CCLM:miR-4449可作为多发性骨髓瘤中潜在的血液标志物

2017-05-18 MedSci MedSci原创

miRNA在不同的生物过程中起作用,包括发育,细胞生长,细胞凋亡和造血作用。此外,研究表明它们在癌症中也发挥很多重要的调节作用。 来自中国南通大学的研究人员使用微阵列分析和实时定量PCR(RT-qPCR)检查了CD138 +原代多发性骨髓瘤(MM)细胞中的miRNA表达。通过RT-qPCR检测71例初级MM患者和46例健康对照的血清miR-4449表达水平。

近日,国际杂志Clinical Chemistry and Laboratory Medicine上在线发表一项关于miR-4449可以作为多发性骨髓瘤中潜在的血液标志物的研究。

miRNA在不同的生物过程中起作用,包括发育,细胞生长,细胞凋亡和造血作用。此外,研究表明它们在癌症中也发挥很多重要的调节作用。

来自中国南通大学的研究人员使用微阵列分析和实时定量PCRRT-qPCR)检查了CD138 +原代多发性骨髓瘤(MM)细胞中的miRNA表达。通过RT-qPCR检测71例初级MM患者和46例健康对照的血清miR-4449表达水平。

研究分析显示与健康对照相比,MM受试者中的54miRNA发生上调,28miRNA下调。miR-4449MM中尚未报道。发现MM患者骨髓miR-4449的相对表达(2.14±1.42)高于健康对照组(0.815±0.165)(U = 8p = 0.0093)。在MM患者血清的miR-4449的相对表达(2.11±2.10)显著高于健康对照组(0.357±0.235)(U = 374P <0.0001,并且与 β2M,λ和κ轻链浓度(r = 0.480p = 0.0003; r = 0.560p <0.0001; r = 0.560p <0.0001)显著相关,但与乳酸脱氢酶(LDH)浓度无关(r = 0.247p = 0.0611 。血清miR-4449的受试者ROC曲线下面积(AUC)为0.88595CI0.826-0.945),高于其他标记物。联合miR-4449,λ轻链, β2M,灵敏度最高。

研究认为MM患者血清miR-4449的表达水平显著高于健康对照组,表明其可能有助于MM的辅助诊断

Cancer Cell:北京大学李程研究组等合作发表利用靶向细胞周期的miRNA抑制癌症研究论文

日前,国际著名学术杂志《Cell》子刊、癌症研究领域顶级学术期刊《Cancer Cell》在线发表了美国哈佛大学医学院、Dana-Farber癌症研究所Piotr Sicinski教授研究组与北京大学生命科学学院、统计科学中心李程研究组合作题为 “Cell-Cycle-Targeting MicroRNAs as Therapeutic Tools against Refractory Cance

CCLM:miRNA在检验医学中的应用—微小RNA在心血管疾病中的临床应用

微小RNA(miRNA)是短的非编码RNA,它能够结合信使RNA(mRNA),并启动mRNA降解或翻译抑制,并在转录后水平上调控基因表达。在心血管疾病(CVD)中,许多研究已经将miRNA作为具有高诊断和预后能力的强循环生物标志物。在冠状动脉疾病(CAD)和心力衰竭(HF)中,miRNA被认为是可靠的生物标志物,并与建立的蛋白质如心脏肌钙蛋白(cT)或利尿钠肽相匹配。此外,在其他CVD中,miRN

微小RNA(miRNA)可以作为各种疾病进程和确定细胞分化的生物标志物,并且在此方面表现极具前景。这些短序列RNA分子丰度高,能够承受严酷的处理条件和储存条件,并且可以从血液和组织中提取。

CCLM:miRNA在检验医学中的应用—细胞外囊泡微小RNA在癌症生物学中的作用

microRNA(miRNA)是正常和异常生物过程中信使RNA(mRNA)表达的关键调节因子。已经在多种类型的癌症中观察到miRNA的异常表达,并且与恶性癌症表型相关,包括转移和耐药性。miRNA也通过小囊泡分泌。除了细胞miRNA(ce-miRNA)之外,分泌miRNA(se-miRNA)在癌症发展和转移中起重要作用。因此,体液中的se-miRNA已经被研究为癌症治疗的有希望的生物标志物和治疗靶

CCLM:miRNA在检验医学中的应用—血小板相关微小RNA的临床意义

循环血小板在维持止血中起核心作用,参与越来越多的从动脉粥样硬化到癌症转移的病理生理过程。血小板衍生自骨髓巨核细胞,循环寿命为8-10天。它与许多粘附分子(包括与血小板表面受体相互作用的胶原)接触,导致血小板停滞和激活。一旦激活,血小板释放其颗粒物的含量以及二磷酸腺苷(ADP),血清素和血栓素A 2,导致进一步的血小板募集,聚集和栓塞形成。

CCLM:miR-16在结肠直肠腺癌诊断和预后中的应用

结肠直肠腺癌是胃肠道最常见的恶性肿瘤之一,也是西方国家第二大癌症相关死亡原因之一。miR-16广泛参与癌症进展。在本研究中,来自雅典国家和卡波治理大学生物化学与分子生物学系的研究人员对miR-16在结肠直肠腺癌中的潜在诊断和预后效用进行了研究。
