本發明提供用於預防、改善或減少皮膚老化跡象之方法,該方法使用類視色素以外可刺激皮膚之胸腺素β-4表現之活性劑。本發明亦提供篩選刺激胸腺素β-4表現程度之物質的方法,及使用該篩選方案所鑑別之活性劑用於皮膚治療之方法。
Description
本發明概言之係關於改良人類皮膚之美學外觀及健康之方法亦及鑑別用於治療皮膚之化合物之方法。具體而言,本發明係關於除類視色素以外可刺激皮膚之胸腺素β-4表現的化合物。
胸腺素係指生物化學及功能上相異之蛋白質家族,其現已知存於許多其他組織中,且其具有多種不同生理機能。不同物種中已鑑別出β-胸腺素之20種以上同型異構體,且在人類中,已鑑別出三種β-胸腺素,包括胸腺素β-4、胸腺素β-10及胸腺素β-15,其均共享大量胺基酸序列同源性。儘管此同源性,該等胸腺素β蛋白中之每一者均係具有不同機能之相異基因產物。
胸腺素β-4係最豐富之β-胸腺素,其係高度保守之水溶性胺基酸酸性多肽。編碼胸腺素β-4之哺乳動物基因局域化至X-染色體。X連接之人類胸腺素β-4具有44個胺基酸(msdkpdmaei ekfdksklkk tetqeknplp sketieqekq ages,SEQ ID NO:1),且藉由去除甲硫胺醯基殘基而處理成分子量為4.9 kDa之43胺基酸肽逸出X滅活(Girardi,M.等人,Immunology,2003,109:1-7)。胸腺素β-4局域化至細胞之細胞質及核。胸腺素β-4存於許多組織中,且具有多種生物機能。其有效地調節肌動蛋白聚合,刺激組織重塑、細胞分化、以及損傷後之細胞及組織癒合,且亦涉及多種發
炎趨化因子及細胞因子之表現。
本發明者已檢驗視黃醇於人類皮膚中之操作模式,且已發現視黃醇係胸腺素β-4之有效上調劑。此令人驚奇之結果導致搜尋其他試劑,其上調胸腺素β-4,可用作視黃醇之潛在替代物或代替物用於治療及改良人類皮膚之美學外觀及健康。
本發明之目的係提供用於治療、改善、抑制及/或預防皮膚老化跡象之組合物及方法。本發明之另一目的係提供藉由誘發胸腺素β-4於皮膚細胞中之表現以改良皮膚外觀來治療、改善、抑制及/或預防皮膚老化跡象的方法。本發明之又一目的係提供除類視色素以外可刺激胸腺素β-4表現之化合物達足以改良該人類皮膚之美學外觀的時間,及提供藉由投與刺激或上調胸腺素β-4於皮膚細胞中之表現之試劑來鑑別可用於治療、改善、抑制及/或預防皮膚老化跡象之化合物的方法。
前述論述僅提出用以更好地理解業內面臨之問題之性質且不應以任何方式理解為承認先前技術。
根據前述目的及其他,本發明提供除類視色素以外胸腺素β-4之刺激劑用以改良一或多個皮膚老化跡象。刺激劑上調胸腺素β-4於皮膚中之含量。據信,真皮纖維母細胞及表皮角質細胞內之胸腺素β-4之上調劑導致細胞內之蛋白質產生增加,該等蛋白質包括(例如)纖維母細胞特異性蛋白、膠原、彈性蛋白及微纖維蛋白及角質細胞蛋白角蛋
白。由於產生纖維母細胞之蛋白質對整個皮膚強度及健康之重要性,故胸腺素β-4之上調將具有減輕皮膚老化外觀之有利效應。
在本發明之一個態樣中,提供改良人類皮膚之美學外觀之方法,其包含對有需要之皮膚區域局部施用有效量之除類視色素以外可刺激胸腺素β-4表現之活性劑達足以改良該人類皮膚之美學外觀的時間。時間之足夠性將由個體反應決定,具體而言若治療皺紋及/或細紋,但涵蓋每日投與一次達一至四週。
在本發明之另一態樣中,提供篩選候選物質以鑑別用於改良皮膚之美學外觀之活性物的方法。該方法包含分析候選物質刺激真皮纖維母細胞或角質細胞中之胸腺素β-4表現的能力。該方法通常涉及將人類真皮纖維母細胞或角質細胞與候選物質一起培育且隨後藉由諸如定量聚合酶鏈反應(qPCR)等定量技術量測編碼胸腺素β-4之mRNA之含量。該分析中所用之細胞可為表現胸腺素β-4之任何動物細胞,但較佳係哺乳動物細胞,且更佳係人類或小鼠細胞。
亦提供改良人類皮膚之美學外觀之方法,其包含對有需要之皮膚區域局部施用有效量之刺激人類皮膚細胞(例如真皮纖維母細胞及表皮角質細胞)中之胸腺素β-4含量的物質。胸腺素β-4刺激劑在本文中稱作「活性物」或上調劑,且通常調配於化妝品上可接受之媒劑中且局部施用至人類外皮(例如面、頸、手、胸、腿等之皮膚)達足以增強其健康或美學外觀之時間。
在本發明之一個態樣中,提供改良人類皮膚之美學外觀之方法,其包含對有需要之皮膚區域局部施用有效量之刺激(例如上調)胸腺素β-4之細胞含量的活性劑,其中藉由量測與活性劑接觸之細胞中之胸腺素β-4之表現程度的分析測定活性劑刺激胸腺素β-4之能力。該分析中所用之細胞可為表現胸腺素β-4之任何動物細胞,但較佳係哺乳動物細胞,且更佳係人類或小鼠細胞。細胞可為皮膚細胞,例如纖維母細胞或角質細胞。該分析可量測胸腺素β-4之任何同源物、片段或標記的含量,但通常所量測者係由人類基因TMSB4X或哺乳動物基因tmsb4x表現之胸腺素β-4的表現程度。人類基因TMSB4X或小鼠基因tmsb4x之表現程度可藉由(例如)以任何適宜技術(例如定量聚合酶鏈反應(qPCR))量測相應mRNA之表現程度來測定。
本文所用術語「胸腺素β-4」係指蛋白質,例如人類中由TMSB4X基因編碼且哺乳動物(例如小鼠)中由tmsb4x基因編碼之蛋白質。如本發明中所述之胸腺素β-4蛋白質(及編碼胸腺素β-4之其相關RNA及/或DNA)可來自任何動物,但通常係人類或小鼠胸腺素β-4,且較佳係人類胸腺素β-4。本文用於闡述特定胸腺素β-4實例之命名法係National Center for Biotechnology Information(「NCBI」),登錄號NP_066932(人類,胸腺素β-4,蛋白質)、NM_021109(人類,胸腺素β-4,mRNA)、NP_067253(小鼠,胸腺素β-4,蛋白質)、NM_021278(小鼠,胸腺素β-4,mRNA),其以引用方式併入並概述於表1中。
亦提供治療皮膚病況之方法,其包含對有需要之皮膚區域局部施用有效量之上調胸腺素β-4的活性劑,其中藉由量測與該活性劑接觸之細胞中之胸腺素β-4之表現程度的分析測定該活性劑刺激胸腺素β-4之能力。
亦提供治療皺紋及/或細紋之方法,其包含對有需要之皮膚區域局部施用有效量之上調胸腺素β-4的活性劑,其中藉由量測與該活性劑接觸之細胞中之胸腺素β-4之表現程度的分析測定該活性劑上調胸腺素β-4之能力。分析步驟最通常包含將人類真皮纖維母細胞與候選物質一起培育且隨後量測編碼胸腺素β-4之mRNA之含量,其中部分基於候選物質上調胸腺素β-4表現之能力選擇候選物質用作活性劑。該分析中所用之細胞可為表現胸腺素β-4之任何動物細胞,但較佳係哺乳動物細胞,且更佳係人類或小鼠細胞。
在本發明之另一態樣中,提供用於改良人類皮膚之美學外觀的化妝品組合物,其包含呈油包水型或水包油型乳液形式之化妝品上可接受之媒劑及有效量之除類視色素以外可上調胸腺素β-4之活性劑。

本文所用術語「胸腺素β-4」係指蛋白質,例如人類中由TMSB4X基因編碼且小鼠中由tmsb4x基因編碼之蛋白質。如本發明中所述之胸腺素β-4蛋白質(及編碼胸腺素β-4之其相關RNA及/或DNA)可來自任何動物,但通常係人類或小鼠胸腺素β-4,且較佳係人類胸腺素β-4。本文用於闡述特定胸腺素β-4實例之命名法係National Center for Biotechnology Information(「NCBI」),登錄號NP_066932(人類,胸腺素β-4,蛋白質)、NM_021109(人類,胸腺素β-4,mRNA)、NP_067253(小鼠,胸腺素β-4,蛋白質)、NM_021278(小鼠,胸腺素β-4,mRNA),其以
引用方式併入並概述於表1中(參見SEQ ID NO:1-4)。
如本發明涵蓋之胸腺素β-4包括如自任何動物獲得之具有胸腺素β-4之生物機能之此蛋白質之任何全長、片段或衍生物、以及編碼胸腺素β-4之相應RNA及/或DNA序列。本文所用胸腺素β-4亦係指多肽屬,其另外涵蓋具有胺基酸序列SEQ ID NO:1及SEQ ID NO:3之蛋白質、以及彼等與該等胺基酸序列具有高相似程度(至少90%同源性)且蛋白質及多肽具有胸腺素β-4之生物機能之蛋白質及多肽。另外,用於本發明中之包含SEQ ID NO:2或SEQ ID NO:4中所述核酸序列之一部分或整個序列之寡核苷酸包括(例如)包含與SEQ ID NO:2或SEQ ID NO:4中所述核酸序列共享約70%或更大、較佳約80%或更大、更佳約90%或更大且進一步較佳約95%或更大同源性的鹼基序列之寡核苷酸,或包含序列表之SEQ ID NO:2或SEQ ID NO:4中所述核酸序列之一部分或整個序列的寡核苷酸。

胸腺素β-4之表現程度與皮膚老化間之相關性之發現已產生一種用於鑑別潛在胸腺素β-4刺激劑之篩選方法。在
一個實施例中,提供一種分析,用於測定細胞經候選物質處理、培育或接觸後胸腺素β-4之表現程度。術語「候選物質」係指除類視色素以外任何經測試作為胸腺素β-4刺激劑之活性之物質,不管是否懷疑該物質具有該活性。細胞可為來自任何動物之任何細胞,其中該細胞表現胸腺素β-4。在一個實施例中,該細胞係哺乳動物纖維母細胞。在另一實施例中,該細胞係哺乳動物角質細胞。較佳地,該細胞係人類或小鼠細胞。在該細胞與候選物質一起培育足以提供可測量表現程度變化之時間長度(其通常為至少1小時,更通常為約12小時至約72小時)後,溶解該細胞以釋放細胞組份,例如胸腺素β-4及編碼胸腺素β-4之mRNA。隨後可藉由任何適於檢測並定量肽及蛋白質及/或多核苷酸(例如mRNA)之技術測量胸腺素β-4蛋白質或mRNA之量。
測量胸腺素β-4之表現程度之較佳方法涉及定量mRNA表現。適於測定mRNA表現之方法包括定量PCR(QPCR)、即時QPCR、逆轉錄PCR(RT-PCR)及定量逆轉錄酶PCR(QRT-PCR),為業內所熟知。如美國專利第7,101,663號及第7,662,561號(其揭示內容以引用方式併入本文中)中詳細闡述,用於檢測mRNA之定量逆轉錄聚合酶鏈反應(QRT-PCR)可包括以下步驟:(a)將來自細胞溶解物之RNA試樣與逆轉錄酶及高濃度靶標序列特異性逆轉錄酶引物在適於產生cDNA之條件下一起培育;(b)隨後向逆轉錄酶反應中添加適宜聚合酶鏈反應(PCR)試劑,包括高濃度對cDNA具
有特異性之PCR引物組及對逆轉錄酶反應熱穩定之DNA聚合酶;及(c)在適於產生對cDNA具有特異性之PCR產物(「擴增子」)的條件下使PCR反應循環期望循環數量。可在固定數量之PCR循環後比較QRT-PCR製程之產物,以測定RNA物質與給定參考基因(例如GAPDH(甘油醛-3-磷酸脫氫酶))相比之相對量。更通常地,藉由分析每一PCR引物組之擴增子產生之相對速率、例如藉由以下來監測PCR反應過程:(1)插入任何雙鏈DNA之非特異性螢光染料,及/或(2)由經螢光報告基因標記之寡核苷酸組成的序列特異性DNA探針,該螢光報告基因僅允許在探針與其互補DNA靶標雜交後檢測。
mRNA可為任何與任何動物之胸腺素β-4相關之mRNA,包括編碼胸腺素β-4之mRNA(例如彼等表1中所鑑別者)或任何多核苷酸或其片段或衍生物。在一個實施例中,mRNA尤其編碼胸腺素β-4。在一較佳實施例中,mRNA編碼人類胸腺素β-4。
可將mRNA表現程度與未經候選物質處理之對照比較以測定相對刺激程度。在一些實施例中,候選物質將mRNA表現上調至少約10%、更適宜地至少約20%、至少約30%、至少約40%或至少約50%。較佳地,候選物質將mRNA表現上調至少約60%、至少約70%、至少約80%、至少約90%或至少約100%。可選擇除類視色素以外可滿足該等標準之候選物質用於其他評價。類視色素(例如視黃醇A及視黃酸)係用於抗皺紋乳霜中之最常見活性劑。然而,
類視色素在皮膚上之用途與多種副作用(例如皮膚刺激、發紅及搔癢、脫皮、皮膚乾燥及對日光敏感)相關。
本發明之胸腺素β-4刺激劑(例如彼等藉由前述篩選方案鑑別者)可用作化妝品製劑中之活性劑且可與其他化妝品上可接受之組份(例如媒劑)一起調配成局部施用至皮膚之組合物。與使用類視色素相比,使用三種胸腺素β-4刺激劑導致較少皮膚刺激、發紅及搔癢、脫皮、皮膚乾燥及對日光敏感。將組合物以有效量局部施用至皮膚,該有效量意指足以達成可量測之皮膚健康改良或一或多個皮膚老化跡象減輕的量。該等皮膚老化跡象包括(但不限於)以下:(a)治療、減少及/或預防細紋或皺紋;(b)減小皮膚毛孔大小;(c)改良皮膚厚度、豐滿度及/或緊實度;(d)改良皮膚平滑度、柔順度及/或柔軟度;(e)改良皮膚色調、光彩度(radiance)及/或透明度;(f)改良原膠原及/或膠原產生;(g)改良彈性蛋白之保持及重塑;(h)改良膚質及/或促進煥膚;(i)改良皮膚障壁修復及/或機能;(j)改良皮膚輪廓之外觀;(k)恢復皮膚光澤及/或亮度;(l)補充皮膚之必需營養素及/或成份;(m)改良因老化及/或更年期而衰減之皮膚外觀;(n)改良皮膚濕潤性;
(o)增強皮膚彈性及/或回彈性;(p)治療、減少及/或預防皮膚下垂;(q)改良皮膚堅實度;及/或(r)減少色素斑及/或斑點之皮膚。
實際上,將本發明之組合物(僅包括刺激胸腺素β-4表現程度之試劑或存於化妝品上可接受之媒劑中)施用至需要治療之皮膚。亦即,對患有任何上述屬性之缺失或喪失或否則將受益於任何上述皮膚屬性之改良的皮膚使用本發明之組合物。通常將皮膚每日治療一次或兩次。治療可繼續1週、2週、4週、8週、6個月或更長時間。較佳地,每日一次投與治療達至少四週之時段。治療長度由反應、具體而言由細紋及/或皺紋之有效治療決定。
