Abstract
本发明涉及一种增生性瘢痕的预防及治疗用药学组合物。发明人明示了硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子‑5A、膜联蛋白A2及脂肪酸结合蛋白‑5的表达抑制,可成为增生性瘢痕的改善及治疗的新的目标。在本发明中制造硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子‑5A、膜联蛋白A2及脂肪酸结合蛋白‑5‑特异性siRNA,确认了增生性瘢痕的治疗可能性。因此,所述蛋白质或者编码此的基因的抑制在增生性瘢痕诱导细胞消灭并减少胶原蛋白的表达,从而可非常有用的使用在疤痕治疗。
Description
技术领域
本发明涉及瘢痕疙瘩或者增生性瘢痕预防或者治疗用组合物。
背景技术
由于手术或创伤导致真皮深层受损时,保持皮肤张力的真皮层中的胶原蛋白会过度增生,从而在伤口愈合后透出变薄的皮肤,留下皮肤恢复的痕迹,将此称为“普通疤痕”。这是在伤口的愈合结果,或者是在适当调节和抑制伤口愈合过程的功能具有障碍时,纤维组织非正常的密集生长,从而可生成增生性瘢痕(Hypertrophic scars)或者瘢痕疙瘩(Keloid)。增生性瘢痕不会超出伤口范围,并且随着时间的流逝会逐渐消失,但是瘢痕疙瘩具有随着时间的推移会比受损区域生长得更宽,侵入至正常皮肤的差异。为了增生性瘢痕或者瘢痕疙瘩的治疗,尝试过包括手术治疗、放射治疗、类固醇治疗、由硅胶的阻塞敷料、激光治疗,但是只具有限定性效果,且尚没有确立的方法。
增生性瘢痕或者瘢痕疙瘩的生成的原因被公知为在伤口愈合阶段的细胞移动过度活性化,或者组织细胞和毛细血管被异常增殖从而过度形成,或者不能正常分解引起的胶原蛋白过度积聚。注册专利第10-1505294号公开了一种可用于水解胶原蛋白减少疤痕形成的海星孵育提取物,注册专利第10-1697396号公开了一种针对使用将与纤维化相关的结缔组织生长因子(CTGF)作为目标的化合物治疗增生性瘢痕的方法。
对于在治愈疤痕的过程中所积累的必要以上的胶原蛋白的形成及参与细胞增殖的生物标记物的信息几乎没有。通过选择这样的生物标志物,可以准确地诊断出如增生性瘢痕的非正常疤痕,并筛选将所述生物标志物作为目标的物质,从而抑制并治疗增生性瘢痕或者瘢痕疙瘩的形成。
发明内容
发明所要解决的问题
本发明的目的是提供一种瘢痕疙瘩(keloid)或者增生性瘢痕(Hypertrophicscars)的预防或者治疗用药学组合物。
本发明的其他目的是提供一种瘢痕疙瘩(keloid)或者增生性瘢痕(Hypertrophicscars)的预防或者治疗方法。
本发明的其他目的是提供一种瘢痕疙瘩(keloid)或者增生性瘢痕(Hypertrophicscars)的预防或者治疗物质的筛查方法。
本发明的另一个目的是提供一种诊断瘢痕疙瘩(keloid)或者增生性瘢痕(Hypertrophic scars)的方法。
用于解决问题的方案
为了上述目的,发明人比较在增生性瘢痕组织及正常组织显示的多个蛋白质表达差异,从而假设显示非正常表达状态的蛋白质标志物为增生性瘢痕的原因,并且选择与正常组织显示不同表达状态的蛋白质。
由此,本发明提供一种瘢痕疙瘩或者增生性瘢痕诊断用组合物,所述诊断用组合物包括测量由硫氧还蛋白5(TXNDC5)、PRRC1、钙囊素(S100A11)、半乳糖凝集素1(Galectin1)、丝氨酰胺A(Filamin A)、真核起始因子-5A(eIF-5A)、膜联蛋白A2(Annexin A2)及脂肪酸结合蛋白-5(FABP5)形成的群中选择的一个以上的基因,或者由硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子-5A、膜联蛋白A2及脂肪酸结合蛋白-5形成的群中选择的一个以上的蛋白质的表达量的物质。
并且,本发明提供一种瘢痕疙瘩或者增生性瘢痕诊断方法,所述诊断方法包括如下步骤:在瘢痕疙瘩或者增生性瘢痕的组织中,测量由硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子-5A、膜联蛋白A2及脂肪酸结合蛋白-5形成的群中选择的一个以上的基因,或者由硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子-5A、膜联蛋白A2及脂肪酸结合蛋白-5形成的群中选择的一个以上的蛋白质的表达量;以及将所述测量结果与从正常组织的所述基因及蛋白质的表达量进行比较。
所述基因或者蛋白质表达量的测量可通过本领域公知的多种方法实施。例如,可利用RT-PCR(Sambrook等,Molecular Cloning.A Laboratory Manual,3rd ed.ColdSpring Harbor Press(2001))、RNA印迹法(Peter B.Kaufma et al.,Molecular andCellular Methods in Biology and Medicine,102-108,CRC press)、利用cDNA微阵列的杂交反应(Sambrook等,Molecular Cloning.A Laboratory Manual,3rd ed.Cold SpringHarbor Press(2001))、免疫印迹或者在体(in situ)杂交反应(Sambrook等,MolecularCloning.A Laboratory Manual,3rd ed.Cold Spring Harbor Press(2001))实施。
还有,发明者在瘢痕疙瘩或者增生性瘢痕及正常组织,将所述选择的蛋白质表达确认为免疫印迹和免疫组织化学染色。在瘢痕疙瘩或者增生性瘢痕组织中降低(knock-down)编码所述蛋白质的各个基因时,确认了类型I胶原蛋白、α-SMA及PCNA蛋白质表达减少。这些结果支撑所述蛋白质的抑制或者编码此的基因的降低对瘢痕疙瘩或者增生性瘢痕治疗非常有用。
由此,本发明提供一种瘢痕疙瘩(keloid)或者增生性瘢痕(Hypertrophic scars)的预防或者治疗用药学组合物,所述医学组合物包括将抑制由硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子-5A、膜联蛋白A2及脂肪酸结合蛋白-5形成的群中选择的一个以上的基因的表达,或者抑制由硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子-5A、膜联蛋白A2及脂肪酸结合蛋白-5形成的群中选择的一个以上的蛋白质活性的物质作为有效成分。

本发明中,抑制由硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子-5A、膜联蛋白A2及脂肪酸结合蛋白-5形成的群中选择的一个以上的基因表达的物质可包括shRNA(short hairpin RNA,短发夹RNA)、siRNA(small interference RNA,小干扰RNA)、miRNA(microRNA,微小RNA)、Crispr-cas9、Crispr-cpf1、核酶(ribozyme)、脱氧核梅(DNAzyme)、PNA(peptide nucleic acids,肽核酸)、反义寡核苷酸,抑制由所述基因表达的蛋白质活性的物质可包括抗体、适体、天然提取物或者化学物质,只要是抑制所述基因的表达及蛋白质活性的物质,可以不受限制地包括在内。
本说明书中使用的术语“shRNA(short hairpin RNA)”作为具有45至70核苷酸长度的单条线的RNA,在目标基因siRNA碱基序列的意义(sense)与互补的无义之间合成连接3-10个碱基连接肽(linker)的寡核苷酸DNA之后克隆到质粒载体,或者将shRNA插入到逆转录病毒的慢病毒(lentivirus)及腺病毒(adenovirus)并进行表达,则制成具有循环的发夹结构的shRNA,并由细胞内的Dicer转换成siRNA显示RNAi效果。
本发明中的术语“siRNA”意味着妨碍RNA或者可介导基因沉默的核酸分子(参照WO00/44895、WO01/36646、WO99/32619、WO01/29058、WO99/07409及WO00/44914)。siRNA可以抑制目标基因的表达,因此被提供为有效的基因降低方法或者基因治疗方法。siRNA在植物、蠕虫、果蝇及寄生虫首次被发现,并且最近开发/利用siRNA应用于哺乳类细胞研究(Degot S,et al.2002;Degot S,et al.2004;Ballut L,et al.2005)。

在本发明使用的术语“miRNA(microRNA)”作为21-25核苷酸的单条线RNA分子,是通过目标mRNA的破坏或者解毒步骤中的抑制控制真核生物的基因表达的调节物质。这些miRNA由两个步骤的过程形成。miRNA初级转录物(primary miRNA)在核内通过Drosha的RNase III类型酶,被制作成70-90碱基程度的茎环结构,即premiRNA,之后移动至细胞质通过Dicer酶被切断制作21-25碱基的成熟的miRNA。如此形成的miRNA互补地结合在mRNA作用为转录后基因抑制器(post-transcriptional gene suppressor),并且诱导翻译抑制和mRNA不稳定性。miRNA涉及多种生理学现象及疾病。
在本说明书使用的术语“反义寡核苷酸”意味着在特定mRNA的序列含有的互补核算序列的DNA或者RNA,或者这些衍生物,结合在mRNA内的互补序列,其作用为妨碍mRNA作为蛋白质的翻译。本发明的反义序列意味着在所述各基因互补,且可结合在所述各基因mRNA的DNA或者RNA序列,可妨碍对所述基因mRNA的翻译、细胞质内的转位(translocation)、成熟(maturation)或者其他所有整体生物学功能的必要活性。反义核酸的长度可以是6至100碱基,优选为8至60碱基,更有选为10至40碱基。

实施例
人的皮肤成纤维细胞、正常组织及增生性瘢痕组织的准备
用于实验的皮肤组织是从3名患者获得的,且利用男女的正常和scar组织进行了IHC,并且利用从各组织由来的主要成纤维细胞(primary fibroblast cell)观察了由siRNA转化的效果。
用70%乙醇(ethanol)洗涤组织后,通过修建(trimming)去除脂肪并切块(chopping)分离了IHC用组织。在对剩余组织进行进一步修剪后,进行切碎并放入混合有胶原酶(collagenase)、胰蛋白酶(trypsin)和EDTA的溶液,并在37℃和100rpm下分离了细胞。被分离的细胞在补充有10%胎牛血清(FBS)和庆大霉素(gentamycin)的F12培养基中培养。
通过对增生性瘢痕组织的免疫组织化学(IHC)实验的后补蛋白质的表达比较
将从活体解剖(Biopsy)获得的组织放入O.C.T compound(Cell Poth,KMA-0100-00A)并放进干冰进行了冻结。将冻结的组织由丙酮(Acetone)和甲醇(methanol)以1:1的缓冲液进行了固定。解除缓冲液后,在常温将0.5%Triton X-100处理10分钟并进行通透性之后,利用超视双氧水(Ultravision hydrogen peroxide)(Thermo kit/Ultravision LPdetection system)阻碍了肽酶的活性。在常温超视块(Ultravision block)缓冲液反应10分钟之后,处理相应的一次抗体并且处理了4℃一夜(overnight)。一次抗体分别使用了硫氧还蛋白5(Abcam,Ab155684)、PRRC1(Abcam/ab12544)、钙囊素(Abcam/ab97329)、半乳糖凝集素1(Abcam,Ab108389)、丝氨酰胺A(Millipore/MAB1680)、eIF5-A(Abcam/ab32014)、膜联蛋白A2(Cell singnaling/8235)、脂肪酸结合蛋白-5(Abcam/ab37267)。在常温将一级抗增强剂(Primary antibldy enhancer)处理10分钟之后,将酶标二抗(HRP polymer)在阻断光的状态下在常温反应了15分钟。去除HRP polymer之后,将除去PRRC1的所有组织由AEC(Spring,ASS-125),PRRC1由DAB(Thermo,TA-125-HDX)处理了1分钟。在常温由Mayer'shematoxylin染色组织并脱水之后,由加拿大香脂混合二甲苯(Canada balsam mixedXylene)进行安置(mounting)之后,由显微镜进行了观察。
IHC结果,硫氧还蛋白5、PRRC1、钙囊素、半乳糖凝集素1、丝氨酰胺A、真核起始因子-5A、膜联蛋白A2及脂肪酸结合蛋白-5相比正常组织,在增生性瘢痕组织显示表达增加的状态。对于表达增加的状态根据真皮(dermis)及表皮(epidermis)、层的位置显示差异,对于后补蛋白质的表达差异结果在下表1及图1进行了显示。

后补蛋白质特异性siRNA的形制转换效果变化-在增生性瘢痕组织的成纤维细胞的胶原蛋白类型I及a-SMA及PCNA的表达变化
在所述ICH结果选择的所述蛋白质中,对于三种(硫氧还蛋白5、PRRC1、钙囊素)利用了siRNA降低(knock-down)各个基因表达之后,分析了在疤痕过度表达的胶原蛋白及成纤维细胞增殖相关蛋白质等的表达。
具体地,使用了降低硫氧还蛋白-5的siRNA可由sense5'-GGCCCUAACUAGAGUUCUAtt-3'(SEQ ID NO.1)及反义5'-UAGAACUCUAGUUAGGGCCtt-3'(SEQ IDNO.2);降低PRRC1的两种siRNA由sense 5'-CAAGAAGACCCUAGAAUUAtt-3'(SEQ ID NO.3)及反义5'-UAAUUCUAGGGUCUUCUUGtt-3'(SEQ ID NO.4)及sense5'-UAUCAAAUCUGGUGAAtt-3'(SEQ ID NO.5)及反义siRNA UUCACCUCCAGAUUUGAUAtt-3'(SEQ ID NO.6);并且降低钙囊素的siRNA由sense GAACUAGCUGCCACAAtt-3'(SEQ ID NO.7)、反义5'-UUGUGAAGGCAGCUAGUUCtt-3'(SEQ ID NO.8)。
具体地,将从增生性瘢痕组织分离的成纤维细胞在添加10%FBS的F12培养基进行培养之后,将降低各个蛋白质的所述siRNA进行了转染(transfection)。siRNA转染48小时之后,提取溶解产物(lysate)并实施免疫印迹(western blot)观察胶原蛋白等的表达变化。其结果,确认了由siRNA转染的目标蛋白质被降低(图2),通过胶原蛋白-1、α-SMA及PCNA蛋白质表达变化确认了目标蛋白质的降低对成纤维细胞的功能及生长的影响。观察结果,所述三种的所有基因的各个表达被阻碍时,确认了胶原蛋白-1、α-SMA及PCNA蛋白质表达被抑制(图3)。
结论上,由抑制所述各个的蛋白质来有效地抑制在增生性瘢痕过度生成的胶原蛋白的合成阻碍和成纤维细胞的增殖并诱导细胞消灭,因此,确认了所述后补蛋白质可成为改善或者治疗增生性瘢痕的目标。
以上详细地记述了本发明的特定部分,本领域的技术人员应该理解这些具体技术只是优选的实施例,并不能由此限定本发明的范围。因此,本发明的实质性的范围可由权利要求和与此等价物被定义。
