NINEIN serves an essential role in centrosome function as a microtubule organizing center, and in the reformation of the interphase centrosome architecture following mitosis. In the present study, the association between Pro1111Ala (rs2236316), a missense single nucleotide polymorphism, and the risk of colorectal cancer (CRC), related to smoking and alcohol consumption habits in 200 patients with CRC and 1,141 cancer-free control participants were assessed in a case-control study performed in Japan. The results showed that the Ala/Ala genotype compared with the Pro/Pro genotype was significantly more associated with an increased risk of CRC, and the males with the Ala/Ala genotype exhibited a significantly increased risk of CRC compared with those with Pro/Pro and Pro/Ala genotypes. Stratified analyses of the Ala/Ala genotype with CRC risk further showed an increased association in never/light drinkers (<23 g of ethanol/day), in male never/light drinkers and in male patients with rectal cancer. These findings suggest that the genetic variant of the Pro1111Ala polymorphism has a significant effect on CRC susceptibility in the Japanese population.
NINEIN作为微管组织中心在中心体功能中发挥着重要作用,并且在有丝分裂后间期中心体结构的重塑中也发挥着重要作用。在本研究中,在日本进行的一项病例对照研究中,评估了错义单核苷酸多态性Pro1111Ala(rs2236316)与200例结直肠癌(CRC)患者和1141名无癌对照参与者的吸烟和饮酒习惯相关的结直肠癌(CRC)风险之间的关联。结果表明,与Pro/Pro基因型相比,Ala/Ala基因型与CRC风险增加显著相关,并且与Pro/Pro和Pro/Ala基因型的男性相比,Ala/Ala基因型的男性患CRC的风险显著增加。对Ala/Ala基因型与CRC风险进行分层分析进一步表明,从不饮酒/少量饮酒者(<23克乙醇/天)、男性从不饮酒/少量饮酒者以及男性直肠癌患者中的关联增加。这些发现表明,Pro1111Ala多态性的基因变异对日本人群的CRC易感性有显著影响。
