血清miR-143和miR-145在肝癌中的表达及对预后的影响研究

时间:2019-07-29


ABSTRACT:Lung cancer is known to cause high mortality and morbidity. The study aimed to explore the association between rs3733845 and rs3733846 polymorphisms in the promoter region of miR-143/145 and the risk of lung cancer among 575 nonsmoking cases and 575 cancer-free controls in a Chinese female population. We genotyped two single nucleotide polymorphisms (SNPs) in the promoter region of miR-143/145 in 575 cases and 575 controls using TaqMan allelic discrimination method. Logistic regression analysis was conducted to assess the association between polymorphisms in the promoter of miR-143/miR-145 and risk of lung cancer females. Crossover analysis was used to explore the interaction between the two SNPs and environmental risk factors (cooking oil fume exposure and passive smoking exposure). The results showed that both rs3733845 and rs3733846 polymorphisms were associated with an increased lung adenocarcinoma risk in dominant model (adjusted odds ratio [OR] = 1.329, 95% confidence intervals [CIs] = 1.026-1.723, p = 0.031 and adjusted OR = 1.450, 95% CI = 1.112-1.890, p = 0.006, respectively). The results of crossover analysis revealed that rs3733845 and rs3733846 risk genotypes along with cooking oil exposure increased lung cancer risk by 1.862-fold and 2.260-fold, respectively (adjusted OR = 1.862, 95% CI = 1.105-3.138, p = 0.020 for rs3733845; adjusted OR = 2.260, 95% CI = 1.354-3.769, p = 0.002 for rs3733846). There was positive multiplicative interaction between the two SNPs and cooking oil fume exposure (adjusted OR = 1.362, 95% CI = 1.078-1.719, p = 0.009 for oil × rs3733845; adjusted OR = 1.399, 95% CI = 1.122-1.745, p = 0.003 for oil × rs3733846). In nonsmoking females, rs3733845 and rs3733846 polymorphisms might be associated with lung adenocarcinoma risk. Moreover, the interactions between the two SNPs and cooking oil fume exposure were statistically significant on a multiplicative scale rather than an addictive scale.


肝癌是我国常见的恶性肿瘤之一,具有高发病率、高死亡率的特点。饮食因素在西方国家被认为可引起高达30%的癌症,在癌症潜在可预防的原因中仅次于烟草而占据第二位,在发展中国家饮食对癌症危险的影响大约为20%。人们也越来越关注饮食和肝癌风险间的关系,现就近年来有关肝癌风险与日常饮食关系的研究进行综述,结果如下:1肉类食物红肉及加工肉富含胆固醇和饱和脂肪酸、血红素铁、杂环胺和亚硝酸等,这些物质均与癌症的发生有着密切的关系。


目的为探讨血清miR-143和miR-145在肝癌中的表达及其对预后的影响。方法选取某院2014年6月—2016年1月收治的85例肝癌患者作为肝癌组,良性肝病患者50例作为良性肝病组及体检健康者80例作为健康组。应用荧光定量多聚酶链式反应测定3组血清miR-143、miR-145表达水平;分析肝癌组临床特征与血清miR-143、miR-145表达水平的相关性;应用Kaplan-Meire生存曲线分析miR-143、miR-145高低表达肝癌患者的复发转移率和生存率差异。结果 肝癌组和良性肝病组miR-143、miR-145表达水平均高于健康组,且肝癌组miR-143、miR-145表达水平亦高于良性肝病组,差异均有统计学意义(P<0.01)。肝癌患者血清miR-143、miR-145表达水平与性别、年龄及乙型肝炎病毒感染无关,与肿瘤直径、肿瘤分化等级、甲胎蛋白水平、TNM分级及有无癌栓有关。Kaplan-Meire生存曲线分析显示:miR-143、miR-145高表达肝癌患者复发转移率高于低表达肝癌患者,而生存率低于低表达肝癌患者(P<0.01)。结论 肝癌患者血清miR-143、miR-145表达水平升高,其高表达对肝癌患者预后有明显影响,可作为肝癌预后的评估指标。
