    • 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-alpha, IFN-gamma, IL-10, IL-12p70, IL-13, IL-16, IL-18, IL1beta, 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-1alpha, MIP-1beta, MPIF-1, NAP-2, RANTES, sCD23, OSM, TARC, TNF-alpha, 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。
