Clin Endocrinol:BRAF基因多态性与中国人甲状腺乳头状癌有关

2015-05-10 MedSci MedSci原创

背景:甲状腺乳头状癌(PTC),占甲状腺癌的80%以上,并且这个数据还在逐年增长。近年,研究认为BRAF基因的单核苷酸多态性(SNPs)是PTC的广泛认可的风险因素。本研究目的是,检测中国人中BRAF常见的基因突变是否与PTC的发生风险显著相关。 方法:我们通过<span lang="EN-US" style="font-size:12.0pt;font-family:Times-Roman

背景:甲状腺乳头状癌(PTC),占甲状腺癌的80%以上,并且这个数据还在逐年增长。近年,研究认为BRAF基因的单核苷酸多态性(SNPs)是PTC的广泛认可的风险因素。本研究目的是,检测中国人中BRAF常见的基因突变是否与PTC的发生风险显著相关。

方法:我们通过Haploview 4.2 软件在HapMap数据库中,筛选出四个BRAF的SNPs位点,如:rs11762469, rs17623204, rs1267636 和 rs3748093。选择618名个体留取血样,其中206名PTC患者,412名健康对照者。然后使用PCR-RFLP技术,将这四个SNPs进行基因分型。然后使用student t检验和卡方检验,评估BRAF基因多态性与PTC风险因素的关系。

结果:在等位基因模型中,SNP rs3748093的基因突变与PTC发生风险增加显著相关(等位基因A vs. T,OR= 1.68, 95% CI = 1.16-2.43, P = 0.006);在显性基因模型中(TA +AA vs. TT,
OR = 1.64, 95% CI = 1.08-2.48, P = 0.019),在纯合子基因模型中(AA vs. TT, OR = 2.94, 95% CI= 1.00-8.61, P = 0.040)。然而,其他三个SNPs(rs11762469,rs17623204, rs1267636),与PTC风险因素没有相关性。

结论:研究结果显示,BRAF基因中SNP rs3748093的等位基因A,在中国人中与PTC的发生风险显著相关。目前,需要进一步探索PTC的发病机制来证实本结论的意义。

JCEM:雌激素诱导甲状腺乳头状癌细胞的自噬

甲状腺乳头状癌(PTC)的发生率在性别中的比例是女:男(1:3),关于性别差异的风险因素知之甚少。越来越多的研究认为雌激素在甲状腺肿瘤的发生中起重要作用,但是相关的机制并不清楚。近来有研究发现雌激素受体α(ER-α)可通过刺激活性氧的生成和胞外信号调节激酶诱导PTC的自噬。 研究者分析了ER-α在PTC患者甲状腺组织中的表达。通过化学和基因技术抑制PTC细胞自噬,检测PTC细胞的活力、增殖和
