Description

本発明は、クロメ、アナメ、及びホンダワラから選ばれる1種又は2種以上の海藻の抽出物を有効成分として含有するWnt発現抑制剤に関する。より詳細には、本発明は、Wntの発現を抑制することにより、Wnt/β−カテニンシグナルの亢進に関連する疾患の治療または予防に有効なWnt発現抑制剤に関する。   The present invention relates to a Wnt expression inhibitor containing as an active ingredient an extract of one or more seaweeds selected from Kurome, Aname and Hondabara. More specifically, the present invention relates to a Wnt expression suppressor effective for treating or preventing a disease associated with enhancement of Wnt / β-catenin signal by suppressing Wnt expression.

Wntは分泌性糖タンパク質で、線虫やショウジョウバエから哺乳類に至るまで生物種を超えて広く保存されている。Wntは、発生、器官や臓器の形成、細胞の分化・増殖・運動・極性など様々な生命活動に関与する重要なタンパク質であり、哺乳類では19種類が同定されている(非特許文献1)。Wntの命名は、ショウジョウバエの分節遺伝子Wingless(Wg)とマウス乳癌で同定された遺伝子int-Iに由来する。Wntが細胞に作用することにより活性化される細胞内伝達機構は「Wntシグナル経路」と呼ばれ、β−カテニンを介して遺伝子発現を制御する「β−カテニン経路」と、β−カテニンに依存しない「β−カテニン非依存性経路」が存在する。β−カテニン経路(Wnt/β−カテニンシグナル)では、Wntが細胞膜上の受容体(Frizzled)に結合するとGSK-3β(Glycogen synthase kinase-3β)によるリン酸化が抑制され、分解を免れたβ−カテニンが核内へと移行し、遺伝子発現を介して細胞の増殖や分化を促すことが知られている(非特許文献2)。β−カテニン経路に関与するWntとしては、Wnt1、Wnt2、Wnt3、Wnt3a、Wnt7a等が知られている(非特許文献3)。一方、β−カテニンを介さないβ−カテニン非依存性経路は、平面内細胞極性経路(PCP経路)とCa2+経路に分類され、細胞運動や、細胞極性の調節、あるいはβ−カテニン経路の抑制に働く(非特許文献4、5)。β−カテニン非依存性経路に関与するWntとしては、Wnt4、Wnt5a、Wnt11等が知られている(非特許文献3)。 Wnt is a secreted glycoprotein that is widely conserved across species from nematodes and Drosophila to mammals. Wnt is an important protein involved in various biological activities such as development, formation of organs and organs, cell differentiation / proliferation / motility / polarity, and 19 types have been identified in mammals (Non-patent Document 1). The nomenclature of Wnt is derived from the Drosophila segmental gene Wingless (Wg) and the gene int-I identified in mouse breast cancer. The intracellular transduction mechanism activated by Wnt acting on cells is called "Wnt signaling pathway" and depends on "β-catenin pathway" which controls gene expression via β-catenin and β-catenin There is no “β-catenin independent pathway”. In the β-catenin pathway (Wnt / β-catenin signal), when Wnt binds to a receptor (Frizzled) on the cell membrane, phosphorylation by GSK-3β (glycogen synthase kinase-3β) is suppressed and β- It is known that catenin translocates into the nucleus and promotes cell proliferation and differentiation via gene expression (Non-patent Document 2). As Wnt involved in the β-catenin pathway, Wnt1, Wnt2, Wnt3, Wnt3a, Wnt7a and the like are known (Non-patent Document 3). On the other hand, β-catenin independent pathways not mediated by β-catenin are classified into planar cell polarity pathway (PCP pathway) and Ca 2+ pathway, and control of cell movement, cell polarity or suppression of β-catenin pathway Work (Non-Patent Documents 4 and 5). As Wnts involved in the β-catenin independent pathway, Wnt4, Wnt5a, Wnt11 and the like are known (Non-patent Document 3).

このように、Wntは複数の細胞内シグナル伝達機構に関与し、多様な細胞応答を制御するので、Wntシグナル経路は、生体の組織を構成する細胞の機能維持にとって不可欠である一方、その異常は様々な疾患や病態と関連している。実際、Wntシグナル経路の構成分子の遺伝子異常やタンパク質の機能異常が癌、アルツハイマー病、糖尿病、精神系疾患、心疾患、骨・軟骨疾患などに関連するという報告がある。なかでも、細胞の増殖や分化の制御に関与するWnt/β−カテニンシグナルの異常は、癌との関連性が深く、乳癌、大腸癌、胃癌、肺癌、食道癌、神経膠芽腫、及び線維腫などの癌においてWnt/β−カテニンシグナルの亢進が認められる。Wnt非存在下では、細胞質内のβ−カテニンがAPC (adenomatous polyposis coli)、GSK−3βとともにAxinに結合し、このβ−カテニン分解複合体(Axin複合体)中でCKI-1α(casein kinase Iα)と、GSK−3βとによるリン酸化を受けたβ−カテニンが、さらにユビキチン化を受けてプロテアソームによって分解されるので細胞内のβ−カテニン量は低い状態に保たれている。ところが、癌細胞では、共通してβ−カテニンの細胞質や核での異常蓄積が認められる。癌細胞の増殖は、この異常蓄積したβ−カテニンと転写因子であるT cell factor/ lymphoid enhancer factor (Tcf/Lef)とが結合し、cyclin D1やc-Mycなどの癌関連遺伝子が過剰発現することによると考えられている。   Thus, since Wnt is involved in multiple intracellular signaling mechanisms and regulates diverse cellular responses, the Wnt signaling pathway is essential for maintaining the function of cells that constitute a tissue of the living body, while its abnormality is It is associated with various diseases and conditions. In fact, there are reports that genetic abnormalities and protein functional abnormalities of components of the Wnt signaling pathway are associated with cancer, Alzheimer's disease, diabetes, psychiatric diseases, heart diseases, bone and cartilage diseases and the like. Among them, abnormalities in Wnt / β-catenin signaling involved in the control of cell proliferation and differentiation are closely related to cancer, and breast cancer, colon cancer, gastric cancer, lung cancer, esophageal cancer, glioblastoma, and fibers Enhanced Wnt / β-catenin signaling is observed in cancers such as tumors. In the absence of Wnt, cytoplasmic β-catenin binds to Axin together with APC (adenomatous polyposis coli), GSK-3β, and CKI-1α (casein kinase Iα) in this β-catenin degradation complex (Axin complex) Since β-catenin phosphorylated by GSK-3β is further ubiquitinated and degraded by the proteasome, the amount of β-catenin in cells is maintained at a low level. However, in cancer cells, abnormal accumulation in the cytoplasm and nucleus of β-catenin is commonly found. In the growth of cancer cells, this abnormally accumulated β-catenin is combined with the transcription factor T cell factor / lymphoid enhancer factor (Tcf / Lef) to overexpress cancer-related genes such as cyclin D1 and c-Myc. It is believed to be due.

また、皮膚や毛髪のメラニンは、メラノサイトによって合成されるが、Wnt/β−カテニンシグナルは、毛包のバルジ領域付近に存在するメラノサイトの起源となる色素幹細胞からメラノサイトへの分化や、分化したメラノサイトのメラニン合成を制御しており、その亢進は、老人性色素斑、肝斑、雀卵斑、黒子症、シミ、日焼けなどの色素沈着を引き起こす。   In addition, melanin in skin and hair is synthesized by melanocytes, but Wnt / β-catenin signal is the differentiation of melanocytes from melanocytes, which are the origin of melanocytes present in the bulge region of hair follicle, and differentiated melanocytes Regulates melanin synthesis, and its enhancement causes pigmentation such as senile pigmented spots, melasma spots, sputum spots, lentigo, spots and sunburns.

このようなWntシグナル経路の異常を制御して正常な状態に戻すことが、Wntシグナル経路の異常に関連する疾患や病態の治療の選択肢の一つとして期待されており、研究が進んでいる。例えば、Wnt/β−カテニンシグナルを抑制するように制御する例としては、Wnt1、Wnt3、Wnt3a、Wnt7a、Wnt7b、Wnt10bの発現を抑制するポリヌクレオチドを用いる色素沈着の予防または改善剤(特許文献1)、Wnt2の発現を抑制するポリヌクレオチドやその機能を阻害するモノクローナル抗体を用いた癌の治療方法などがある(特許文献2)。また、Wntシグナルは、細胞レベルにおいて、胚性幹細胞や組織特異的幹細胞(筋芽細胞、骨芽細胞、神経幹細胞、小腸幹細胞、色素幹細胞、造血幹細胞、表皮幹細胞、毛包幹細胞、骨髄及び脂肪組織由来間葉系幹細胞など)の増殖および末分化状態の維持に関与することも明らかになっており、これらの幹細胞の増殖や分化の制御のためにWntの発現を抑制するポリヌクレオチドも開発されている(特許文献3)。   It is expected that one of the treatment options for diseases and conditions associated with Wnt signaling disorders is to control such Wnt signaling disorders to return to normal status, and research is in progress. For example, as an example of controlling to suppress Wnt / β-catenin signal, an agent for preventing or improving pigmentation using a polynucleotide that suppresses expression of Wnt1, Wnt3, Wnt3a, Wnt7a, Wnt7b, Wnt10b (Patent Document 1) ), A polynucleotide for suppressing the expression of Wnt2, and a method for treating cancer using a monoclonal antibody that inhibits the function thereof (Patent Document 2). In addition, Wnt signal is, at the cell level, embryonic stem cells and tissue specific stem cells (myoblasts, osteoblasts, neural stem cells, small intestine stem cells, pigmented stem cells, hematopoietic stem cells, epidermal stem cells, hair follicle stem cells, bone marrow and adipose tissue) Have also been shown to be involved in the maintenance of the proliferation and differentiation status of (such as derived mesenchymal stem cells), and polynucleotides have also been developed that suppress the expression of Wnt to control the proliferation and differentiation of these stem cells. (Patent Document 3).

従って、Wntシグナルを適切に制御することは、各種疾患の治療のみならず、幹細胞の増殖や分化を効率的に制御する上でも有用であるが、上記のようなポリヌクレオチドや抗体タンパク質は、生体内に存在する酵素により分解されやすく、また生体内に導入する手段が煩雑であるため日常的な使用が困難である。よって、これらに代わる新たな因子の解明が望まれている。   Therefore, proper control of Wnt signaling is useful not only in the treatment of various diseases but also in efficiently controlling stem cell proliferation and differentiation, but such polynucleotides and antibody proteins as described above are viable. It is easily degraded by enzymes present in the body, and the means for introducing it into the living body is complicated, so daily use is difficult. Therefore, elucidation of new factors to replace these is desired.

Wntとは、Wntシグナル経路に関与するタンパク質をいい、現在までに、ヒトのWntタンパク質は、19種類同定されている(Wnt1、Wnt2、Wnt2b、Wnt3、Wnt3a、Wnt4、Wnt5a、Wnt5b、Wnt6、Wnt7a、Wnt7b、Wnt8a、Wnt8b、Wnt9a、Wnt9b、Wnt10a、Wnt10b、Wnt11、Wnt16)。Wntシグナル経路には、細胞表面のWnt受容体に結合することによってβ−カテニンの安定化を介して遺伝子発現を誘導するβ−カテニン経路、JNKやRhoキナーゼを活性化するPCP経路、PKCなどを活性化するCa2+経路があるが、本発明におけるWntは、β−カテニン経路(以下、「Wnt/β−カテニンシグナル」と記載することもある)に関与するタンパク質をいう。よって、本発明のWnt発現抑制剤が作用するWntは、Wnt/β−カテニンシグナルに関与するWntをいい、例えば、Wnt1、Wnt2、Wnt3、Wnt3a、Wnt7a、Wnt7b、Wnt10a、Wnt10b等が挙げられる。本発明において「Wntの発現抑制」とは、上記WntのmRNA発現及びタンパク質発現を抑制することをいう。 Wnt is a protein involved in the Wnt signaling pathway, and up to now, 19 types of human Wnt proteins have been identified (Wnt1, Wnt2, Wnt2b, Wnt3, Wnt3, Wnt4, Wnt5a, Wnt5b, Wnt6, Wnt7a , Wnt7b, Wnt8a, Wnt8b, Wnt9a, Wnt9b, Wnt10a, Wnt10b, Wnt11, Wnt16). The Wnt signaling pathway includes the β-catenin pathway that induces gene expression through stabilization of β-catenin by binding to Wnt receptors on the cell surface, the PCP pathway that activates JNK and Rho kinase, PKC, etc. Although there is an activating Ca 2+ pathway, Wnt in the present invention refers to a protein involved in β-catenin pathway (hereinafter sometimes referred to as “Wnt / β-catenin signal”).

The evaluation experiment of the Wnt1 expression suppression effect of the extract of each seaweed of chromee, aname and Hondawara was performed as follows.

(試験例1)Wnt1発現抑制効果の評価
20%(v/v)ウシ胎児血清(FBS、ニチレイバイオ社製)を含有するDulbecco's Modified Eagle's Medium(DMEM、Sigma-Aldrich社製)を用いて培養したヒト扁平上皮がん細胞HSC-1(Wnt1発現細胞、JCRB細胞バンク製)を、2%(v/v)FBS含有DMEMに懸濁し、8ウェルカルチャースライドに1x103個ずつ播種した。24時間培養後、クロメ、アナメ、及びホンダワラの各海藻の抽出物 (製造例1〜12)を最終濃度が0.01%(w/v)になるように添加した2%(v/v)FBS含有DMEMに交換し、さらに72時間培養した。細胞をPBS(-)にて2回洗浄し、4%(w/v)パラホルムアルデヒドを加え、室温で10分間インキュベーションして細胞を固定した。
(Test Example 1) Evaluation of Wnt1 expression suppression effect
Human squamous cell carcinoma cell HSC-1 (Wnt1) cultured using Dulbecco's Modified Eagle's Medium (DMEM, Sigma-Aldrich) containing 20% (v / v) fetal bovine serum (FBS, Nichirei Bio) The expression cells (manufactured by JCRB cell bank) were suspended in DMEM containing 2% (v / v) FBS and seeded at 1 × 10 3 in 8-well culture slides. After culture for 24 hours, extracts of each algae of chromite, aname and honda walla (Product Examples 1 to 12) were added to a final concentration of 0.01% (w / v) and contained 2% (v / v) FBS. It was replaced with DMEM and cultured for an additional 72 hours. The cells were washed twice with PBS (−), 4% (w / v) paraformaldehyde was added, and the cells were fixed by incubation for 10 minutes at room temperature.

細胞をPBS(-)にて2回洗浄し、2%(w/v)ウシ血清アルブミン(BSA、和光純薬工業社製)含有PBS(-)に抗Wnt1抗体(Spring Bioscience社製)及び抗β-アクチン抗体を添加した一次抗体溶液を加え、37℃で1時間インキュベーションした。細胞をPBS(-)にて2回洗浄し、2%(w/v)BSA含有PBS(-)にAlexa488標識抗ウサギIgG抗体及びAlexa594標識抗マウスIgG抗体を添加した二次抗体溶液を加え、37℃で1時間インキュベーションした。細胞をPBS(-)にて2回洗浄し、蛍光顕微鏡(Olympus社製)を用いて観察し、Wnt1の発現を緑色の蛍光として、β-アクチンの発現を赤色の蛍光として画像を撮影した。取得した画像について、市販の解析ソフトを用いて測定した蛍光強度を指標に各タンパク質の発現量を測定し、Wnt1の相対発現量(緑色の蛍光強度/赤色の蛍光強度)を算出した。試料を添加せずに培養した細胞におけるWnt1の相対発現量を100%とし、これに対し、試料を添加して培養した細胞におけるWnt1の相対発現量の値を算出し、評価した。結果を表1に示す。   The cells were washed twice with PBS (-), and 2% (w / v) bovine serum albumin (BSA, manufactured by Wako Pure Chemical Industries, Ltd.) in PBS (-) containing anti-Wnt 1 antibody (manufactured by Spring Bioscience) and anti-Wnt 1 The primary antibody solution to which the β-actin antibody was added was added and incubated at 37 ° C. for 1 hour. The cells are washed twice with PBS (-), and a secondary antibody solution in which Alexa 488 labeled anti-rabbit IgG antibody and Alexa 594 labeled anti-mouse IgG antibody are added to PBS (-) containing 2% (w / v) BSA is added, Incubated at 37 ° C. for 1 hour. The cells were washed twice with PBS (−), observed using a fluorescence microscope (Olympus), and images were taken with Wnt1 expression as green fluorescence and β-actin expression as red fluorescence. About the acquired image, the expression level of each protein was measured using the fluorescence intensity measured using commercially available analysis software as an index, and the relative expression level of Wnt 1 (green fluorescence intensity / red fluorescence intensity) was calculated. The relative expression level of Wnt1 in cells cultured without addition of sample was defined as 100%, whereas the value of the relative expression level of Wnt1 in cells cultured with addition of sample was calculated and evaluated. The results are shown in Table 1.
