Mol Carcinogen: 钙摄入量对结直肠癌风险的影响

2017-10-19 MedSci MedSci原创

钙在细胞信号、增殖和死亡中起着关键作用。以前的研究探讨膳食钙摄入量与结直肠癌之间的关系有矛盾的结果,可能是由于没有考虑肾脏钙的再吸收变化。Qi Dai博士及其同事研究了参与田纳西结肠直肠息肉研究的患者参与钙重吸收与结肠直肠腺瘤(癌前病变)的风险相关的基因变化。他们发现,钙离子交换蛋白与钙的摄入在结直肠腺瘤风险中相互作用。他们进一步发现,钙摄入量超过1000毫克/天的三个钙重吸收基因中的两个变异携带


钙在细胞信号、增殖和死亡中起着关键作用。以前的研究探讨膳食钙摄入量与结直肠癌之间的关系有矛盾的结果,可能是由于没有考虑肾脏钙的再吸收变化。

Qi Dai博士及其同事研究了参与田纳西结肠直肠息肉研究的患者参与钙重吸收与结肠直肠腺瘤(癌前病变)的风险相关的基因变化。他们发现,钙离子交换蛋白与钙的摄入在结直肠腺瘤风险中相互作用。

他们进一步发现,钙摄入量超过1000毫克/天的三个钙重吸收基因中的两个变异携带者与低钙摄入者相比,患腺瘤的可能性要低57%。

这一发现发表在10月份的分子致癌研究报告中,它显示了钙摄入量对某些基因变异个体的保护作用,并可能为预防结肠直肠癌和癌症提供一种新的方法。
