已知毛囊的真皮乳头细胞 (DPC) 可为毛囊细胞分泌旁分泌因子。采用鸟枪法蛋白质组学分析来比较人 DPC 和真皮成纤维细胞 (DF) 的分泌组的表达谱。在本研究中,通过 1DE/LTQ FTICR MS/MS 分析 DPC 和匹配 DF 分泌的蛋白质,使用 emPAI 摩尔百分比值进行半定量测定,然后使用蛋白质相互作用网络分析进行表征。在 DF 和 DPC 中分别鉴定的 1,271 和 1,188 个蛋白质中,使用 Ingenuity Pathway Analysis 工具进一步分析了 1,529 个蛋白质。我们鉴定了 28 种 DPC 特异性细胞外基质蛋白,包括转运蛋白(ECM1、A2M)、酶(LOX、PON2)和肽酶(C3、C1R)。经过生化验证的 DPC 特异性蛋白包括血小板反应蛋白 1 (THBS1)、胰岛素样生长因子结合蛋白 3 (IGFBP3),以及特别令人感兴趣的作为关键网络核心蛋白的整合素 β1 亚基 (ITGB1)。使用鸟枪蛋白质组学技术和网络分析,我们选择 ITGB1、IGFBP3 和 THBS1 作为可能的毛发生长调节蛋白生物标志物。 [BMB 2012 年报告; 45(4):253-258]
The dermal papilla cells (DPCs) of hair follicles are known to secrete paracrine factors for follicular cells. Shotgun proteomic analysis was performed to compare the expression profiles of the secretomes of human DPCs and dermal fibroblasts (DFs). In this study, the proteins secreted by DPCs and matched DFs were analyzed by 1DE/LTQ FTICR MS/MS, semi-quantitatively determined using emPAI mole percent values and then characterized using protein interaction network analysis. Among the 1,271 and 1,188 proteins identified in DFs and DPCs, respectively, 1,529 were further analyzed using the Ingenuity Pathway Analysis tool. We identified 28 DPC-specific extracellular matrix proteins including transporters (ECM1, A2M), enzymes (LOX, PON2), and peptidases (C3, C1R). The biochemically-validated DPC-specific proteins included thrombospondin 1 (THBS1), an insulin-like growth factor binding protein3 (IGFBP3), and, of particular interest, an integrin beta1 subunit (ITGB1) as a key network core protein. Using the shotgun proteomic technique and network analysis, we selected ITGB1, IGFBP3, and THBS1 as being possible hair-growth modulating protein biomarkers. [BMB reports 2012; 45(4): 253-258]
