increases the amount of TIPARP protein, for example, the expression of the TIPARP gene or the expression of the TIPARP gene when the TIPARP production promoting agent is given as compared with the state (control) in which nothing is given. It can mean that the amount of TIPARP protein is increased. The promotion of TIPARP production in the present invention means that the expression of the TIPARP gene or the amount of TIPARP protein is, for example, 5% or more when the TIPARP production promoting agent is given, as compared with the state (control) in which nothing is given. 10% or more, 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, 90% or more, 100% or more, 200% or more, 300% or more, 400% It can mean that it is increased by 500% or more. The expression level of the TIPARP gene can be determined by any known technique.

このようなTIPARP産生促進作用は、in vivo、in vitro、ex vivo等を含む各種方法で測定できる。例えば、被験物質を肝細胞、乳腺細胞、脂肪細胞、皮膚細胞、といった細胞に投与し、その細胞におけるTIPARPのmRNA発現量をqPCRなどの方法により求める、あるいはタンパク量をウエスタンブロッティング等の方法により求める等により決定できる。しかしながら測定方法は上記方法に限定されず、他の任意の方法を採用してもよい。例えば、ヒト等の動物に投与した後に肝臓、乳房、脂肪、皮膚組織/モデルなどの試料におけるTIPARPのmRNA発現量又はTIPARPタンパク質量を測定するといったin vivoやex vivoの方法を採用してもよい。 Such TIPARP production promoting action can be measured by various methods including in vivo, in vitro, ex vivo and the like. For example, the test substance is administered to cells such as hepatocytes, mammary gland cells, adipocytes, and skin cells, and the mRNA expression level of TIPARP in the cells is determined by a method such as qPCR, or the protein amount is determined by a method such as western blotting. It can be determined by such factors. However, the measuring method is not limited to the above method, and any other method may be adopted. For example, in vivo or ex vivo methods such as measuring the mRNA expression level or TIPARP protein level of TIPARP in a sample such as liver, breast, fat, skin tissue / model after administration to an animal such as human may be adopted. ..
