    • Human extracellular ribonucleases (RNases) are widely distributed in various organs and body fluids and together with other members of the mammalian RNase A superfamily. In addition to their RNase activity, several RNases have been shown to have special biological actions, i.e. , antitumor, antiviral and antigiogenic properties. However, the molecular mechanisms of such activities are unclear. Using protein microarrays amplified rolling circle amplification (RCA), we investigated the effects of EDN (Rnase 2), ECP (Rnase 3) and RNase 1om leukocytes cytokine production. We measured the levels of 78 different cytokines and growth factors in culture supernatants to determine the cytokine profiles of cells treated with different combinations of RNases and RNase inhibitors. Members of human ribonuclease family (such as Rnase 1, hEDN (Rnase 2) and Rnase 3 ) induced expression of certain sets of cytokines in human leukocytes, including ENA-78, EOT2, BLC, GDNF, I309, IFN-α, IFN-γ, IL-10, IL-12p70, IL-13, IL-16, IL-18, IL1β, IL-1ra, IL-2Sra, IL-3, IL-6, IL-6Sr, IL-7, IL-8, IP-10, MCP-1, MCP-2, MCP-3, MCSF, MIG, MDC, MIP-1α, MIP-1β, MPIF-1, NAP-2, RANTES, sCD23, OSM, TARC, TNF-α, TNF-R1 and uPAR. Thus members of the Rnase superfamily are therapeutic targets for treatment of inflammatory diseases and clinical conditions. Inhibition or augmentation of Rnase expression is used to modulate the immune system and is beneficial for host defense against various diseases and is exploited as an adjuvant. The expression of Rnases is a diagnostic marker for inflammation related conditions and is used to determine various disease stages. In addition, expression of cytokines, chemokines, growth factors is used to monitor efficacy of Rnase-base therapies.
    • 人类细胞外核糖核酸酶(RNases)广泛分布在各种器官和体液中,并与哺乳动物核糖核酸酶A超家族的其他成员一起分布。 除了它们的RNA酶活性外,已经显示出几种RNA酶具有特殊的生物学作用,即抗肿瘤,抗病毒和抗病毒性质。 然而,这些活动的分子机制尚不清楚。 使用蛋白质微阵列扩增滚环扩增(RCA),我们研究了EDN(Rnase 2),ECP(Rnase 3)和RNase 1om白细胞细胞因子产生的影响。 我们测量培养上清液中78种不同细胞因子和生长因子的水平,以确定用不同RNA酶和RNA酶抑制剂组合处理的细胞的细胞因子谱。 人类核糖核酸酶家族(如Rnase 1,hEDN(Rnase 2)和Rnase 3)的成员诱导人白细胞中某些细胞因子的表达,包括ENA-78,EOT2,BLC,GDNF,I309,IFN-α,IFN- γ,IL-10,IL-12p70,IL-13,IL-16,IL-18,IL1β,IL-1ra,IL-2Sra,IL-3,IL-6,IL-6Sr, 8,IP-10,MCP-1,MCP-2,MCP-3,MCSF,MIG,MDC,MIP-1alpha,MIP-1beta,MPIF-1,NAP-2,RANTES,sCD23,OSM,TARC, α,TNF-R1和uPAR。 因此,Rnase超家族成员是治疗炎症性疾病和临床病症的治疗靶点。 Rnase表达的抑制或增加用于调节免疫系统,有利于宿主防御各种疾病,并被开发为佐剂。 Rnases的表达是炎症相关病症的诊断标记,用于确定各种疾病阶段。 此外,细胞因子,趋化因子,生长因子的表达用于监测Rnase基疗法的疗效。

    • A prerequisite of proteomics is the ability to quantify many selected proteins simultaneously. Fluorescent sandwich immunoassays on microarrays hold appeal for such studies, since equipment and antibodies are readily available, and assays are simple, scalable and reproducible. To attain adequate sensitivity and specificity, however, a general method of immunoassay amplification is required. Coupling of isothermal rolling circle amplification (RCA) to universal antibodies can be used for this purpose: RCA on a synthetic DNA circle is initiated by a complementary oligonucleotide attached to an anti-biotin antibody; single-stranded RCA product remains -attached to the antibody, and is detected by hybridization of complementary, fluorescent oligonucleotides. 51 cytokines were measured simultaneously on microarrays with signal amplification by RCA with high specificity, femtomolar sensitivity and 4 log quantitative range. This cytokine microarray was used to measure secretion from human Dendritic cells (DCs) induced by lipopolysaccharide (LPS) or tumor necrosis factor-alpha (TNF-α). Rapid secretion of inflammatory cytokines such as MIP-1β, IL-8, and IP-10 was induced by LPS. Eotaxin-2 and I-309 were found to be induced by LPS, and MDC, TARC, sIL-6R, and sTNF-RI were found to be induced by TNF-α. Since microarrays can accommodate∼1000 sandwich immunoassays of this type, a relatively small number of RCA microarrays appears to offer a tractable approach for proteomic surveys.
    • 蛋白质组学的先决条件是能够同时量化许多选定的蛋白质。 微阵列上的荧光三明治免疫测定法对这些研究具有吸引力,因为设备和抗体容易获得,并且测定法简单,可扩展和可重复。 然而,为了获得足够的灵敏度和特异性,需要一般的免疫测定法。 可以使用等温滚环扩增(RCA)与通用抗体的偶联用于此目的:合成DNA环上的RCA由连接于抗生物素抗体的互补寡核苷酸引发; 单链RCA产物保留在抗体上,并通过互补荧光寡核苷酸的杂交来检测。 通过RCA具有高特异性,飞生敏感性和4对数定量范围的信号放大的微阵列同时测量51种细胞因子。 该细胞因子微阵列用于测量由脂多糖(LPS)或肿瘤坏死因子-α(TNF-α)诱导的人树突状细胞(DCs)的分泌。 LPS引起炎症细胞因子如MIP-1β,IL-8和IP-10的快速分泌。 发现嗜酸性粒细胞趋化因子-2和I-309被LPS诱导,MDC,TARC,sIL-6R和sTNF-RI均被TNF-α诱导。 由于微阵列可以容纳这种类型的SIMILAR 1000三明治免疫测定,所以相对较少数量的RCA微阵列似乎为蛋白质组学调查提供了一种可行的方法。
